Heat recovery systems are ventilation systems that work by extracting and supplying air to provide a consistent, high-quality, indoor environment. The system ensures homes and commercial premises have fresh, highly filtered air, while retaining heat that would otherwise be wasted.
Who uses heat recovery systems?
A heat recovery system can be installed in domestic premises, as well as in the business sector. Any commercial business premises can have a heat recovery system to supply a cleaner and more constant environment for employees all through the year.
The technology can be particularly helpful in industrial plants and factories, where large rooms with high ceilings are a feature – particularly businesses such as distilleries and food manufacturing plants.
What are the main benefits?
The main benefit is a constant supply of warm, clean, fresh air, creating an interior environment with a superior ventilation system. Using the heat recovery system will help you to reduce your energy bills, whether at home or in the workplace.
Humidity and condensation will be better controlled, benefiting occupants’ health and ensuring the building’s walls and structure aren’t affected by damp over a period of time. The property is less likely to be filled with irritants, such as pollen and pollution, and the level of carbon dioxide will also be reduced.
The savings on energy bills can be quite significant – since the warm air is being recovered, it takes some of the strain off your boiler. In the case of large boilers used to heat business premises, they can be fitted with flue economisers to further improve heating efficiency. This can extend the boiler’s lifetime, as it won’t be subject to sudden high temperatures that can cause greater wear and tear.
How important is recycling the air?
The system extracts moist and stale air from the interior of your home or business premises and recycles it, recovering the usually lost heat and supplying the property with clean, filtered, fresh air. Stale, dirty air is continually extracted from every room.
The dirty air travels through the ducts back to the heat recovery unit. It passes through a plate or rotary wheel heat exchanger, until it reaches the required temperature and is then discharged again. The heat requirements are controlled automatically by the heat recovery unit controls. This means all of the building’s occupants will continually be breathing in clean, recycled, fresh air at the required temperature, creating a healthier environment for everyone at all times.
What is the future of the systems?
The industry is getting used to the existing technologies, while continually investigating new ideas for increasing the efficiency of heat recovery systems. In today’s climate, the focus is on extracting energy from renewable sources, both for domestic and commercial properties.
There is a demand to use “green” sources to help preserve the planet. This is particularly apparent in Stockholm, Sweden, where a revolutionary new system has taken heat ventilation systems to a new level. The innovative new system is extracting the heat produced on Stockholm’s underground and using it to provide heating for nearby offices. So far, this technology has reduced energy consumption in the offices by 25%.
