Boiler DEFRO BIO Slim 15 kW 5 CLASS

DEFRO BIO Slim 15 kW wood pellet boiler with feeder

RELEVANT INFORMATION

DEFRO BIO Slim 15 kW is a modern pellet boiler with a feeder, meeting the strict 5th class standards, with Ecodesign certificate. The fuel tank is placed directly above the heat exchanger, thus minimising the dimensions of the boiler, making it an ideal cooker for small boiler rooms. The three-pass construction with a low-temperature exchanger in the form of a cylinder allows maximum utilisation of the heating surface; the flue gas passages in the form of horizontal pipes contain swirlers, economisers and thick asbestos-free mineral wool thermal insulation allowing maximum utilisation of the heat energy from the flue gases.

The DEFRO BIO Slim 15 kW boiler is also equipped with a modern, intuitive and easy-to-use controller with a touchscreen colour display APC3 ADAPTIVE CONTROL. The pellet burner has an igniter and a self-cleaning system, making the cooker much easier to operate. The exhaust fan, on the other hand, eliminates the problem of inadequate chimney draught. In addition, it has sensors so that the controller cuts off the power to the fan and the geared motor when the water temperature exceeds 95°C. An additional thermometer with a capillary tube serves as a substitute reading of the boiler outlet water temperature. Thanks to modern solutions, the appliance ensures safe and comfortable operation. Certificates allow subsidies of up to 70%.
