Ventilation in utility room

[Pigriver]

We are trying to make our cramped kitchen a little nicer as we aren't planning on moving for a few years. I'd like to move out condenser dryer from the kitchen to the 'utility room' which is really an open under stairs cupboard and a bit of hallway leading to an unused down stairs loo. There is an extractor fan in there but my DH is concerned as the electrical fuse box is in the hall area and he thinks it will all get too steamy and affect the electrics.
It is a newish decent dryer and I think with a good extractor it will be ok but hey what do I know!
Any ideas if this is doable?

the point of an extractor is to take the water vapour away (leave the door and window closed for best effect), and leave the fan running during and after each cycle, until the room feels dry and the window is nor misty.

All condenser dryers emit a bit of steam, some are worse than others.

If the consumer unit is on an internal wall, it will not usually be cold enough to suffer condensation. A metal one (uncommon in modern house) might. There will be a tiny amount of heat from the cables and breakers inside which keeps it dry, but this is almost undetectable. A heavy continuous load like a tumble drier, storage heaters, or immersion heater does generate a little warmth in the CU, which you can sometimes detect on a cold day.

Is the consumer unit the circuit box thingy? It is on the external wall in a plastic box. He was worried about the steam/condensation basically getting the electrics wet.
The tumble dryer is only used a few times a week in colder weather as there is only the 2 of us.
So basically with a good extractor we should be ok?
Thanks

yes.

Is the plastic box on a wooden or mdf board, spaced off the wall, or is it straight on the plaster? A gap will help.

If you ever see visible condensation forming on, or dripping from, the CU, think again. They will withstand a bit of steam, but are not intended to get wet.

a modern plastic CU

Yes it is on a board. I think we will give it a go but keep an eye on it.
Thanks for your help :-)
