DEFRO 200L buffer tank is responsible for collecting, storing and transferring excess hot heating water from various heat sources, such as pellet boilers, eco-pea boilers, back-fed boilers or heat pumps. The buffer is a safety feature of the central heating system. It takes over the difference between the heat output of the heating devices and the power given to the heating system. Thanks to the stubs mounted on the side, it can be easily connected together with heating devices manufactured by DEFRO. Thermal insulation of the buffers is formed by a layer of polystyrene foam permanently attached to the walls of the tank. The thermal insulation cover is made of plastic. Our buffers have a high energy efficiency class.
