I started looking at energy-efficient ones, thinking about what a fabulous experience we’ve had with our energy and water-efficient <a href="http://www.ourhomeenergy.blogspot.com/2008/03/staber-washer.html">Staber washer.</a> As usual, I searched with <a href="http://www.dogpile.com/">dogpile.com</a> for articles, reviews, and stores and I spent some time on <a href="http://www.consumerreports.org/">ConsumerReports.org.</a><br />
<br />
Consumer Reports ratings on energy use are from their extensive testing, not just the yellow labels on new appliances, so they helped me to zero in on eco-friendly dishwashers. CR also said that sparkling performance starts at about $500 or less, but those are louder than more expensive ones. Most conventional dishwashers fit a 24-inch-wide space under a kitchen countertop and attach to a hot-water pipe, drain, and electrical line. That was true for ours. It was also 34" high, so a replacement had to be that or lower to fit under our countertop, but most have adjustable feet. So the standard 24”-width size meant a wide selection.<br />

So, like with the clothes washer, I considered not just energy and water efficiency, but also cleaning power, noise level, and ease of loading and unloading.
My top contenders were Whirlpool and Bosch. I went to Lowes and looked at their floor models. When I was looking at a Bosch, a salesperson suggested I use a rinsing agent with that one to get the dishes dryer. I said we planned to open the door and let the dishes air dry. Why pay to do something that will happen anyway? He said that we were the perfect customers for the Bosch. I chose a mid-range Bosch that was on sale, and was described as extremely quiet (48 decibels).<br />
<br />
We try to run the dishwasher after 6 pm, when people use less energy, to avoid contributing to situations that require energy companies to power up the dirtier power plants. We use the “normal” cycle, which doesn’t include drying. This dishwasher is so quiet, it's easy to think it's not running! So it shines a dot of light on the floor under it to SHOW that it's running. It has a “manual filter” that I clean every few months, and fold-down tines and an upper rack that we can lower for tall items. And I enjoy (yes, enjoy) using the silverware tray that keeps the forks, knives and spoons from touching so they get cleaner. When the dryer beeps that it’s finished, we turn it off, open the door, and pull out the racks. The steamy water evaporates thoroughly by morning. After a year and a half, we can still recommend this Bosch dishwasher.Elizabeth J.

We started to make energy-efficiency improvements and behavior changes before taking on more cosmetic changes and in 2007, we used 12,276 kWh. Then we had the energy audit, air sealing, and insulation, and in 2008, we used 7,929 kWh. We continued to make improvements and in 2009, we used 7,391 kWh --half of the kilowatt hours we used in 2006.
<br></br>
Adding the shades and drapes helped to keep our numbers a little lower than they would have been in 2009, since we were not as diligent with the thermostat as in the previous year. We weren't using a dryer for a few months in both 2008 and 2009 years (it quit and we took awhile to replace it). We started using an electric dryer again, especially for jeans, some other cotton clothes, and towels, because the difference in softness is considerable, especially with the towels. We continue to use the drying racks for many clothes.<br />

Thankfully, we continue to see the impressive energy savings we gained by making the earlier changes we did, especially from the energy audit's first recommendations.

In all three rooms, they replaced blinds, which don't insulate well at all, and were heavy and hard to open and close properly. These cellular shades have a push button and operate like a dream and we have really enjoyed them since then. I was concerned I would miss the ability to tilt slats to adjust the light incrementally, but I don't think I have. In the kitchen, I raise them for the plants and it's nice to see outside more easily. In the office, I open them for me and then I close each (there are two) alternately as the afternoon sun hits. Even when they are closed, there is lots of nice light since they are filtering rather than darkening. In our bedroom, there are sheer draperies over them, and it's great to have two insulating layers while relaxing in soft, uplifting light.Elizabeth J.

Last month we paid 11.2 cents per kilowatt hour, which is less than the 11.97 cents per kWh that our distributor BGE charged for their standard mix of power sources including fossil fuels. When the last yearly contract ended, they switched us to month-to-month pricing, varying with the market. So I compared our options. (In Maryland and D.C., electricity is deregulated so you can choose your energy provider, while your energy distributor stays the same.)<br /><br />I had read that Greenbelt Homes Inc., a co-op known for its practical citizenry, recommends a company called Clean Currents to their residents at <a href="http://ghi.coop/SDP/choosegreenpower.pdf">http://ghi.coop/SDP/choosegreenpower.pdf</a>. Clean Currents was listed on BGE's site for me to consider, so I did at <a href="http://www.cleancurrents.com/index.php/C-Green-Overview">http://www.cleancurrents.com/index.php/C-Green-Overview</a>. And I chose to <a href="https://www.cleancurrents.com/index.php/Greener-in-Greenbelt">switch to them</a> with a fixed two-year contract of 100% wind at 10.8 cents per kilowatt hour.<br /><br />Last time I renewed our wind energy contract it cost more than the previous year, which surprised me, but I went ahead anyway. We're investing in clean energy as a practical matter and on principle. I've been pleased to notice more companies such as Pepco and Clean Currents offering wind power since then. I look for the <a href="http://www.green-e.org/">Green-e certification</a> for a respected third-party confirmation that a company is doing alternative energy right. This time we are able to save money over conventional sources. 100% wind electricity now feels really good in terms of both carbon neutrality and wallet leniency.Elizabeth J.

