Have you ever heard the Swedish word golvvärme? The meaning is underfloor heating, and it is essential for ensuring comfort in Swedish homes. It is no surprise that Swedes often ask, “Var kan man köpa bra golvvärme i Sverige?” (Where can you buy good underfloor heating in Sweden?). Another frequent consideration is, “Should I choose vattenburen golvvärme or elektrisk golvvärme?”, a question comparing water-based underfloor heating with electric underfloor heating. Each option has its own benefits, making the choice dependent on factors such as energy efficiency, installation costs, and the specific needs of your home. Understanding these distinctions can help you select the best solution for a warm and comfortable living space.
Comfort is one of the main reasons why underfloor heating has become a necessity in Swedish homes. Warm floors bring happiness to family members, creating a cosy and inviting atmosphere. Additionally, the design of typical underfloor heating, which conceals the heating source, enhances satisfaction by preserving the room’s aesthetic and interior concept. While underfloor heating is popular in many countries, the question remains: what is the best type of underfloor heating for Sweden?

Criteria for Underfloor Heating in Sweden
Heated floors significantly enhance comfort, making everyone in the room feel happier and more at ease. With various types of underfloor heating available, homeowners in Sweden have plenty of options to choose from, and they do not need to focus on just one type.
But what is the ideal type of underfloor heating? There is not a single definitive answer. Both hydronic underfloor heating (vattenburen golvvärme) and electric underfloor heating (elektrisk golvvärme) offer distinct benefits depending on the installation scenario and energy requirements. The type you choose depends on factors like energy efficiency, installation costs, and specific home needs.
Energy consumption is often a key consideration. Efficiency largely depends on the quality of insulation beneath the heating system and the materials used in the flooring. Ultimately, no single factor defines the perfect underfloor heating system. It is a combination of considerations tailored to each situation, especially in Sweden.
Hydronic and Electric Compared
Before looking at each type in detail, the table below sets out the practical differences that matter most in a Swedish context.
| Aspect | Vattenburen (Hydronic) | Elektrisk (Electric) |
|---|---|---|
| Best suited to | Whole-house and large areas | Bathrooms and small rooms |
| Installation cost | Higher | Lower |
| Running cost | Lower, especially with a heat pump | Higher over large areas |
| Heat-up speed | Slower, holds temperature longer | Fast |
| Floor build-up | Thicker, needs screed or panels | Thin, suits renovations |
| Renewable pairing | Heat pump, solar thermal, district heating | Only as efficient as the electricity supply |
What Are the Criteria for the Best Underfloor Heating?
Electrically Heated Floors
Electric underfloor heating is popular due to its simplicity and aesthetic appeal. The electric cable, hidden beneath the floor, provides a neat and efficient heating solution. While this type of heating is easy to install and heats up quickly, it tends to consume more energy compared to hydronic systems, because it converts electricity directly into heat at a ratio of one to one. This makes it ideal for small spaces like bathrooms or areas where precise, localised heating is needed. It can also be paired with hydronic systems for a hybrid approach across a house.
Hydronic (Water-Based) Floors
Hydronic systems circulate heated water through pipes installed beneath the floor. They are known for their energy efficiency, particularly in larger spaces or for whole-house heating. This type works well with renewable energy sources like heat pumps or solar panels, making it a sustainable choice. It also connects readily to district heating, which supplies a large share of Swedish homes, particularly in urban areas. While the installation cost is higher, the long-term energy savings often outweigh the initial investment.
The efficiency advantage comes from a specific technical relationship. A hydronic floor operates comfortably at a flow temperature of 30 to 45°C, and a heat pump becomes progressively more efficient the lower the water temperature it must produce. Pairing the two therefore multiplies the benefit: each unit of electricity the heat pump consumes delivers three to four units of heat into the floor, which is something electric heating cannot match by design.
Heating with Good Insulation
Proper insulation is critical to minimising energy loss. Swedish building practice sets high standards here, and substantial insulation beneath the pipes or cables, commonly around 300 mm in a slab-on-ground foundation, is normal rather than excessive. Without adequate insulation, heat escapes downward into the ground instead of rising into the room, reducing the system’s overall efficiency regardless of how good the heat source is.
Floor Types and Their Effects
The choice of flooring significantly impacts the efficiency of underfloor heating. Materials like tile, clinker brick, and stone are excellent at conducting heat and transfer it readily into the room. Wood and parquet, by contrast, have higher thermal resistance, which means they slow the transfer of heat upward into the space.
This does not increase heat loss into the ground, since downward loss is governed by the insulation beneath the pipes rather than the covering above them. What it does mean is that a wooden floor requires a higher water temperature to deliver the same heat output, and a higher flow temperature reduces the efficiency of a heat pump. If you plan to use wood or parquet, check the maximum surface temperature the flooring manufacturer permits, and factor the reduced output into the system design from the start.
Energy Consumption
To estimate energy consumption, consider how long the system will be used annually. While underfloor heating can reduce overall energy costs by maintaining steady room temperatures, careful planning is necessary. A floor temperature of 22 to 24°C is typically sufficient to achieve a comfortable room temperature of 20°C. For warm feet, slightly higher floor temperatures may be preferred, though this increases energy use.
Durability and Maintenance
Underfloor heating systems are long-lived, with hydronic pipework in particular capable of lasting several decades, often quoted at around 40 years or more. Repairs may require removing parts of the floor, which is why installation quality matters so much. Both hydronic and electric systems have long lifespans, but proper installation and maintenance are key to avoiding issues like leaks or electrical faults. In a hydronic system, the components most likely to need attention over that period are not the pipes themselves but the controls at the manifold, and those can be replaced without touching the floor.
