Storage tanks for hot water preparation, suitable for many types of heating systems including heat pumps.
Depending on the temperature of the heating water that is accumulated in the tank, the connection with the boiler allows DHW heating in the inner reservoir to the required temperature. On the other hand, connecting to solar collectors or a heat pump will only preheat DHW, and it will be necessary to include an additional (for example, electric) water heater, which will heat the water to the desired temperature. Electric heating, provided by either the TJ 6/4" electric heating unit or the TPK heating flange, can be installed into the storage tank.