I bought them at <a href="http://www.tuesdaymorning.com">Tuesday Morning.</a> So we have the two layers over the window, and the natural fibers hopefully won't give off any indoor air pollution. They are not as room darkening as the polyester-lined draperies intended for that. So they aren't keeping out quite as much light and therefore heat this summer, but the room is a bit cheerier to walk through in the daytime even with everything all closed up.Elizabeth J.

It had an ionizer that made the dust drop to surfaces, but I read on Consumer Reports online that ionizers create ozone, which isn't good for you. That purifier let you turn off the ionizer and still run the HEPA filter, so we did that. After the unit stopped working, we didn't replace it. Then I was given a peace lily and I learned that <a href="http://learngardening.blogspot.com/2009/02/peace-lily-your-free-air-purifier.html">peace lilies purify the air.</a> Without using any electricity. And it's much prettier than the electric kind. <br /><br />OK, it doesn't filter dust. We have a furnace filter doing that now anyway, and according to Consumer Reports, doing a better job of it than the air purifier. But the peace lily removes the toxic gases that furniture, drapes, carpet and computers often give off. And it creates oxygen. Makes me breathe easier.<br /><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEityRzWW9PZdU0WkQpnI-fK8B5_5J-4ns0FNH6xmHFto9RGO25infzVG2NhOLsSGzQmNdjWPh1_x5QR7K3fJanKId6OBRGdLoopKRyBEVPn0PLTA7hWgZIHZIJi-CWSDUCqmvc6Ke5oVZY/s400/PeacLily.jpg" border="0" alt="Peace Lily" id="BLOGGER_PHOTO_ID_5364829129490118658" />Elizabeth J.

This has been quite useful since the old dryer quit working in November. We decided to hold off on buying another dryer and see what it was like to just hang everything to dry. Why not save some more energy, at least for a few months? The dryer is electric, so the savings are shown on this chart of our electricity use (in kWh). <br /><img style="margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 400px; height: 359px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg3dWZxfpGHNVZuTBi1g7osqG-QXJP2gvSqDyktAMKoBouNAcDN_6giy9KO-xtf4QnNNqywfPb87wYDXqo5wj6dYJTV_ukdxAkX17RxlsATxeL4csyrh41qJgbT7IQs_Shb0R-NEe_gkH8/s400/electA09.gif" border="0" alt="Electric_use_without_dryer" id="BLOGGER_PHOTO_ID_5330601474309293186" align="center" /><br /><br />The wood drying rack we set up as needed in the master bedroom for delicates was no longer enough, so Santa brought us another one like it. We've been hanging shirts and pants to dry right on their hangers and perching them on the molding above the closet. Everything has dried just fine, except the old, thin towels which become like cardboard. The newer, fluffy towels are soft after air-drying. We noticed a little bit of added humidity in the bedroom, which was very welcome in the cold, dry months. We may move the drying clothes to a bathroom or the kitchen or possibly outside if the humidity becomes bothersome as the weather gets warmer.<br /><br />This updated chart shows our natural gas use (in Therms) for heating over the same period.<br /><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 400px; height: 360px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZsfDCCSG_0FUuLoZNS6IAQFdoWYSx_QfvaOrfJSVudb7tlkjOrIMNTPtCi1SocE6CW5AaTh_nxnrBiV82DqMfU_3E72tP6UY1f5_tfbdUHV9VtHXoUrg8quUyx0ILfeNT6aCWQkyv2FQ/s400/gasA09.gif" border="0" alt="Gas use update April 09" id="BLOGGER_PHOTO_ID_5330606415106351634" />Elizabeth J.

As far as windows go. Even two panes of glass do not give you close to the insulation value (or R-value) of an insulated wall. He suggested that "shades and drapes" would be a good cost-effective solution to better insulate the windows than our blinds. Traditional blinds, with gaps between every row, do not create a solid cushion of air between the window and the room.<br /><br />My Internet research indicates that the cellular shades (the pleats have a honeycomb shape if you look at them from the side) are probably the most insulating type of shades available. I found <a href="http://http://www.redishade.com/easytouchcellularshades.html">Redi Shade cellular fabric shades</a> that you cut to size yourself at Costco and at Tuesday Morning. These have a single layer of cells and let in a nice glow of light. <a href="http://www.selectblinds.com/cellularshades/38doublecell-lightfilter-cellular-shades.html">Cellular shades with a second layer of cells</a> darken rooms and offer more insulation. I also found a <a href="http://www.selectblinds.com/cellularshades/vu-thru-room-darkening-insulating-shades.html">cellular shade/blind combination</a> that looks promising.<br /><br />We put four of them up in the living room with relative ease (we used the brackets so we can take them down to paint instead of the adhesive option, which would have been really simple). They look great, and a great deal better than the old blinds. They are cordless and pressing the button to raise and lower them is fun and easy. We put up draperies too, so that is our second layer.<br /><br />We've been opening the shades and drapes up and letting the daylight warm the house. We used to open, but not raise, the old blinds in that room and it's been great to have an unobstructed view of the trees and grass waking up for Spring. We haven't put all of the shades up yet, but I look forward to have a tighter building envelope at night while it's still cold. I hope to open them after the heat of the day in the summer, to continue enjoying the nice views.Elizabeth J.

