Thanks for your help :D

That's great. Am I right in saying that Honeywell would be a good brand to go with here? How aboud Sunvic or one of the other brands?

Yes it's encased in polystyrene. Cutting away the insulation I can manage :) Can you clarify what you mean by saying I may need to fit a bypass valve? Is this so that the pump can still circulate the water after the various zones have switched off to avoid damaging the boiler? Would this...
