Availability: In stock

The buffer tanks of series PR of the company SUNSYSTEM used for improving the performance and efficiency of heating, through the production and storage of hot water, which is used in the central space heating system. These specific buffer tanks allow the use of up to 2 external heat sources and optional kit for electric heating with nominal power  3kW, 4.5kW, 6kW or 7.5kW.

Accumulates the heat generated by boiler; recommended for each space-heating system.  Ensures optimum operating mode of biomass boiler, permitting its functioning at nominal power output even when the heating system does not need all the heat energy produced thereby.
Produced heat is accumulated and stored inside the buffer tank and can be used even when the boiler itself has cooled down.
