Heating & cooling profile

HotAndCold's model combines the recorded floor area, property type and EPC data, so this 75m² 1930s mid-terrace home has a current EPC rating of D56 and mains-gas heating. HotAndCold estimates a space-heating requirement of approximately 5.5–7.5kW. Its current energy rating indicates moderate energy efficiency. The estimated heat demand per square metre is around typical levels.

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 BROMPTON STREET, OLDHAM, OL4 1AF.

  1. 1
    50 mm internal or external wall insulationIndicative cost: £4,000 - £14,000

    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).

  2. 2
    Replace boiler with new condensing boilerIndicative cost: £2,200 - £3,000

    A condensing boiler is capable of much higher efficiencies than other types of boiler, meaning it will burn less fuel to heat this property. This improvement is most appropriate when the existing central heating boiler needs repair or replacement, but there may be exceptional circumstances making this impractical. Condensing boilers need a drain for the condensate which limits their location; remember this when considering remodelling the room containing the existing boiler even if the latter is to be retained for the time being (for example a kitchen makeover). It is best to obtain advice from a qualified heating engineer. Ask the engineer to explain the options.

  3. 3
    Upgrade heating controlsIndicative cost: £350 - £450

    A room thermostat will increase the efficiency of the heating system by enabling the boiler to switch off when no heat is required; this will reduce the amount of energy used and lower fuel bills. Thermostatic radiator valves should also be installed, to allow the temperature of each room to be controlled to suit individual needs, adding to comfort and reducing heating bills provided internal doors are kept closed. For example, they can be set to be warmer in the living room and bathroom than in the bedrooms. Ask a competent heating engineer to install thermostatic radiator valves and a fully pumped system with the pump and the boiler turned off by the room thermostat. Thermostatic radiator valves should be fitted to every radiator except for the radiator in the same room as the room thermostat. Remember the room thermostat is needed as well as the thermostatic radiator valves, to enable the boiler to switch off when no heat is required. It is best to obtain advice from a qualified heating engineer.

  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
    Flue gas heat recovery in conjunction with boilerIndicative cost: £900

    A flue gas heat recovery system extracts heat from the boiler flue gases and transfers it to the incoming cold water so that the boiler needs to supply less heat. It is suitable for use only with a modern condensing gas boiler and should be fitted when a replacement boiler is installed.

  6. 6
    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).
