The difference between MVHR and DCV

When it comes to home ventilation systems, two of the most popular options are MVHR (Mechanical Ventilation with Heat Recovery) and DCV (Demand Controlled Ventilation). Both of these systems offer great benefits, but they also have some key differences that you should be aware of. In this blog post, we’ll take a look at what sets MVHR and DCV apart and help you decide which system is right for your home.


MVHR systems are designed to provide a continuous supply of fresh air into the home, while also recovering heat from exhaust air that is being expelled from the home. This allows for a more efficient system, as the heat-recovery process can reduce energy costs associated with heating the home. The downside of MVHR systems is that they require a significant amount of energy to run, as well as regular maintenance.


DCV systems are more energy efficient than MVHR systems, as they only run when needed. This means that the system will only start running when the air quality in the home is in need of improvement, thus reducing energy costs. DCV systems are also easier to maintain, as they have fewer components that need to be monitored and maintained.


When it comes to deciding between an MVHR system and a DCV system, it really comes down to your individual needs and preferences. If you’re looking for a system that requires minimal maintenance and is energy efficient, then a DCV system may be the best choice for you. However, if you are looking for a system that offers a more continuous supply of fresh air, then an MVHR system may be the right choice.
