My boiler has taken to staying on for fifteen minutes and then cutting out. I had FIRST Plumbing & Heating GOC Ltd round to look at it twice to no avail. The first time they serviced it and decided there must be a blockage. The second time they cleaned out the F&E tank and flushed through with chemicals. Still no dice and I haven't heard back from then since. Been trying Plan C Today. Running the heating and the hot water manually via the Hive web interface for seven minutes then turning them off for eight. Rinse and repeat.
What I will do I think for the meantime is program the system to follow that schedule automatically. It looks a bit long winded on the UI though. I wonder if there is an API or something I can use to get at it more directly?
Also, not to self, try draining the radiators.
