Hello, I have a boiler that heats and does water for my whole house.
Radiant heat, super store on the water tank. *I have circulators on
every radiant zone, which seems fine. *My question is that there is
one circulator that comes off the supply of the boiler and feeds the
"loop" that passes by each zone and then returns to the boiler. *It is
my understanding that the zones turn on when they call for heat and
draw from the "loop" but that the circulator on the loop is always on
heating the loop to 180 degrees. *I have seen other boilers that don't
have a circulator on the supply pipe and don't have a "loop". *It
seems inefficient to me to have this always on and heating even if no
zones are asking for hot water, and this seems validated by the fact
that the room for the furnace is very warm all the time (great for
drying mittens). *I am thinking of getting this circulator wired so
that it only turns on if one of the others turn on. *Any thoughts from
anyone? *TIA, ACS

INSULATE THE PIPING IN EITHER CASE
