hi, i currently set my central heating to come on in the morning and evening, but have just installed a programmable thermostat which allows me to select different temps for different times of the day.
Is it better to have the heating 'on' but at a slightly lower temp settting during the day when i'm out, and overnight, or is it more economical just to have it switch on a bit before i get up, and just before get home from work.
someone told me it is more economical to have the heating on constantly, but couldn't explain whiy...is this true and why??
Thanks,
Paul
