Bottom combustion solid fuel boiler KV-Profi series 20-25 kW
Specifications
ADVANTAGES OF THE "KV-PROFI" SERIES BOILERS:
- Double thermal insulation of all boiler doors;
- The presence of a steel boiler shaft cladding: - neutralizes the negative impact of the cold coolant (water) on the combustion process, promotes more complete combustion of fuel and, accordingly increases the efficiency of the boiler,
- is an optimal solution when using various types of fuel, additionally protects the steel walls of the boiler from condensate;
- Availability of a grate shake-off mechanism;
- The presence of mechanical regulation of the thermal power (by changing the area of the grate) of the boiler - makes it possible to operate without reducing the efficiency of the boiler at lower capacities (during the off-season and warm winters), unlike boilers without this option, in which the efficiency in a similar situation is significantly reduced;
- The handle for adjusting the direct draft valve of the boiler is located on the front wall of the boiler for convenience;
- The presence of an additional air damper on the upper door of the boiler - when using fuel (wood) with high humidity;
- The ability to install heating elements on all boilers, i.e. the boiler can operate as an electric boiler;
- The ability to operate the boiler without electricity;
- Warranty - 5 years;
