DHV-25N Heat Recovery Ventilation Unit with Pre-Heat & Auto Bypass Function


The DHV-25N is our base unit for our N range. This unit comes with both the pre-heat and auto bypass functionalities, allowing the incoming air to be warmed when it’s cold, and bypasses the heat exchanger when its warm.

Like our other units, the DHV-25N has a removable aluminium heat exchanger which recovers up to 90% of the heat exchanged. On it’s lowest setting, this unit has an air flow of 160m³/h, with the option to boost to 220m³/h on mid speed, and 250m³/h on high speed.


  • Up to 90% heat recovered
  • Suitable for domestic properties up to 150m²
  • Ideal for use in larger homes, and smaller commercial properties (dependant on your requirements)
