Poor air quality can be attributed to many problems arising in the workplace or in the home. It is believed to contribute to a significant loss in productivity, low morale and higher rates of sickness amongst many employees. The object of providing good ventilation alongside air conditioning in residential and commercial buildings is to provide conditions under which people can live and work in comfort and safety.

Developed and refined over the past 30 years, the ventilation systems that Heacol Ltd use have perfected the recovery of waste energy. The units reduce overall energy costs by extracting stale air and then recovering the heating or cooling energy to either warm or cool incoming fresh air. By utilising this energy, the system can save up to 30% on initial capital costs of heating and cooling equipment and up to 80% of running costs.


  • Effective ventilation The Ventilation unit’s simultaneous air exhaust/supply provides effective ventilation. Conventional ventilators, (i.e. Extract propeller fans) do not work effectively within air tight buildings because of the negative air pressures involved.
    • Good energy recovery Total heating (sensible and latent) recovery provides a comfortable air temperature within the room. The energy saved by using the ventilation systems contributes towards lowering the heating or cooling requirement within the building, therefore reducing the energy requirement and running costs.
    • Free cooling function - When the outdoor temperature is lower than the indoor air conditioned temperature in the summer, Ventilation provides fresh outdoor cool air to reduce the indoor air temperature.
    • Good sound attenuation - The core of the units that we use for Ventilation systems in conjunction with the Heat Pumps provides outstanding performance levels resulting in almost silent operation.
    • Part L2 Building Regulations
    With the introduction of Part L2 (Part J in Scotland), new building design is changing to become more airtight, as well as energy efficient. The need for fresh air has remained the same however and thus poses new challenges for modern design. The Heat Recovery ventilation we use fully meets these challenges due to its basic principal and its efficient heat recovery.
