The energy saver’s calendar

You can reduce your energy consumption throughout the year by, for example, choosing electricity produced with renewable energy, avoiding creating food waste, and turning off appliances and lights when you don’t need them. The energy-saver’s calendar is here to remind you of different energy-saving measures to take throughout the year. Check out the energy saver’s calendar for tips on energy efficiency!


In January, it is worth cleaning the refrigeration equipment and defrosting the freezer, as you can temporarily store the frozen food outside. Vacuum the backs of the refrigeration equipment and make sure that air circulates around them. Set the correct storage temperatures: +2–6 Celsius for the refrigerator and -18 Celsius for the freezer.

Remember that the car heats up within two hours even in severe frost!


Avoid using an air source heat pump during the most severe frosts. An air source heat pump produces only the same amount of heat in severe frost as it consumes electricity. Turn off the air source heat pump when the temperature gets down to about -20 degrees. Restart the pump when the temperature has warmed to about -15 degrees.


Adjust the temperature of the domestic water to 58 degrees. Overheating is an unnecessary expense, but remember that at too low a temperature there is a risk of Legionella bacteria.


Wash the windows. Dust and dirt prevent the sun’s rays from shining through the window. By washing the windows, you let the spring sun in to provide heat and bring light inside.

Check the adjustments of the ventilation unit. It is not worth heating the supply air unnecessarily when the weather warms up.


Let the spring breeze dry your laundry. The most energy-efficient way to dry the laundry is to take it outside to dry. As a bonus, the clothes will smell fresh and won’t wear out, as in tumble drying.


Ensure good ventilation. Clean the supply air filters and the ventilation unit filters after the pollen season. If necessary, replace ventilators in poor condition with modern ones. Check that air can circulate in the rooms where the exhaust air ventilators or flues are located.

Adjust the comfort underfloor heating in the bathroom to a minimum.


Cool yourself off sensibly. Keep the heat outside by closing the blinds. Air out your home at night, not during the day. Mechanical cooling should only be used in moderation so that the electricity bill does not come as a surprise.


Let the autumn harvest cool off before freezing it. Don’t forget to turn the power freeze off!

Inspect the seals. Replace worn and leaking seals to avoid drafts and additional heating. Choose the seal thickness carefully—a seal that is too thick can break or hinder the closing of a window or door, and one that is too thin, in turn, will not plug a leak.


Illuminate energy-efficiently. Replace old incandescent and halogen light bulbs with energy-efficient LED light bulbs, compact fluorescent light bulbs, or eco-halogen light bulbs, depending on the application. Utilise timers, motion sensors, and light-sensitive switches for outdoor lighting.

Service and clean your ventilation unit before winter comes.


Prepare for the heating season. Adjust the heating system and monitor room temperatures. If you use a fireplace or an air source heat pump as a complementary heating system, adjust the thermostats on the radiators to a few degrees below the target temperature. If your ventilation system has it, turn on heat recovery. Enjoy the darkening evenings by candlelight.


Check the plumbing fixtures such as faucets, toilet seats, control valves, and pipe joints for leaks. If a replacement is relevant, choose water-saving plumbing fixtures. Flow limiters, aerators, and dual flush toilets reduce water consumption.

A comfortable room temperature is about 21 degrees. If you’re chilly, put on your woollen socks!
