Information

WITO type central heating furnaces are low temperature heating furnaces designed for water heating in both pump and gravity installations. Those central heating furnaces are used for heating of residential, one or multi-family buildings, public buildings, such as schools, offices, trade buildings, production buildings and many others. WITO central heating furnaces can be used in installations of open-heating systems only. They are produced with the capacity of: 10 - 48 kW.

In the case of the Płomyk controller, the user needs only to set the water temperature of the boiler and the controller will automatically adjust the amount of air. Carefully matched fuel- air ratio results in the high performance of the combustion process.

Advantages of the central heating boiler

Big refueling door
Easy operation, especially within the range of cleaning
The central heating boiler operates in semi- automatic mode
Increased life span and high efficiency

Fuel type:

fine coal

coal

wood

briquette
