Heating & cooling profile

HotAndCold's model combines the recorded floor area, property type and EPC data, so this 41m² end-terrace home has a current EPC rating of F33 and its recorded heating. HotAndCold estimates a space-heating requirement of approximately 3.5–4.5kW. Its current energy rating indicates relatively weak energy performance compared with more efficient homes. Its modelled space-heating intensity per square metre is moderate.

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 16 CASTLE ROAD, RUNCORN, WA7 2BE.

  1. 1
    Solar water heatingIndicative cost: £4,000 - £7,000

    A solar water heating panel, usually fixed to the roof, uses the sun to pre-heat the hot water supply. This will significantly reduce the demand on the heating system to provide hot water and hence save fuel and money. The Solar Trade Association has up-to-date information on local installers.

  2. 2
    High performance external doorsIndicative cost: £1,800 - £2,400

    High performance external doors contain insulation and lose heat at about half the rate of conventional external doors.

  3. 3
    Draught proof single-glazed windowsIndicative cost: £150 - £250

    Fitting draught proofing, strips of insulation around windows and doors, will improve the comfort in the home. A contractor can be employed but draught proofing can be installed by a competent DIY enthusiast.

  4. 4
    50 mm internal or external wall insulationIndicative cost: £7,500 - £11,000

    Solid wall insulation involves adding a layer of insulation to either the inside or the outside surface of the external walls, which reduces heat loss and lowers fuel bills. As it is more expensive than cavity wall insulation it is only recommended for walls without a cavity, or where for technical reasons a cavity cannot be filled. Internal insulation, known as dry-lining, is where a layer of insulation is fixed to the inside surface of external walls; this type of insulation is best applied when rooms require redecorating and can be installed by a competent DIY enthusiast. External solid wall insulation is the application of an insulant and a weather-protective finish to the outside of the wall. This may improve the look of the home, particularly where existing brickwork or rendering is poor, and will provide long-lasting weather protection. Further information can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).

  5. 5
    Floor insulation (solid 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. Further information about floor insulation is available from many sources including www.energysavingtrust.org.uk/northernireland/Insulation/Floor-insulation.

  6. 6
    Replace single glazed windows with low-E double glazed windowsIndicative cost: £4,500 - £6,000

    Double glazing is the term given to a system where two panes of glass are made up into a sealed unit. Replacing existing single-glazed windows with double-glazed windows will improve comfort in the home by reducing draughts and cold spots near windows. Double-glazed windows may also reduce noise, improve security and combat problems with condensation.

  7. 7
    Solar 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.

  8. 8
    High heat retention storage heatersIndicative cost: £800 - £1,600

    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. As installations should be in accordance with the national wiring standards, only a qualified electrician should carry out the installation. It is best to obtain advice from a qualified electrical heating engineer. Ask a qualified electrical heating engineer to explain the options, which might also include switching to other forms of electric heating.
