[QUOTE="Ed-Wood, post: 554311, member: 37873"] OK, I'm now none the wiser on the 'x2 radials' idea but assume it's a no-go. So, back to my original scenario: a new ring circuit, 2.5mm t&e, c. 22m end to end, not running through any insulation, feeding only a 1.5kw water heater and a (let's say) 2kw underfloor heating system. Because the ceiling is down and I have the perfect opportunity to run the wires now, at negligible cost/effort (and for now putting aside all the issues regarding efficiency of the UFH etc). Any reason why not, from an electrical regs / safety point of view? What if UFH was 2.5kw? Did just read in the installation small-print for one make of water heater that it must not be on the same circuit as a fridge-freezer - no explanation given. So why would that be? Seems odd for a piece of kit primarily designed for a kitchen. [/QUOTE]
