V bad condensation in bathroom

[CrabappleCake]

Live in north west so usually cold, damp and wet outside so leaving window open seems counterintuitive.

Water running Dow walks after shower or bath.

We've got a heated towel rail that comes on with the central heating for a couple of hours in the morning and in the evening.

A fan but it's ten years old.

It's an old Victorian house with a big north facing window and an unoccupied house next door so no heat from there.

Do we need to open window more, get a higher powered fan, leave the towel rail on all the time? Some combination of the above..

Dolly, is it illegal to take plugged items into a bathroom? Your link doesn't quite back up your previous post. Genuine question.

Watching with interest as we run a bathroom extractor and a dehumidifier and our windows still stream!

the linked article is not very accurate.

It is not "illegal" to take an electric appliance into a bathroom, in the sense that there are no Electrical Regulations Police who will burst into your house and arrest or prosecute you. It is not even "illegal" to put a socket in a bathroom. However a socket within three metres of a bath does not conform with the electrical regulations, so an electrician who fitted one could not truthfully issue a completion certificate saying that it complied, so your installation would not meet Building Regulations.

However, the maximum penalty for taking portable electrical appliances into the bathroom is death.

Ordinary switches are permitted in a bathroom provided they are at least 600mm from the footprint of a fixed bath or shower.

"Part P" applies to all electrical work in a dwelling-house, not just to bathrooms.

The entire wording of Part P is shown here. It is much shorter and simpler than people think. I make it 28 words.

One very popular method of demonstrating compliance with Part P is to carry out the installation in conformance with the current edition of the Wiring Regulations referenced in BS6761. Which are much longer. Other methods are possible.

I understand physics. But if I open my bathroom window when it's cold and wet outside the warm wet air in my bathroom is replaced by cold air AND RAIN from outside, which puddles on the windowsill.
Because of the direction of the prevailing wind and the orientation of the building the slightest breeze results in very strong airflow through the rest of the house and a significant temperature drop.
So my bathroom window remains firmly shut between November and March and I run a dehumidifier in the bathroom when the bathroom is vacant, plugged in (as I said) outside.

BS7671 I mean.

A snip at £85.

Thank you PigletJohn for clarifying that. I was trying to keep to simple terms that people might understand. But as always with any rules, there are those who think they don't apply to them

It's fine to keep things on simple terms if you don't understand the details but make it clear it's your opinion don't suggest it's illegal and dangerous!
The rules about not using mains powered dehumidifiers in the bathroom don't apply to anyone as they don't exist.

So how come shaver sockets are allowed to be sited fairly close to taps albeit higher up?

Shaver sockets have an isolating transformer which means there's no connection to any earthed metalwork in your house. This means it's harder to get a shock. It also means you can only use class II ie no earth pin appliances in it, which is fine because all shavers and Ruth brush chargers are.

Had anyone got a quite dehumidifier? Mine (from Homebase) are powerful but noisy.

I had an Ecoair that was quiet. It lasted about 3 years.

Please all read the sentance half way down PigletJohn's paragraph. I beleive he is someone who can be trusted to give us the truth.

Bit patronising there...