I said that Battic Door, the company that makes the fireplace damper pillow we bought, also makes an attic door cover (hence their name). He said the low cost made that worth trying.<br /><br />Using the instructions at <a href="http://www.batticdoor.com/StairCover.htm">http://www.batticdoor.com/StairCover.htm</a>, I measured the attic opening. I chose the cover with the reflective shield and insulation. It came within two days. Once assembled, it would be too big to get through the opening, so I took the pieces into the attic, folded the cardboard into a box, set the insulation into the reflective cover and then slid the box into the tight, shiny cover. I couldn't set it in place immediately, though, because the top of the cover, which is taller than I realized with the insulation added, was too tall on one side of the opening for the slanted beams.<br /><br />I used a couple of other boxes to test how to easily make one end of the box fit the angle. The hammer method just made a hole. Making two cuts, refolding and using a lot of mailing tape did the trick. Now the cover fit under the slanted beams to seal the opening. I put the weatherstripping that came with it where the cover meets the wood around the opening. Before it was set in place, I could feel plenty of cold air coming down through the open door, but not anymore. I folded up the stairs and closed the door and it fit.<br /><br />To put away some boxes, I lifted the cover to one side. The next time, my husband suggested I prop it up at an angle using a mop instead, which gave me more room to move boxes. We're pleased with the attic door cover and I highly recommend it.Elizabeth J.

The day of the audit and on a few cold days since, my hand felt a steady stream of cold air along the edges of both. The molding around the brick face of the fireplace fit well and I did not want to mess up the look.<br /><br />I bought a tube of nontoxic caulk: <a href="http://www.geocelusa.com/php/retail/product.php?prdb_product_id=29">Geocel Quick Shield VOC-Free Sealant.</a> I had someone with experience remove the trim around the brick to avoid damaging the wallboard. The gap along both sides was MUCH bigger than I thought it would be: almost half an inch wide. The gap revealed a cavity a few inches wide with NO insulation. So I bought a small bag of fiber glass insulation and we used it all in those spaces, then stuffed in foam backer rod (gray foam tubing) called <a href="http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100067266">Frost King Poly Foam Caulk Saver</a> (1/2" diameter) and applied the caulk. <br /><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 240px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiR8PpUxtR84M2Uj1N8sw_6J5qkX4DEx1gMpNawc0C9PN0DNfy1WZ3jsF135pPobK1VIAeertZ-qXBMXJzx_Hm55zKeyB9Tm8GCW-eJxBH_rdYXibBp14JiJsR5MncaLjswVN1Qw18IUG4/s320/brick_gap.JPG" border="0" alt="gap between wall and brick sealed" id="BLOGGER_PHOTO_ID_5297574626237923154" /><br />We put the molding back and it looks fine. We caulked a new white edge along the sliding glass door, too, and that looks much neater than it did. The caulk worked great with no smell and the tube said it will last 50 years. I now notice a remarkable stillness in those places.Elizabeth J.

How much? Here is a chart comparing our electricity use over the last three years (as of December 2008) in kilowatt hours. <img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 320px; height: 287px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiflCXHjbwqdtCr08s2zQnRmMEvToIKWKZobh2ROrMN07vRreDh8Oo9FYVo0ZEqwK1h-cDL0-8T6iCp8TRRUmJKTgxpod_RdyNQibY7ne2np8BWsp0gP4v4YnDuCTsNkhZuXPOzgov4npc/s320/electric+use+chart.gif" border="0" alt="electric use chart" id="BLOGGER_PHOTO_ID_5275432976414184274" /><br /><br />We saw a nice reduction in 2007 after switching most light bulbs to CFLs and replacing our washer with the Staber washer, along with making an effort to shut lights and computers off when we weren't using them. Then we saw a much bigger reduction after having the attic sealed and adding insulation in January 2008, and comfortably keeping the thermostat lower in the winter and higher in the summer. Here is a chart comparing our natural gas use (in Therms) for heating over the same period.<br /><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 320px; height: 288px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhe6oIAt4ymQKPdHkRenF_ieisXFM2vxz3MBUDHiyFEgQLoXEfDrovHXA_LbK6qbzeXpJmueVzs6RAkEyx3VVrqN2rkTRu4lHkeCFebzp4ZUoP1bG-boUcQPB5V4BRjrtMJ1r1D-WdBxxk/s320/gas+use+chart.gif" border="0" alt="gas use chart" id="BLOGGER_PHOTO_ID_5275433297601662946" /><br /><br />We'll see how much more we can save as we do more of our energy audit To Do list, and continue to learn better habits. We're not approaching the <a href="http://www.annapolisgreen.com/pdf/Wnegrad-conserve-energy.pdf">$36.76 July power bill of the former Maryland senator and Chesapeake Bay activist Sam Weingrad</a>, but in July 2008 we used half the electricity that we used two years before.Elizabeth J.

