Tankless Water HeatersTankless Water Heater Repair Charleston SC

On-demand, tankless, or rapid water heaters heat water instantaneously when it is asked for, and so there is no need for a storage tank. On-demand water heaters are activated by the flow of water. When there is need for hot water, a fuel valve opens, stiring up the burner. Cold water gets in one side of a coil of copper pipe, which then twists through a heat exchanger that is surrounded by flame, and hot water exits the various other side of the heat exchanger.

The efficiency of an on-demand water heater is based on the heat transfer effectiveness of the heat exchanger and is 75 to 90 percent effective. One prospective problem is pressure drop throughout the heat exchanger which can produce lower flows when more then one source of hot water is used.
