HR 100

Heat recovery units for single rooms

The heat recovery units for single rooms have been specifically designed to eliminate excessive moisture and so helping to prevent condensation with the inherent risks to property and health whilst retaining up to 80% of heat contained within the outgoing air.

The range is available in 230v or 12v models depending upon installation criteria. All models run continuously on trickle speed and have various options to change to fast speed - see model table below. Mounting Kits Available in Brown, White, Terracotta and Stone.

All units are manufactured to have balanced airflow so as not to interfere with conventional gas boilers / heating systems where negative air pressure within a problem may cause a problem.

Suitable for: Single rooms

  • Wall, Window or Ceiling mounted
  • Integral Humidity Sensors
  • Energy saving manual Pullcord override
  • Two year no quibble guarantee
  • Recovers up to 80% of heat that would otherwise be lost
  • Simple Installation
