I’m not entirely sure why you felt the need to get offended on behalf of @marshian especially as he responded with a laughing emoji? The comment I posted was ripped off from the Men in Black film, and was meant to be light hearted. I do not in any way condone the killing of a spouse to get your own way regarding the building of a Shabby Chic Bar.

I presume you told her that her terms were acceptable?

Don't! It'll be sweet, and if not it's really easy to clean. Let me know if you have any dramas when you getaroundtoit, splitting the fan casings and getting to the nitty gritty/mouldy slimy is really easy (when you've got the fan units out)

Probably right, I won’t be doing that for another three and a half years 😃

I took the extract fan housing to pieces, it was a bit grim on closer inspection but I was expecting a lot worse so I’m pretty chuffed and I don’t think I broke anything in the process which is a great result 😃 I’m pretty sure my pre filters have helped, and not turning the MVHR on until all the building work had ceased can’t have hurt things either. I’m wondering if the fact it’s an enthalpy unit helps as well? It was bone dry inside and I’m presuming there will always be some moisture inside a non enthalpy unit?

Got them out. So to remove the fan's I followed the instructions by giving a sharp tug and rotating the fan housing out (reversed for the fan on the other side). The next step in the instructions wasn't working for me without making me nervous of causing damage so I found that I could lift up the fan housing (orange arrow) by just a small amount which was enough to allow the rest of the steps to be followed without issue.

The manufacturers instructions for removing the fans make it look incredibly easy, the reality for me is that it isn’t, feels like I’m going to damage the polystyrene internals trying to get the fans out. Does anyone have any ‘top tips’ for the fan removal of a Brink Flair 400 MVHR (or anyone have superior Googling skills - I can’t find anything) ~~~ I’ve left it far too long to finally get around to cleaning my MVHR heat exchanger and fans (3.5 years!) but it looks like I’ve got away with it. Frankly I’m amazed how clean it is in there. The dirtiest component is the fan on the extract side which I guess is to be expected. Intake fan Extract fan

Yes, please do. It’s very interesting but complete Swahili to me. I would like to learn a new trick if you can spare the time (and start with the basics!)

I’ve got one in the garden on my weather station but annoyingly it quit recording the Solar Radiation a while ago. Consequently I’ve substituted Solar Radiation with PV Production so I can continue to bore my wife witless with my statistics. 😃

@JohnMo do you think you have a have problem then? We have had wall to wall sunshine down here for the last few days with hardly a cloud in sight so not at all atypical.

Significant difference down south. 27th Feb - 4th Mar 2024 26th Feb - 4th Mar 2025 The most noticeable result of the increased solar is the decreased heating requirement (the house is around 21 degrees). The heating last turned off at 05:30 on the morning of the 27th Feb and it hasn’t been back on since. It doesn’t look like we’ll need any this week and maybe not next week either despite negative overnight temperatures, down to around -4 to -5 on recent nights. Epic.

That’s a good point. We have zinc, formed on site and 600mm centres. 400mm would have looked better. Pigeon shite eventually doesn’t wash off completely either, so if you can get anti roosting wires/spikes fitted economically consider those as well.

@Onoff that is a genius suggestion. I’m now trying to find something around here that I need a Quinetic door switch for. @Pocster have you had a look at the videos on the product page in the link.

Thanks for that explanation @John Carroll much appreciated. 👍🏻

That's interesting, I've never seen temperatures even close to that after 6 hours of running. I've turned the pumps down as well to slow down the rate of flow, perhaps I need to turn them down further? I do have a 7°C temperature drop between flow and return which I believe is optimum. Out of interest, what size is your UFH system? Mine is 824 meters of pipe (no idea how many litres that equates too). @John Carroll Thanks for those figures. What is the maths, I can't work it out? That and @ProDaves comment certainly indicate that there is no benefit from isolating one of the Willis heaters, but the lived experience is different for whatever reason.