On June 24th, Home Depot launched a national CFL recycling program:<br /><a href="http://www6.homedepot.com/ecooptions/index.html?">http://www6.homedepot.com/ecooptions/index.html?</a> So now you can bring in expired, unbroken ones when you go to buy a new one. Most of ours have come from Home Depot, so that's fitting. IKEA, True Value, and Whole Foods already accepted burned-out ones. So far, we've broken a couple on hard surfaces, and the clean-up was easy, if a little spooky the first time (leave, wait, scoop with cardboard and then a damp paper towel into a plastic bag, put in the trash). Broken CFLs go in the regular trash since the mercury has mostly been released into the air.<br /><br />Wendy Reed, who manages EPA's Energy Star program, says that even though fluorescent bulbs contain mercury, using them contributes less mercury to the environment than using regular incandescent bulbs. "That's because they use less electricity and coal-fired power plants are the biggest source of mercury emissions in the air."<br /><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 240px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_OX9fQD1ubWPOrBXhJnIXHG5v2ucw4OA8ywrg8qbOH86WcUXwRygJWhdw5NpJdqPX7LYiw7JcuV4o-TBnF2M8WdzIYzWoi4vWgQ1RlViBafthIv9eatete1Qgs-nok7TAjD1ZZzcfBDE/s320/bathmirrorCFL.JPG" border="0" alt="bath mirror CFL" id="BLOGGER_PHOTO_ID_5275601281795630978" /><br /><br />The Maryland Department of the Environment says CFL bulbs contain up to 5 milligrams of mercury, the amount that would cover the tip of a ballpoint pen, as compared to older home thermostats and mercury fever thermometers, which contain between 500 to 30,000 milligrams of mercury. Most of our exposure comes from eating fish. The Maryland Department of the Environment urges consumers to use care when handling CFLs by screwing and unscrewing the bulb by the base. If a CFL bulb breaks, the amount of mercury released can evaporate into the air where it will likely remain at a level below safety standards set by the Occupational Health and Safety Administration.<br /><br />In the DC metro area, many local governments accept expired CFLs at their periodic household hazardous waste (HHW) collection events or permanent HHW drop off sites: see <a href="http://www.mwcog.org/dep/gorecycle/cfl.htm">http://www.mwcog.org/dep/gorecycle/cfl.htm</a>. <br /><br />And if you get one of those emails forwarded to you about how dangerous CFLs are, send the person you know this link to Snopes.com, the great muckraking site: <a href="http://www.snopes.com/medical/toxins/cfl.asp">http://www.snopes.com/medical/toxins/cfl.asp</a>.

He said with surprise, "That's a BoGo Light!" I was surprised and pleased that he recognized it. He told me that he actually gives them to clients and forgot to bring mine that day, but would send it to me! He borrowed my <a href="http://www.bogolight.com/">BoGo solar task light</a>, because it was brighter than his flashlight.<br /><br />I often read by mine in bed after my husband has gone to sleep. If it's getting too dim, in the morning I put it in the window so it can recharge all day. One overcast day has recharged the batteries enough to last many days for me. The real beauty of it is that when you buy one, one is donated to people who don't otherwise have a safe source of light. I've given several as gifts and I think it's a great flashlight, a neat way to save some energy and a powerful gift to those who truly rely on it after dark.<br /><br />Our auditor did remember to bring me a BoGo Light when he came back. Since I already had one, I gave it as a gift, to enlighten someone else.Elizabeth J.

She said that from seeing the effects of climate change on animal habitat, she believes there is a five-to-seven year window for us to take action. I hope she is wrong and we have more time. Heck, I hope many things, but as Mel Brooks said, "Hope for the best and prepare for the worst."<br /><br />So I plugged in my computer and looked for good ideas. I found my way to the <a href="http://www.eere.energy.gov/greenpower/buying/buying_power.shtml">U.S. Department of Energy's Green Power Network site</a> and learned that we could power our house with renewable energy. I shared the good news with my husband, who like me was surprised and pleased that it's available in our state. Nobody told us! And we watch a lot of TV! I followed the links and chose a Green-e certified provider generating wind power in Maryland and neighboring Pennsylvania: <a href="http://www.commerceenergy.com">http://www.commerceenergy.com.</a> Using Commerce Energy's site, I quickly and easily switched our energy supply from Baltimore Gas & Electric (BGE)'s standard mix of 60% coal/30% nuclear/10% alternative to Commerce Energy's 100% wind-generated power.<br /><br />When I compared the cost, it looked like it would be around $20-25 more monthly, but our contract has a fixed rate for one year. So it could be cheaper before long. Anyway, we had already reduced our energy costs more than enough to make up the difference. And making that decision felt good to us.<br /><br />Commerce Energy notified BGE and our power switched over in September. BGE continues to distribute the power to us and bill us, so after that visit to Commerce Energy's Web site, we haven't had to do anything differently. We've been powered by wind for over seven months and our electricity is reliable and consistent, no different than before. And knowing what's behind it continues to feel really good.Elizabeth J.

