ABSTRACT:
A hot water probe for use with a wood or other solid fuel burning appliances (stoves, furnaces, fireplaces, etc.) to provide supplemental hot water heating whereby the use of natural gas or other non-renewable fuel can be conserved. The probe may comprise a pair of elongated, coaxial tubes of a predetermined length which extend outwardly from a header block which contains an inlet chamber sealingly coupled to the inner one of said pair of coaxial tubes and an outlet chamber sealingly coupled only to the outer one of said pair of coaxial tubes. The tubular portion of the probe is fitted through a hole formed in a wall of the appliance and it extends for a predetermined distance into the firebox at a desired level relative to the flame. The header block may be bolted or otherwise affixed to the outer side wall of the appliance. A connection is then made between a water outlet of the water heating tank and the inlet chamber of the header. Likewise, a connection is made between the outlet chamber of the header and an inlet to the water heating tank. As water circulates through the central tube and back through the outer tube of the probe, it is heated by the fire in the stove, furnace or fireplace before being returned to the water heating tank. The specification also details how plural probes may be cascaded to provide an increased heating capacity.
