Thanks for the links. I'll give those a look. Nice one.

Thanks. I'll look those up. I take it you DIY'd it all yourself?

Hi again. I'm getting to the point where I'm going to buy a unit. The three manufacturers I'm looking at at Envirovent, Vent axia, and KAWA vent. Are these any good? If not then which brand would you buy? Cheers.

Thanks, everyone. I've got the info I needed. I've got more questions, but I'll start a new post. Cheers

All vents will be in the ceiling. Only one vent will be near a seating area and that one is in the living room. The rest will be as far away from beds etc as possible. You mention coanda effect. I take it general vents are just going to push the air out in a specific direction? Cheers.

Hi, thank you. We have already got a heatpump and underfloor heating. Do you think an a2a would be better than mvhr?

Hi and thanks for the info. I have looked at other types of ventilation but it will have to be somewhat heated due to the wife not liking draughts. Air tightness is something we are going for, but it's a work in process type thing. Once everything is done then the place will be quite air tight. When you say vapour protection what do you mean? I was going to use insulated ducting, would I need to do anything extra? Cheers.

Hi. Thanks for the welcome and reply. Location: It probably isn't the only place it can go. I just figured it'd be the easier to route the ducting. I've never even considered about other places. Thank you, I'llb look for other places it can go. Passiv/Top up heating: Yep, the idea for the extra heating loop was to help the incoming air be the same or higher than what's already in the house. The reason behind this is mainly because my wife seemingly feels every draught within a 75 mile area!! So if I can get the incoming air higher than the room temps it'll be much better for me. Air tightness: It is a concern with everything we've done so far. We've ripped out old rotten floors and insulated and sealed as possible. Taped the joints. Same goes with the roof that we've renovated so far. It won't ever be near passivhaus standard though.

Hi everyone. So, here we go, we are in the midst of renovating a 1890s bungalow and are wanting to fit an mvhr system pretty soon. At the moment we've put in underfloor heating. Heatpump. Insulation etc etc. My question is about the mvhr unit itself... Would it be a good to sit it on its own heated concrete plinth/slab in the roof? Or should I forget that idea and just install a loop directly in to the unit? Or both? Or neither? Would it be a good idea to 'build' an insulated room around the mvhr unit itself? Because of where we are at with the renovation then I can pretty add what is needed as I go along. It wouldn't take too long to add strength to the joists, add an extra heating loop to our underfloor heating manifold specifically for the mvhr unit. Good idea? Terrible idea? Any insight, or other ideas are most welcome. Cheers.
