Winterwarm XR+ Gas fired unit air heater

Technically equipped for modern, industrial and commercial buildings, due to reduced overall dimensions and vast application possibilities.


The second generation XR-unit air heaters with unique characteristics:

  • ErP-2021 compliant in accordance with the latest EcoDesign directive.
  • Horizontal and vertical air distribution: the heat exchanger and the premix-burner are constructed in such a way that the unit air heater can blow-out in any desired direction.
  • Improved air distribution: high air output with large throw and an air discharge pattern which ensures a good mixture of the air.
  • Non-condensing: the seasonal efficiency complies with the ErP2021 requirements but still no condensate drain is necessary. Very suitable for those locations where a high efficiency HR-heater wíth condensate drain is not possible.
  • Gradient-control: two temperature sensors, one inside the heater and one in the working zone, measure continuously the temperature gradient when the burner is not in function. As soon as the temperature gradient gets too high (i.e. it gets too hot underneath the ceiling), the fan of the heater will switch on. This way the generated heat is utilised optimally. The unit then functions as a destratification fan; the number of destratificationfans can therefore be limited.
  • Comfortable: if the roomtemperature gets too low, the burner will switch on automatically. The modulating premix-burner then generates the precise amount of heat required together with the three-stage fan. This way a hall is heated in a very comfortable way.
  • Energy efficient: the above characteristics of the XR+-range contribute to a very low energy consumption. Energy savings of approximately 15% are possible in comparison to conventional unit air heaters!
  • Installation friendly: because the XR+ is very compact, the heater is light and easy to handle. Moreover the unit air heater can be mounted with two suspension points or with four suspension points.
  • Modern: the XR+-range has a modern, attractive design. In combination with its compactness this heater is a good alternative to install in “in sight” locations like showrooms, cafeterias, shops, etc.
  • Available capacities: 12,7 kW (XR 10+) – 20,5 kW (XR 20+) – 28,8 kW (XR 30+) – 41,1 kW (XR 40+) - 50,7 kW (XR 50+) and 61,2 kW (XR 60+).
