For builders, electricians and plumbers who want to get knowledgeable about installing MVHR systems, we do offer a bespoke training, either on site or in-house. Please contact us if you would like to book a training appointment.
We would recommend this for all who first install our systems, even if they have done other ones beforehand.
Please see below for some of the common mistakes made in the installation process.
- Ducting material should be stored in a clean environment, best with end caps on, so the it is kept clean inside.
- Deviations in the layout, e.g. extract valves next to the door can cause short-circuiting of air flow
- Penetrations through the thermal envelope need to carefully sealed and often need to be insulated to avoid interstitial condensation.
- All joints need to be sealed in a permanent fashion. Avoid PVC ducting, especially rectangular ones as they are difficult to get airtight permanently and cannot be cleaned any more.
- Avoid flexible ducting. If it needs to be installed in short lengths, it needs to be fixed with jubilee clips to avoid air leakage.
- Don't omitt silencers, but use the correctly specified ones for the supply and extract duct connections. Your end-customers will thank you.
- Ducting in cold loft spaces is often problematic. Ideally keep all supply & extract ducting fully within the thermal envelope to avoid heat = performance losses.
- An eye for detail and taking pride in quality workmanship makes the difference.
