Weltem WHO-250 Fuel-powered infrared heater with fan

Fuel-powered infrared radiation heater developed and manufactured by Weltem, suitable for many different purposes. The Weltem heater is great for heating garages, halls, renovation sites, summer cottages and terraces. For everything where economical, safe and low-emission heating power is required from the heating device.

The infrared radiation produced by the Weltem heater heats a solid, thermal energy-storing material, which stores and releases the heat into the surrounding space. The heat produced by the heater is pleasant and even, and never too hot. The heater emits no soot or visible smoke. The device does not need exhaust ducts for fire gases, if the ventilation of the space to be heated has been carried out according to regulations, e.g. garages, terraces, tents, etc. When heating living spaces, the exhaust duct needs to be taken outside.

The Weltem heater is a very safe heating device with a comprehensive safety system:
• If the heater falls over or receives a strong shock, the motion sensor that turns off the device is activated and the device turns off.
• The heater has an overheating protection that turns off the device if the sensor temperature exceeds +105 ⁰C.
• Two-part fuel level monitoring. A signal tone indicates the need to refuel.
• Timer clock. The device can be scheduled to turn off automatically.
• Flame arrester
• Ignition safety system
• Power failure detection system
• Fuse
• Burner protection
• Burner start-up fuse
