The innovative design of furnace in the KSW Master boiler, enriched with air injection system  allows using the majority of solid fuels in this boiler. A system of water pockets is used in this boiler. It extends flue gas circulation  and improves its efficiency. A characteristic element of this boiler is effective combustion of fine coal and option to fire it up from top and bottom.
Boiler operation is supported by electronic controller . It controls operation of the fan  located in the upper part of the boiler and reduces fuel consumption by 10-30% and extends operation time on one charge. It maintains a high temperature in the boiler without risk of overheating.
KSW Master is designed to ensure reliable and effective operation for many years. Long lifetime is ensured by its design - mainly good metal sheets connected with double joints. Warranty periods for this model: 2 years warranty for components, 5 years warranty for heat exchanger tightness and 10 years of warranty for flue gas tightness.
Each charging boiler requires every-day servicing. Therefore, we try to make it as convenient as possible. Wider charging doors  facilitate charging of fuel and cleaning of the combustion chamber. The lever of grate  is located on the side of the boiler. One shift allows removing the ash to the ash-pan  from where it can be easily taken out. As one of the few manufacturers we ensure also option to adjust doors in a horizontal position to maintain its tightness.
Hard coal is the most often used type of fuel for heating the house.
High calorific value and relatively low price are the main factors decisive on its popularity.
Fine coal has similar properties to the hard coal but its price is considerably lower.
It has a form of fine granules, which can be used as an additive to the other solid fuel or independently.
PEREKO boilers have high heating power with relatively small dimensions. It is also possible to install them in smaller boiler rooms.
The connection of boiler to the chimney is not longer a problem due to universal connection ensuring high accessibility.
A lever located on the side of the boiler services mobile grate set on a slight angle in vertical motion what facilitates removal of ash.
Professional controller individually adapted for each boiler. Its operation does not require professional knowledge from the user.
Additional vent holes located in the combustion chamber allows combusting various types of fuels.
