Abstract
The present invention is directed to a water heater that sustains energy during the standby mode so that it can power energy saving devices while e minimizing energy loss and controlling the stored water temperature. The present invention may include an outer casing, an insulated tank containing flue tubes, a combustion chamber, a burner rack containing a pilot and thermopile assembly, a flue collector, a damper and a draft diverter. These components are preferrably arranged to enable heat from the main burners to be transferred in an efficient manner to the water when needed and heat loss from the water to be minimized when the main burners are not fired. This may be accomplished without the use of external electric power, and the energy producing and heat transferring components of the water heater are optimally balanced, resulting in a sustained energy level that minimizes heat loss, prevents unwanted increases in water temperature, and enables the use of a damper without external electrical power.
