Wood / log burner are available in different sizes for installing in an existing open fire place or as a new design concept.
Here we have fires which are working just with normal air circulation or with fan assitant systems. As options we can distribute warm/ hot air with flex tubes into the same room or into other rooms .
It is also possible to prepare hot water and to feed a central boiler with it.            

All wood burners are efficent if they have a glass fronted may be with a sliding glass door or with a normal glass door. Open wood fires have an efficiency of approx.  30 % of heat output into the room.
