Abstract
A heat retaining device comprising a plurality of heat retaining elements which can be positioned on the burner of a hot water heater. While the burner is ignited they collect and store heat from the burner which ordinarily might be wasted. After the burner is de-energized the heat that they release keeps the water in the hot water heater warm so that the intervals between energization of the burner are increased and fuel is saved thereby.
