Energy improvement potential
Recommended improvements for this property
Measures from this home’s official Energy Performance Certificate assessment that could raise its rating and cut running costs, specific to 91 SAPLING ROAD, BOLTON, BL3 3QQ.
- 1Floor insulation (suspended floor)Indicative cost: £5,000 - £10,000
Insulation of a floor will significantly reduce heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. Suspended floors can often be insulated from below. . Further information about floor insulation is available from many sources including www.energysavingtrust.org.uk/northernireland/Insulation/Floor-insulation.
- 2High heat retention storage heaters and dual immersion cylinderIndicative cost: £1,600 - £3,200
Modern storage heaters are less expensive to run than the direct acting, on-peak heating system in the property. A dual-rate electricity supply is required to provide the off-peak electricity that these heaters use; this is easily obtained by contacting the energy supplier. Ask for a quotation for high heat retention heaters with automatic charge and output controls. A dual-immersion cylinder, which can be installed at the same time, will provide cheaper hot water than the system currently installed. As installations should be in accordance with the national wiring standards, only a qualified electrician should carry out the installation. Ask a qualified electrical heating engineer to explain the options, which might also include switching to other forms of electric heating.
- 3Add additional 80 mm jacket to hot water cylinderIndicative cost: £20 - £40
Increasing the thickness of existing insulation by adding an 80 mm cylinder jacket around the hot water cylinder will help maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. The jacket should be fitted over the top of the existing foam insulation and over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness (or to suit the space available) for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast.
- 4Solar photovoltaic panels, 2.5 kWpIndicative cost: £8,000 - £10,000
A solar PV system is one which converts light directly into electricity via panels placed on the roof with no waste and no emissions. This electricity is used throughout the home in the same way as the electricity purchased from an energy supplier. The British Photovoltaic Association has up-to-date information on local installers who are qualified electricians. It is best to obtain advice from a qualified electrician. Ask the electrician to explain the options.
- 5Flat roof or sloping ceiling insulationIndicative cost: £900 - £1,200
Insulation of a flat roof or sloping ceiling will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Where the weatherproof membrane is sound and the roof construction is appropriate, suitable insulation can be placed on top of the roof membrane (inverted roof). Alternatively, where the weatherproof membrane needs to be replaced insulation can be provided under the weatherproof membrane (warm roof). Further information about roof insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).
