Boilers: Steaming Small
This high efficiency oil-fired steam boiler has an average AFUE (annual fuel utilization) rating of 85% or more and is offered in eight sizes ranging from 75,000 to 275,000 BTUs.
It can be vented vertically or horizontally with a vent on back or top. The hinged burner door swings out of the way for easy inspection of the cast-iron boiler. An optional extra is the high capacity tankless heater which provides hot water year round, even when steam heat is not being produced.
The boiler carries a ten-year limited warranty.
