Underfloor cooling!!

[Nige]

Hi all,
Would it be effective to circulate cold water around the first floor under floor heating system during the summer to cool a property??!!
Wondered if any of you guys had plumbed a system to do so.
Would you need to fit some kind of cooling device or if the water was pumped through the ground floor as well, which is a concrete slab, would that cool it sufficiently. . . . . or is this just a rediculious idea!!!!
Any thoughts appreciated.

never heard of the idea before. i would imagine a cooling loop would have to be in the ceiling, as opposed to the floor for obvious reasons.
it would deffo work out cheaper to install a reverse cycle air con unit.

Hi

Yes Migo is right.

Cold air falls it doesn't rise. So it makes sense to put a loop in the ceiling not the floor.

And although the pipework is probably insulated from the concrete slab the slab is possibly colder, underneath the circuit, and would probably attract the cold to that rather than the cold work against itself and rise into the warmer room.

Anyway as Migo says its probably more cost effective putting in air con.

Good to see your thinking along new lines, like that.

Many thanks for your thoughts Migo & Bernie.

if youre using ground source or air souce heat pump for underfloor heating then most units will cool in summer if not cant see how else you could do it apart from split air con unit
