Bathroom extraction advice

Options
I have a bathroom and an en-suite that both currently have poor performing, noisy and clogged ceiling extractor fans.

I want to replace these with new fans but am unsure what to go for.

I could simply replace with some better ceiling fans (positioned properly and with solid ducting), put wall mounted fans in, fit an in-line fan in the attic or install heat recovery extraction to both rooms (or indeed all of the upstairs rooms) and have the remaining heat pumped onto the landing.

I am leaning towards the last two as I would remove most of the noise created by extraction from these rooms, I also have external wall insulation so would rather not punch any holes in this!

Any advice would be greatly appreciated.

Regards
Phil

    Can nobody offer me any advice?

    Would I be right in assuming that an in-line centrifugal fan might be capable of moving more m3 of air than a ceiling mounted fan?

    Would a ceiling mounted fan and a wall fan be similarly efficient or would a wall one be better due to not needing any ducting?

    Is having a heat recovery system overkill and will it remove moisture? I like the idea of having whole house heat recovery but I don't fancy running ducting to the ground floor so would just doing the top floor make sense if I chose to go down this route?

    Regards

    Leaning towards an in-line or a heat recovery system.

    Does anyone have a single room or multi room heat recovery system that is installed in a bathroom?

    You would be best speaking to an electrician to be honest.

    They have much more knowledge than joe bloggs on here.

    I put an in-line fan in for the bathroom in the last place, and it shifted a lot of air. These days I might go for a heat recovery system; although I haven't done a lot of research, I'm a bit sceptical on how much they really recover.

    But certainly when it comes to in-line fan in the loft, vs wall fan - in-line every time for me.

    It really depends - the heat recovery ones are good but expensive, so it depends on how critical that is in the over all picture - i.e. if you have a badly insulated or drafty house, no point in paying to keep some heat that you would be losing anyway!
    The inline fans usually give the best noise/air shifting and are the preferred option if you have enough space.
    Really comes down to budget

    Budget is not critical.

    The house is an old (1895), double fronted, Victorian house. It has a garage and carport on the side that is insulated to modern housing standards (it even has a decent insulated garage door) and it has also been eternally insulated (including the garage and car port) all the way around, most of which extends below floor level. It has 270mm insulation in the loft which may well be changed for some solid insulation in future.

    The double glazing is next on my list for upgrading as some are rather draughty! I will then be insulating the sub-floor leaving the cellar as the only uninsulated part of the house and it will be separated from the house by insulation.

    Once this is done most of the unintended airflow (draughts) in the property should be gone so heat recovery might be a good way to keep adequate airflow without loosing too much heat.
