Energy Efficiency Tips for Winter 2025

There are lots of ways to make your home more efficient and comfortable and these energy tips might come in hand.

SEAI (Sustainable Energy Authority of Ireland) help us with some really useful tips to save energy, reduce energy consumption and save during Winter 2025. Here are some of them:

Temperature

Heating

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. You can reduce your heating bill by 10% by lowering your room temperature by just one degree.

Radiators

Use the radiator valve to turn the temperature down or off in rooms that you do not use a lot.

Hot water

Set your hot water thermostat to between 60-65°C, to make sure that you do not overheat your water.

Appliances

Most of the energy used by a dishwasher and washing machine is for water heating. Run them on a lower temperature setting and save on your energy costs. Wash clothes at 30°C if they aren’t particularly dirty.

Fridge freezer

Keep your fridge’s temperature at between 2-3°C for the best performance. This keeps your food safe to eat and avoids freezing (and ruining) your fruit and veg. The freezer should be set to -15°C.

Timers & Controls

Heating timers

Set the times that your heating comes on and off so that it fits with your daily routine. Radiators will continue to heat your home for some time after the heating is turned off. So try this, turn on your heating 30 minutes before you need it and turn it off 30 minutes before you don’t need it anymore.

Smart heating controls

Many homeowners are investing in smarter heating controls. These are often offered by their energy supplier. They control both time and temperature and are easily programmable to your daily and weekly routines all from your smartphone.

Hot water

An immersion timer can be really useful for ensuring you have hot water only when you need it. Then keep that hot water warm with insulation or a lagging jacket on the immersion.

Set your water heating to 65 degrees celsius on your immersion heating so that you don’t waste energy by overheating water.

Light

Windows

Maximise the use of daylight. Hold off switching on lights in the evening until absolutely necessary.

Layout

Position your furniture so you make the most of natural light.

Light bulbs

Replace failed light bulbs with energy efficient options, in particular LED lights. Select the lowest wattage bulb needed to light the room/area and consider the size of the space and how much natural light the space gets.

Turn off the lights

Remember to turn off the lights when you are leaving a room or where you do not need them.

Use sensors

Outdoor lights can be fitted with sensors and timers to reduce operating times.

Draughts

Listen to your mother

Close doors between rooms that are heated and unheated to keep the heat in.

Plug draughts

Check windows, keyholes and doors for draughts of cold air and plug them. Unused fireplace? A chimney balloon will keep the draughts out and the heat in.

Curtains

Close curtains to keep heat in, but open them in the morning to let the heat of the sun in.

Hot Water

Showers

A shower typically uses 20% of the energy compared to a full bath, so keep the bath as a treat.

Taps

Don’t leave the hot tap running - you are pouring energy and money down the drain.

Energy Monitors

Electricity monitors

These devices tell you how much energy you are using in real time. If you switch on the shower or the kettle, you can see the numbers jump. Monitors are great for getting a handle on where you use the most energy. You can make decisions on your energy use based on real data.
