12kW Electric Boiler.

Helllllooooo,

I have been asked to install new consumer unit for a couple as they are having a company supply and install a new 12kW Heatrae Sadia electric “boiler”. Has anyone any comments about such a beast. Any experiences of these please? Rather than supply it from a new consumer unit by a B50 M.C.B. I have considered supplying it from a dedicated switch fuse with a suitable H.R.C. cartridge fuse.

Thoughts anyone?

The makes are based in Norwich. Well I have only just learned that. I have no connection with Heatrae Sadia.

Then oversize the consumer unit to accommodate the flow boiler MCB and to allow for void ways to keep it cool or go down the two consumer units route.
The selection of the actual circuit cable is a minor matter, it’s the actual DNO intake and the customers consumer unit that need addressing first.
16 mm twin and earth is available as cut lengths from online suppliers, though I would try my usual wholesalers first.
Do not even consider rehashing the existing board.
Presumably the DNO supply is actually big enough to handle it?
