    Pat, Thanks. Longtime readers of GBA will remember Marc Rosenbaum's review of an innovative product from Ecodrain -- a horizontal drainwater heat recovery device. Here is a link:

    That may be cheaper than rebuilding the masonry chimney(?) You'll probably need to install safety certified insulated chimneys designed for wood stoves, rather than randomly sliding flue liners ...

    Brian, The short answer is that you can do as you propose. Consult with an experienced mason concerning the flue transitions and the metal chimney penetrations. Of course this raises a lot of ...

    I know it's only my hacked version of 'merican, but parsing it correctly helps: "...even if it's heated solely by the electric floor and on continuously under thermostatic control it's not ...

    "it’s definitely better than a vfd." Oh, for sure. Those are huge power hogs. How long have you been running it? I thought the house was still under construction.

    Trevor, Thanks very much for that information. The paragraph shown below comes from the

    Mr. Holladay, You are correct. And thanks for your valuable suggestions. Corey

    Reid, During his presentation, Brian Just cited one study that showed deleterious cognitive effects resulting from sleeping in rooms with CO2 above 1000 ppm. The Danish study was

    Optional CO2 sensors that integrate with the HRV/ERV are already standard offerings for the premier brands. Zehnder, UltimateAir and Jablotron all have them. I'm sure there are others.

    It works great so far. No problems. I don’t think that it’s higher energy per volume during steady state. The pump impeller will only move the amount of water required to maintain 50 psi.. ...
  • Reid Baldwin | May 22,2018 01:36 PM EDT
    The studies I am aware of have set the target of 800-1000 ppm because that is the level at which cognitive function seems to begin decreasing. When I am sleeping, how much cognitive function do I ...

    Corey, Q. "Would it behoove us (the build team) to do away with the Zip and proceed with 1/2" CDX>WRB>Vertical Rainscreen>Hardie?" A. If I understand correctly, you aren't "doing away with the ...
  • Calum Wilde | May 22,2018 01:13 PM EDT
    I'm really curious to hear what your experience will be with the cycle stop valve. I've looked at it a couple of times but it seems that all roads lead to bad reviews. On the pro side is the ...

    Thanks for the replies, guys! Mr. Holliday- 1. My name is Corey Eshelman 2. The CDX on the interior stud wall is installed on the exterior side of said wall. ...
  • Martin Holladay | May 22,2018 12:33 PM EDT
    David, It sounds like you understand the situation fairly well. You might want to begin documenting the situation by communicating with your contractor via registered letters (dated, of course). ...
  • Dana Dorsett | May 22,2018 12:00 PM EDT
    With GSHP vs. ASHP (air source heat pump) it's a matter of upfront cost/lifecycle cost and design risk. Air is pretty much the same everywhere, and weather data sets can tell you with reasonable ...
  • Eric Sandeen | May 22,2018 12:00 PM EDT
    Thanks for the detailed answers on expected energy use. ~500kWh/ year isn't too bad I guess; I was hung up on electric resistance heat as a source compared to our efficient boiler... in ...

    Corca, Q. "If we did end up having to use a conventional, sheet type WRB could we eliminate the need of a rain screen by using Tyvek DrainWrap or HydroGap?" A. Wrinkled housewraps provide some ...

    Corca, Q. "If the Zip is used on the exterior double stud would air sealing/taping the interior sheathed wall still be necessary?" A. If you care about reducing air leakage, it usually makes ...
  • Malcolm Taylor | May 22,2018 11:12 AM EDT
    Corca, "1/2" vertical furring for rainscreen, 3/8" horizontal furring (to accomodate for Hardie board and batt siding." Can you clarify why the second layer of furring is necessary? ...