Then in January we had an energy audit that led to air-sealing a few big gaps and adding cellulose insulation to our attic. Ten days later, I gave a <a href="http://ourhomeenergy.blogspot.com/2008/02/our-home-energy-audit-on-nbc4s-going.html">TV interview for NBC4 news</a> that mentions we'd turned down our thermostat four degrees. But that's not where it stopped!<br /><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhsXAKO5wJ0lZthWkHZwDzR_Yefuk55tOU_5j09h2LlTFWWGowMhPZoWHdz7x-hpv7GWYitGyrPzF5dPsD3ApuRElUft3dloIjAPDtGfmM_Ffy9_6liGhdoFjic8zxadecnfNmHJ0TKC9o/s320/cellulose.JPG" border="0" alt="cellulose insulation"id="BLOGGER_PHOTO_ID_5189629587788212546" /><br />We turned down the thermostat one degree every few nights until we got down to 58 degrees. It's still true that it's a lot warmer upstairs than down (other suggestions from our audit should help with that): most winter days when we're home and evenings downstairs, 67 has been O.K. since the work. But with a blanket of 85% recycled paper above us, we've been cozy in our bed at nine degrees lower. And Spring came before we were finished experimenting!<br /><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh0C7-a3BaIPU2Iq67BRpRJEE7zBzufA0HTLW9Rh07xBdb7iCyilAFkTjHxq-gvZrkCkgOsWGI4Efc9i24drT1vilwGMg2kq9UdSwnje1nTru_0Kwcmu7dzgpmjvYJ80RMf8TrPM9nbgLs/s320/thermostat_58.jpg" border="0" alt="thermostat at 58"id="BLOGGER_PHOTO_ID_5189617424440830258" /><br /><br />For details on our audit, see <a href="http://ourhomeenergy.blogspot.com/2008/02/our-home-energy-audit_12.html">Our Home Energy Audit</a> and for a quick photo tour of the work, see <a href="http://ourhomeenergy.blogspot.com/2008/02/air-sealing-insulation.html">Air Sealing & Insulation.</a>Elizabeth J.

I read that the chemicals in most dryer sheets are toxic and potentially harmful to humans, and these cloth ones don't use chemicals. Somehow it's the weave that removes the static & makes the clothes softer. They are reusable for 500 loads. That's makes them cheaper, too. They also don't leave the residue that clogs the lint filter, the way most dryer sheets do, so they keep the dryer working efficiently. That's probably why these don't void dryer warranties. I bought them at <a href="http://www.staticeliminator.us">http://www.staticeliminator.us</a>. They are the two striped cloths in the photo.<br /><br />In the summer and fall after we switched, they made the clothes soft and free of static. We did notice a bit more static in the winter. Our indoor air gets extremely dry in the winter. They still did an acceptable job, though. We could add some white vinegar to the wash, but I only did it a couple of times and then forgot about it, since the clothes, towels, sheets, napkins, and tablecloths have all been fine.Elizabeth J.

It's a top-loader that runs like a front-loader. After you close the top of the basket with your laundry in it, it rotates on a horizontal axis. Though this type of machine is popular in Europe, the Staber is the only one made in the U.S.<br /><br />It's on the Energy Star list of efficient washers. It's not in the very highest efficiency Energy Star tier because Energy Star doesn't subtract the agitator to judge volume (an ordinary top-loader with this drum size could not hold a full load). Yet it holds a full load (approx. 18 pounds), because we can fill it completely full since there is no agitator and no front-door gasket to avoid (front-loaders often leak when clothes get caught in the door gasket). So it uses less energy, less water and much less normal detergent than most washers, and it does a load in about the same amount of time as our old top-loader. See <a href="http://www.staber.com">http://www.staber.com</a> and be sure to watch the video.<br /><br />The Staber sounded superior to any other washers sold in the U.S. from the specs and the testimonials and forums I read, including Consumer Reports forums (it wasn't included in their tests). It also has the critical advantage of fitting in our small laundry room. Our distant second choice was the Fisher & Paykel Intuitive Eco top loader with flex agitator, but the brand seems to require frequent repairs. Third choice was the Whirlpool LHW0050 front-loader, but while the measurements seemed about right, I wasn't sure that our laundry room doors would have given the front door enough clearance, and front-loader door gaskets seem to require frequent cleaning with bleach to prevent mold.<br /><br />We wash the laundry only in cold water, and the Staber does a better job in cold water than our old top-loading washers. It is gentler on the clothes too, since there is no agitator to stretch or pull them. It gets more soap out of the clothes, which pleases my sensitive skin. After using it for a year, we are both still very pleased with it.<br /><br />After washing a load in the Staber, it's already much dryer from the spin cycle than any washer I've used. With that and the dryer duct replacement and vent cleaning, the laundry dries much sooner. We switched to using the dryer's dryness sensor instead of its timed drying cycle, which makes so much sense I keep having "I could have had a V-8" moments for not switching sooner. Since the clothes are not being overheated, they are not shrinking as much and they are softer.Elizabeth J.

