Abstract
A heating system with a hot water coil is provided with a variable speed blower whose speed is regulated in response to a sensed load in the system. Heat can therefore be added to the hot water by way of a simple burner system, with the required control being effected by selectively varying the amount of heat that is removed from the hot water by controlling the fan speed. When applied to a zone controlled system, the need for a bypass duct is obviated.
