Question

Boiler Troubles *I Need Help Please*


Hi, Purchased a 2000sqft house with 10 radiators. The house originally had a 150,000 Btu boiler. I recent allowed the contractor who renovated the house to have a new boiler installed the guy changed the boiler to a 95000 BTU boiler. I have not rented out the house yet and the Thermostat has been set constantly on 51 degrees the bill at that house is $500.00 for this month ONLY for 22 . For only 10 days last month the bill was $200.00 for gas service.. Does any one have any ideas of Why this bill is sooooo high??? Is the boiler to small and being over worked? The Gas man has checked there are no leaks.
I have myself since had 3 Plumbers check the house they Estimate the boiler size at 105,000-125,000 Btu’s. What should I do?? How should I approach this situation. Please help!

Do a heat loss/gain calc, and find out how much heat it really needs.

Problem could be several things.

What temp is the thermostat set to.
What temp is the boiler set to.
What circulator is being used.
Is it a monoflo system.
Is the boiler able to maintain thermostat set temp.
Have you checked with the gas company, to see how the gas bills were for the previous owners.

You are very deep and have WAyyyyyyy more knowledge then me in this area. I only ubnderstood a couple of the things that you asked me. I have had the theromstat set on Only 51 degrees that is why I am so concerned about how high the bill is. The gas company feels that the bill is high for only having the thermostat set at 51 degrees. Yes the bolier can maintain and shut down at the 51 degree temperature, but I do not know how long it take for it to reach it. I do not live there yet. !

Thanks for your great insight!

Is this a steam or water system? It could be a piping issue or water temp issue. If you have glass in the windows the boiler size is not over sized. 2000 sq ft should not take over 95,000 btu's unless you live in Fairbanks Alaska with no insulation.
How did he size the boiler. The only way is a heat loss.
Do you have pictures.
Also bear in mind an empty house always uses more fuel than a lived in home and our winter (thanks to global warming) is colder than average, will add to the fuel usage.

Hi, I thought about the fact that the house being empty as maybe part of the problem, but there are Drape and blinds up at the windows helping retain some heat. The thermostat is only set on 51 though a $500.00 bill is a lot for those circumstances. I suppose I will measure all rooms and radiators and call the plumbing supply heat specialist tomorrow. Hopely he is not to hung over from the STEELERS VICTORY later today after all we are in Pittsburgh. Thanks and enjoy the super bowl!
