What is heat recovery?

Our heat recovery systems improve air quality and reduce energy consumption using counterflow heat recovery technology. Waste heat is extracted from warm, polluted air as it leaves the building and transferred to cool fresh air as it flows in. The heat recovery unit can work in isolation or in combination with the Building Management System (BMS) Controller on site to automatically adjust the fan speed. This maintains optimum air quality, based on data from CO2 sensors located within the building. With air2air heat recovery, efficiency rates of up 90% can be achieved.

Types of heat recovery systems

There are four heat recovery  models available:

All these heat recovery units can be used as a standalone solution in conjunction with a duct system in the building, or as part of a complete Biddle climate system together with:

  • The NOZ Range of energy-efficient air heater & coolers, which provide comfort in large rooms with high ceilings
  • Comfort Circle Cassettes, which combine heating, cooling & ventilation in one ceiling unit are ideal where a false ceiling is in place
  • The Biddle range of air curtains and fan coils

Fully compliant with the latest UK and European legislation, the Biddle heat recovery system can reduce CO2 emissions associated with heating and ventilation by more than 90%. When used in conjunction with a renewable heat source, such as a heat pump, our heat recovery solutions also cut energy generated from fossil fuels to zero, even during periods of peak demand.
