In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Hi all, hoping to get some help on sizing a new gas boiler for my house. My current system is a Utica bc4t oil fired boiler installed in 2008. Sized at 196,000 btu input and 165000 btu output. DHW is also provided through the boiler. The boiler says 143000 water heating capacity. A little background on the house. Built approximately 1930-1935, I live in one half of a double home. The home is approximately 1350 square feet of heated living area, along with an unheated basement at approximately 480 square feet. Living space is heated by fin tube baseboard.
The home is not well insulated. No insulation in the walls, most of the windows are replacement double glazed. All other windows are what I believe to be original to the house, single pane with storm windows. Wall cavities above the sill plate are stuffed with fiberglass bats.
The system is split into two loops both connected by one pipe to the boiler output. 1 loop is for the first floor, and the second loop is for the 2nd floor and finished attic. First floor loop has approximately 55 feet of baseboard, and the second and third floor loop has ~ 67 feet.
I'm having trouble getting contractors to give me estimates. I've had three in the house in the past 2 months and only has sent me a proposal which is way out of price range for a utica svb4 and a 40 gal indirect tank. The other 2 I have called multiple times since they were here and I have not had any luck getting them to send me a proposal. I don't believe that any of them have done a heat loss calc on my home.
I've used the slantfin heat loss calculator myself and have come up with about 77k btu/hr, but that seems quite high for the size home compared to some posts I've been reading on here over the past 2 months. I'm not sure about some of the terms and some of the construction of my home, so I can't be completely accurate myself.
Any help/advice/comments would be greatly appreciated as I'd like to get a new system installed before the winter and take advantage of the installation rebate that the gas company is offering.
Pictures of my current setup/piping and any other information on the home that I can give I will be more than happy to provide.
Thanks in advance,
