Most people have heard of heat recovery systems by now. They are becoming commonplace in new homes. But there are many misconceptions about what they are and how they work.

Here’s everything you need to know to understand heat recovery systems.

What Is A Heat Recovery System?

A heat recovery system is a home heating system that recovers warm air you would otherwise lose to the outside world. The heat from this recovered air warms fresh air drawn from the outside. This new air, now warm, is then pumped back into the home to warm it.

Recovering heat in this way reduces the homeowners’ need to generate more. Not only do heat recovery systems enable homeowners to reduce their heating bills. They also offer several other benefits.

How Do They Work?

Heat recovery ventilation systems extract stale, warm air from your home at the same time as they draw fresh, cool air from the outside. A special unit enables the system to extract the heat from the warm airflow and transfer it to the cooler one.

This heat exchange occurs rapidly as air flows through the system. Because the air flows are kept separate, there is no chance of any cross-contamination occurring. A filter ensures that the air drawn from the outside is as clean as possible.

A network of ducts throughout the property control how the system distributes warm air.  It operates independently of other heating systems in the home. By enabling users to reclaim heat and energy that would otherwise be lost, heat recovery systems improve the efficiency of any heating system they are paired with.

What Are The Benefits?

There are several benefits to using a heat recovery system:

  1. Save money on your energy bills.
  2. Improve the efficiency of any heating system(s) you pair with it.
  3. Improve the quality of air in your home. Ensure a constant circulation of filtered outdoor air.
  4. Reduce the number of allergens in the air and alleviate hayfever, asthma, and other allergies.
  5. Many systems can also function as ai conditioning units, exchanging air but not heat during the summer. Check with your supplier before you buy to see if they offer this feature.

Can Heat Recovery Systems Be Installed In Existing Homes?

Yes, you can retrofit most properties with a heat recovery system. Companies like can use radial ductwork just 75 mm in diameter to make the necessary modifications to just about any home.

How Much Does A New System Cost?

Numerous factors will affect the cost of installing a heat recovery system in your home. As a general rule, the smaller your property is, the cheaper it will be to install a system. However, the larger your property is, the more you will feel the benefits of the system.

The best way to ascertain the price of installing a system in your home is to contact a supplier and ask them. If you give them the specifications for your property, they can provide you with an estimate for the total cost involved.

Heat recovery systems are an excellent way of saving money and keeping your heating bills as low as possible. For people who are sensitive to allergens and pollutants, these systems can also be hugely beneficial.
