According to leading energy experts at the Energy Saving Trust, as well as British Gas, the idea that it's cheaper to leave the heating on low all day is a myth. They're clear that you'll save energy, and therefore money, by only having the heating on when it's required. (Using a timer's best, because your thermostat is designed to turn your heating on and off to keep your home at the temperature you set it.) for thermostat upgrading and advice please get in touch.
The key thing to understand here is that it's all about the total amount of energy required to heat your home. It's a given that a certain amount of energy is constantly leaking out of your home (though exactly how much will depend on how good your insulation is). So the Energy Saving Trust says if you're keeping the heating on all day you're losing energy all day - and therefore it's better to heat your home only when you need it. However, it's not quite that clear-cut. Some specialists disagree – and argue you should keep the heating on constantly for an entirely different reason. They advocate keeping the heating on low all day, turning all radiator valves up to the max and the boiler down to the minimum, and say that the problem with turning the heating on and off is that every time it's turned off, condensation collects within the walls. This condensation can help conduct heat outside the home, they say – meaning you leak heat more quickly and so will use more energy as a result. If you have an old boiler the old non condensing type renewing you boiler to an A rated unit which uses all fuel as nearly all the heat produced is used to heat your home.
We recently installed a Worcester External condensing Oil Boiler to a property in Templeton, Pembrokshire to replace there twenty year old boiler which had broken down and was beyond repair. Our customer has since reported a reduction in oil consumption. If you require advise about boiler installation please contact us, we cover all of Carmarthenshire, Pembrokeshire and Ceredigion.
