recommendation on new bathroom extractor fan please

Magic_x_uk · 24 Oct 2017 at 07:48

Hi, our bathroom fan has started becoming somewhat noisy, Bearings perhaps are on the way out.

Looking for a suitable replacement.

It is one of those that is fitted onto the bathroom wall and then duct vented to the outside wall.

The present one comes on with the bathroom light and stays on after you turn the light of for a pre-set timer duration.

Bathroom is your average size. Just needs to shift the steam etc when we shower.

thank you

block up the whole and take the opportunity to install an inline fan in the roof

I have seen those, but the issue I have is I would need to get someone in to do some work as I believe you have to vent out the roof tiles?

Also whilst were talking about things.

There is 5 downlighters in the ceiling of the bathroom, they do not not particularly well sealed into the loft, Should they be, was thinking of taking them all out, plaster boarding over the holes an fitting a single ceiling light in the bathroom.

I bought an integrated down light and extractor fan to place in my shower, and I think bought a larger extractor unit which tripled the amount of air being extracted. The duct runs from the ceiling, through the loft and out of a vent in the roof.

Correct but I would 2nd getting an inline extractor. The biggest benefit of them is you get the same/better performance as a wall one but they only generate a fraction of the noise (will vary depending on what your loft insulation is like), it's a a bit of fath having to route it and install it but it's well worth it.

I bought an Envirovent Silent 100 Design on the basis that it seemed to be the best looking one out there. Performance seems pretty good, we barely get any steaming up.

I would have liked a celing extractor but the bathroom is flat roofed so no room above.

You might be able to pipe out under the eaves, thats where ours goes in the loft. I replaced with an inline unit "Manrose MF100T" which is pretty beastly. Has an off delay function which you can set between something like 2 to 20 minutes as well as low/mid/high via jumpers in the unit. Pumps 3x the air and doesn't sound any louder

Agreed, we put ours on a separte switch so we can choose when to be extracting or not. I.e when in the bath, we don't want the extractor whirring away.

One of the humidity sensing ones would be good but they were a bit more expensive.

have the same one, even with the jumper set to high it is silent compared to a "silent" through the wall fan, with good extration. Made a hole through the gable end of the roof for the outlet.

I have 2 holes in the ceiling currently (one in en-suite and one in main bathroom) where there were vents but no fans previously. This then has some sort of venting pipe much like the one tumble dryers have going up into the attic and out the roof.

The previous owner had taped the vents up with white masking tape. i imagine this was due to them causing a draught. this got me thinking. are they even needed? can i not just plasterboard the holes up and open the window when in the shower? this means i get rid of moisture but also keep the home well insulated.

I bought a manrose inline fan to replace our ceiling fan and whilst yes it extracts more air than the previous fan and yes it is quieter, it still doesn't clear steam from the room whilst we shower

The likelihood is that passive venting via an open window isn't sufficient. You'll then end up causing mould etc from moisture build up in the house.

It's also part of the new part F (I think) requirements to have a fan in bathrooms so it seems pretty bad idea to remove. Does it have a non return flap on the outside to stop drafts?
