Boiler, programmer etc. via immersion heater circuit?

[RobMark]

Can I supply my central heating (programmer, two port valves and boiler) via a fused spur taken from the immersion heater circuit?

They’re currently supplied from a fused spur taken off the ring main; however, kitchen wall’s are being moved around.

There is nothing else on the immersion circuit (only the cylinder if boiler fails). The circuit is protected by a RTA061630B RCBO (see pic).

I took a look at the report. The summary is satisfactory with no C3. Item 4.18 is N/A, item 4.19 Pass.

Agreed 4.18 No SPD = N/A but surely 4.19 should be N/A too as no sign of an AFDD on the photo of the CU in #1. How can you 'Pass' something that isnt there? and yet omitted the fact that Fusebox RCBO's have been installed in another manufacturers board (see #3).

I was under the impression that 4.19 was a pass with ref to the three RCBOs that had been fitted. i.e RCD(s) provided for additional protection / requirements - includes RCBOs (411.3.3; 415.1).

I think it was, but didn't take note when I read it. Does appear to be akin to an MOT that required new brakes. Fit brakes (wrong size disc) and then test.
