    Thanks for the thoughts and advice. Martin-I'll remember the idea of not having a bath fan and using the HRV unit in bathrooms to eliminate the need for powered ventilation in some applications. ...

    Chicken, You have a dispute with your contractor. I have no reason to doubt what you are telling us. That said, this type of complicated dispute is impossible to resolve on a web forum. Clearly, ...

    Steven, I'm not sure which of my comments you perceive as "careless," but I'm guessing that it was my advice to use a drying rack indoors to dry laundry. I'm also guessing that you are worried ...

    Calum, Thanks for your comments. Here's where we agree: When the words of a writer are confusing to readers, the writer has failed to achieve the desired goal, which is communication. I think ...

    Martin, Re: abreviations I think it would be fair to say that your experience doesn't reflect that of the average user's. For what I assume the demographic is here, the technical terms are ...

    Hi Dana, This is a Mitsubishi hyper-heat system. It's the smallest central ducted system they make at 30k BTU. It's just got a pretty poor turn down ratio. Min output is 18k BTU at any ...

    Stephen, For your "agreement" that Martin's comments are careless to be useful, or have any weight, you need to at least make a case for why you think that way. It does seem strange to come ...

    Stephen: If the MINIMUM output of the compressor at +47F is nearly the same as your design heat load, it's WAY oversized! If it's that high because you installed 5-6 compressors on seperate ...

    Red LEDs emit a small amount in the near infrared, but there are also high efficiency near-infrared LEDs out there used for every thing from TV remote controls to security cameras. IF a large ...

    I agree. M.Howladay’s comment seems to be a bit careless. But this reminds me of other comments he has made to me on other subjects. I’ll just ignore him.

    The difference is that the few inches of foam in the middle is an adequate vapor retarder, whereas fiberglass batting is EXTREMELY vapor permeable, even air-permeable, which would allow moisture ...

    Not sure what you mean by inconsistent or not fact based. Every article he publishes is footnoted and referenced. If you want to keep drinking the Kool-aid and keep your head in the sand that is ...

    It looks like you can find gimbal lights in smaller sizes. Consider having a local shop make up some "goof" rings to reduce the size of the opening. I had an issue with the hole size on my ...

    @David: Do you know the relative heat load of the rooms and the size of the head units? I'm concerned because the heat pump I'm putting in has a minimum output of 18k BTU, and the design heat ...

    But if I stuff the 9” (top section) of space with any insulation wouldn’t that cause the same issue as having r30? Meaning exterior would be too cold?
  • Dana Dorsett | Jan 20,2018 12:18 PM EST
    I understood that you meant the R30 fiberglass to be on the above ground section, and with R30 in the walls the exterior sheathing would be too cold in winter to skip the interior vapor retarder, ...
