-4c outside in the Toon.
Flat temperature dropped to 11c after sun down at around 3.30pm.
Manually switched on central heating at 7pm for 2 hours as it was just too cold. Auto timer is set from 6.30am to 7.30am & 7.30pm to 8.30pm but the heat loss rather fast today.
Now living room is 14.4c and bedroom temperature is at 8.7c because there is no insulation between the bedroom and the wall outside. Might sleep in the living room tonight.
It is going to be a freezing winter.
