Water heating

Testing of SAFE water heating system completed

A new high efficiency wood stove from a major North American manufacturer has been equipped with a safe water heating system for testing. Results were very good and also showed what can be optimized. A low emission EPA certified wood stove, equipped with a HB24 heat reclaimer that includes a catalytic combustor and water heating coil, and the new water heating system can transfer 12 kW or 40,000 BTU/h of heat to water. Systems do not interfere with combustion process.

Water Heating with Woodstoves

Heat-Booster Energy Systems has developed safe and efficient water heating systems for woodstoves. One system uses hot air produced by the HB24 flue gas heat reclaimer, and the second system uses heat from the wood stove itself. Both systems eliminate the serious safety issues relating to exposing water in closed systems to high temperatures. Combinations of the systems can also be used. The water heating systems can be fitted to just about any woodstove.
Heat-Booster Energy Systems will seek patent protection for the system that uses heat from the wood stove itself. Licenses will be offered to wood stove manufacturers. Contact us if you are interested in being licensed for this technology.
"Do not burn without it!"

Heat Exchanger Test

A fully counter-current flow finned tube heat exchanger has now been tested in conjunction with a solar heat collector. Results were as predicted: Outgoing air is cooled almost to incoming water temperature.
The heat exchanger design has been finalized, and the system can be used with HB24 wood stove flue gas heat recovery unit as well as with attic heat recovery systems.
Test was done during a day of variable cloud cover and intermittent sunshine. This is apparent from the graph.
