Burner Conversion Question - Weil-McLain P-SG0-3
We're closing on a home in MA in several weeks that has a 5 year old Weil-McLain P-SG0-3. Heating system is steam. Boiler has HW coil on it.
The oil tank is at end of life and there is gas already in the house,
so we're considering converting the boiler to natural gas rather than
replacing the oil tank. We'd prefer to fix this before the heating
We're just trying to get through our first heating season in the new
home before making any huge expenditures but we don't want to roll the
dice on the oil tank.
Based on reading here (great resources!) and other places, I thought this system would be a prime candidate for a burner only conversion with a cleaned chimney. However, several plumbers with experience on steam systems have told me this would be throwing my money away and I should just get a brand new boiler plus a HW heater.
They've given various reasons including the following: 1) Gas won't be able to keep up with the tankless HW coil on the burner because it does not burn as hot as oil. Coil will also wear out faster due burner being gas rather than oil. 2) If the boiler has been running on oil, converting the burner to gas is somehow bad for the boiler (not the chimney, the boiler itself) 3) We'll be wasting a lot of gas if we only convert the burner 4) The rebates from the gas company, which I've already priced out and still seem more than we want to spend. All of their gas boilers require a separate purchase of a HW heater.
Is there any reason (safety or cost) that we could not do a burner conversion on the boiler now, keep the tankless on the boiler with a converted gas burner, and add a HW heater in later years?
