Accumulating the heat generated by boiler, the buffer tank BURNiT PR2 with two coils is 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.
