    Replacing mechanical stat with wireless programmable stat

    The plan is to set the existing timer to permanently on, therefore the live from the boiler will be permanent. Therefore can I connect my "live" wire to both the permanent live and common on the new receiver? The boiler is a Ferroli Falcon with a round digital 24hr programmer. Thanks.

    No of radiators on a spur

    I read somewhere on this forum that they suggest a maximum of 2.3kW per 10mm feed? Therefore 2 smaller radiators could run off one spur. My only problem with putting 3 sets of 10mm downpipes in is the connections to the main 22mm ring and whether these should be staggered by any distance? I do...
