Per-Eko KSW Prima despite its small size, has one of the largest combustion chambers available on the market. So much so that it can burn chunks of wood more than half a meter in length! A wide, upper-facing chute door facilitates the process of fuel loading, whereas the mobile grate facilitates the process of clearing out ash.

High fuel efficiency. The KSW Prima boiler is equipped with an innovative control system, Logic which controls the central heating installation pump, hot current water pump as well as connecting with the room thermostat. It also ensures constant and effective work of the fan as well as automatically selecting the speed, thus reducing or increasing fan rotation momentum depending upon the heat requirement. This extends the period of unaltered combustion characteristics of the boiler (i.e. the length of time the boiler works with one chute) and over the course of a year ensures a high level of fuel efficiency.

Clean combustion of various types of fuel. The boiler was constructed in such a manner as to facilitate the process of its cleaning. Additional air blow locations within the furnace allow the use of different types of fuel.
