Abstract
A heating system includes a water heating solid fuel stove operated in conjunction with a gas or oil fired hot water furnace. The two are connected in parallel and furnish heat to at least one heating zone and domestic hot water. In a first embodiment, a circulator pump is coupled to receive zone return fluid at its inlet and pump fluid from its outlet to the fluid fuel fired and solid fuel fired boilers. A first water valve is coupled between the circulator outlet and the solid fuel fired boiler, and a second water valve is coupled between the circulator inlet and the solid fuel fired boiler. In a second embodiment, separate circulator pumps are coupled in series with each of the fluid fuel fired and solid fuel fired boilers.
