Got into the 60's today & the zones stopped calling for heat -- I saw 237* on the boilers aquastat!!
I've got just over 20 psi in the system, so I'm not worried about boiling. The stove wasn't even cranking either!
The indirect boiler called for heat just after I checked the boiler temp & brought it down to 212*.
Last night, I left the TV room zone on & turned on the 2nd floor zone -- the whole house was warmer than it had ever been! (except in July/August
) I can't believe it kept the temp up around 170* with both zones open! This is GOOOOD!
The real test will be in the cold weather. This setup will probably take all day to warm up a cold house, but I think that once everything is up to temp, it shouldn't have a problem maintaining heat -- especially if I really crank the stove up.
It got down to 40* last night & my house never cooled below 71* ! The house got up to 77* when it warmed up outside -- with a VERY low fire. This Mark III throws the heat out! It should, seeing that I can almost fit an entire 50lb bag in one shot when first starting up!
I'll post the results once the temps drop & stay low, which will be in about a month.
Time for bed........here comes Monday.........
