Where should the vents be?


Recommended Posts

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?

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.

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.

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 :)

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.
