In Helsinki’s Punavuori district, the sound of winter is not the polite hiss of radiators. It’s the low, patient crackle of a tiled masonry stove waking up at 6 a.m. Outside, the wind cuts across the Baltic and bites right through down jackets. Inside, a woman in wool socks opens a small iron door, feeds in two logs, and shuts it with a practiced hand.
The room is cool, not cold. There’s no rush. The heat will come, and when it does, it will stay for hours. Long after the flames die, the massive white stove in the corner will keep breathing warmth into the apartment.
Across Finland, energy experts are starting to admit something that sounds almost scandalous in a high-tech country.
Old-fashioned heat might be winning.
Why Finnish radiators are quietly being replaced by a centuries‑old trick
On paper, Finnish homes are a dream of modern efficiency. Triple glazing. Smart thermostats. Rows of neat, white radiators lined under the windows like soldiers. Yet talk to heating engineers from Turku to Oulu, and you’ll hear the same sentence again and again: the radiators are there, but the real comfort comes from the big thing in the corner.
That “big thing” is often a masonry heater or tulisija, a heavy wood‑burning stove built of brick, soapstone or tile. It looks like a piece of furniture, sometimes even like art. Families gather around it, kids lean their backs on it, dogs sleep at its base. And when the power prices spike, the tulisija just quietly does its job.
In the winter of 2022–2023, when electricity costs in Finland briefly went through the roof, sales of new masonry heaters and wood stoves jumped sharply. One manufacturer reported orders up by nearly 40%, and stove builders had waiting lists stretching into the next season.
People who had previously used their stoves “just for coziness” suddenly started relying on them as their primary heat source. In a suburb of Tampere, a family tracked their bills before and after switching to mostly wood‑based heating with their existing masonry stove. The result: their total winter heating cost was cut almost in half.
The surprise wasn’t that wood was cheaper. The surprise was how much *more* comfortable the house felt compared with cranked‑up radiators.
The secret is simple physics, not nostalgia. Radiators heat the air; masonry heaters heat the mass. A tulisija is built to absorb a huge burst of energy from a short, clean fire, store it in heavy stone, then release it slowly over 12 to 24 hours. That creates a stable, enveloping warmth that doesn’t vanish every time a door opens.

Experts point out that this kind of radiant heat warms objects, surfaces and bodies directly, so you feel comfortable at lower air temperatures. Less need to push the thermostat to 23°C just to stop shivering. That’s where the real savings show up, not only in energy bills but in how often the main heating system even needs to come on.
Radiators flick on and off all day. A good masonry stove works like a thermal battery.
The “low‑tech” routine that beats high‑tech heating
The core method Finnish energy specialists now quietly recommend sounds almost offensively simple. You run one or two hot, efficient fires per day in a properly built masonry stove, then let the mass do the rest. No constant tinkering. No turning valves every hour. Just a morning burn and sometimes an evening top‑up when it’s really cold.
Each burn lasts about 45–90 minutes, depending on the size of the stove and the outside temperature. The goal is a hot, fast fire with dry wood, lots of air, and bright flames. You’re not “babysitting” the fire all day. You start it, let it roar, then close the damper once the main embers are gone. The stove’s thick walls keep that heat and release it slowly.
One simple ritual. A whole day of comfortable rooms.
Many people who grew up with radiators make the same mistakes when they first try to rely on a stove. They burn too little wood, too slowly, then complain the house never really warms up. Or they treat the stove like a decorative fireplace, with occasional small fires that look nice but don’t charge the thermal mass.
There’s also the emotional barrier. We’ve all been there, that moment when you stare at a fire and think, “This can’t possibly heat a whole home better than my expensive system.” Yet Finnish case studies repeatedly show homes where the main electric or district heating system becomes a backup, not the star of the show. The numbers can feel almost embarrassing next to the marketing around “smart” heat pumps and connected radiators.
Let’s be honest: nobody really follows every automation rule their smart system recommends every single day.
Energy consultant Jari Hakanen, who has advised on retrofits across southern Finland, puts it bluntly.
“Radiators are fine, but they’re just one tool,” he says. “For steady comfort and long‑term costs, a well‑used masonry stove can outperform many modern systems, especially in older homes. The buildings were literally designed around them.”
He often gives homeowners the same checklist when they ask how to cut bills without sacrificing comfort:
- Use one large, hot burn in your masonry stove instead of many small ones.
- Switch radiators to lower, stable settings instead of frequent temperature swings.
- Focus on dry firewood and good chimney draft to keep burns clean.
- Sleep with slightly cooler air, relying on the stove’s radiant warmth in living spaces.
- Combine stove heat with a simple fan to spread warmth room‑to‑room.
*The pattern is always the same: those who commit to the routine quickly stop worrying about every little radiator setting.*
What this quiet Finnish shift says about the future of home heat
It’s tempting to see the Finnish love for masonry stoves as a charming northern quirk, like ice swimming or coffee at all hours. Yet the trend carries a broader message that goes far beyond the forests of Karelia or the streets of Espoo. As energy prices stay unpredictable and grids come under pressure, countries that once rushed to cover every wall with radiators are suddenly reconsidering what “modern” should mean.
The Finnish lesson is not that everyone should rip out their radiators and start chopping wood. It’s that combining high‑tech systems with surprisingly old ideas can unlock a kind of comfort‑per‑euro most people have never really experienced. A steady, quiet warm that radiates from a single point, instead of the twitchy on‑off pulse of hot water pipes.
For many Finns, the radiator isn’t exactly dead. It’s just been demoted.
| Key point | Detail | Value for the reader |
|---|---|---|
| Radiant mass beats hot air | Masonry stoves store heat and release it slowly over many hours | More stable comfort with less energy use than constantly cycling radiators |
| Simple routine, big savings | One or two efficient daily burns can cover most heating needs in many Finnish homes | Clear, realistic habit that can cut bills without complex tech |
| Hybrid setups win | Radiators stay as backup while stoves do most of the work | Flexibility during price spikes and power cuts, not just in Finland but anywhere with cold winters |
FAQ:
- Are Finnish radiators really becoming obsolete?Not overnight, but many experts say their role is shrinking. In homes with masonry stoves or similar systems, radiators often end up as backup or for specific rooms rather than the primary heat source.
- Is wood heating actually cheaper than modern systems?When wood is locally sourced and burned efficiently in a high‑mass stove, it can be significantly cheaper per kilowatt‑hour than electricity or district heating, especially during price spikes.
- What about emissions and air quality?Old, smoky fireplaces are a problem, but modern Finnish masonry heaters are designed for hot, clean burns. Dry wood, proper use and regular maintenance are crucial for keeping emissions low.
- Can this kind of system work outside Finland?Yes, similar stoves are common in other cold countries like Sweden, Norway, Germany and Austria. The key is building or retrofitting a proper high‑mass heater rather than relying on a thin metal stove alone.
- Do I need to get rid of my radiators to benefit?No. Many Finns use a hybrid setup where radiators stay in place at lower settings while a masonry stove carries most of the load, combining comfort, resilience and cost control.
