Priority Switch for Electic Showers

Ezdezat

Hi All,

Just looking for some info on this if possible!

I have 2 x electric showers installed in my house (both Triton T90). I know this shouldn't be the case but we don't have a priority switch installed, the additional shower was put in by a friend who's an Electrician, he advised at the time that he shouldn't install it without, and that it would cost 2 or 300 € for the switch. We had the shower installed anyway and always ensure not to use both at once!

I'm now going to rent out the house, so i need to install the switch. Anyone know what sort of switch is required, what make / model?

Would this do the job?

Cheers!

that switch u linked to is not suitable ,one of these is what you need

there will be a bit of work for an electrician wiring it in

i that ebay link is the current sensing relay

so you'd also need a dp contactor to make up a priority controller


or alternatively you can buy the pre-made priority or non-priority unit in the meteor links


you'll need an electrician either way


(there's also the option of a 4-pole contactor and manual changeover-push switch or 2-way)

I have heard of many cases where priority units have failed.
That is why I have always gone for the contractor method described by M cebee.

one thing i don't understand is why instant showers don't have some sort of no-volt release

to prevent them coming back on again with these units or maybe other circumstances

I have never installed one of these, but my experience with Garo has always been negative. I simply do not rate them at all. Terminals are often too small and overall design of their products is poor IMHO.

not the best surely

schneider have a good rep but i see way too many of their rcbos sticking on commercial boards for my liking

hager may be one of the best

Not a bad idea at all. All it would need is an internal relay wired like a DOL with small start and stop bottons, to bring on the solenoid valve (and pump if applicable). Nothing more.

Thanks all for the info folks, at least i know now exactly what i'm looking for.
Like i said friend is an Electrician but he's not in the country at the minute, he did say they were reasonably expensive but thought that was it on Ebay.

Cheers again!
