A person named Nahsani recently posted the following on the alt.hvac newsgroup:
"My two-year old Slantf "My old boiler was ancient - 50 year old, big. Then it puffed back and wrecked my house. Anyway, I only replaced the boiler and the pipes leading into it. It used to work fine (the new one). Although my ex-boiler guy insisted that the on and off operation is normal, I really think it's important. I would say the btu rating is less for the new boiler, but I don't know and I don't know what the old one was. I've lived here for 13 years and it is a tiny house - 810 sq.ft. one floor. Mostly new windows and insulation. The whole house is cold and I have no idea about the piping. The weird thing is that it got my house up to 70 yesterday, for the first time in a long while. Today, it won't get going."
I decided to also post it here in case anyone here has and ideas or suggestions.
