    We have Ditra heat under our bathroom tile floor. It works very well. We generally turn it on thirty minutes or so before a shower. I suspect tiling your entire floor, with heat underneath, won't ...

    CL, I assumed you were using one of the engineered plank click and lock systems. If you are using a glue-down tile and the manufacturer warranties bath installs, I wouldn't worry about ...

    Thanks for the responses. Per the above, any electric product is likely to have the same efficiency (or lack thereof) and the finish floor thermal conductivity will impact the efficiency of the ...

    Bubba, The company with the best products and materials appropriate for stone veneer is MTI. Check out their web site. Two details are attached below. I ...

    Not really helpful to the OP but seems like a good time to bring up an incoming technology that will reduce clothes drying time and energy use drastically. Ultrasonic clothes drying!! Does ...

    Reduce, re-use, recycle (in that order). If you don't feel like using the high-tech, nuclear fusion option (aka a clothesline with the sun), re-using is usually a great option.

    So, what do the fuel use heat load numbers say the load would be at your +26F outside design temp? If you're planning to insulate the basement walls you can knock at least 10% (sometimes 25%) ...

    Lance, do you need to place solar panels on the pent roof? If not, would it work to utilize metal roofing on the pent roof to minimize the snow buildup? Just thinking of ideas....

    We are building in Western Pennsylvania. I believe climate zone 5. We have 2x6 exterior walls with 1/2inch osb. The interior walls will be insulated with the required r value fiberglass ...

    Thank you, Jon! I am scheduled with a local contractor to do the whole house assessment with the door blower and infrared imagining. Will posts the results once it's done.

    Fortunately, Benjamin Obdyke has this note specifically for this situation: http://www.benjaminobdyke.com/uploads/resources/HydroGap_Under_Metal_Cladding_Tech_Bulletin.pdf. I don't think it's ...

    As Martin says, get better air sealing and some outside air ventilation (in Winter). The former should be done by someone with a blower door. If you can't accomplish the latter with passive ...

    Lance, you're right--I did the math without writing it down and did it backwards. The horizontal load on the stud is indeed 300 lbs. Modeling it as a point load on a beam, which is what the ...

    Michael, Is this your forever house? I have been working on my 1830 homes for the past 30 years. At age 40, real wood was the way to go, now at 70, the new Boral looks really good. You might ...
  • Tyler LeClear Vachta | Apr 24,2018 09:56 AM EDT
    Best practice is to include a rainscreen air gap behind the stone veneer with a weep system at the bottom - either stone cavity weeps on the stone ledge or a ventilated weep screed if it's an ...

    A reasonable definition of efficiency would involve useful work - so I'd exclude any heat lost to the underside of the floor. This efficiency will be less than 100% and cork will lower it (as ...
  • Michael Mohr | Apr 24,2018 09:37 AM EDT
    Thanks for the comments Jonathan. Definitely not trying to just get by. We just really like original wood siding - our house still has the original windows we're rebuilding, etc. so we just like ...
  • Sarah Poulin | Apr 24,2018 09:30 AM EDT
    Calum, thanks for your reply! What ended up happening (my original question was from 2 years ago), is we found an AO Smith Hybrid Hot Water Heater at Kent. It came to $2,000 after tax and my ...

    C.L., You also want to confirm that the cork is suitable for wet areas. A lot of the products I've researched are not recommended for baths because they will swell and buckle.
  • Andy Chappell-Dick | Apr 24,2018 09:02 AM EDT
    Carl, this sounds like a great step forward. As a builder who has pushed a project through LEED for Homes, I am the first to gripe about the points and the gaming. But, I have tremendous respect ...
