The best way to cure this permanently is to run a wire from the boiler to a thermostat location. Is this possible?
Customer: replied 4 years ago.

Yes, this can be done. It would be from the kitchen to the hall.

Expert:  Andrew Smith replied 4 years ago.
This would be a much more reliable way.
You need to run a 3 core cable from the boiler and wire into the thermostat contacts.
Do you have one in mind?

Dear Andrew,

After looking at the options I think a combination of a Siemens RWB27 programmer and a Siemens RAA20-GB standard room thermostat might work. Is this a good set up with a EHC Ecosave 37K Gas fired wall mounted condensing combination boiler?

That would work,you just need to check the wiring before turning back on again.
