One way to save on domestic hot water bills is to use (DEMAND TYPE WATER HEATER). A conventional hot water system heats water in a tank to a specified temperature. As heat is lost from the tank, the water is reheated until it reaches the specified temperature again. For most of the day the water in the tank is not used, but it loses heat continually. DEMAND WATER HEATERS Eliminate this problem by heating water only as hot water is drawn. |

IT IS EASY TO SEE WHY CONVENTIONAL WATER HEATERS ARE NO LONGER ECONOMICAL OR PRACTICAL... They consume electricity to heat water that is not being used, a process that repeats itself over and over even though no hot water is needed.
