I'm soon going to be moving into a new (to me) flat that has a new
combi boiler with an old fashioned wired thermostat. The timer is
mounted on the front of the boiler and is a very crude mechanical

Part of me wants to install a Hive system but as a halfway house I'm
wondering about about replacing the basic thermostat with a digital
one - then I could leave the boiler on constant and set some fancy
varying programs via the thermostat - different times and
temperatures on different days.

So basically a standard programmable thermostat then...

Does my proposed setup and sound practical and can anyone recommend a
stat please?

Yup eminently doable. I quite like the Horstman Centaurstat 7. It gives
several time slots per day (up to 6 IIRC) and all 7 days are
programmable independently if you want (or you can copy one day's
settings to any other, or do basic 5+2 day programs)


What about Hot Water - will you leave that on timer - or have a cylinder
thermostat?

The OP mentioned a combi boiler, so that is heated on deamnd.

However if you have stored hot water, then you will need a more
conventional programmer and cylinder stat for that bit.



Unless to go for something like Hive which - if you buy the right model
- can do both. [You still need a cylinder stat, though].
