Buffer tanks SUNSYSTEM SPBM-R2 with two coils

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.

Buffer tank design allows heat distribution of layers through integrated dividing plate and distribution plate (water stratification unit).
