First, my reading on heated floors (in books
30 years old) is that they will not be able to supply the
entire heat load of a greenhouse.
My experience here is in a central boiler which
heated water that was pumped through
3 buildings, heated with fin pipe vs radient slab.(
I built and ran the entire system, with the only
pro help being the welder I hired the do the boiler
tubes) I trust the cold return water would
be of someof the
same causes; mostly lack of proper circulation. The wad of cool water that is in
the
pipe when heat is called for should pass quickly
into the boiler, and the difference in temp
between supply and return should be
slight.
Perhaps we can investigate why this did not happen.
Hopefully others will join in!
How were you heating the water? How much water does
it hold? What size burner?
What do you have for pumps in the heat loops?
Do you have a widget on each line to let the air out?
Did you open each line at the return end and pump
out several gallons of water to make sure you had
the lines purged of air and that there was proper
circulation.
