The WARMTEC OptiShower electric water heater is a device that heats tap water in a flow system. It is the most effective way to get hot water in a washbasin or sink using the 11kW or optional shower at the 14kW unit. Tankless water heaters are the most modern group of heating devices that provide domestic hot water (DHW) immediately, whenever it is needed. The water is not preheated but heated directly as it flows through a heater installed near the water intake point. Thanks to this, it does not use energy to maintain the water temperature, as is the case with capacitive heaters, which save up to 85% of energy. The WARMTEC OptiShower heater has a modern, patented heat exchanger, thanks to which scale deposition is wholly eliminated. The water flow channel is completely separated from The live parts ensure high durability and 100% safety of use.
