Schwank’s Radiant Tube Heaters provide a comfortable and economical heating solution.

Gas Fired Radiant Tube heater

Innovative and Economical

Schwank’s infrared gas heater tube range offers low intensity heat and exceptional energy efficiency. By generating radiant energy, these gas heaters work on the principle of the sun, the heat being created when it comes into contact with people and objects.

 Gas Fired Radiant Tube heater

Low heat intensity makes Schwank gas heater tube systems particularly suitable for installation in low ceiling buildings. However, their excellent performance standards and system design flexibility mean that they can conform to a wide variety of building interior requirements. This flexibility is enhanced by the ability of radiant gas heaters to apply heating to selected zones, thus ensuring the most efficient use of energy and reducing operating costs.


Additionally, being suspended from the ceiling means that these gas heater tube systems maximise usable interior space, being at a level where they cause no obstruction to workplace activities. Comfortable working temperatures are produced where and when they are needed, with the gas heaters maintaining a discreet and unobtrusive presence.


Advances in gas heater technology


The core of the Schwank gas fired infrared radiant tube heater is the innovative "Whisper-Jet" burner. This is the result of continuous technical advancement and a long standing experience of flame tube heating.


Schwank offers its infrared burner systems with positive pressure fans, allowing Schwank gas fired radiant tube heaters to create a very long laminar flame which reaches far into the heater tube. This leads to a more uniform transfer over the tubes and an immediate positive effect on the energy efficiency of the overall Schwank gas fired infrared radiant tube heater system.


The radiant gas heater tube is warmed up to 650°C and generates comfortable radiant heat. A further benefit lies in the fact that the burner’s pressure fan is not exposed to hot flue gases and therefore has much greater longevity than conventional radiant gas heaters.


Products and Benefits


Schwank provides gas fired radiant tube heaters for the UK market in four energy-efficient classes:

  • superTube, our premium plus radiant gas heater tube
  • calorSchwank, our premium infrared gas heater tube
  • infraSchwank, a gas heater setting the standard in radiant heating
  • novoSchwank, our gas heater tube entry model in the gas fired radiant heating market


Advantages of Schwank ga fired infrared radiant tube heaters

  • Exceptionally high economic efficiency gas heaters
  • Uniform and comfortable flame tube heating
  • Short gas heater tube warm-up times
  • Long-life cycle and high comfort
  • No dust swirls or draughts with Schwank infrared radiant tube heaters
  • Schwank gas fired infrared radiant tube heaters offer "Made in Germany" Quality


Recycling waste heat


Furthermore, Schwank gas heater tube systems can be used in a unique low-cost heat recovery method which has been found to achieve increases in heating output of up to 110%. This is possible by employing Schwank’s tetraSchwank heat recovery system, together with the Schwank ThermoControl Plus intelligent heating control system to exploit flue gas heat without using any intermediate heat storage capacity or medium.


This works in the following way:

  • tetraSchwank is integrated into the flue gas tract of a Schwank tube gas heater
  • With a connected load of maximum 40kW, it recovers the heat energy contained in flue gas emissions through a counter-flow process using condensing technology
  • Heat recovered by this method is reintroduced immediately into the building


This heat recovery method serves the dual purpose of further the reducing operating costs and environmental impact of radiant gas heater systems that are already highly energy efficient.
