The boiler KSW Alfa Plus is equipped by the factory with a LOGIC system controller. It controls the operation of pumps and a forced draught (FD) fan. This boiler performs well in complex installations with central heating and a hot water pump and (thanks to its high capacity) in buildings with a higher heat demand.
The body, housing and additional equipment for this boiler were selected in order to simplify its operation. The built-in controller accelerates the boiler firing-up process. The enlarged firing door is slightly tilted upwards thus facilitating fuel charging. Fast ash removal from the grate is supported by a handy lever located at the side of the boiler. We also made changes to the boiler design itself. They cannot be observed with the naked eye, but the effect of extended flue gas circulation can be seen when observing the boiler’s slow burning capability of up to 18 hours and lower fuel combustion.

As one of the few boiler producers we equip all our products with adjustable doors. If the firing door loses air-tightness due to frequent operation, then it can be adjusted horizontally, recovering the air tightness.
The Alfa Plus boiler is based on a robust design. Its proven design and careful manufacturing process ensure many years of fuel-efficient operation. This model is covered by the following warranty terms: 2-year warranty for subassemblies, 6-year warranty for heat exchanger tightness and 10-warranty for weld density.

- Automatic: Hard coal.
- Substitute: Wood, crushed coal, coal/coke mixture, coal/fine coal mixture, pellet, hard coal briguettes, brown coal briquettes, edgings and chips. 

- 10 years for weld tightness.
- 6 years for the tightness of the exchange unit.
- 2 years for subassemblies.
