Fans and pipechases

[kylegordon]

Evening all,

Just in need of a little advice. We have a converted loft that loves to collect the warmth from the rooms below. I'd like to duct the ceiling level air down to the ground floor in order to recirculate the warmth. The ideal destination is the kitchen.

There's a pipechase that would be ideal for carrying this air. Is it permissable to have a ventilation fan gently shoving the air down, or are pipechases specifically for pipes and cabling?

Cheers

Kyle

that hot air upstairs will contain quite a bit of moisture. are you sure you want to re-circulate it?

have you considered perhaps using a door?

What??? In the Ceiling??

Well, a door was considered, but due to where the stairs enter the loft, and the peak of the ceiling, we'd need some sort of concertina door that goes from full width into something about 6" wide

Also, the wife is Danish, loves open plan, and would do away with doors wherever possible!

There's also curtains and sliding doors, but... uurgh.

Just how moist does air get when it rises 2 storeys of your average 2 person family, 3 bed Wimpey semi? The bathroom is downstairs too, so wouldn't be introducing moisture into the flow.

The heat still rises, if not into the loft then into the bedrooms if it has nowhere else to go. It would still be nice to recirculate it (cheap) or extract and recycle the heat (expensive)

Hope this helps!

It's not as simple as providing a pipe or duct for air to move of its own accord or with a fan - the fan will actually cool the air quite a bit before it re-emerges and will no longer be warm air

You really don't want to recirculate stale, moist air.

The nearest thing would be for you to install a proper whole house ventilation system with a central fan and filter unit. But, it would need some form of re-heat - which would defeat the object of what you are trying to achieve.
