Solid fuel boiler Burnit WBS Magna 160 for central heating of large premises up to 900m². Constructed for solid fuel burning - wood, wood briquettes class B and coal.
Steel Solid fuel boilers satisfy the heating demands of large sized spaces. Owing to its smart design, WBS Magna 160 is easy to transport and install in spite of its dimensions. The boiler can be direct connected to either closed or open loop heating system. The design allows for fitting with pellet-, oil- or gas-fired burners.
Compliant with norm EN 303-5, class III.
The boiler body is manufactured from high quality steel. The combustion chamber has a large heat exchanging surface and low chamber impedance. Large firebox door ensures easy loading even of large wood logs (up to 100cm long). The loading door also has a combustion viewer for monitoring the burning process. With a maximum operating pressure of 4 bar BURNiT WBS Magna is capable to feed a large-scale heating system. Convenient inspection door in the upper part of the boiler ensures easy cleaning of the flue exhaust tubes.
To increase the heat exchange, the combustion chamber is designed for a three-pass flue gas flow. The mantle completely envelops the firebox for maximized usage of the heat, and has the exhaust gas tubes immersed into it for even higher heat exchanging surface. The boiler's body is insulated from the external conditions by thick high temperature resisting wool. The model uses a thermostatic draught regulator that opens or closes a flap on the lower door, depending on the amount of air needed for the burning process. The casing and insulation of the boiler can be removed for transport or maintenance.
For a safe and reliable operation of the boiler, a number of safety devices are installed
- Pressure relief valve 4bar (not included);
- Thermostatic draught regulator;
- Chimney draught flap;
- Safety heat evacuator: a tap-water filled line passes through the uppermost part of the boiler body. In case of overheating it is triggered open by a thermostatic valve (not included) to evacuate the heat off the boiler.
The central heating boiler can operate with natural untreated wood, but also with coal and compressed solid fuel such as briquettes. Maximum length of the wood logs is 800mm. Fuel moisture should be 20% or lower.
In order to use the maximum caloricity of the fuel, the wood logs should be dried for a prolonged period of time. High moisture levels reduces caloricity and the output power of the boiler.
This series of boilers is manufactured for burning solid fuel, with the option of adaptation to a different kind of fuel. This is possible by mounting a pellet, gas or an oil burner on the lower door opening. A flange is also needed to mount the burner (optional).
