A recent job has a combi boiler which is being swapped out for an ideal logic system boiler and tank. It's currently supplied by a 2.5t&e on a 6amp mcb. The boiler itself requires a local 3amp fuse. Which isn't s problem. But obviously now there's the tank to contend with.
Can I swap out the mcb for a 20A. Locally isolate the power and also "split" the local supply, one 3A for the boiler and a 13A for the tank? Or do I have to break it to them that I have to destroy some of their house to get a separate feed to the cupboard for the tank.
Cheers.
