The DEFRO OPTIMA KOMFORT PLUS A long-burning solid fuel boiler is the perfect choice for heating homes and holiday homes with an area between 80 and 350 m2. This series of DEFRO boilers represents a new generation of heating systems, equipped with an electronic control unit with a PID controller, which, by means of a blower fan, supplies air in a dosed manner to the combustion zone and thus controls the burning rate of the fuel, maintaining the desired temperature of the boiler, which does not exceed 85 °C. If the temperature in the circuit exceeds the set limit, the control unit reduces the air flow or stops it completely. Air distribution in the combustion zone allows maximum control of the fuel combustion process at different boiler powers. The boiler control system allows the connection of a temperature sensor to control the heating of hot water in boilers and 2 pumps, for heating and domestic hot water.
K3P controller with mixing valve control (S3P driver for 8 kW - ST-28 OPTI PID standard driver), DEFRO-MZ mixing valve controller with weather and water return sensor, GSM mode, INTERNET mode, NZ version for closed systems.
The construction of the boiler DEFRO OPTIMA KOMFORT PLUS A allows the use of the following types of fuel for heating the house or cottage: fine coal (coke) with top loading and top burning, wood, ecological coal, briquettes, sawdust. The DEFRO heating boiler has an efficient multi-stage heat exchanger made of P265GH temperature-resistant steel with a thickness of 6 mm, which ensures high thermal efficiency (up to 82%). Between the casing and the heat exchanger, as well as in the combustion doors, mineral wool is used as thermal insulation, providing maximum protection against burns in contact with the metal elements of the DEFRO boiler.
The DEFRO solid fuel boiler is equipped with a movable grate, designed for easier removal of slag and ash from the combustion chambers with the help of water. In its construction, a special pedal is provided, which, when pressed, causes metal teeth to emerge from the grate that break the slag crust, ensuring better air circulation and, implicitly, an improvement in combustion efficiency.
The evacuation of combustion gases in the solid fuel boiler DEFRO OPTIMA KOMFORT PLUS A is done through a smoke duct located on the back. Traction adjustment is carried out by means of a special valve in the smoke duct. By turning it, the thrust is changed, which also allows the combustion process to be controlled. The construction of the DEFRO solid fuel boiler and the well-thought-out location of the combustion doors allow easy cleaning of the internal walls of the heat exchanger and the smoke duct.
