What is an Electric Tankless Hot Water Heater?
An electric tankless hot water heater is a device that can heat water without having to use a storage tank to do so. They may also be called instant hot water heaters, as the water is heated only as it is needed. In some cases, this can be a cost savings as unused heated water does not have to continually be reheated until use. The only time the heating elements work in an electric tankless hot water heater is when there is a need for them to do so.
