We were invited by a client in Hoo - quite a very well known client in Hoo, in fact - to take a look at their poorly bathroom extractor fans and see what we can do for them.

The existing extractor fan systems as they stood, were pretty much unserviceable. at least 2 out of 4 fans were literally swimming in water - with the fan and ducting full to the brim with condensation that has just collected and collected over the cold winter months. How there wasn't really bad patches on the ceilings below I do not know!

It was just, all in all, quite a poor design as it had currently stood. Airflow was certainly not optimised. No consideration for reduction of condensation, and certainly no consideration for discharging condensation, if any was to accumulate. We collected nearly half a bucket of water from these ducts! 

We proposed our systems and told the customer there is currently not much we'd want to reuse from the existing systems at all. We explained the design processes and what the new system would like, and why some of these design choices were made, to help them get maximum airflow out of their bathroom extractor fans, how to minimise condensation accumulation, and a discharge route for any condensation that does appear inside the ventilation ducting.

A job well done by the residential ventilation specialists serving Medway & Maidstone!
