WDH-BGP 031S electric fan heater – 3 kW with hose connection
The WDH-BGP 031S is a high-performance 3 kW electric fan heater for construction sites, workshops, warehouses, trade, and industry. Thanks to the round air hose connection with a 19 cm diameter, warm air can be directed specifically into certain areas or rooms.
Important note regarding the power connection:
The WDH-BGP 031S requires up to 13.6 A at full heating capacity. A suitably fused 16 A socket is required for safe operation. The unit has a T23 connection; a matching fixed adapter for Switzerland is included in the delivery. A standard 10 A socket is not suitable for operation at full power.
3 kW heating capacity for rapid warmth
With a maximum heating capacity of 3000 watts, the WDH-BGP031S quickly generates warm air and is particularly suitable for heating workspaces, construction sites, workshops, garages, and commercial premises.
The electric fan heater operates without an open flame or combustion. Consequently, no additional oxygen is consumed during heating, and no exhaust gases are produced in the room.
Special feature: The integrated connection for a warm air hose allows the heated air to be directed to where it is needed. This is particularly practical when warmth is required not just directly in front of the heater, but in a specific area.
Round hose connection with 19 cm diameter
The 19 cm air duct connection allows for connection to a suitable warm air hose. This enables the warm air to be specifically distributed or directed into hard-to-reach areas.
-
Ø 19 cm hose connection for targeted warm air distribution
- Air circulation of approx. 348 m³/h
- Suitable for professional applications on construction sites and in workshops
- Ideal for targeted heating of individual work or room areas
3 operating levels – including fan mode
The WDH-BGP 031S has three operating levels. In addition to two heating levels, the unit can also be operated purely as a fan.

Infinitely adjustable temperature control
The desired temperature can be infinitely adjusted from 0 to 40 °C via the mechanical thermostat. The fan heater automatically switches the heating function on and off according to the selected temperature.
Robust electric fan heater for professional use
The WDH-BGP031S has a robust construction made largely of metal and is designed for regular use in demanding environments. An integrated carrying handle makes it easy to transport between different locations.

No oxygen consumption during heating
In contrast to gas or diesel-powered heaters, heat generation in the WDH-BGP 031S is electrical. No combustion takes place. Therefore, no oxygen is consumed from the room air during heating, and no combustion gases are produced.
This makes electric fan heaters particularly attractive for indoor use, provided the available power connection is designed for the required capacity.

Frequently asked questions about the WDH-BGP 031S
What is the heating capacity of the WDH-BGP 031S?
The WDH-BGP 031S has a maximum heating capacity of 3000 watts or 3 kW. Additionally, it can be operated at 1500 watts or without a heating function in pure fan mode.
Can warm air be directed via a hose?
Yes. The WDH-BGP 031S has a round hose connection with a diameter of 19 cm. This allows the warm air to be directed specifically.
Can the unit also be operated only as a fan?
Yes. In addition to the two heating levels of 1500 and 3000 watts, a pure fan mode without heating function is available.
How is the temperature set?
The desired temperature can be infinitely adjusted between 0 and 40 °C via the mechanical thermostat.
How much air does the WDH-BGP 031S move?
The fan heater achieves an air circulation of about 348 m³/h.
Does an electric fan heater consume oxygen?
No. No combustion takes place with the WDH-BGP 031S. The heat is generated electrically, so no oxygen is consumed and no combustion gases are produced during heating.
Is the WDH-BGP 031S suitable for construction sites?
Yes. The robust unit was developed for professional applications and is suitable for construction sites, workshops, garages, warehouses, and commercial premises, among others.
What kind of socket does the WDH-BGP 031S require?
At maximum output, the power consumption is about 13.6 A. Therefore, a sufficiently fused 16 A socket is required. The device has a T23 connection and is supplied with a matching Swiss fixed adapter.
Can the WDH-BGP 031S be operated on a standard 10 A socket?
A 10 A socket is not suitable for operation at full 3000-watt power. The power connection must be designed for the maximum power consumption of 13.6 A and fused with 16 A.
Is the fan heater splash-proof?
Yes. The WDH-BGP 031S has protection class IPX4 and is therefore protected against splash water. However, the respective operating conditions and safety regulations must still be observed.
How heavy is the WDH-BGP 031S?
The electric fan heater weighs only 4.9 kg and can be easily transported thanks to the integrated carrying handle.
