Heating & cooling profile

HotAndCold's model combines the recorded floor area, property type and EPC data, so this 92m² 1970s end-terrace home has a current EPC rating of E40 and its recorded heating. HotAndCold estimates a space-heating requirement of approximately 5.5–7.0kW. Its current energy rating indicates relatively weak energy performance compared with more efficient homes. 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 21 SOUTHDOWN CLOSE, HEATON NORRIS, STOCKPORT, SK4 1LB.

  1. 1
    Insulate hot water cylinder with 80 mm jacketIndicative cost: £15 - £30

    Installing an 80 mm thick cylinder jacket around the hot water cylinder will help to maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. A cylinder jacket is a layer of insulation that is fitted around the hot water cylinder. The jacket should be fitted 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.

  2. 2
    Low energy lighting for all fixed outletsIndicative cost: £20

    Replacement of traditional light bulbs with energy saving recommended ones will reduce lighting costs over the lifetime of the bulb, and they last up to 12 times longer than ordinary light bulbs. Also consider selecting low energy light fittings when redecorating; contact the Lighting Association for your nearest stockist of Domestic Energy Efficient Lighting Scheme fittings.

  3. 3
    Floor insulationIndicative cost: £800 - £1,200

    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 sometimes be insulated from below which means that the floor does not need to be lifted to install the insulation. Further information about floor insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).

  4. 4
    Solar photovoltaic panels, 2.5 kWpIndicative cost: £9,000 - £14,000

    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.

  5. 5
    Fan assisted storage heaters and dual immersion cylinderIndicative cost: £1,200 - £1,600

    Modern storage heaters are smaller and easier to control than the older type in the property. Ask for a quotation for new, fan-assisted heaters with automatic charge control. 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 current regulations covering electrical wiring, only a qualified electrician should carry out the installation. It is best to obtain advice from a qualified heating engineer. Ask the engineer to explain the options, which might also include switching to other forms of electric heating.

  6. 6
    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.

  7. 7
    Cavity wall insulationIndicative cost: £500 - £1,500

    Cavity wall insulation, to fill the gap between the inner and outer layers of external walls with an insulating material, reduces heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. The insulation material is pumped into the gap through small holes that are drilled into the outer walls, and the holes are made good afterwards. As specialist machinery is used to fill the cavity, a professional installation company should carry out this work, and they should carry out a thorough survey before commencing work to ensure that this type of insulation is suitable for this home. They should also provide a guarantee for the work and handle any building control issues. Further information about cavity wall insulation and details of local installers can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).
