SEAI issues ten tips to help you save money while staying warm this winter

With a cold spell expected this weekend, the Sustainable Energy Authority has given its ten top tips to save money while staying warm this winter.

"Reducing the amount of energy you use in your home saves you money, lowers your carbon footprint and contributes to a cleaner, healthier environment," it said.

Here are its top ten tips:

  • 20 degrees Celsius is an ideal temperature for the living areas in a home. Lowering your thermostat by just 1ºC could knock up to 10% off your heating bill, saving around €150 in a typical family home.
  • Get your boiler serviced annually to ensure safe and efficient operation. It could save you a further €150, which should cover the costs.
  • Use the 30-minute rule in cold weather: In the morning, set your heating to come on 30 minutes before you wake up and go off 30 minutes before you leave for work. In the evening set it to come on for 30 minutes before you are due home and off 30 minutes before you go to bed.
  • If only one room needs heating, such as a home office, use a space or portable heater instead of the central heating. For free standing heaters, choose ones with thermostat controls and timers for more efficient heating.
  • While open fires look beautiful, they are a real waste of energy with more than 75% of energy going up the chimney. They are also damaging to air quality, so choose a more energy efficient option.
  • Don’t overheat unused rooms. If they are going to be unoccupied for long periods, turn down the thermostat or valve on the radiators but keep a small trickle of heating going. This will help to reduce the risk of condensation.

  • If you are leaving the house unoccupied for an extended period, set the timer and thermostat to allow for a low level of heating each day. This will help to reduce the risk of frost damage.
  • Much of the heat loss from a house goes through the windows, particularly if they are single-glazed. Keep curtains closed at night and ensure they hang behind radiators.
  • Insulating your attic and wallscould save you 30-40% on your home heating bill. Grants for wall and roof insulation, as well as home heating upgrades, are available from SEAI with quick online approval available. Visit
  • Remote heating controls allow you to turn on and off your heating from your phone, tablet or computer and are really useful if you work irregular hours.
