Folks
I'm trying to understand the boiler outdoor reset curve and it's workings... I'm specifically curious about the circulator pumps running and the length of time it takes to heat a home. Heres my question in kind of the form of an example:
The outdoor reset curve is set so that at 65 degrees F outdoor the boilers output is at 120 degrees F. The inside of the house is 65 (and outside) and the call for heat is set to 75. The house heats up eventually so heres my question... I feel like it will take a long time to heat the house since the radiators (fintube) are only at 120. Without the reset, the boiler would throw out 180 to the radiators and I would think it would heat the house faster. The problem with taking longer to heat the house at 120 vs 180 I feel is the circulators would run longer using more electricity. I'm thinking once the system is stable and it gets colder outside the circulators won't run that much.
I hope you understand my question, I just want to learn more and understand this...
