Got down to 29° here last night - coldest night of the season. Couldn't have timed this better!
Boiler water was 206°, DHW at 150°, and both the leaky ass TV room zone, and rest of the first floor were 71.6°!! After 13 hours run time, it looks like I used a bag ... maybe a bag and a half so far, and that's including heating up 41 gallons of DHW from 70° to 150°, 30+ gallons of boiler water, and 2 zones. Certainly can't complain about any of that!
Just have some minor tweaks to make. Need to wire in the circulator to a switch instead of sticking wires into an extension cord ....
... and hook up the aquastat I just bought from Rob R..
Thanks to all you guys for your help - you know who you are!! YOU GUYS ROCK!! :punk:
