Should I keep the heating on all day?

Q: We own quite a large old stone house and each winter we have the same discussion! Should we leave the oil heating turning over at a low temperature (we like a cool temp of around 18) or use it during 2 or 3 periods of the day? The same for underfloor electric heating in the bathroom?
A: Generally speaking, for a lower temperature heating system, it is more efficient to leave the heating on continuously, and for a higher temperature system it is more efficient to turn it on around key demand periods.
Heat loss from a building is proportional to the difference in temperature inside and out. The more airtight and well-insulated your building, the less important this becomes. This explains why in well-insulated buildings using low-temperature heating (for example many houses in Scandinavia) it becomes efficient to leave heating on 24 hours a day.
There is no hard and fast rule. It will depend on how you use the house and your comfort. If you are in all day, then you may well choose a different option than if you are out at work all day.
