We use the WHO-175 heater mainly on construction sites and have not had any issues within the last 2 months. The device works perfectly.
It has proven especially beneficial during construction outside on the scaffolding. We place it under the scaffolding so that heat can move evenly from below and heat the entire side of the building.
In the construction of private houses, we use it to keep the interior warm during interior finishing works. At first, our biggest fear was the construction dust which could ruin the device, but experience has shown us that if you clean it with compressed air in a dusty environment more often, then it works perfectly in those conditions.
Very economic, especially compared to a diesel cannon, and emits more warmth without creating a draft in the room.

We use Weltem WHO-175 in a big arched hall (400-500 square meters) where we repair drilling machines. The product has proven its value so far, and we are extremely pleased with the purchase. We have had no setbacks, and the device works without any interruptions. The biggest advantage of this product is that it is portable – you can move it everywhere. We have always had the problem that when we place a heater inside the hall, it starts to heat the entire room, and all this takes a lot of time. Weltem heater is mobile, so we can place the heater in the exact area where we are repairing the machines and the work area gets instantly warm. If the product does indeed have a long life cycle and continues to perform as well as it does, then we can say with confidence that you have brought a SUPERB product to the market!
A heater is the best infrared heating device with a fuel burner on the market. Weltem or Airrex heaters are suitable for use in indoor as well as outdoor conditions without the need for a separate flue tube. In order to heat a 500 m2 room, the heaters consume only 2-3 litres of diesel or biodiesel fuel per day. Unlike traditional fan heaters, infrared heat spreads evenly in all directions and feels pleasant even when standing next to the heater. The heater has durable wheels which make it easy to move around.
