Choose in freedom : at the first installation or with an existing boiler

The twinning of a wood burning boiler and an oil boiler may be done at the first installation or later, for example in the case of an existing oil boiler already installed.

The boilers may be connected into the same chimney or into 2 seperate chimneys.

Thanks to the twinning kit, the wood burning boiler and the oil boiler can be connected into the same chimney, as it controls that they do not work simultaneously.

Furthermore, the twinning kit ensures the following functions :

• The wood burning boiler is always prioritary. When the wood burning boiler works, it automaticly stops the oil boiler.
• In case of lack of wood, the oil boiler takes over automatically.

A wood burner in an oil boiler

The wood burning boiler works as a wood burner in the oil boiler. All services previously provided by the oil boiler are done the same way by the wood burning boiler (i.e. : domestic hot water, under floor heating systel, radiators,...)

The heating installation is not modified. No work inside the house is required. All work is done in the boiler room.
