Abstract
A hot water appliance is provided with an accelerated delivery system which includes a pump interconnected between hot and cold water fittings and a control system for causing the pump to circulate water from the hot water fitting into the cold water fitting when the hot water appliance is turned on. Temperature sensor is provided for causing the control system to stop the pump to prevent heated water from being circulated into the cold water fitting. In addition, a hot water demand system may incorporate a sound sensor detecting water flow in a hot water delivery line and a sound-generating element may be provided for providing a characteristic sound in response to water flow in the hot water delivery line.
