Above floor radiant anyone?

Above floor radiant anyone?

PostBy: cabinover On: Thu Mar 12, 2009 10:50 am

I've been thinking and reading about how to heat my house this coming year. Bought a Chappee C-28 boiler so that part is taken care of at the moment unless that AA130 falls into my lap.

Looking at a solar site yesterday got me to thinking about a storage tank for heat. What I saw was around 500 gallons of hot water with a coil heating the water and a coil pulling heat from it. Basically a large water tank heat reservoir/exchanger.

Their thinking was along the lines of you wouldn't need to fire your boiler so often. I can see where that may have a benefit to oil, NG, or LP but is there really a benefit with coal? I mean it heats so evenly. I guess if it's a warm day you could store that heat.

I'm going to build on this post but I'll leave it like this to see what everyone has to say.

The site, if anyone is interested, is http://www.slatevalleyboilers.com under Heat Storage Tanks.

If it's not OK to give this info out please remove it and I apologize.

Save your space and money, with a coal boiler there is no need for a heat storage system. The controls on the boiler will control it's temperature and the boiler stores a significant amount of heat. These systems are mostly used with wood where the fire must be maintained at high temps for efficiency and the fact that they can run out of fuel quickly if unattended.

Yaaa, What Coaledsweat said. Storage is for heat that's intermittent, like solar (no sun at night) or wood ( burn it hot & fast & let it go out or nearly so).

Well that's cleared up now. Thank you.

On to the next part of this baby that has to do with radiant. While looking around I see some folks doing above floor radiant. The pipe is laid down between basically what are joist extensions above your current subfloor. Sand poured to fill the remaining gap and another floor laid directly over it. The only benefit I've seen for this is the pex used is 1/2" rather than the 7/8" that one radiant company suggests under the floor. The drawback are more cost for flooring.

If one were to use 1/2" under the floor, with foil and insulation, would this cause an issue with your circulator? Being a smaller ID it would raise your head correct?

I need to go about 150' to my house before it hits a manifold. I was told one of the best ways to keep everything happy is through injection. If I had a constant loop from boiler to house and just pulled my radiant and hot water from that does that sound feasible? I'm figuring about 4 loops, 5 at the most. Around 900' of radiant total. One zone.

I'll have a dump set up in the garage as well to take the rest of the heat.

The original plan of using my FHA just isn't doing it for me. I hate that fan noise so unless I could find a slower fan or put an air handler under the house and use the underside for a cold air return I'm not particularly fond of the idea.

What do you guys think? There's a million ways to get this done I'm finding.

I'd staple the tubing up from under. If it's on top you need to do something with every door and now the first step of any stairs are high or low.

I'd also go from the bottom.....KISS (keep it simple stupid...no offense). I just did an install yesterday of what you are talking about doing. I tried to talk them out of it......... but it is a pex array over a 3/4 floor, 1 1/2" sleepers and another 3/4" plywood floor. No access...ever, and that bothers any mechanical person. Don't forget that you must temper your water in the radiant piping, you cannot circulate 180 degree water in that type of installation. We all talk about what the heck will happen ten years from now when some spirited flat-tlander storms into town and thinks he or she is going to remodel some of these 'purpose built' homes. OMG! What is cutting edge today will be the Edsel of tomorrow.
On this forum we have folks just discovering that coal can actually be used to heat a dwelling!!!! That was big news back in the 1820's, but in 2009, we should look over our shoulders to see some pretty darned bright folks were walking the planet before we got here and perhaps we should look backward before we jump into the gene pool.

You cannot engineer out the dumb asses in our world. Your point is well taken. You can easily see why freddie and I don't want you to go that way. Have you been reading too many "self help" radiant articles? :o :roll: :lol: :lol:

Just think about the issues with floor coverings...door jambs, doors...height loss. I guess we should just go back to dirt floors and sod roofs...horse and buggy, log cabins....

My reply was supposed to be humorous it just didn't come across that way. I was thinking just what you were saying about no access to the pex in an above floor installation. I can just picture the next owner installing new flooring and driving nails through it, what a mess that would be.

I agree, you cannot engineer out the dumb asses. I try but I'm just a mechanic:D
