Weltem WHO-175 is a medium-sized Fuel-powered infrared radiation heater in our product family, which as an easy-to-use and portable heating device is suitable for a wide range of uses. at Weltem
you heat industrial halls, garages, renovation sites, summer houses, terraces, tents and many other spaces where economical, safe and low-emission heating power is required from the heating device.
The infrared radiation produced by the heating device heats a solid, thermal energy-storing material, which stores and releases the heat into the surrounding space. The heat produced by the device is pleasant and even, and never too much
hot. Thanks to the three-part combustion process and the efficient solenoid that cuts off the fuel supply, no unpleasant diesel smell or carbon monoxide emissions enter the air. The device does not need a flue for exhaust gases, if
the ventilation of the space to be heated has been carried out according to the regulations. When heating living spaces, however, we recommend that the fire gases are led into the flue.
Weltem is a type-approved, very safe heating device in Finland with a comprehensive safety system:
• The motion sensor that turns off the device is activated if the heater falls over or receives a strong shock.
• There is an overheating protection inside the heater that turns off the device if the sensor temperature exceeds +105 ⁰C.
• Two-part fuel level monitoring. The heater signals the need for refueling with a beep.
• Timer. 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
• Temperature sensor fault detector

Warm-up example:
1000 m3 hall heating with WHO-175 heater
in winter conditions, the prevailing temperature of 0 ⁰C is raised
15 ⁰C, which is the daily consumption of the heater
about 4.0 l/day is obtained.
Fuel consumption may be the first
on days higher than the guideline values, but levels off
when structures heat up. In the future for heating
maintenance heat is enough.
