Luminous heaters

efficient, fast and quiet

We invented the luminous heater and that’s exactly the difference. Schwank luminous heaters are used in industrial and commercial buildings, logistics facilities and workshops. The core component is the Schwank ceramic tile, invented by the company’s founder Günther Schwank. It is still manufactured by us in Germany. The infrared energy is generated by the combustion of a gas-air mixture in the ceramic tile. The surface of the ceramic tile heats up to approximately 950 °C, glows “red hot” and emits infrared radiation. Reflectors direct the radiation downwards into the common area. Pure performance and efficiency!

Luminous heaters are also characterised by their especially clean combustion with extremely low NOx values. A feature that is becoming increasingly important.

Luminous heater principle

The functioning principle of a luminous heater is as simple as it is brilliant: Gas, normally natural gas, but also propane as well as biogas, is mixed with air in a mixing chamber and directed through the approximately 3,500 combustion channels of the specially developed ceramic tiles. The mixture is ignited just before its outlet. Thanks to the extremely close-knit combustion channels, the ceramic tile is heated to approximately 950 °C. This results in the formation of radiation energy, which is subsequently directed, by means of highly reflective reflectors, to the exact location where it is required: in the common area of employees.The principle of our heating systems has been copied from nature. The heat rays of the sun travel through the air without heating it and emit their thermal energy only when they fall on surfaces. The Schwank infrared heaters use the same natural technology to heat buildings in an energy-efficient manner. The infrared rays are converted into heat at the point of contact, for example, on our skin but also on the floor, machines, stored goods and products. Heating therefore takes place where it is required. The surfaces absorb the thermal energy and, in turn, re-emit it into the environment. This results in a balanced micro-climate made of air and radiation heat, which is very pleasant for the employees. The energy costs are reduced significantly and the feeling of comfort is enhanced for the people. As compared to conventional systems, savings generally amount to between 30%-50%. 

Bis zu 14% weitere Energieersparnis

Apart from the desired room temperature, the minimum outdoor temperature of the respective location also forms the basis for the calculation of the heat requirement of buildings. For instance, it is -16 °C for Munich. In order to ensure that the building maintains the desired target temperature even at these temperatures, the heating system is designed for these minimum temperatures. In other words, this means that the heating system is oversized for 95% of the time. Similar to your car, the heating system consumes the most energy under full load. Since the full output is required only rarely, the full modulation offers the option of adapting the output to the actual requirement. Up to 14% of the energy can therefore be saved. Additionally, the modulation enhances comfort. While single-step solutions show severe fluctuations in the actual temperature, a fully modulating system by Schwank can be flexible in adjusting its output. As a result, the actual and target temperature lie significantly closer to each other and temperature fluctuations are avoided.

Advantages of full modulating systems:

  • The adaptation of fuel and combustion air to the actual heat requirement increases the overall energy efficiency.
  • The life time of heaters is significantly extended due to the reduced number of switching cycles.
  • Since there is no need to restart the system, “purging” with air is not required. This can avoid unnecessary heat losses and saves energy.
  • The lower exhaust gas temperature leads to a lower exhaust gas speed, whereby there is more time to dissipate heat from the hot gas to the device.
  • Owing to the reduced cycles, the formation of non-combusted pollutants that arise during the start-up can be reduced.
