If you want to cut about ten to twenty percent from your water heating bill and still want to use electricity as the energy source then consider installing an electric tankless water heater. The old tank storage water heater systems store their hot water in a tank and maintain the high temperature water by thermostatically heating the water constantly. And, since water heating accounts for at least fourteen percent in the average U.S. house energy useage, then this can be a significant drain on the household budget.
Electric tankless water heaters supply copious amounts of hot water to your home at a predetermined temperature on demand without needing a storage vessel, in doing so it eliminates standby losses. Electric tankless water heaters can be used to meet all hot water needs of the American family with less running costs.
Tankless water heaters generally come in differing forms of energy consumption i.e. electric, gas, or propane heating devices are the most common. When it is running, the heater provides a never ending supply of hot water. As a rule gas tankless water heaters can meet higher capacity requirements but if electricity is all that is available then it is unlikely you would be finding yourself not meeting your needs, however if the requirements are beyond the largest electic tankless water heater then you can always install two systems.
Electric tankless water heaters chew through high levels of electricity but still are better overall than tank type water heaters in the long run. Let´s face it, we don´t use our hot water 24 - 7 do we, so therin lies the savings as tank type systems are constantly heating the water to the thermostat set point. Electric tankless water heaters typically have a capacity closer to 3 gallons per minute.
