Commercial heating needs typically require a boiler or furnace that outputs a higher number of BTUs per hour than systems used for residences. Alternate Heating Systems has boilers that produce up to 1,000,000 BTUs per hour. Below are the models from our product families that particularly meet the needs of commercial operations.
Note that any of our boilers, including models with smaller BTU/hour output as well as our Outdoor Wood Furnaces and Outdoor Coal Boilers, could be used to heat a commercial space so long as they are sized appropriately for the space being heated.
