I guess really you could say the whole thing sucks.:ROFLMAO:


Useless fact: You can have any size extractor fan in a bathroom, but it will only be as good as the air that can get in to replace it. Ideally there should be 1/2 inch gap under the door. (But it is rarely mentioned)
 
I fitted my own complete MVHR system when building my new self build house a couple of years ago. I was able to borrow the anemometer kit to set up all the flow rates, but having done that for my own peace of mind, building control never asked for any paperwork.

Excellent point.
I offer to install a vent in the customers door every time, or saw off a small layer on the bottom of the door. I explain, quite throughly, that the fan simply can't do it's job if it is unable to suck air into the room. Every customer has said they will do it them selves. Every time I return for another job a few months or years later.... no vent. :D
 
A little off subject...
Could anyone explain what the fan is actually doing if there are no vents for it to draw air into the room?
It will never be a sealed room, so there will always be a little air drawn in, but certainly nothing like a 100mm diameter hole.

I'm guessing the fan blades still rotate at the same amount per second, so what is it actually doing if its not drawing air in? Where is the balancing factor? I'm guessing the motor just becomes hotter as it's trying to work harder, as the pressure in the room has slightly decreased? So the balancing factor is more heat in the motor?

And keep the window shut in the autumn, winter and spring to keep cooler moist air out

This is rarely mentioned, and often people say this is irrelevant - which is nonsense as sucking cool moist air into a steamy room definitely won’t help
 
How is this ever going to be enforceable
If everybody shys away from installing fans is it just counter productive legislation that does the opposite of what was intended

Like everything else these days, it could only be enforced by BC on new builds, or when the rose fertilizer hits the fan, when no doubt, the ' governing bodies' will make a big song and dance about it.
 
If BC even knows it's supposed to inspect fans. Or anything else!! I have heard rumours that BC should be resposible for inspecting and signing off on EW insulation on tower blocks. I doubt if they give a flyinf f about fans.
 
Does this apply to like for like replacements/ maintenance repairs.
I'm passed caring. I'm just going to tell customers I no longer install fans as there's too much paperwork involved.

BC don't care as I've never had any checks carried out on any of the work I've notified.

I know that's supposed to be the point of the schemes but the most 1 customer has had was a quick 2 minutes phone call to ask were they satisfied. No technical check up that I actually carried out any testing.

It does make you wonder if those of us who pay to be in the schemes are the actual mugs and those that don't are the ones making the money.

I know plenty of electricians who are not scheme members who carry out notifiable work but never notify anyone.

Alot don't even issue any certs so until the customer sells its never questioned and even then they pay £40 and take out indemnity insurance so they don't have to pay out even if it goes tit's up.

The system doesn't work. Until we have something with the same level of legal backing like Gas Safe ( and even that isn't perfect I'm led to believe ) and DIY Dave can't buy a consumer unit from B&Q or Screwfix or online without having credentials things won't change.

Either that or manufacturers price units so high to retailers but then discount if a registered installer purchases one.

Wholesalers used to work like that. If you paid cash you got charged retail.
If you had an account with them then you got charged wholesale.

We need to do something or no one is going to want to train to be a sparky.

Monday rant over. Can you tell I've had a bad weekend 🤣🤣🤣

Well I will still be working on them. Only the other day looked at my partners mums tweaked the timer on the overrun.

I am pretty sure its NO...

As generally building regulations and/or wiring regulations etc.. are NOT retrospective..!

So "Like-for-like" maintenance replacement work on an existing installation that was done to the correct standards when it was installed is outside of the scope..

Plus, as an electrician would you issue any electrical certificate for disconnecting some wires from one fan then reconnecting the same wires onto a new fan??

I wouldn't as I have installed NO additional wiring!!
So how is anyone going to chase-up any non-notifications for swapping a fan???

That would probably be counter productive as Dave then installs a cheap and nasty one that he’s bought from dodgy Joe.
