I just went through the pain (and expense) of a boiler replacement.
Located in Langley, BC.
Some background here: http://www.smallrvs.ca/?p=1345
After doing more research elsewhere and from what I read here I do seem to have oversized.
My own fault. Should'a listened to the installer.
Comes from the "bigger is better" thinking process acquired over the years.
Seems that thought process doesn't apply here
Our old boiler was 135k BTU's running at 160 degrees.
Piping in boiler room (closet) is copper but distribution to baseboard fins is Poly B.
House is baseboard fins, 2 floors, and a garage has infloor heating.
No Poly B in the concrete, it was done later.
Best I can tell, no plastic fittings with Poly B but of course I can't see all of them.
240E replaces boiler and hot water tank.
We have the Outdoor Reset Control.
B. is set to 1
I would like to limit Supply temp to 160 so as to maintain max temps we used to have, mainly for the benefit of the Poly B.
Currently boiler temps are running 140-150. During the night we dip into mid 20's.
I did see 161 on one check but only once, early morning.
I do like it warm so the thermostats are set at 71 degrees 24/7. House is occupied 24/7.
4 baseboard zones + garage zone with mixer valve. 1 baseboard zone is on second floor.
Now for the question... Does the N. setting override the default settings of B. 1?
Hoping it does, I have set N. to 160.
If it doesn't override the B. 1 I'm guessing I have to do a custom setting for B?
