Project Services

The Heat Recovery System ‘Built’ around you

We understand how important it is to consider Mechanical Ventilation with Heat Recovery when designing the structure of a building, which is why the service we offer is designed around your project’s specific requirements. From a single room MVHR unit to full scale contracts covering a whole house MVHR system, we can design, supply, install and commission. We also offer maintenance and ongoing technical support for whole house ventilation systems.

1. Specification

Once we have established your outline requirements a budget figure for your MVHR project will be prepared. Providing this figure is acceptable, we will then prepare a detailed specification to ensure compliance with Part F Building Regulations 2010 (where required).

This will comprise BR Part F Airflow Calculations & product selection; and is based on airflow rates & any additional client preferences (brand, control options such as wireless & humidistat, summer bypass, pollen filtration, etc).

What we need to know:
