Abstract:
A standard hot water heating system is improved by adding a high-low temperature limit controlled auxiliary boiler. The auxiliary boiler is smaller than the main boiler and the burner for the auxiliary boiler is, of course, smaller than the burner for the main boiler and uses less fuel. In a particular embodiment, the auxiliary boiler continuously maintains the temperature in both boilers within the range of about 170. degree. -212. degree. F. As a result of the constantly maintained elevated water temperature in the main boiler, less time is required for the main boiler burner to heat up the system upon the demand of a room thermostat.
