Heat recovery how does it work

A heat recovery unit allows the internal air renewal of the premise, maintaining and recovering the energy used for air conditioning. The main objective of a heat exchanger or heat recovery system is the recovery of the energy by transferring the heat of the air that is extracted from the inside of a premise to the air that is driven outside. A heat recovery unit is basically composed of a directly driven fan, an exhauster and a heat exchanger, all perfectly assembled and joined inside a thermal and noise insulated structure.

The internal extraction air circuit pass by the exchanger without mixing with the circuit of the external driven air. Heat recovery systems are great at saving money, and the planet, by using less energy and running off mains electricity rather than natural gas.

This can reduce the need for extractor fans in kitchens and bathrooms, as the air in your home is constantly circulated and refreshed by the heat recovery system. The fresh air is not only heated, but also filtered. This means it is free of many of the harmful particulates that can affect asthma sufferers and people with respiratory problems. The installation and operation of heat recovery systems is actually very simple and quick to perform, and often less intrusive and disruptive than installing a traditional home heating system.

Though a 21 st century technology, there are many companies that have a lot of experience in designing and installing heat recovery systems for homes and offices. At BPCventilation. More and more homes and businesses are having heat recovery systems installed to replace aging water boilers that are expensive to run and maintain.

Heat recovery systems are a much more economical way to warm a space, and the money saved helps the systems pay for themselves very quickly. Linkedin Twitter.

A set of pipes go all throughout your residential home, and there are two separate lines of pipes for both filtered and incoming air. These two never mix, so there is never a chance for cross-contamination of the different airflows. The entire system is connected to air valves that go into each room through a carefully constructed network of ducts. A heat recovery system greatly reduces the negative impact on the environment because it recycles the already existing air to produce thermal energy.

That way, we use what we already have and reduce the amount of heat we lose out whenever we heat our residential homes. These systems can also be manufactured to use water, as opposed to warm air. Contrary to popular beliefs, an HRV works separately to your normal heating system. Each room has a ventilation system that draws the air, replaces it with a new one, and takes the old one to the main heat recovery unit.

The heat recovery unit moves the stale air through one set of pipes and draws in new air from outside. The stale air is then being filtered out of negative pollutants and put back into the atmosphere.
