Boiler running but thermostats off

Sabatinitennis · 18 Oct 2020

The three thermostats ...ground floor, first floor and next to the water tank on the cupboard on the first floor all turn off at 10.30pm. Yet green flame light was still on at 11.15pm and the boiler was quietly whirring away. Why is this?
