Long burning solid fuel boilers Gefest profi U


Long-burning solid fuel boilers G.Profi U   are intended for heating residential and industrial buildings. The manufacturer has provided 2 lines for capacities from 15 to 250 kW and from 350 to 1000 kW. A wide range of models allows you to choose the most efficient boiler for your needs. G.Profi U boilers performance range: 15, 25, 40, 50, 70, 100, 150, 200, 250, 400, 500, 600, 800, 1000 kW. The main advantage of G.Profi boilers is a highly efficient convection system, thanks to which a high level of efficiency is achieved - up to 95%. 

Any solid fuel is used as a fuel in G.Profi series, including fuel with high humidity. Fuel combustion is based on the principle of direct pyrolysis with air distribution to additional combustion zones. The gas temperature is no more than 90 °C, therefore the boiler design does not provide for the installation of a thick-walled chimney. The heating medium is distributed in such a way that virtually no condensation occurs. In the absence of electricity, the boiler operating in a natural circulation system will be able to create operating pressure for further heating the room. The G.Profi boiler is controlled by a microprocessor, which can easily adjust the operation of the boiler when changing the fuel. The enlarged loading chamber allows working up to 24 hours using wood and 48 hours using coal. Also, G.Profi U boilers are equipped with an audible alarm and explosive valves. 

The design of the G.Profi boiler is made of 6 mm thick boiler refractory steel. The body is insulated with a thick layer of mineral wool, which prevents the loss of heat calories. Thanks to the multi-level vertical heat exchanger, the flue gas path is increased and, accordingly, the heating capacity of the unit is increased. An inspection hatch is provided at the top of the boiler, which facilitates access to the convection ducts.

When developing this model, the engineers took into account all user preferences and developed a sloped loading door, which greatly simplifies the filling of fuel into the combustion chamber. The power of Gefest Profi boilers is indicated when burning wood with a moisture content of 30%, when burning coal, the nominal power increases by 40-70% of the declared one. The water jacket is hydrostatically tested at 4 bars.
