Buffer tank with internal storage

Buffer tank without a heat exchanger, but with an enameled domestic hot water tank built into the tank with insulation.
The inside of the steel container is not treated (it is not necessary, since it will contain oxygen-free water, so it will not rust), the outside is painted with a single layer of primer.
In this buffer tank, you store the warm water that is also circulated in your heating system.
In this the water in the closed circuit can be heated directly with a wood-burning boiler or open-air fireplace.
It can also be heated with an electric heating pad also.
You can only connect a solar collector to the buffer tanks with an internal (possibly external) heat exchanger, because antifreeze circulates in them, therefore a lower heat exchanger tank is required. A heat pump can be connected directly to it, if the heating circuit does not work with antifreeze.
Heated bath water is prepared and stored in the built-in internal tank, which is enamelled.< /p>
