I am not in the house enough to leave it on 2 long as in not letting the house cool down.
Gone at 8am leave it on for an hour before i go, about 3 hours in the eve, and add a few more hours to this for weekends..
I just dont feel that gas fired central heating gives anywhere near value for money.
If their was a new baby in the house the thing would have to be on alot more, id hate to see what the bills would be like then.
My brother has oil and i spend a fair bit of time in his house from what he tells me and from how long he leaves the oil on their seems to be a huge price difference in favour of oil..
Mercman ill try and get the price of the units from the bill at home to see if their is much of a diff with what ur's is coming in at..
