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.  AVAILABLE DUAL FUEL with OPTIONAL OIL BURNER

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.
