I'm getting quotes to convert my 8 year old, W-M SGO Gold 7 to gas. I have steam radiators. 20 radiators are spread throughout our 2 1/2 family house which is about 4000 sq. ft.
I got one quote for a Carlin conversion kit which I can live with. Another company is telling me that my efficiency will "go down the tubes" if I don't get a new gas boiler. They are saying that the W-M "was not designed for gas" and that "in their experience" conversion kits are almost never worth it.
I guess my question is: How concerned should we be about a loss of efficiency? We are currently paying about $4000 a year for oil. The first conversion company estimates that we can reduce that to about $2500 a year with the conversion kit?
A new furnance would be almost twice as much as a conversion kit.
Thanks for any information. Much appreciated.
