HEATER 20 kW convection stove, with glass door. A robust firewood stove intended for production workshops, utility buildings, larger business premises, warehouses and halls.
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.
The glazed door on this version allows the fire to be observed.
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 660 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.
