Description
DEFRO GAMMA is a boiler installed in central heating systems. This boiler has class 5 emission according to PN EN 303-5:2012 standard and an ECODESIGN Certificate (ecodesign). Possession of this certificate and class 5 emission allows you to apply for a subsidy for its purchase and installation. During the production process, a pellet burner was used which has a self-cleaning function and an automatic fuel ignition system as standard. A spacious fuel tank allows operation without refueling with pellets for several days, which is contributed to by the use of ceramic catalysts that stabilize the combustion process. The heat exchanger was made of high-grade boiler steel. The shape of the heat exchanger ensures high efficiency and easy cleaning. Thanks to its innovative structure, it is equipped with the ability to move the fuel tank to the other side. It also has an ADAPTIVE CONTROL controller, which allows you to adjust the boiler operation based on air flow through the heat exchanger. It also handles 4 central heating pumps, hot water pump, valve, control of one mixing valve, viewing and changing parameters of the main controller online.
