    So iv got to add a mini one UFH zone to an existing property's heating system, i have already wired in all the easy parts ie. actuator, zone valve, stat etc. however i just need to hook it up to trigger the boiler. iv attached a few images to try and explain things better, the plumber told me not to ring 'NU Heat' as he claims they are useless, however i rang them anyway and the technical help line stated that all i need to do is supply a permeant live to 'boiler enable in' and take 'boiler enable out' on to the switch wire of the boiler. (which iv drawn in pink below) which if this is the case its a piece of cake. however my main concern is will this work properly with the other 3 zones already in place. (ground floor ufh, Hot water, and upstairs rads) i was lead to believe in some situations a relay is required but the Nu heat tec doesn't seem to think this is needed, if anyone is able to cast an opinion on this would be great.

    More info The new 1 zone is for a kitchen extension, the wiring centre for it will be mounted in the kitchen cupboard where the manifold is, i was going to supply the L-N-E-SL directly from the outside boiler which backs onto the kitchen wall, and fit a triple pole switch in the cupboard. The SL from the new manifold will be doubled up inside the boiler with the existing SL.