I'd read that homeowners should have the dryer vent cleaned every few years to prevent a fire hazard, so I looked online for how to get that done.<br /><br />I learned that the vinyl/plastic and aluminum foil dryer vents ARE fire hazards. The rigid metal and semi-rigid metal ducts are both much safer. The rigid metal duct is the best choice if your path from the dryer to the opening in the wall or floor is pretty straight, since the escaping air, moisture, and lint encounters the least friction on the way out, drying the clothes that much more efficiently. Our path is like a question mark, so when I called the <a href="http://www.dryerventwizard.com">Dryer Vent Wizard</a> to arrange a cleaning, I asked if he could also replace the old foil vent with a semi-rigid metal dryer vent.<br /><br />Bill from Dryer Vent Wizard came and put in a semi-rigid duct with lots of metal tape to make sure the connection was secure. He cleaned from the dryer all the way to the outside outlet, sending vast plumes of lint into the air. Cough, cough. I came inside. The speed of the air coming out went from 8.2 mph to 15 mph. He said he usually sees a big improvement, but he was impressed. He even raked the leaves on the patio to clean up the lint.<br /><br />He also told me that if we used dryer sheets, they leave a residue that blocks the lint screen. He said I should take an old toothbrush & soap and clean the lint screen every now and then. He said you can tell if it needs it by just holding it under running water, which would pool instead of just going through. I tried it. He was totally right. The lint screen might as well have had clear plastic over it. Then I cleaned it for a few minutes and the water ran straight through it.<br /><br />We looked forward to the clothes drying faster, once we had a working washer.Elizabeth J.

We did the towels and buckets routine. We moved the washer out of its spot. I called a carpet company and they brought ozone generators to quickly finish drying the floor, walls and nearby carpet to prevent mold. I didn't want to worry about water damage from that source again. I didn't want to breathe that amount of concentrated ozone in my home again either.<br /><br />I discovered the Samurai Appliance Repair Man's suggestions for preventing a washer flood in the future at <a href="http://fixitnow.com/2005/03/three-easy-steps-to-total-washing.htm">http://fixitnow.com/2005/03/three-easy-steps-to-total-washing.htm</a>. Confirmed by my research at other sites, the three steps seemed like very good ideas. So I ordered the FloodStop, a smart system that shuts off the faucets if it detects water on the floor. We already had the steel-braided fill hoses, and they had not leaked. I also ordered the leak catcher, which is a plastic "dish" like the one under the dish drainer on the kitchen counter but big enough to sit under the washer.<br /><br /><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhP0z2mKst9TxExfviAgPghIZjj6BVt0dSWDNFdbSrDMfeRu-M9AU6KP1QpBNWdH4byqcNMWccqaCYBoPCeWgU63Uik5oRLIZhiug2oWZety-ofgzxZcL23EXtiJSYHdsjWIPR6Cf934eA/s200/FloodStop+_shutoffs.JPG" border="0" alt="FloodStop shut-off valves" id="BLOGGER_PHOTO_ID_5176699043571329842" /> After the FloodStop arrived, we installed its shut-off valves on both the hot and cold water faucets. We plugged the valves into the control unit. We plugged the moisture sensor into the control unit. We plugged the control unit into the power outlet. We rested the moisture sensor on the floor.<br /><br />Since we'd unplugged the fill hoses from the old washer before moving it out, it was easy to test the FloodStop. We turned on a faucet and splashed a little water onto the sensor. The water immediately stopped. We dried the sensor with a towel and then waited for it to dry completely to test the other faucet. Its shut-off valve worked like a charm, too.<br /><br />Even for the people (not us) who shut off both faucets after every washer use, this is a good idea. Our washer overflowed while we were using it, but we were watching movies with a guest and we didn't notice until the water had covered a surprising distance. I think the water level sensor of the old washer failed. I didn't confirm this because I wasn't willing to give it another chance, and it was a good time for us to switch to an energy-efficient washer. Bottomline: The FloodStop is a clever device that should save a lot of people from a lot of hassle, expense and anxiety.Elizabeth J.

