Buffer tank with internal storage< /h2>

Buffer tank without heat exchanger, but with an enameled domestic hot water tank built into the tank with insulation .
The steel container is not treated on the inside (it is not even necessary, as it will contain oxygen-free water, so it will not rust), on the outside it has a single layer of primer paint. 
In this buffer tank, you store the warm water that is also circulated in your heating system.
In this closed circuit, you can even heat the water directly with a wood-burning boiler or a water fireplace.
It can also be heated by electric also with a heating pad.
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, if the heating circuit does not work with antifreeze.
Preparation of heated bath water and is stored in the built-in inner container, which is enamelled.
