Secure heat supply. With flexible dual-fuel burners.

The Weishaupt WGL30–40 compact dual-fuel burners (240 to 1,875 MBTU/h)

Weishaupt dual-fuel burners offer the flexibility of gas or oil-fired operation. In normal operation, gas is generally used as the main fuel. Remote fuel changeover between gas and oil can be easily effected via the optional Modbus/ field bus expansion module.

Energy saving
Exemplary efficiency

Digital combustion management ensures that the burner only produces as much heat as the Boiler  needs. The oil pump is driven by a separate motor and is disconnected when the burner is firing on gas, which preserves the pump and saves electrical energy. The electronically controlled air damper closes fully on shutdown to prevent cooling of the combustion chamber.

Modern fuels

Weishaupt oil and dual-fuel burners are generally suitable for oil and low-sulphur oil (#2 oil as per ASTM D396). Bio-oil blends up to B10 can also be used in the same way as standard oils without any need for concern – guaranteed

Quiet operation

The air inlet housing is sound attenuated, which results in a noticible reduction in noise Emissions .


Years of experience and development work have gone into Weishaupt burners. Only the best materials are used in production.

Favourable price-to-performance ratio

The specially developed Mixing assembly  works with lower gas connection pressures. That makes it possible to use smaller-diameter valve trains.

Perfect electrics

The Combustion manager 's integrated connection console and its coded and numerically labelled plugs leave no room for doubt. They enable components to be removed quickly, reduce maintenance work, and prevent connection errors. Simple and perfect!

System solution

Digital combustion management offers the possibility of communication with other systems. That enables remote control, monitoring, and fault diagnosis, as well as integration with building management systems.

Information. Detailed, comprehensive, interesting.
