I need a mains powered wireless thermostat

[ProDave]

New build house, all plasterboarded and painted.

Customer has just discovered nobody had put the central heating thermostat on the plans and he didn't spot it's omission at first fix.

Simple I thought a wireless thermostat.

But I can't find one that doesn't use batteries?

All I want it the thermostat bit, mains powered, that can go close to a light switch and pick up power from that (loop at switch) and the receiver in the cupboard with the boiler.

but I just can't find one where the thermostat end is not battery powered, and he doesn't want to keep replacing batteries.

Short of butchering one and burying a small power supply in the wall?  Can anyone find a mains powered one?

Does he know the batteries will last a couple of years, l have had mine for 4 or 5 years now and it is only on its 2nd set of batteries.  Sounds more hassle than it's worth Dave.

The amount of doddery old dears I've been to with flat batteries in their stats It would be a good ideA to have a mains one.

We don't charge for this sort of thing at least I think we don't, it's a plumbers job and I am not a plumber so I don't charge but If they called out another firm that would be £90+vat to change some batteries.

Nice work If you can get it!

Ah, the devil is in the detail, Its a part of our contract with the council.  

Basically not ripping off old Lady's for simple jobs.

Nest... but you would have to use the supplied power lead and adaptor. Could you install it backing on to a cupboard somewhere and plug it in within the cupboard?

Most wireless thermostats have a low battery indicator and don't just go dead over night...and as said above last at least a couple of years.

Danfoss TPOne range? They do it in 230V or battery powered.

Doesn't that still require a cable between the contact on the thermostat and boiler though?

Can't search ATM, but could you use a normal wired roomstat and connect the heat-on/off to a separate radio (light)switch to switch the boiler on/off? if that makes sense.
