Hi all,
As some of you may know I'm installing gas central heating with the boiler in the loft. Things are progressing well, I've done all the pipework bar the last metre or so of the gas, and now I just have to finish off the wiring.
It's a standard Y-plan with the wiring centre in the airing cupboard. Thermostat in hall and programmer in the kitchen. The boiler is a Vaillant Ecotec plus 624 system boiler.
From the airing cupboard up to the loft I have run 2 * 1.5mm T+E, the first of which is the main feed to the boiler which is switched directly from a 3A switched spur, and the second feeds the programmer and all other associated switchgear, with the brown wire providing the live feed and the blue, the call for heat. This is as recommended by Vaillant - the idea being that if the boiler is switched off at the applicance, ALL other associated controls are no longer live.
So my question is how to I present these feeds to the boiler, in their existing T+E, or do I install a couple of accessories adjacent to the boiler and make the final run in flex? I am leaning towards flex, as the terminations at the boiler end are clearly designed to take flex, but essentially, I'm providing fixed wiring to a fixed appliance.
Assuming flex (and feel free to correct me) what accessories would I install? 1* unswitched socket for the boiler feed, and 1 * unfused flex outlet plate do you think? Or 2 * flex outlet plates? Any other suggestions?
I have put a photo here which shows the current wiring arrangements.
Thanks in advance.
