Abstract

A system and a method is described for remotely controlling gas consumption by a power vented gas-fired water heater to reduce consumption of gas by a consumer connected to a gas distribution bank network of a gas provider during overload periods where gas demand is at a peak. The system comprises a consumer controller in communication with the gas provider whereby the controller can operate a modulating gas control valve either directly or through the control of the fan speed of a power vented blower to reduce the supply of gas to the burner of the gas-fired water heater when asked by the provider to do so. Temperature sensors are associated with the water holding tank of the gas-fired water heater to feed water temperature signals to a computer of the controller whereby to enable the controller to execute informed corrective action for the reduction in gas consumption by regulating the gas control valve to reduce the supply of gas to the burner of the water heater.
