The instant invention (heat recovery vat, reference Provisional Patent U.S. 62/762,041 “boiler pot”) relates to heating a living space with a wood stove. Hydronic heating systems recirculate a heat exchange fluid through a heated first heat exchanger to heat the heat exchange fluid and then through a second heat exchanger (a “radiator”) located in a living space to heat the living space. A plurality of living spaces (such as different bedrooms and a living room) are usually heated as individually controlled zones. It is not advisable to place the first heat exchanger of a hydronic heating system inside a wood stove. Heating living spaces that are remote from a wood stove from heat generated by the woodstove by natural convection of air heated by the wood stove is difficult or nearly impossible in the case of a closed bedroom. It would be an advance in this art if a hydronic heating system were discovered that could be used with a wood stove.
The instant invention is the discovery of a hydronic heating system for use with a wood stove. More specifically, the instant invention (heat recovery vat) is a hydronic heating system water heater, comprising: a pot or vat, an inlet pipe and an outlet pipe, the pot or vat having a bottom, sides and an open top, the inlet pipe positioned through and sealed to the side of the pot or vat, the outlet pipe positioned through and sealed to the side of the pot or vat so that when the pot/vat contains water and the pot/vat is placed on a hot wood stove, the water in the pot/vat is heated by the hot wood stove so that the hot water can be flowed from the pot/vat through the outlet pipe through a heat exchanger and then back into the pot or vat by way of the inlet pipe. In another embodiment, the heat recovery vat is a method for heating a first living space from heat generated by a wood stove located in a second living space by the steps of: heating an open container of water on a hot wood stove in a second living space to produce hot water; flowing the hot water through a radiator and then back to the open container, the radiator located in a first living space to heat the first living space. In yet another embodiment, the heat recovery vat is a method for heating a first living space from heat generated by a wood stove located in a second living space by the steps of: heating an open container of water on a hot wood stove in a second living space to produce hot water; flowing the hot water through a heat exchanger and then back to the open container, exchanging heat from the heat exchanger to a recirculated fluid flowed through a radiator to heat the first living space.
