Buffer tank 2-in-1

The two-in-one buffer tank is a compact device for storing and exchanging heat energy and suitable for preparing domestic hot water (DHW).

Buffer heat accumulation storage supplied from the heating device is transferred to the heating circuit providing a heating function for the central heating installation while heating up the domestic hot water at the same time. 2-in-1 buffer accumulation tanks, depending on the model, can handle up to several heating devices, thanks to the use of heating coils in the buffer without the use of hydraulic couplings or external heat exchangers.

2-in-1 tank for a heat pump – convenience and savings in one

2-in-1 storage tanks, also called 2-in-1 buffers, combine the function of a central heating buffer and a hot water tank in one device. Thanks to this:

• you store excess heat in the heating system,

• reduce energy consumption

• you shorten the waiting time for hot water,

• you save space in the boiler room.

This solution is ideal for single-family houses, apartments and small commercial facilities, especially in systems with heat pump, condensing boiler or hybrid installation.
