The benefits of heat recovery ventilation

Many property owners are familiar with the benefits of investing in effective insulation, double glazing and extractor fans, including improved heat retention and a reduction in condensation and damp problems.

An additional improvement that can be made is the installation of heat recovery ventilators. These systems recover the waste heat energy in the stale, exhaust air from a space and use it to warm the fresh, inlet air.

Modern building regulations require homes to be air tight, preventing draughts and heat loss; as a result, the air in the home can become stale and humid, resulting in discomfort and potential health problems.

General benefits of heat recovery ventilation

The most obvious benefit of heat recovery ventilators, which are available from suppliers such as https://www.restorationuk.com/condensation-products/single-room-heat-recovery-ventilators/product/kair-heat-recovery-room-ventilator-k-hrv150, is the energy saving potential. By using waste heat to warm up incoming air, a reduced load is placed on the boiler and heating system to heat the building, thus saving cost.

Using heat recovery will also improve the quality of the air in the building. Contaminants such as pollen and dust will be removed, and the humidity of the air will be lower. This eliminates problems with condensation and subsequent issues with mould and damp.

Business benefits

Businesses are interested in maintaining a ‘green’ profile and reducing their carbon footprint. The large boilers used to heat commercial properties can be improved by increasing efficiency through the use of flue gas economisers. These units absorb waste heat from the flue of the boiler, which can then be reused to preheat the incoming water to the boiler, thereby reducing the energy used in heating from cold.

Employees will benefit from a consistent workplace temperature and humidity, thereby improving working conditions and raising morale and work efficiency.

Industrial applications could see even greater energy savings; without heat recovery systems, a significant quantity of heat is lost.

The future

Further developments in heat recovery technology will lead to improvements in the ability to extract waste heat from other sources in and around homes and businesses and use it to reduce energy costs and carbon footprints.

Heat recovery is not right for every property; for example, older buildings often have a greater number of draughts and heat can be lost through a variety of outlets. The cost of retrofitting heat recovery systems and associated ducting can also be expensive.
