300 liter buffer tank, one coil

Buffer tank for the storage of heat generated by solid fuel boilers, solar heaters or heat pumps. It offers optimum performance of the boiler, allowing it to work at rated power even when the installation does not need all the heat produced by the boiler. The heat accumulates and is stored in the storage tank and can be used even when the boiler no longer generates heat.
