Welcome to Keystoker

Quality Materials, Workmanship and Service
Only The Sun Does It Better!

Over 60 years experience in producing anthracite coal heating equipment to provide an economical solution to the high cost of today's energy.

A remote Honeywell thermostat makes your stove, furnace, or boiler completely automatic.

Our boilers are built with heavy gauge high quality American made steel and are equipped with a copper coil that will produce 5 gallons of hot water every minute. The Keystoker warm air furnace is built to deliver maximum heat. The downdraft heat exchanger increases heating surface permitting direct circulation of every thermal unit into the warm air leader pipes for rapid distribution.

Our stoker stoves speak for themselves. Tested at 88% and 90% efficient with our patented flat grate stoker design and patented built in heat exchanger you can now get the high efficiency you are looking for in a coal stove.

Bottom line: more heat, fewer dollars.

Keystoker --a leader in the industry SINCE 1946.
