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.

    When installing the circuit into an existing consumer unit two spare ways are required, so the boiler supply MCB can be installed on the end of the row of MCBs with a void way to provide an air gap between it and the adjoining MCB to prevent the MCB overheating, as shown in the manufacturers instructions and as I did when I installed the supply to one of these boilers earlier this year.

    You also need a 3 amp supply for the controls which I did by running a SFCU off the boiler supply so the boiler isolator isolates both supplies to the boiler, again as per the instructions.
