Electricity contract sähkölämmitykselle 2026
Direct electric heating is the heating method that consumes the most electricity in Finland - a typical detached house uses 15,000-25,000 kWh per year. The choice of electricity contract affects annual costs more than in any other use case: a difference of just one cent per kilowatt-hour means 150-250 euros a year. Picking the right contract is financially critical for households that heat with electricity.

Which electricity contract suits sähkölämmitykselle?
Spot price
Spot pricing offers the greatest saving potential for those who heat with electricity - typically 300-800 euros a year compared with a fixed contract. Smart control is almost essential so that consumption falls during the cheapest hours and price spikes do not catch you off guard.
Fixed electricity contract
A fixed contract is a safe choice if you want a predictable bill and do not wish to track hourly prices. At high consumption levels the peace of mind a fixed contract provides can be valuable - especially if you cannot time your consumption to cheaper hours.
Estimated annual cost - sähkölämmitys
The estimate is based on average consumption (20,000 kWh/yr). The spot-price estimate is based on a 12-month average price of 7.5 c/kWh (incl. VAT).

Saving tips - sähkölämmitys
- Install an air-source heat pump - it is the fastest way to reduce electric heating consumption by 30-50%
- Improve attic insulation - the greatest heat loss escapes through the roof
- Use smart thermostats that optimise heating based on the spot price
- Use the house's thermal mass: concrete structures store heat during cheap hours
- Lower the room temperature by 1-2 degrees - each degree saves about 5% on heating costs
- Seal windows and doors - even a small air leak significantly increases heating costs
Frequently asked questions
How much electricity does an electrically heated house consume?
A typical detached house of 120-150 m² with direct electric heating uses 18,000-25,000 kWh per year. A smaller or well-insulated house may manage on 15,000 kWh. In winter months consumption is 2,500-4,000 kWh per month, and in summer only 300-500 kWh.
Which electricity contract is the cheapest for electric heating?
Spot pricing with a low margin is usually the cheapest in the long run. At 20,000 kWh of consumption even a 0.5 cent difference in margin amounts to 100 euros a year. The most important thing is to compare total cost, not just margin or the monthly fee.
Is spot pricing a risk for someone who heats with electricity?
The risk is real but manageable. During severe cold spells the spot price can rise to 30-50 c/kWh, meaning an electricity bill of 30-60 euros in a single day. On an annual basis, however, spot pricing is almost always cheaper. Smart control helps manage the risk by shifting consumption to cheaper hours.
How can the costs of electric heating be reduced?
The most effective measures: 1) add an air-source heat pump (saving 30-50%), 2) improve insulation (10-20% saving), 3) lower the room temperature by 1-2 degrees (5-10% saving), 4) switch to spot pricing and time consumption to the cheapest hours. Combined, the saving can exceed 1,000 euros per year.
Is it worth switching from electric heating to ground source heat?
Ground source heat cuts electricity use by 50-70%, but the investment is 15,000-25,000 euros. The payback time is 5-10 years depending on the price of electricity. If the house will be owned for a long time, ground source heat is almost always a worthwhile investment. An intermediate option is an air-to-water heat pump (8,000-15,000 euros).
How does winter frost affect the electricity bill?
With electric heating, every additional degree of frost increases consumption by about 3-5%. When the outdoor temperature drops from -20 °C to -30 °C, daily consumption can rise to 80-120 kWh. At the same time the spot price is typically at its highest. This combination makes winter days expensive - but on an annual basis spot pricing is still usually cheaper.
