Keeping your house warm

Keeping your house warm

Heat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection. For example, cold air can enter the house through gaps in doors and windows, and convection currents can transfer heat energy in the loft to the roof tiles. Heat energy also leaves the house by radiation through the walls, roof and windows.

Heat in your home is lost through:

  • Having no insulation in your loft, to avoid losing heat from your loft have it lined with insulation. This is a relatively easy process and not too expensive, and can reduce the heat loss through your roof space by almost 40%
  • Heat escapes out of windows.It is without doubt best to have double glazed windows, and also have good quality curtains up to keep heat in.
  • Having gaps around your doors and windows will let heat escape easily from your home. Fitting of adhesive draught excluders is again relatively easy and cheap to do and will seal the main part or all of the gaps.
  • Having cavity wall insulation filled in all your walls. Ensure your house is suitable for cavity wall insulation and that a proper pre-survey inspection is done and any remedial work is carried out to problematic areas prior to the installation.
  • Having carpet fitted on the floors also helps keep the heat in. Wherever possible, always use a quality underlay which will insulate at the same time as being comfortable.

Red areas on this thermal image show where the heat is most concentrated to escape from inside to the cold of the outside.

If you’ve had Cavity Wall Insulation fitted in the last 15 years, your walls could be having damp issues which may be showing signs such as damp and mould, and a lot of homes will not be so obvious that faults are lurking.
