Description
DEFRO GAMMA is a boiler installed in central heating systems. This boiler has emission class 5 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 facilitated by the use of ceramic catalysts that stabilize the combustion process. The heat exchanger is made of high-grade boiler steel. The shape of the heat exchanger ensures high efficiency and easy cleaning. Thanks to its innovative structure, it has the ability to move the fuel tank to the other side. It also has an ADAPTIVE CONTROL controller, which allows you to regulate the boiler operation based on air flow through the heat exchanger. It also operates 4 pumps for central heating, hot water, valve, control of one mixing valve with the ability to view and change the main controller parameters online.
