12kW Electric Boiler.

Zoomup

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.

    If you put in a set of Henleys and a switch-fuse (which seems to be an excellent solution) the existing CU will be none of your business.

    Indeed. My estimate offers two options. 1. A new 60 Amp switch fuse only, and 2. A new 60 Amp switch fuse and new consumer unit. I don't really want a solid 50 Amp continuous load running from a modern consumer unit. I bet that confused the customers as option 1 is obviously less in cost, and the “boiler” installers said that the customers needed a new consumer unit. So, that ball is in the customers' court.
