We have an 8 year old Burnham V8 series boiler. Should and can we convert it to natural gas from oil? I have been reading others have done it. It is a 87% efficient unit heating our baseboards and hot water. The recommendations I have had so far from the quotes thus far was a Carlin burner swap out, existing is bekket, line the chimney and put a new highly efficient gas hot water heater separately. Anyone done this conversion for this unit? Experiences?
