Boiler PEREKO KSW Alfa 12 kW
The KSW ALFA boiler has been designed uses a proven design confirmed by many years of operation. The current design has been improved and attention has been paid to the smallest detail. This is the boiler with the most straightforward design in our product range, but at the same time, it is highly efficient and proven in heating small and medium-size buildings. It is designed mainly for coal firing, but it can also be successfully used to burn other types of fuel.
Its straightforward design translates in practice into straightforward operation. This boiler can be easily operated by anybody who has previous experience. To make fuel charging even more convenient we have widened the firing door and positioned them slightly diagonally. For ash removal from the grate we mounted a handy lever on the side of the boiler. It is enough to pull it down and consequently the all the ash will fall down into the ash pit.
We improved the conventional design by adding extended flue gas circulation. Thus we have succeeded in extending the working time with a single charge. Consequently this boiler with such a firing system will consume less fuel.
The boiler was designed to enable subsequent easy upgrading – to add a controller and a fan. Additional subassemblies enhance slow burning and make the boiler firing-up process easier thanks to the improvement of the chimney draft. When the user prefers conventional operation we suggest using a combustion controller. It maintains the set hot water temperature through the mechanical control of air inflow into the combustion chamber.
