And happy September to you Mr Oaf
I believe outside temp was below 10 last night. CH is set to be on 24/7 with a thermostat set at 20 in the day and 16 at night. I guess it got below 20 overnight so kicked in at 7am, first time it's been active for months. If that makes me a "great big tart" then so be it.
