We have the above boiler and have tried to fit a Nest thermo via a "pro" (confirmed gas safe engineer).
In short, the only way to make it work properly without the pump going 24/7 is by removing the timer/display module from the boiler. I did speak to Worcester who simply said the boiler isnt suitable for any external controller including their own offerings and wouldnt comment on any consequences of removing the timer.
I know by doing so a) I lose the timer facility for hot water and so it acts as a basic combi-boiler and b) fault diagnosis may be more difficult without the screen but is anyone aware of any other issues from doing this?
