1940's 1200sq/ft semi-split ranch. Current system is a early 1980's Hydrotherm HC-145 nat gas boiler 116k net with two baseboard zones. Adding up all the baseboard there is approx 60k of radiation... previous owner was of the "bigger must be better" mindset. Have not done a Manual J yet but with new windows, attic insulation, significantly better air sealing, new stack damper, we are warm but the boiler short cycles due to lack of load.
Looking to replace the boiler with a properly sized and more efficient unit. Wondering if we should stick with atmospheric or go to a power burner setup. Had a Wayne conversion burner at parent's house for many years and it worked very well.
Currently venting into a lined chimmey. Planning to convert to a indirect HWH from the current standalone HWH when the boiler is replaced.
