Advice re installing ESI Single Channel Multi Purpose Programmer

[diy_fun_uk]

The existing programmer is faulty and requires to be replaced. Model ESI 1 24/7. Controls electric heating only, not the hot water. See image below for the setup. Now discontinued I think, from what I can determine the direct replacement is as per the link below.

How straightforward a job to replace old for new? My electrical skills extend to wiring plugs, replacing light sockets, power sockets. What you can't see is behind the wall is a cupboard and on the wall is trunking with the cables to these items.

You say electric, so then big question is how much power goes through the thermostat? I would look at electric UFH thermostats, as most of them rated 16 amps, but it may be relayed anyway, so don't know what switch is required.

Lots have a universal/industry standard backplate, but Esi might need a wire moving, unless you go like for like?
