    I came across this old thred here and it was interesting to see how HRV has become more mainstream since.

    Anyway I met with the MHRV unit supplier and we chatted about the system to some extent. One question I have is where to fit the unit. In the old thread (see above) some people said it was a good idea to have it installed inside the thermal envelope. It would be more efficient and also much easier to get to change filters.

    If anyone has any advice it would be great to hear. Thanks. :)

    I would always advise inside the thermal envelope. Exact location is layout specific but the plant room (if there is one) can be a suitable location

    I've a really large "hot press" and decent sized utility. I suppose the "hot press" is best as it's a bit closer to the in and outlets (roof) and a bit more central in a vertical way - the ducts will run in the attic space and the ground floor ceiling void. I would treasure the space in the utility more also.

    inside the thermal envolpe & air-tightness envelope. the next question is whether can you fit the HRV ducts..

    Welcome to the Fat Finger Club!

    Well for the first floor ducting we'll be putting the ducts in the attic. They come pre-insulated and we'll also be burying them under the attic insulation.

    The advantage I see with this is that the ducts will be easy to get at in future if required.
