Dead electrical ends!

[sportstait]

I am presently revamping the entire bathroom. This includes putting in a new tongue & groove ceiling. The existing shower pull switch will remain and I'm going to take down the current light and replace it with a plain pendant fitting. No real problems there, that seems straightforward enough.

What is perplexing me however, is the existing extractor fan. It will be coming down and won't be replaced. The question is...what do I do with the electrical wires that are up there and have been powering it? Once the unit is taken down, what should I do with the wires?

Any help greatfully received

you might regret not fitting a fan in a bathroom. The cable that has 3 cores at the light will be the fan. Use a tester to prove it before ripping cables out. New builds have to have fans as well as triple pole isolators and Im not sure if your revamp qualifies on that score. Someone here will correct me if needed.

You need to trace them all and remove them. Are you going to have a fan? The building regs call for an extractor fan.

I was going to say, isn't it mandatory to have a certain level of mechanical ventilation???

by pendant i take it you mean ceiling rose and light hanging down or similar?

it is easy to do, but one "slight problem" you can not have a pendant light in a regular bathroom

bathrooms should have enclosed, recesssed or waterproof lights

nooooooooooooooooooo pendants in a bathroom!!!!!!! missed that bit.

maybe he's related to mr walker?

No pendants in the bathroom eh? Back to the drawing board.

I think I'll just buy a new extractor fan and be done with it. I'll just swap one for the other. And buy a new light fitting!

Thanks for the information everyone

why not buy an extractor fan with a light in it (its not a joke they do exist)

I missed the pendant as well!

AFAIK, its not mandatory in the building regs to have an extractor fan, I believe they just demand a certain level of ventillation and fans are mentioned in the approved doc and no one really tries to meet the requirements any other way. I might be mistaken though.

There was a brief attempt to sell upwards-ventilators that were basically a pipe going up through the ceiling, the natural tendency of warm moist air to rise takes it out quickly and silently. They have a tremendous throughput (greater than a fan) but people over here aren't used to them, and in winter they take out so much warm air that they make the bathroom feel cold.

If there was any money in it, I'm sure they could be installed with a hit and miss or iris or something operated by the light switch.

You are not mistaken. The regs just call for ventilation, and extractor fans are the easiest way to do it. Another method I know about that has been approved (in the one case) is using a big fan to blow air into the house (from the loft) creating a positive pressure throughout so that air is gently forced through the vents in the bathroom. Seems ridiculous to me, and I can't see what's wrong with extractors - I'll happily put up with the noise so that the mirrors don't steam up!

It would be nice to know how you can meet the extract rates set out in Section 1 of part of Part F without an extract fan?

With Air handling units thats exactly what superstores do except they return the air back up to the units for cooling/heating.
