Thanks again, everyone. Just to be clear, the current situation with water drips isn't persistent, nor a huge amount. It's more of a minor nuisance that happens occasionally. Just to clarify, the vent in the roof is actually mounted on the ridge tile, so definitely the responsibility of the...

Yes, there is a more fundamental problem with the capping on the vertical flue, which I'm not prepared to address just yet! The existing fan is woefully inadequate and in the wrong location, and has no condensation trap. I think most of the moisture is running down the inside of the vertical...

That's great, thanks. I figured the thrust from the fan would be better immediately after the fan, and hopefully allow the shutter to open wider.

Hi John I see what you mean. That was why I was considering an S-bend at the bottom of the vertical flue to trap water and debris. I would make a point of clearing it out every six months (hence the litter tray). But an S-bend may restrict the flow too much, so perhaps I'll try and put a...

Thanks, John I wondered as much, and is probably a stretch too far for this application. They don't strike me as having the same sort of air-shifting properties as a dedicated fan, so will give this a miss for now, thanks.

That's fair enough. As a matter of interest, going off at a slight tangent... ...do you have any experience with |Single Room Heat Recovery Systems? I'm not sure if one would be suitable to this application. :unsure:

Hi guys Thanks for your responses. I've updated my diagram to try and eliminate the U-bend and make the airflow less restrictive. I've also found that this company do a 110 mm to 100 mm convertor, so it should seat the vertical pipe a lot better...

Thanks for getting back to me. I like the looks of the Soler & Palau unit - it's like something you'd find under the wing of an airliner! It's a little pricey, though, and I'm not too concerned about the decibels. The noise for the existing Manrose fan is quite obtrusive, so anything I fit...

Thanks for the detailed reply. Yes, the existing fan has a timer, and I was going to buy one with a timer anyway. Thanks for the tip from TLC, but another one that caught my eye was this: https://www.extractorfanworld.co.uk/turbo-tube-pro-100-4-inch-inline-fan-with-timer-3785-p.asp What do you...

Hello again, everyone. It's been a while, but I have my next project that I would appreciate some input, please. Background: - First floor flat, with access to loft space. - Internal shower room with no window, no external walls. - Existing Manrose extractor fan is located in the ceiling above...

Thanks Harry. I figured that was the case, but you mentioned using a 3-phase contactor to control all of the heaters, so I wasn't sure if the circuit protection would be affected by having all radials on or off. Apologies also to you and MeldrewsMate for taking so long to get back to you...
