HB24 with Catalytic Module and Secondary Air

Initial testing of the catalytic combustion module with secondary combustion air supply has been completed. System functions very well without a draft inducer. This is important during periods of power failure. A hot and easy burn using one average size split log per hour produced a stove top temperature of 750°F and a heat exchanger exit temperature of 150°F. One can almost hold the stove pipe with a bare hand! Draft is still very good and there is no visible smoke. House has never before warmed up this quickly!
The HB design is based on sound principles: Complete combustion with excess air, then recover the heat. Any creosote problems are eliminated by complete combustion.
Next step is to test the optional water heating coil. We expect very positive results.

Thermal Storage

Phase change materials can be used together with water to build “hybrid” heat storage devices. A 1,200 L tank can store up to 460,000 BTU if a hybrid design is used. Heat-Booster™ has developed such a system, and it will be available in the near future. The heat storage device will be ideal for use with wood stoves equipped with Heat-Booster™ water heating coils or with Heat-Mover™ solar heat recovery systems.
