Buffer tank with 2 heat exchangers

You can connect the solar collector to the lower heat exchanger.
It is necessary to connect the solar collector system with a heat exchanger , because antifreeze circulates in it.

The 2nd upper heat exchanger can be connected, e.g. the underfloor heating or another heating unit.
Each container has a connection in which an electric heating insert can be installed (from 2kW to 9kW), and approx. it is used to heat half the volume of the storage tank.
If you want to heat the domestic hot water itself, i.e. the hot water flowing from the tap in the tank, choose an indirect storage tank with a heat exchanger, a boiler, those they are enameled or stainless, so the drinking water in them remains clean!
