Abstract:
A water heater, particularly but not exclusively for domestic use, is herein described and having removably secured thereto an external modulating gas power burner to heat the water in a separate tank portion. The two are easily separable from one another for service, repair or interchange. The hot water or a mixture thereof from the burner is circulated in a heat exchanger to transfer the heat to the tank water circulated from the water tank through the heat exchanger.
