the house I bought has a steam boiler from 1984, and its super rusted on the bottom, I think its time to replace it.

Lol, reducing temp is not equal to increase in efficiency
@dwaynesykes6942 ай бұрын
It does because lower water temp out of the boiler also means lower flue gas temperature. The residual energy in flue gases is wasted. Running at lower water temps is critical to the efficiency of condensing boilers. For conventional boilers, it helps but the difference between 140F (minimum to prevent flue gas condensation, which will rapidly corrode and ruin a non-condensing boiler) and 180F (typical max) is near negligible. tl;dr: reducing [boiler] temp equals less heat blown out the smoke stack

It is too often heard that “your boiler size is too big, “ this should be told to the plumbers, not the house owners. The plumbers want to make money so, they always install over capacity of boiler to their customers. The plumber treat the homeowner as an idiot

How can we do a beat loss test if the boiler is broken? I just bought a home, boiler was working and the next day after closing the boiler is dead... it was a 175k BTU and I got an estimate from a plumber about fixing it. He recommended a new 200k BTU.

You don't need a bigger boiler than the one that was already in the house. A Manual J heat load analysis is based on the size of the house, the size of the windows, and a blower door test to determine the home's air changes per hour. You don't need the boiler to be working to do those calculations.

Very informative vid, thanks for posting it. Contractors seem to just want to replace your unit with what you had. I have a 35 year old unit, the house since has had energy efficient windows, siding installed. The boiler is also in a heated space in a lower level closet (high ranch). The old boiler seemed too much for the size of the house and based on fin tube feet in the house it is. Would love to do the heat gain loss calculation but seems difficult.

Your newer boiler is likely to be more efficient than your older boiler. You should take that into account when sizing your boiler. One way to get a handle on the proper size for your new boiler would be to look at how much fuel you burned during the coldest month this last year - then convert that fuel use into average Btu / hour. If you sized your boiler for double that number, your new boiler would be running 50% of the time during the coldest month of the year.

Mark Sandeen Appreciate the suggestion and will look at that, is there a way to differentiate the gas being used for the water heater ? Regarding replacements capacity right now this is what I’m thinking: I am trying to size a replacement boiler for my house it is in the lower Hudson Valley in NY. (20 miles outside NYC) It’s a bi level with 2518 heated square feet I have a 114.5’ of heated fin tube and a Beacon Morris kick panel blower heater that supposedly puts out 12500 BTU on high based on this my demand is about 81,200 BTU. I imagine I would base my sizing on the DOE output number posted by the manufacturer factoring in efficiency of the unit. My current leaking Utica is 150000 BTU input, 124,000 DOE output it lasted about 35 years. Sounds too big, house was built in 1963, vinyl sided double insulated windows now. Boiler is in lower level heated space in a closet. I am going to replace based on my demand using DOE output as the gauge of power, I don’t want to go way over based on the calculation. Thanks again

I have a problem trying to figure boiler size because I did a lot of insulation from 4” to the footing on a full basement to double stud walls with 7” of closed cell foam. I’m going to have a bunch of zones for garage and it’s a duplex. I did most of the work except concrete and some roofing myself. It’s been a long road but we live in one half and I’m heating the other as it’s ready for drywall. We have been using oil with two Toyo Laser 30s burning about 500 gallons a winter. Natural gas is only a little ways and $10 grand up the road and that’s just to the driveway.
