What are the Health and Environmental Benefits of MVHR Systems?

MVHR systems, or Mechanical Ventilation and Heat Recovery systems, are increasingly popular for a number of reasons. While the promise of saving money is one of the benefits, there are environmental and health reasons as to why they should be installed. What are the health and environmental benefits of MVHR systems? And how are MVHR systems able to deliver these benefits to their owners?

The Energy Saving Benefits of an MVHR System

Heating is a major contributor to both your utility costs and carbon footprint. Installing a good MVHR system could result in huge savings while reducing your energy load. Nuaire heat recovery units, for instance, can help reduce energy costs by up to 25 percent without having to sacrifice comfort, since they recover up to 90% of the heat in the outgoing air. This reduces your need for fossil fuels by up to a fourth and you don’t have to do anything else but upgrade your heating and cooling system.

Another benefit of MVHR systems is that they allow you to enjoy good air quality without sacrificing energy efficiency. When we slow down the fans that circulate air in the building, it can become stuffy. People react by opening windows, letting in fresh air and letting out the air you just paid to heat or cool. In contrast, the MVHR system increases air circulation without wasting energy. It also allows you to make a building more air-tight and energy efficient without sacrificing comfort.

The Health Benefits of an MVHR System

Because MVHR systems turn over the air so often in your home or office, there is less opportunity for condensation or mould to form. This reduces the risk of associated respiratory problems. If there is mould or dust in other parts of the home, the accelerated air circulation and filtration by the MVHR system will help control it.

MVHR systems keep humidity at acceptable levels. This is invaluable if chronic damp aggravates conditions like arthritis. At the same time, you can have an MVHR system maintain humidity levels so that the air doesn’t become too dry either.

A side benefit of upgrading to an MVHR system is that it will purify the air, removing the cleaning chemicals and toxic outgassing that may contribute to sick building syndrome. A WHO report suggested up to a third of old buildings leave residents suffering from SBS.

The Additional Benefits of MVHR Systems

MVHR systems are a key component in Passivhaus or ultra-energy-efficient buildings. These passive homes that use a minimum of energy rely on super insulation, extremely airtight buildings, a minimum of thermal bridging, maximised passive solar gain, and MVHR. By regularly replacing used air with fresh air while simultaneously transferring the heat, they help your home become very energy efficient without sacrificing comfort.

When you don’t have uncontrolled draughts thanks to improved insulation and a better ventilation system, there won’t be hot and cold spots in your building. Nor will anyone have the temptation to bring in a small heater to keep warm.

MVHR systems are being integrated into existing buildings and new construction because of their many benefits. If you want to enjoy better air quality, reduce your energy load, and save in the process, MVHR is definitely the way to go.