What Is Typical Underfloor Heating in Sweden?
In Sweden, underfloor heating is often tailored to specific areas of the home. Ceramic floors, which feel cold during winter, are commonly paired with underfloor heating to enhance comfort. On the main floors of homes, hydronic systems with integrated water pipes are frequently used. These systems are efficient for larger spaces and connect seamlessly with central or district heating systems.
Bathrooms often use electric underfloor heating due to its quick installation and precise heating. Radiators are still commonly found on upper floors, where they operate at higher temperatures. This setup often requires multiple water loops to maintain efficiency across different heating zones.
Outdoor temperatures in Sweden can range from +5°C to -5°C during transitional seasons like spring and autumn. In winter, particularly in northern regions, temperatures drop considerably further. Efficient underfloor heating systems, equipped with room sensors and temperature controls, ensure consistent comfort regardless of the season.
The Components That Make It Work
A hydronic system depends on more than the heat source and the pipes. Warm water arrives at a manifold, which distributes it between the individual floor loops. On each loop, a thermal actuator opens or closes the valve according to demand, and a room thermostat in each zone sets the target temperature independently.
This zone control is what allows a bedroom to be held cooler than a living room, and it is where a meaningful share of the system’s efficiency is either gained or lost. A system with excellent pipes and a good heat pump will still waste energy if it heats every room to the same temperature regardless of use. The floor heating pipe itself should carry an oxygen barrier, which prevents oxygen diffusing through the pipe wall and corroding the metal components elsewhere in the circuit.
Your Trusted Partner in Underfloor Heating
Everyone can experience comfortable heating at home with energy-efficient solutions. Legom offers a complete range of products designed to meet Sweden’s underfloor heating needs, combining sustainability, durability, and performance.
Our air-source heat pumps are engineered for stable, efficient operation down to -35°C, which covers winter conditions across southern and central Sweden comfortably, including Stockholm, Gothenburg, and Malmö. In the far north, where temperatures can fall below that threshold during the coldest periods, a heat pump is typically specified alongside a supplementary heat source rather than as the sole provider, and district heating remains widespread in those regions for exactly this reason. Being clear about where the technology performs and where it needs support is more useful to a homeowner than an optimistic number.
Legom products go through rigorous processes to ensure long-lasting quality and performance, and the full component range covers manifolds, thermal actuators, room thermostats, floor heating pipe, and wax thermostatic elements alongside the heat pumps themselves. We proudly support your interior choices with the best heating solutions available. Be a part of our journey toward energy-efficient, cosy homes.
“Sweden is a market where customers already understand heating, which changes the conversation entirely. Nobody asks whether underfloor heating is worth it. They ask what flow temperature the system will run at, how the zones are controlled, and what happens on the coldest week of the year. That last question deserves an honest answer rather than a marketing one. Our units are rated to minus thirty-five degrees and that covers most of the country, but northern Sweden goes lower, and a homeowner in Kiruna is better served by a specification that acknowledges this than by a number that sounds impressive until the January it is tested.”

Frequently Asked Questions
Which is better in Sweden, vattenburen or elektrisk golvvärme?
It depends on the area being heated. Hydronic (vattenburen) underfloor heating is the better choice for whole-house heating and larger areas, because its running costs are substantially lower when connected to a heat pump or district heating. Electric (elektrisk) underfloor heating suits bathrooms and small rooms, where its fast heat-up and thin floor build-up outweigh the higher energy cost across a limited area. Many Swedish homes use both: hydronic on the main floors and electric in the bathroom. The decision is about matching each system to the space rather than choosing one for the whole property.
Does underfloor heating work in northern Sweden?
Yes, underfloor heating works anywhere, since it is a heat distribution system rather than a heat source. The question that matters in northern Sweden is what supplies the heat. An air-source heat pump rated to -35°C covers southern and central Sweden comfortably, but the far north experiences colder periods, so a heat pump there is usually specified alongside a supplementary heat source or replaced by district heating, which is widely available in Swedish towns. The underfloor system itself performs identically regardless of which of these feeds it.
What floor covering works best with underfloor heating?
Tile, clinker, and stone are the best performers because they conduct heat readily and transfer it efficiently into the room. Wood and parquet have higher thermal resistance, which means the system needs a higher water temperature to deliver the same output, and that in turn reduces heat pump efficiency. Wood can absolutely be used, but check the maximum surface temperature the flooring manufacturer allows and account for the reduced output when the system is designed. Thick carpet is the least suitable, as it insulates the room from the floor almost entirely.
How much insulation is needed under underfloor heating in Sweden?
Swedish practice specifies substantial insulation, commonly around 300 mm beneath a slab-on-ground foundation, which is high by international standards but appropriate given the climate. The purpose is to force heat upward into the room rather than allowing it to escape into the ground. This is one of the areas where cutting cost during construction produces a permanent penalty, since the insulation cannot be improved afterwards without removing the floor, whereas almost every other component in the system can be replaced later.
What temperature should the floor be set to?
A floor surface temperature of 22 to 24°C is generally sufficient to maintain a room at a comfortable 20°C. Some people prefer a slightly warmer floor underfoot, which is achievable but increases energy consumption. The water flow temperature feeding the system is a separate figure, typically 30 to 45°C for a hydronic floor, and keeping it at the lower end of that range improves heat pump efficiency considerably. Your floor covering also sets an upper limit, particularly with wood, so check the manufacturer’s maximum permitted surface temperature.
