The chart below shows a 6 month record of daily minimum temperatures (dotted lines) and daily maximum temperatures (solid lines). During winter 2010-2011, the outside temperatures were pretty low.
The boiler in the outhouse had a self-protection mechanism that switched it on at very low temperatures. This meant that the heating was on day and night during very cold weather, with the house thermostat in the hall set at a minimum of 10 degrees C.
Sadly we didn't have any dataloggers in February 2010 when the boiler broke down for 2 weeks leaving us with no heating or hot water. Suffice to say, it was chilly - my children (a baby and a toddler at the time) were dressed in so many layers they could hardly move!
Temperatures in the kitchen are higher than in the hall due to cooking (as you can probably guess from the chart, we were away over Christmas). Neither room ever felt truly comfortable in cold weather due to the temperature fluctuations experienced (across the rooms, and over time). Even with room temperatures generally above 10 degrees C, ice on the inside of some windows was a regular occurrence on cold mornings.
