The task of buffer heaters, as in the case of boiler heaters, is to heat the water in the tank. The heater is connected to the power supply and placed in heat accumulators equipped with a connector. It is worth noting that the higher the power of the heater, the faster the water is heated, but also the higher the energy consumption.
The heaters are available with or without a thermostat. Thanks to the thermostat, the temperature suitable for the user is maintained. The use of electricity is also reduced.
