- Particularly compact design
- Easy operation and maintenance
- Good heat utilization through airtight insulation and large surface area for heat transfer
- Adjustable secondary air supply for good combustion values even in the upper flame area
- Suitable as an emergency heating system, since it can operate without power
- Uncomplicated regulation
- Insensitive to low chimney drafts and tarring
- Safety heat exchanger for closed systems
- Four-piece cleaning set included with delivery
