Energy monitoring service

Use our energy monitoring service to check your electricity consumption per year, month, week, day or hour. The service will help you to find out where you use electricity at home, and how you have managed to save it.

Electricity consumption data is updated in the system on the next day. You can for instance enter details about a new air source heat pump or domestic appliance and see how the changes affect your electricity use.

The electricity reporting service is free to use and available in Finnish, Swedish and English. You can access the service any time you like.

Energy saving tips

How to save electricity at home

It is easy to reduce household electricity consumption by changing your own actions. Even small changes can bring great savings. Check out our savings tips below!

Save on heating and ventilation

You can save energy by lowering room temperatures, sealing windows and doors, and ventilating quickly with crossover. Lowering room temperature by one degree can save you up to five percent on heating costs.

Electricity savings tips for heating

Direct electric heating

Check if the thermostat works. The old mechanical thermostat may slow down and react slowly to temperature changes, whereby room temperature may vary a lot, and due to that electricity consumption increases.

Oil, pellet, wood chips and wood heating

When the fuel runs out, heating is usually transferred to electric resistances. Also, the burner bar or blockages in the heater may trigger electrical resistances. Make sure that there is sufficient fuel and maintain the heater at regular intervals, so that its power does not deteriorate.

Heat pumps

You can save energy with a suitable heat pump placed in the right spot. It is also important to remember regular maintenance of the heat pump, such as replacing the filter and adjusting settings.

Proper dimensioning is needed if you want your geothermal pump to function with maximum efficiency. If your geothermal pump is subdivided, part of the heat is generated using other heating mode, for example electric resistor. In a full-scale geothermal heat pump, the heat is produced entirely by geothermal heat, but it is possible that the toughest freezing will turn on in the toughest freezing temperatures.

More information on heat pumps is available at Suomen Lämpöpumppuyhdistys' and Motiva's website.

Underfloor heating

A suitable floor heating temperature is from 20 to 24 degrees. Underfloor heating is not intended to heat the entire bathroom, but to make the floor surface slightly warm. You can check the surface temperature of the floor with a surface thermometer.

Mechanical intake and exhaust air exchange

In the summer it is advisable to turn off the post- and preheating of the mechanical intake and exhaust air. For it to operate efficiently, the ventilation unit should be serviced at regular intervals.

Other electricity saving tips for your home

Refrigerator and freezer

Refrigerators consume majority of the energy in the kitchen, but simple measures can reduce their consumption by up to one third.

  • Place the refrigeration appliances away from heat sources such as radiators and stove.
  • Freeze the freezer regularly and check the condition of the seals.
  • Consider replacing your old refrigerator with new more energy-efficient one.


With a traditional electric sauna stove, preheating consumes about half of the electricity it takes to heat the sauna. The best thing to do therefore is to heat the sauna for many people at once instead of heating it more frequently for just a few people.

If you take a sauna every or almost every day, an instantly ready sauna stove is a good option. It retains constant heat in the stones, and its electricity consumption is from 2,000 to 3,000 kWh per year. With instantly ready sauna stoves, the condition of seals should be regularly checked because worn out seals increase the electricity consumption required for keeping the stove always ready.

Domestic hot water

Hot domestic water forms a large proportion of the energy consumption of a household. Managing your hot water use can have a significant effect on your cost of living.

Home electronics

A large proportion of the energy consumption of televisions, computers and other home electronics is from when the devices are on standby. Throughout their lifecycle, many devices end up consuming more electricity on standby than in actual use. There are 8,760 hours in a year, and a constant consumption of one watt means about one euro in the electricity bill in a year. An extension cord equipped with a power switch is a handy option as you can easily turn off several devices at once.


The proportion of lighting in the electricity consumption of Finnish households is about one fifth when heating is not taken into account. The best advice for cutting down the consumption of lighting is very simple: turn off unnecessary lights.

Average consumption of electrical devices

How to calculate the consumption of electrical devices

You can calculate the consumption of an electrical device when you know the device's power (watt, W). Before calculating the consumption, you should always convert the device's nominal power into kilowatts (1,000 watts = 1 kilowatt) and the time the device is used into hours (30 minutes = 0.5 hours). You can calculate the device's energy consumption (kWh) by multiplying the device's power (kW) with the time it is in use (h).

Example: Vacuuming takes 1.5 hours in your weekly cleaning. The power of the vacuum cleaner is 1 kW. The consumption is 1.5 kWh.
