hi all,

Thanks in advance for having a look at this problem.

Long story short, we have just moved into a new house. Unfortunately it’s transpired that the shower pump is also connected to the switch for the immersion heater.

I'm not a morning person at the best of times, but having to get up 30mins earlier than normal to put the immersion heater/shower on before I get in is not ideal!

Has anyone ever seen this type of setup? Also, is there anything that can be down about the switch? Like some sort of Smart switch or timer??

Really appreciate any help.

Joe

P.s. I'll obviously get a qualified spark to do any work required :)

There are plenty of immersion timers out there from standard mechanical to WiFi types. There is nothing wrong with the set-up although your water heater switch seems to be connected back to front as the neon indicator is on when the switch appears to be off.

If that is the case then I would be worried about the whole house installation..........

A sparks could re-terminate that, so the shower pump could be switched independently from the immersion, as well.
 
May not even require the rcd spur. Dual box and matching accessories.

probably it's been connected wrongly. supply and load the wrong way round. shower pump should come from supply side. 10 minute job to fix.

From OSG
"Water heaters fitted to storage vessels in excess of 15l heating installation capacity, or permanently connected heating appliances forming part of a comprehensive space heating installation, should be supplied by their own circuits.
Immersion heaters should be supplied through a switched cord-outlet connection unit complying with BS1363-4."

agreed but tapping off 2A for a shower pump is not going to fry anything.

Which Regulation is that in BS7671.

Thanks for all replies! Very helpful indeed!

Few queries on this above but yes, it's an old house but new house for me (first time buyer).

I see that an immersion timer might be a good solution, would it just be a case of buying something like this:

https://www.amazon.co.uk/gp/product/B01E9R2SZO/ref=pe_4032721_311397401_em_1p_0_ti

Which would replace the switch (and RCD spur too??). Also, would this be ok to run shower pump and immersion from?

As above - I'd ask a spark to do any work required.

Cheers
 
The shower pump doesn't really need to be switched off and the rcd spur would only be unnecessary if you have rcd protection at the consumer unit.

Guess thats why the pervious 'spark' added a local RCD, i.e. no RCD protection at source?

@Joefarq1 could you add some pics of your fuseboard if your willing?
 
I would suspect that the previous owner/tenant left the immersion on constantly. If the tank is well insulated then its sometimes the better option than deep cycling every day.
