Submetering hydrocarbon fueled water heaters with energy manager systems

摘要: A hydrocarbon-fueled hot water heater for supplying includes a cold inlet, outlet, selectively activatable burner applying heat to volume of between the inlet and sensor sensing activation at least one burner, communication interface communicating data corresponding processor configured multiply amount time is activated by known value flow rate estimate an fuel consumed heater. Other devices methods submetering hydrocarbon fueled heaters are also included.