We even wondered if the sockets were bad. I was pleased to find compact fluorescent lightbulbs (CFLs) that were shaped like regular incandescent bulbs and we replaced the porch bulbs to save electricity. Happily, they are lasting a very long time. We've only taken them out to put in yellow bug CFLs for warm weather and then replaced them again with the white ones.<br /><br />Later, we replaced the patio bulb with a CFL too. Later still, we replaced 14 lightbulbs in a fairly short time: ten of them were bathroom vanity lights! One site claimed that if you didn't leave the lights on for hours, it wasn't efficient to switch to CFLs. I think we're vain enough to get our money's worth ;-)<br /><br />Weeks later, we replaced four more lightbulbs. And then a couple more. It's been 23 so far and we still have more to go! It's been tough trying to replace the chandelier bulbs that are on a dimmer, but hopefully soon the CFLs that claim to work on a dimmer will do so very well. For the ones we've been using, reducing the energy used while still enjoying nice lighting is a kick. <a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimCV6tUSOnOJtZGEQKd1H37r-1CR5Rq7w3szLZqw2CtkfTWHbFbTNNcn8cYWgVJbufc2H8kwMl42HoZBl5UK1rlDY_8rL1XtaUpr-68vF2xLRXlEgpO2JSZheYU66hyphenhyphenQL9hDiGdUIPELE/s1600-h/shaped_CFLs.jpg"><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimCV6tUSOnOJtZGEQKd1H37r-1CR5Rq7w3szLZqw2CtkfTWHbFbTNNcn8cYWgVJbufc2H8kwMl42HoZBl5UK1rlDY_8rL1XtaUpr-68vF2xLRXlEgpO2JSZheYU66hyphenhyphenQL9hDiGdUIPELE/s200/shaped_CFLs.jpg" border="0" alt="shaped CFLs" id="BLOGGER_PHOTO_ID_5176702067228306258" /></a><br /><br />I bought some small spiral CFLs at Costco in bulk to put in the lamps where you don't see the bulb and more conventionally-shaped ones at Home Depot.

I thought that would take the chill off our evenings downstairs.<br /><br />A chimney sweep cleaned the gutters, swept the chimney, left a fine black dust on the living room, inspected the chimney and then considerably overpriced a new cap. That's okay, I wasn't going to climb up there with a new cap. He said we had one of the strongest downdrafts he'd ever seen. He left the damper up, saying it would make the downstairs more comfortable without costing us more and that I should test it, at least.<br /><br />We bought a new HEPA vacuum to suck up all the soot and then gleefully let it pull us across every room. We had a couple of glorious little fires using a Duraflame and then a Crackleflame log, which sounds like real wood burning. But the room was no warmer. I was surprised, since my mom's fire heats her family room very well. Of course, she closes the doors to the room. And we have no doors to close off the room from the rest of the house: it's an open floor plan.<br /><br />Days after the fire was out, the room was still colder than before the sweep had come: the experiment failed (What a surprise! Not.). I managed to dislodge the damper instead of shutting it. We put a blanket over the front of the fireplace and watched the gusts inflate and deflate the blanket animatedly. The sweep came back and fixed the damper, and closed it.<br /><br />Months later, to prevent the AC from rushing up the chimney, I was looking at fireplace doors online and found a damper pillow at <a href="http://www.batticdoor.com/fireplacedraftstopper.html">http://www.batticdoor.com/fireplacedraftstopper.html</a>. The Fireplace Draftstopper creates a better seal than a metal damper encrusted with past fire debris. I set the black, plastic inflatable cushion in place and blew it up. It's just as easy to take it out if we want to have a fire.<br /><img style="cursor:pointer; cursor:hand;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg97t_TpMFBPL067RH0oQ2gjC3htwJS2Xq7jhykmVX53m3_fdrzDIBqa0yaqIXcuHXWXI7FAXclOncw3hStFQAXED5TD2SPiSv_QACwRuH7Nslp20ipAsDX2ngK5EkJ4Wstn6DbrIFtLUU/s200/draftstopper2.JPG" border="0" alt="draftstopper"id="BLOGGER_PHOTO_ID_5171472784093454610" /><br />We definitely noticed the strong draft from the fireplace was much weaker with the cover in place. A small draft still comes up from the gaps in the masonry on the firebox floor. It's on the To Do List.<br /><br />Last month, our energy auditor was glad to test a house that had a damper cover. He had recommended this type of solution to others since they are so affordable. We discovered ours had deflated a little over time, so I added some air and he said it helped. I checked it again when I replaced the furnace filter, and I'll make it a habit to do them together each time.Elizabeth J.

