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!
We use the heater on construction sites and move it to different rooms when necessary. Dusty conditions have not proven to be a problem if you clean the device once in a while. We purchased the Weltem WHO-115 model, because at first we wanted a device that was not too big and one that would be easy to move. The WHO-115 model does its job well, but we have understood that in our conditions we could actually use an even bigger and more powerful model.
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.
