Room-to-Room ducting. . .

Your talking about heat shifting systems.

The basic principal is that you duct the latent air out of the warm room into the cooler rooms. Just ducting alone does work to a degree, but you are better off with a small fan to suck the air through.

It is either a DYI job (cutting holes for vents, laying the ducting etc) or a pro job.

My only advice is to use small ducts and only over small distances. The bigger the distance and the bigger duct the more the air cools down.

Cheers

yeah - thanks for that
but how small do you mean - ducting, 8", 10"
What kinda fans - I imagine something 'inline'
distance is not such a prob - only talking 'next rooms' - see the g'kids rooms are on the outside face of the house - facing south - so they get frozzen in the winter and boi-oh-boiling in the summer. Happens that the wood fire is central in the kitchen and so's the cooler duct.
thanks for help in anticipation

just thought - would a kitchen vent fan mounted up in the ceiling work - extract hot air at ceiling level and pump it along a duct to the kid's b'room ceilings? - noisy though. . .

I use a couple of these things, We just brought the kit from the hardware shop and whacked them in. I reckon the're good, saves me freezing my butt off in winter.
I couldn't see why you can't do it yourself with bits, as namtrak suggested the ducting in the kits is only about 200mm, and then there is a lil' fan in the middle of the run.

I don't know if it would be cheaper this way, or if you'd be better off buying a kit. The first one we got was before they were popular and we got it for a song as it had already been sitting around for a few years, the second was much dearer, can't remember exactly, about 22 sheckles comes to mind.

what's 22 shekles converted to Iraqi dinars?

thanks very much everyone
cheers

ask Abraham the moneylender

22 sheckles = $200AUD




I could admit to a typo, but I won't
