DMEV (Decentralised Mechanical Extract Ventilation)

Save on your energy bill and provide your home with clean, fresh air. 

Decentralised Mechanical Extract Ventilation  

Save on your energy bill and provide your home with clean, fresh air. Every home needs fresh air to come into the building from outside, for you to breathe. It’s also vital that stale and damp air and pollutants are removed – both for your health, and the integrity of the building.

Opening windows and doors – so-called purge ventilation – teamed with extractor fans in kitchens and bathrooms will do the job, but of course causes heat loss. To ensure that you are saving energy but also creating a healthy home, it’s vital to consider how the house is ventilated. Decentralised Mechanical Extract Ventilation systems are a solution. They exchange stale air for fresh air, and recover heat in the process.

What is a DMEV system

 

 

A decentralised Mechanical Extract Ventilation (d-MEV) system is a low energy, continuous mechanical extract ventilation system designed to draw moisture laden air out of the wet rooms (bathrooms/utility and kitchen) providing a quieter and more efficient system compared to intermittent fans.

The Building Regulations Approved Document F gives examples of four main methods of ventilation. System 3, Continuous mechanical extract ventilation can be achieved using a single centralised extract unit such as the Sentinel Multivent ducted to ‘wet’ rooms (kitchen, bathroom, en-suite and WC) or by decentralised individual fans, such as the Lo-Carbon Response in the ‘wet’ rooms. The fans run continuously at near silent levels providing a simple and effective form of ventilation.
