So this client from Tunbridge Wells emailed us asking what we might be able to do for him...

he had come to realise this winter that the ducting for his bathroom extractor fans was a little leaky, and resulted in him using an oven pan underneath the biggest culprit to stop the water leaking out onto the bathroom ceiling and causing wet patches and water marks!

No problems. Lets sort this one out. Their current set up was two ceiling DMEV extractor fans, one in the main bathroom, and one in the ensuite, were ducted together across a span of about 6 meters, joined at a Y-piece which led on out through a loft vent. 

We're quite upfront with the work we undertake. 90% of installations we happen upon tend to have some glaringly obvious weak attributes (or obvious to us, at least). and a high percentage of our projects often mean a complete rip out and a complete fresh installation. A lot of extractor fan systems just don't meet our design criteria for optimal performance, and as such can't be put to good use as part of our well-known high performance extractor fan systems.

We managed to talk our customer into moving where the two vents on the bathroom ceiling currently were - and I think once we had finished building the extraction systems they came to realise why we often push for the design choices we do. In our heads, it just made sense. And sometimes it is hard to convey exactly what we mean in words, because a lot of the airflow principles, and vapour behaviour, have to be imagined in your own head.

So we set to work! We realigned the bathroom ceiling vents to the roof tile vents - and got our go-to roofer to fit an extra roof tile vent in, and replace the one that was already there. We built up ramp structures to not only support our new extractor fan systems, but also to line both extractor fans up from the bathroom ceiling vent below, to the roof tile vent above. This allows maximum available airflow, and is part of ustrying to apply as many good design principles as practical to ensure our clients get the most out of their extractor fan systems.

We fitted condensation traps to both new extractor fan systems, as low as we could but still enough height to give fall to any condensate that does arrive in the trap, and piped up our condensation together and out to a shared gulley with the help of our roofer (thankyou for your assistance!!)

Both original extractor fan vents were removed, and replaced for nice white decorative ceiling vents that wouldn't look amiss in a hotel bathroom suite.

The original holes were 'made good' that is, hole filled ready for plastering, sanding and painting.

As part of the manufacturers instructions for our favourite in-line fans, we introduced a 3A fused spur into the circuit to offer the protection required by the installation manual. 

And finally we ducted up, installed the external insulation to the ducting, performed our electrical tests and fired them up!
