Hi - First Post so hello and thankyou in advance for any help/advice!
The undersink water heater has packed up in the kitchen, I'm guessing it's been there since the extension was done 20+yrs ago.
I recently plumbed in a new kitchen sink and it was all working fine for a few weeks. I live in SW London so the water is very hard - so I wouldn't be surprised if that was the issue. The existing setup is really straight forward with a power feed, cold water feed and hot water outlet. See pic attached of existing setup.
I've bought an Ariston 15 Lux as a replacement. I had assumed that I could just wire it up and connect the inlet & outlet pipework (15mm braided flexi). However a couple of queries;
1.) The existing electrical feed cable is probably not long enough so I will need to extend it. I've bought a cable jointing box so I can do this, but I don't know what size cable I need to use to extend it.
2.) The user manual talks about the need for an expansion tank? The existing setup doesn't have an expansion tank, so I'd assumed I wouldn't need this on the new system?
Any help on the above is much appreciated!
