This brand is made in Poland. The KSP DUO models (shown here) can burn five different types of fuel which is convenient and can save you money by using the cheapest fuel. The KSP PELET model burns wood pellets and has a rather large external hopper which takes up more space. All of the boilers have electronic controls and can control three different pumps for zones or central heating and domestic hot water production. The warranty on the heat exchanger is not very good when compared to other brands.

The units feature refractory ceramic combustion chambers and three step air for complete efficient combustion. The units are made in France but they are only available through their authorized installers and the warranty is not very good when compared to other brands.
