HEATER 50 kW convection stove. A robust firewood stove intended for large industrial, storage and agricultural halls requiring rapid air heating.
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
- Rapid heat transfer by natural air circulation without an electric fan
- Grate-free combustion on a continuous bed of ash, with simple air-supply control
- Firebox for logs up to 900 mm long
- Robust steel construction suitable for regular use
Output selection: the stated heated room volume is a maximum guideline. The required output depends on heat loss, insulation, operating conditions and chimney parameters. Check suitability for the actual installation.
