The condensing unit air heater which combines efficient heating with energy savings and high comfort.

Winterwarm HR-series Characteristics Winterwarm HR:

  • High efficiency (on ECA list)
  • Energy saving (up to 25% compared to conventional heaters)
  • Stainless steel heater exchange as standard
  • Modulating burner
  • Open-therm Control

For many years now, suspended unit air heaters have been employed worldwide to heat industrial buildings. Research from the ‘Gasunie’ (NL) regarding various industrial heating systems has confirmed that direct heated gas-fired air heating is one of the most efficient heating methods.
