Heat it when you need it

With the clocks recently going back, it signalled the arrival of wintertime for many of us.

With that in mind, the SEAI has some great energy advice for homeowners to consider this winter ranging from simple lifestyle adjustments to more impactful home energy upgrades that will increase the comfort and efficiency of your home into the future.

Heat it when you need it

You can reduce your heating bill by ten per cent by simply lowering the thermostat by just one degree. Turn the thermostat for your living areas down to 20°C. The temperature in hallways and bedrooms should be cooler, ideally between 15-18°C. Once you’ve adjusted the thermostat, use timers to control the heating in your home. Set it to have your heating on at set times when you are at home and off when you are out. Use the control on your immersion heater to heat only your water when required. By using heating controls, you can save up to 20 per cent on your heating bill.


For long-term home comfort and to reduce energy bills, why not start planning your home energy upgrade now? This should be done in three steps. Following this process gives you the best results for your investment at every stage.

Step one

A Building Energy Rating or BER assessment is carried out by a SEAI registered assessor. The assessment now comes with a detailed advisory report, tailored to your home. The report will tell you what home energy upgrades your home needs to meet the modern standard for comfort and energy efficiency. The personalised report also sets out what supports are available to help fund the works, so you can decide which upgrades you want to carry out.

Step two

A home loses up to 30 per cent of its heat through the walls and 30 per cent through a poorly insulated attic. Investing in insulation will help to keep your valuable heat inside your home increasing your comfort and reducing your heating bills. If you complete this step, you will have a warmer home that is cheaper to run for many winters to come.

Step three

Adding renewable energy to your home will reduce your energy bills and support the move away from polluting fossil fuels. The most popular renewable systems are heat pumps, solar water heating panels and solar photovoltaic panels. You should always ensure your home is well insulated before considering installing renewable systems.
