Updating your central heating system to save energy will have an impact on reducing your gas bills. Here are some suggestions to make your central heating system more energy efficient:
Have your boiler serviced annually. Regular maintenance to your boiler will help keep it running efficiently.
Fit Thermostatic Radiator Valves to all radiators. TRVs will provide control over the heat output of each individual radiator.
Change your circulating pump. Replacing your central heating pump to a new high efficiency A-rated model will help save energy.
Central heating system powerflush. Flushing out impurities, sludge and scale deposits is a good way to rejuvenate old central heating systems and help restore system efficiency.
Install an inline filter to the boiler. Inline magnetic filters protect the boiler by collecting impurities, sludge and scale deposits which hinder efficiency.
Upgrade your heating and hot water controls. Intelligent heating controls can be programmed to suit your routine and save energy when it is not needed.
Upgrade your hot water cylinder. Upgrade it to a new energy efficient unvented hot water cylinder or foam lagged cylinder.
Upgrade your old boiler to an A-rated condensing boiler.Many older boilers throughout the UK are G-rated and only a staggering 50% energy efficient. This means half the gas consumed by an old boiler is wasted.
By installing a new A-rated condensing boiler you may reduce your household heating bill by about a quarter, a saving, on average of £235 a year (Energy Saving Trust 2010)
Combine your boiler with renewable technologies. Solar thermal water heating or heat pumps can be easily integrated with a boiler installation. These will reduce your gas bill dramatically.
