Cooling-heating buffer storage

The cooling-heating buffer tank is suitable for storing both cold and hot water and can be connected to a heat pump.
In this buffer tank, you store the liquid that circulates in the heating system in winter and in the cooling system in summer.
Cold-hot water storage buffer tank is suitable for storing cold and hot water produced by a boiler, heat pump or pellet boiler. 
The water in the closed circuit is heated directly
with the boiler, with a fireplace or heat pump.
It can also be heated with an electric heating pad.
It is steel container is not treated on the inside (it doesn't need to be!),
on the outside, it has a single-layer primer paint and is covered with excellent heat-insulating polyurethane hard foam.

The VOLANO TERMICO PDC tanks connected to the heating system keep and store the thermal energy produced for cooling and heating that is not directly used, and then fed into the system according to the usage needs through a circulation pump. The use of cooling-heating buffers reduces the number of switching of the cooling-heating equipment, and also reduces the loads that can be caused by circuits with different temperatures.

If you want to store domestic hot water (bath water) in the tank, choose a hot water indirect storage, boiler!
