Heating Solutions
Tube Heaters
Schwank radiant tube heaters are ideal for a wide range of heating applications, including those with average to low ceiling heights. A flame is shot into a hollow steel tube radiating with temperatures with up to approximately 600° C [1100° F]. Schwank tube heaters offer supreme efficiency and performance since the flame is up to five times longer than in most competing products.

Innovation: a further innovation is a 2-stage feature, which is widely known from boilers and luminous heaters. This technology allows controlling the heat output according to the actual heat requirement. This is because it is not always best to heat at full throttle – heating economically saves energy and improves heating comfort.

Application Areas:

  • Industrial units

  • Logistics buildings

  • Sport facilities

  • Show rooms

  • Churches

The Advantages of Schwank Tube Heaters:
  • High energy-efficiency: 30% - 50% energy savings vs. conventional systems

  • Even distribution and comfortable warmth

  • High Return on Investment (ROI)

  • Very short warming-up time

  • No hot air cushion  below the ceiling

  • Possibility of partial heating of specific areas and different temperature zones

  • No dust swirls or draughts

  • Quality, durability and comfort

  • Easy installation

  • Made in Germany


Our tube heaters distinguish themselves in particular in the energy-efficiency, i.e. low operating costs and  short pay-back periods. The following criteria explain specific & unique features.
