[AT] More radiant heat.

[Richard Strobel]

I have radiant heat in my shed..quite pricy for the amount of propane it 
uses each month ~100 rockets for a 64 x 36 shed with 3 zones..I only run one 
in the winter..keep the other two around 36 above.

  Boiler and pump(s) manifold are professional by a place down in Bozeman, 
Mt... Radiant Engineering I believe it's called..gaggle should bring it up. 
They use a puter to layout of the EXPENSIVE tubing 1/2" and 5/8's I 
believe..not one line cross on top or below another.  In the main shop, 
there are 3 runs of tubing that connect to their own manifold which in turn 
is connected to the circulating pump and a return.

  The boiler does have an accumulator er expansion tank and has it's own 
circulating pump..this is a pressurized system around 15-20 psi. An air 
remover automatic bleeder is used on the main manifold..no clue how it 
works.

  My main prob is controlling the heat..you're either to hot or too cold. 
Maybe move the thermostat closer to the floor...possibly even install a 
timer in series with the thermostat.

  But when you lay those ole bones on that warm floor..you'd think you'd 
died and went to heaven.  And now you can even wash down the floor in the 
winter and within minutes the floor is dry.

  I would guess I've got around 10k into it..boiler alone was 4,500...and 
that was 10 years ago.

  2" of blueboard,,they wanted 1", next, wire mesh/sheets with 6" 
squares....you tie the tubing to this and get the proper spacing  18" or 
12"....lay rebar on top of that and do your pour.  Recommend taking half a 
day.. taking pictures and such to document the spacing, before the 
pour...i.e.  Concrete anchors and such in the future.

  I can take pix's if anyone is interested of the boiler, plumbing and 
manifold, submanifold.

Hope this helps