The second owners showed off a switch plate perfectly wallpapered to match the leafy pattern on the wall behind it. It really is amazing. And it's pretty tasteful. Both of our moms love it. That works for us, because we've had enough to do with our jobs, cleaning, and unpacking.<br /><br />We did start on the home inspector's list. A Sears tech cleaned and inspected the furnace & the hot water heater and was about to give a clean bill of health, when he saw a rust patch lurking in the back, broaching the final remaining layer of the tank. The home inspector had missed that.<br /><br />I bought a new hot water heater from Home Depot. I replaced a gas one with an electric one for better indoor air quality. That removes a potential fire hazard, too. I didn't know then that gas is the current environmental choice, even though gas isn't renewable, because power plants are a bigger problem. At least I bought one with a 12-year warranty. Ones with longer warranties, according to <a href="http://www.consumerreports.org/cro/appliances/heating-cooling-and-air/water-heaters/waterheater-tips-205-gas-hot-water-heater-electric-hot-water-heater/overview/index.htm?resultPageIndex=1&resultIndex=1&searchTerm=hot%20water%20heater">Consumer Reports,</a> are much more energy-efficient than the models with shorter warranties, because they typically have larger heating elements, thicker insulation, and thicker or longer corrosion-fighting anodes. Yes, this one is much wider than the old one, and though I measured, it was a relief when it fit!<br /><br />Our home energy audit report said that water heating is our second largest single energy use. One recommendation is to insulate approximately 4 feet of the hot and cold pipes as they exit the top of the tank to reduce the convective heat loss. I've been looking at types of insulation to use for this and when I looked at our pipes to see what size to get, I saw that they touch. Yes, the hot water pipe, which felt like it might burn me if I kept touching it, actually touches the icy-feeling cold water pipe! Very close to the top of the tank!! So I'll be getting insulation that fits between them... <br /><br />We already have the hot water heater thermostats set at 120 degrees, which was the factory set temperature, and is often recommended by energy efficiency articles. We've never run out of hot water and it's definitely hot.<br /><br />I wondered later if I should've chosen a tankless hot water heater, but from what I've read we probably would've had to increase the amps to the house to support it! I'm going to look into the AirTap Water Heater Add-On among other options on <a href="http://www.aceee.org/consumerguide/waterheating.htm">http://www.aceee.org/consumerguide/waterheating.htm</a>, which would be a good site to check out if you need to pick out a new one.<br /><hr/><br />Update: I wrapped Armaflex insulation tape around the hot water pipe, overlapping halfway for the first layer and then just a little bit for the second layer. <img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEix8ooHxPH_qC6sYxcDoolhecJQRa-8djLA2YB9EmobepvnrFLXkxuM6Mg8VkFyB_tUI-nw7_WZ2KlPAAlTCWUV4CR3giQijlvJuYpYVh4-bUpa0r0S3b5EDZWR9k532KpzqPHEtKtxoKs/s200/water+pipes.JPG" border="0" alt="water pipes" id="BLOGGER_PHOTO_ID_5171090295780909298" align="left" />I barely managed to get both layers between the two pipes. <img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOFf_aSmdZIFsQ55yALzri1UxEx8xd_z7CswA2eNpzKH3zwG8MS7zO329EihwvQKDx-q-rtK7QEwGmr4QOL7vEAtr8D0BpSRAtNjCCNQL2VRqCh8VKO1BE1FjDspvtZOY-TFEx2qDFnLo/s200/pipes+touch.JPG" border="0" alt="pipes touch" id="BLOGGER_PHOTO_ID_5171091064580055298" />Elizabeth J.

Brad sealed the gaps in the attic with foam, and foamboard where appropriate.<br /><p>Here is the biggest gap, sealed for the first time in the house's 37 years, along the framing void for the master bath.<br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjTIYVjFkTf_y_sEcyw_G0m3D53WAIEa5BwBFjGya2_bpf6ui87UbNn2GUuXeZDK0W_d6pSeAaPIPjDkXvzhwMRzD1Fy-wMfie7GEgih0a6qevItYT6h3mFSGLA669pnR9sYNZG5ovp8qo/s320/sealing_the_void.jpg" alt="Sealing the Framing Void" border="0" height="153" width="204"></p>A common gap is around the furnace flue, like this one:<br /><p><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQWruAXWebzqjhUxrXxMBZg2M0EKezN4NTBvf2JqPpFZucTfC2CZz2a1PzDQPMqO0ZRTP63HwnJ7bwY87dkvVpo9CEYvpsdsPkRVMYZrINhDJgk1UeC041fJlgVQsrFnPy8mQstOBXU3s/s320/furnace_flue.JPG" alt="Furnace Flue Sealing" border="0" height="153" width="204"> </p>Another gap was found hidden under the old insulation over the stairs near the upstairs hall bathroom.

Then they ran the blower door test again and showed a substantial reduction of the air leakage rate. There was still some air leakage. I could feel it in the furnace room, but nothing like the torrent I felt before the work. Thom said it probably wouldn't be cost-effective to tear up the house further to find more leaks. He said that doing more of the recommendations from the audit should take care of our needs.<p>Now the upstairs is wearing a warm sweater. We lowered the thermostat by four degrees right away with the same comfort upstairs. It's been neat to try the thermostat one degree lower each night. Our latest try: 61 degrees was just fine while we slept. So we're saving money at night and when we're in the office, since it's upstairs. We still raise the temp a few degrees when we plan to spend the evening downstairs, a few times a week. The downstairs will continue to improve as we finish more of the recommendations.<br /></p><br /><p>Update: We've been sleeping at 60 degrees comfortably for a few days!</p>Elizabeth J.
