Heating & cooling profile

HotAndCold's model combines the recorded floor area, property type and EPC data, so this 88m² 1970s semi-detached home has a current EPC rating of D64 and mains-gas heating. HotAndCold estimates a space-heating requirement of approximately 5.0–7.0kW. This property has moderate recorded energy efficiency, neither especially poor nor especially high. Its modelled space-heating intensity per square metre is relatively low.

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 39 LYSTER CLOSE, BIRCHWOOD, WARRINGTON, WA3 6QE.

  1. 1
    Solar water heatingIndicative cost: £4,000 - £6,000

    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
    Floor insulation (solid floor)Indicative cost: £4,000 - £6,000

    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.

  3. 3
    Replacement glazing unitsIndicative cost: £1,000 - £1,400

    Replacing existing double-glazed units with new high-performance units will improve comfort in the home and reduce energy use.

  4. 4
    Draught proof single-glazed windowsIndicative cost: £80 - £120

    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.

  5. 5
    Solar photovoltaic panels, 2.5 kWpIndicative cost: £5,000 - £8,000

    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.

  6. 6
    Flat roof insulationIndicative cost: £850 - £1,500

    Insulation of a flat roof 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).
