Mechanical Ventilation With Heat Recovery Systems

Mechanical Ventilation with Heat Recovery (MVHR) is the process of delivering fresh filtered air into your building without creating uncomfortable drafts, and without creating excessive demand on your heating and cooling systems. Find out how a ventilation system can improve your health and finances.

As modern homes become more airtight it is important to ensure that your home has good ventilation to avoid stale and unhealthy air. On a warm day you can of course simply open your windows and doors, but when the outside temperature is too hot or cold, this is not an option.

The most efficient method of ventilating your home is through installing an MVHR (Mechanical Ventilation with Heat Recovery) system which provides a continuous flow of fresh filtered air into your home while simultaneously removing stale or contaminated air.

With an MVHR system you control how much fresh air you’re getting, unlike when relying upon opening windows. The system operates continuously, doesn’t create drafts and uses very little energy, thus saving on your heating and power bills.

Some of the Benefits of Installing a Ventilation System
