energy efficiency and the application of heating technology is poorly understood in this country...
1)its related to usage patterns... houses have people in them usually 16 hours of a day...but many have people in them 20 hours a day or more...for them on all day will be less wasteful.
2) its related to how you use the boiler...if the boiler is set up with compensation controls and the house is occupied say 16 hours or more it may well be more efficient to leave the heating on.
3) it depends on the level of insulation and the thermal inertia of the building...if you have to heat up a large thermal mass (which most houses are) twice a day then you will use more energy than leaving it running..or at least its marginal
its worth bearing in mind that all boilers accept compensation controls that match heat demand to heat generated...thus ensuring less wastage...
