The frost will intensify towards the end of the week.
Now is a good time to check that the home is ready for frost and that the heating and ventilation are set up correctly.
Motiva gives tips on living in the cold in the press release:
1. Monitor the temperature, 20 to 22 degrees is appropriate
The feeling of cold is individual.
As a rule of thumb, however, it can be said that a suitable temperature in the living areas is 20 to 22 degrees.
In the bedroom, sweeter dreams come in degrees or pairs at lower temperatures.
Warehouses and garages, on the other hand, can be kept much cooler.
Temperature is also a housing health issue, commented Jussi-Pekka Krankkala, an Energy expert who previously specialized in energy management, to Ilta-Sanomat.
- Finnish homes have higher temperatures than the housing health recommendations.
In European comparison, we are at the top.
Therefore, it is advisable to monitor temperatures regularly throughout the winter and adjust the heating as needed.
- You will get a reliable measurement result when you place the meter on the partition of the room far enough from the windows and external walls, to a height of just over a meter, advises Motiva Oy's expert Teemu Kettunen in the press release.
Teemu Kettunen encourages the operation of thermostats by turning them from one extreme position to another.
Thick curtains and furniture should be moved away from the front of the radiators to allow heat to spread evenly throughout the room.
Old malfunctioning radiator thermostats and valves should be replaced with new ones.
There are also programmable smart thermostats on the market that can be used to set the radiator to aim for a different temperature at different times.
Setting a lower room temperature for the night can save on heating costs.
2. Save half by scheduling comfort underfloor heating

The most important function of comfort underfloor heating is to speed up the drying of the floor after a shower.
According to Helen, in comfort floor heating, the floor surface temperature is usually kept around 25-28 degrees and is not intended to heat the entire bathroom.
Scheduling bathroom comfort underfloor heating is smart for your wallet and environment, as it could increase your home’s electricity bill by as much as a couple dozen a month.
- Schedule comfort heating in the morning and evening at times when the space is being used and dried.
At best, you save up to half of the electricity used to heat your bathroom, Motivan Kettunen suggests.
However, remember to keep the ventilation of the washrooms running at all times.
3. Do not close the fresh air valves completely

The feeling of traction can be tempting to raise room temperatures above recommendations.
Before going to the thermostat, you should check the window seals and make sure that the fresh air valves in the supply air windows and other air valves are in the winter position, Kettunen reminds.
Do not close the fresh air valves completely, even in winter.
4. Check the settings of the ventilation unit
The feeling of draft may be caused by the temperature setting of the supply air post-heating resistor or heating water coil set too low, Motivan Kettunen says.
- The energy efficient temperature for the supply air is 16-17 degrees.
Too high a temperature can even mess up the operation of mechanical ventilation, so be careful.
It is a good idea to check that the heat recovery is on from the ventilation unit.
It is standard in detached house power class ventilation units installed at least in the 21st century, and in some older units as well, depending on the model.
Apartment buildings may also have an apartment-specific ventilation unit.
If the equipment is unfamiliar to the user, you should contact your service company for assistance.
Energy is also saved by adjusting the fan power.
- Maximum power is only needed when there are an exceptional number of people in the apartment, for example due to parties, cooking, sauna or even drying laundry.
For minimum power, you should adjust the device when you are not at home, Kettunen suggests.
5. Heat the fireplace proactively before frost
Electric heaters in particular should heat the fireplace proactively before the frosts intensify and continue heating during the cold period.
This will reduce the consumption spike caused by the cold cycle.

In the case of an hourly electricity contract, an additional benefit is that during the frost period, the hourly electricity prices can be higher than usual, which means that the savings brought by the use of the fireplace are also greater.
Checklist for home heating:
Check the operation of the heating system.
Adjust the thermostats and monitor the room temperatures.
The appropriate temperature in the living areas is 20-22 degrees.
Switch off any cooling setting and heat recovery from the ventilation unit.
Adjust the reheater to 16-17 degrees.
Turn the ventilation valves to the winter position, but do not close them completely.
Adjust the ventilation fan power as needed in everyday life.
Heat the fireplace in anticipation of frost.
