HEATER 20 kW convection stove, with water heat exchanger 10 kW. This set combines a HEATER stove with a compatible water heat exchanger, providing convection heating for the room and heat transfer to a water-based heating system.
Room heat output: 20 kW. Water-side heat output: 10 kW.
The tubular body uses natural convection: cooler room air enters at the bottom, warms in the tubes around the firebox and flows back into the room without a fan.
This tubular-stove design follows the principle introduced by Eric Darnell in 1975. This appliance is a HEATER-brand product.
Key features
- Room heat output: 20 kW. Water-side heat output: 10 kW.
- Natural warm-air circulation without an electric fan
- Firebox for logs up to 660 mm long
- Fuel: dry firewood
Professional installation: the water circuit must be professionally designed, protected and connected. The stated heated room volume is a maximum guideline; actual output requirements depend on the building heat loss.
