Radiant Ceiling?

[Deleted User]

Easily. I think ceilings and walls are one of THE most overlooked radiant potentials there is. Quick notes;

Use sleepers running at a right angle to the roof/ceiling trusses. Use aluminum heat transmission plates and mud if necessary. The more mass, the merrier. I'm waiting for them to improve the phase change panels and tie them into solar. That'll be HOT!!

Don't forget the importance of insulation at the radiant panel.

Utilize wall mounted non electric TRV's and 4 way reversing valves if necessary. Spread the heat evenly...

Most calcs dictate that the 4 foot exterior perimeter need be done. I double that space. It allows for more table to spread the heat upon, and allows it to work better at a lower temperature. Lower temps = lower btu demand = less pollution emmitted keeping the occupants warm. Think extremely green!

Easy way out, get ahold of a manufacturer with experience, like Wirsbo, and DO IT. Just make sure it gets done by a professional, because it can be expensive going back in to do repairs. As is usually the case, you have one good shot at getting it done right and inexpensively...Take your pick.

I have never had the oppertunity to see or install one of these animals, but I was curious about how one does this type of install? Where do the tubes get attached? I assume you MUST use a glycol mix? Where do you locate the manifolds?

Just food for thought!

Thanks again, Jamie

my experience

The worst part of my install was that the floor joists were NOT all the same dimensions. The ends appeared to have been trimmed with an ax (No kidding) where they lay on the sill plate so that the tops would form a level floor surface.

Yes, my 100 year old 2x8 floor joists varied from about 7 3/4" to 8 3/4". I had to snap a lot of lines, and do some very back-breaking and somewhat dangerous overhead skill saw work to get to where my perpendicular sleepers screwed to something close to flat.

After that, things were easy, it's quick responding, and works great. Having said that, it's NOT the same as radiant floor. Kevin
PS, as has been noted here before, these can, and mine does, make a slight ticking noise at times that sounds for all the world like water dripping on sheetrock.

Mine is NOT on outdoor reset and continuous flow which would probobly correct most if not all of that. However by some strange reason, I have come to enjoy the sound. I know it's crazy, but some people come to enjoy the creaky sounds of their old houses. Part of the home's character I guess.
