Buffer container

Production time: 1-3 months from order.

Buffer tank with 2 heat exchangers, connection points rotated by 90 degrees, so it can be easily installed in a corner, where the connectors are also easily accessible.
Thermal insulation can be added as an option below the price!
In this in a buffer tank, you store the water that circulates in your heating system and that is heated by the boiler or open fireplace.
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 it circulates antifreeze. ;">It can be connected to the 2nd upper heat exchanger, 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. is used to heat half the volume of the container.

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 or boiler with a heat exchanger, they are enameled or stainless, so the drinking water in them remains clean!< /span>
