I have it. Was persuaded to buy with ‘free fitting’ when I had an engineer out to fix the boiler. At the time my system didn’t have a thermostat so it seemed like a good idea.
Not sure I’d recommend it.
The hive system currently only has 4 time periods that can be set with target temperatures. This is limited by the thermostat hardware.
There is also no ‘boost’ function. You can advance to the next period but cannot stick the heating on for, say, an extra hour.
The boost function was requested over a year ago when the system was introduced and there is no sign of it being rolled out.
For anyone wondering why a super-dooper thermostatically controlled system needs a boost, consider this scenario.
You have the heating ‘on’ until from 5pm to 11pm in the evening, with the overnight target temperature set to something low (so it is effectively off). You go out the pub or a club and get back during the overnight period. The house is a bit chilly so you’d like the heating on.
With hive, the lack of a ‘boost’ means you need to stick it on manual. You’ll likely fall asleep/pass out before remembering to turn it back to auto/schedule. You’ll be heating the house to 22+ degrees until breakfast time.
