Hot Water Boiler

Automatic Coal-fired Boiler

Dual fuel – coal and oil boiler

Enjoy the economy of anthracite coal and the convenience of oil firing in an efficient boiler.  Easy switching from stoker to oil firing.

Automatic Coal Fired Boiler

How does it work?

Boiler gauge

High capacity steam chest, a large supply of steam or hot water.

Down-draft multi-pass steel boiler is entirely surrounded by water walls, forcing hot vapors to brush the entire inner surface o that the maximum amount of useful heat is extracted.

Sealed ash pit

Box-in-box, internally braced, welded steel construction

Low stack outlet traps heat in boiler

Heavy gauge high quality steels assures long life and utility

Vertical water baffle increases internal heat recovery action

Copper coil provides instant hot water

Available option: dual fuel coal & oil

Stoker and Boiler

Advantages to the Keystoker Boiler

The Heart of the Keystoker

A simple feed mechanism with very few moving parts, which can easily be adjusting and maintained by the average householder. Troublesome belts, sheer pins, and worn conveyors have been eliminated. A secondary combustion fan allows boiler to operate with a small fire to use less coal, eliminate overhearing, and will maintain a fire in any draft condition.

Silent electric motor

Feed mechanism is easily and quickly adjusted.

Comfortable Warmth, Keystoker winter conditions your home with clean even heat. Accurate controls and thermostat provide automatic well-regulated warmth with quick response to weather changes. Warm air water or steam heat are equally efficient with the KEYSTOKER unit.

ABUNDANT HOT WATER is available – 200 gallons or more, every hour of every day. This year round plentiful supply is made possible by the use of copper coils that heat your water in a jiffy. No hot water tank to install. Standard in all boilers.

LOW COST FUEL, KEYSTOKER is the most economical and efficient using anthracite rice or buckwheat coal. The savings on fuel bills alone will pay for your Keystoker in the course of time.

LOW INITIAL COST – check and compare! Your dealer can give you the complete price of an installed Keystoker. When you compare the cost of the Keystoker with any automatic hot water hearing unit, you'll realize how reasonable Keystoker is priced.
