Do I need a MVHR system Design?
Skipping the design phase and relying on guesswork which means you might find yourself with too little parts, or too many which will slow down progress onsite. When we design, we get down to the specific details of your house and optimise runs for efficiency, performance and running noise.
Things to consider when comparing MVHR design/quotes:
- Do you have airflow calculations down to individual rooms - not just a floor area calculation or whole building ventilation rate?
- One duct run or two? Where higher rates are required in individual rooms, two duct runs are often designed to a single room valve to reduce noise - do you need this?
- Has the overall amount of ducting been calculated to ensure the unit runs at optimal speed and is not pushed too far?
- Is the ducting size making the system work harder?
Why does the install pack matter?
Alot of MVHR system problems are install problems.
These can range from squashed ducts, unsealed joints, missing insulation, valves never set correctly... and they don’t show up until commissioning, when the ceilings are already boarded.
The VentAssure™ pack walks your through every stage and gets each one checked off before the next starts. It was written from what we see on site, and you won’t find it anywhere else. Key documents include the best practise guide, first and second fix checklists and the airflow commissioning sheets required for Building Control.
