Q. If I change my old boiler for a new one, how much can I expect to save?
A. If your boiler was installed prior to 2003, you could save a third on your heating bills and reduce your home's CO2 emissions by 800 kilograms a year.
Q. How much can I save by reducing my heating and water temperatures?
A. Reducing your room temperature by 1ºC could cut your heating bills by 10%. Setting your water cylinder temperature to less than 60ºC and fitting approved thermostatic mixing valves will also help save money.
Q. What is the ultimate low-carbon energy saving system that's available today?
A. Ground source heat pumps run almost entirely on non-fossil fuel. They extract the earth's natural heat using electricity that can be supplied by a renewable energy source such as solar power. The pumps have much lower running costs than oil, coal or electric heating systems and will cut your CO2 emissions by between 4.5 and 5.5 tonnes of CO2 a year.
Meanwhile, a solar water heating system can reduce CO2 emissions by 350 to 400 kilograms a year, depending on which fuel type it replaces.
