CalvinHobbes Posted March 29 Share Posted March 29 Hmmm, a bit concerned. The mvhr guy visited and was slightly shocked at how high the ceiling was (new build, vaulted, don't ask, hindsight is fecking wonderful). He said he could put the vents into the walls as high as he could. However, if heat rises, should it not be at the highest point? Link to comment Share on other sites More sharing options...
jack Posted March 29 Share Posted March 29 I wouldn't worry about it. Does it really matter if the air right up at the ceiling isn't quite as fresh as it as at head height? 1 Link to comment Share on other sites More sharing options...
Gone West Posted March 29 Share Posted March 29 (edited) We had vaulted ceilings upstairs and had the bedroom supply vents in the wall around 600mm above the floor. The bathroom and ensuite extracts were in the wall near the ceiling. Edited March 29 by Gone West 1 Link to comment Share on other sites More sharing options...
Bramco Posted March 29 Share Posted March 29 Our vaulted bedrooms have the vents on the walls, while the vaulted living room/dining room/kitchen have them on the ceiling. Can't say we've noticed any difference. The issue with the ones in the living space was more to do with ensuring the battens for the ceiling were deep enough to take the pipes and the vents.

There are good advantages As the air enters the house it is slightly cooler than the house air, the warm air, pre heats the air so it cannot be felt. My living room terminals are at about 4m high. 1 Link to comment Share on other sites More sharing options...
Andehh Posted March 29 Share Posted March 29 Most of our main rooms are 4m high, MVHR does the job fine at that height. Link to comment Share on other sites More sharing options...

You don’t spend any time floating around up there, so it’ll never be an issue. Comfort is perceived by the occupant, so if you are at the right temp and not turning purple, game on 1 Link to comment Share on other sites More sharing options...
Adsibob Posted March 29 Share Posted March 29 Thermodynamics is more complicated than just “heat rises”. Yes, heat rises, but there will be small pressure changes causing movements in other directions. E.g suction of air into the vent will also draw down air from above, when that air moves down, it will be replaced by other air. So you are all good. 1 Link to comment Share on other sites More sharing options...
