Replacement for Manual Thermostat

[greyam100]

Hi,
The underfloor heating (hot water system, 1st generation) in our sunroom is currently operated solely by a manual wall mounted thermostat which works fine but can anyone suggest

a) a simple replacement thermostat with a timer on it (digital)
b) whether it is fairly easily replaced by myself who can do basic diy electrics, changing lights etc.

The underfloor heating is heated by the central heating boiler, but only when the thermostat calls for it. The main house central heating is on a wall mounted timer but the underfloor heating is independent from it.

Photos of current underfloor heating thermostat are here....

Thanks in advance

Heatmiser stat should do the job. You need to determine which one from the range you'd require.
