[Greenbuilding] Hot Water Return Revisited WAS Windows

[Gennaro Brooks-Church]

I spoke to an HVAC person over the weekend who is in my NaSBAP class
and he claims he has run the numbers on a hot water return system
where once the return water reaches a set temperature the pump cycles
down to a slow trickle. He claims the electricity at that level is so
small you could put your tongue to it and the heat lost through the
well insulated water pipes is negligible.
I'm not sure about the heat lost through the pipes. But the
electricity being low does sound right.
