Switzerland consumes around 230 terawatt-hours (TWh) of final energy per year. Nearly half — about 100 TWh — goes to buildings. And the single largest item inside those buildings? Space heating. If you want to meaningfully reduce energy consumption in Switzerland, heating is where you have to start. This article breaks down the numbers, compares heating systems by actual consumption, and explains why zone heating with infrared panels can cut total consumption more than most people expect.
Where Does the Energy Go? Swiss Consumption at a Glance
According to the Swiss Federal Office of Energy (SFOE), the country's final energy consumption breaks down into three main sectors:
- Buildings: ~45% — of which roughly 70% goes to space heating and hot water
- Transport: ~35% — passenger cars, freight, rail
- Industry and services: ~20% — process heat, machinery, lighting
This means roughly one third of all Swiss energy consumption goes solely to heating homes, offices and commercial spaces. Switzerland has over 1.8 million buildings, and more than half are still heated with fossil fuels — heating oil and natural gas. According to the SFOE, that's around 900,000 oil boilers and 300,000 gas boilers, which together emit over 6 million tonnes of CO₂ per year.
Context: The Energy Strategy 2050 and the Climate Protection Act (KIG) in force since 2025 aim to gradually eliminate this fossil share. The heating sector is the single largest area of action.
Heating Energy by System: Who Uses How Much?
Not every heating system uses the same amount of energy for the same result. The table below shows the typical final energy consumption of various heating systems per square metre of living space per year — along with approximate annual costs for a 100 m² apartment at current Swiss prices (as of 2026).
| Heating System | kWh/m²/year | CHF/year (100 m²) | CO₂/year |
|---|---|---|---|
| Oil boiler (older building) | 150–180 | 1,650–2,500 | 3.9–4.7 t |
| Gas boiler (older building) | 120–150 | 1,440–2,250 | 2.8–3.5 t |
| Electric storage heater | 80–120 | 2,240–3,360 | 0.1–0.2 t* |
| Heat pump (COP 3.5) | 15–25 | 420–700 | ~0.03 t* |
| Infrared — whole-house heating | 60–80 | 1,680–2,240 | 0.08–0.1 t* |
| Infrared — zone heating | 30–50 | 840–1,400 | 0.04–0.06 t* |
* CO₂ figures based on the Swiss electricity mix (90% renewable/low-carbon). With a private solar system the figure drops to near zero. Prices: electricity CHF 0.28/kWh, heating oil CHF 0.11/kWh, natural gas CHF 0.12/kWh. Sources: SFOE, own calculations.
Honest note: Heat pumps have the lowest final energy consumption — they use ambient heat and need only a quarter of the energy of an oil boiler. As a whole-house heating system, they outperform infrared. The strength of infrared heating lies in zone heating: it heats only where you actually are. More on the honest limitations in our article Infrared heating pros and cons.
Why Zone Heating Cuts Consumption So Much
Most Swiss heating systems are central heating. They heat every room in the house, even when you're only sitting in the living room in the evening. In a typical 5-room apartment, only 2–3 rooms are used simultaneously on average — the rest is heated for nothing.
Infrared heaters work as decentralised zone heating. Each room has its own panel with its own WiFi thermostat. Unused rooms stay at a low base temperature (e.g. 16 °C), while actively used rooms reach a comfortable temperature within minutes.
Worked Example: 100 m² Apartment
- Central heating: All 100 m² heated to 21 °C → ~120 kWh/m²/year → 12,000 kWh total consumption
- Zone heating: 40 m² actively heated (living room, bedroom, office), 60 m² at 16 °C base → effectively ~50 kWh/m²/year → 5,000 kWh total consumption
- Saving: roughly 7,000 kWh or CHF 1,960/year in lower electricity costs
On top of this, there's the radiant heat effect: infrared panels warm walls, furniture and people directly — not the air. The human perception of warmth with radiant heat is comfortable at 1–2 °C lower room temperature. That translates to an additional saving of roughly 6–12% per degree less air temperature.
Summary: Zone heating + radiant heat can reduce heating energy consumption by 40–60% compared to central heating — not through more efficient energy conversion, but through more targeted use of heat.
The Swiss Electricity Mix: A Decisive Advantage
A common argument against electric heating: "Electricity is too expensive and too dirty." In Switzerland, the second argument doesn't hold up. The Swiss grid is roughly 90% low-carbon: the majority comes from hydropower (~60%), supplemented by nuclear (~30%) and a growing share of solar and wind energy.
This means every kWh of electricity you use for heating in Switzerland produces only a fraction of the CO₂ emissions of a kWh from heating oil or natural gas. And with a rooftop solar system, the carbon footprint of your heating drops to virtually zero.
Historical Trend: Switzerland Is Heating Less — But Not Little Enough
| Period | Development |
|---|---|
| 2000 | Building energy consumption at its peak. Over 60% of Swiss heating systems run on heating oil. |
| 2010 | Heat pumps gain market share. Building renovations increase thanks to cantonal subsidy programmes. |
| 2020 | Energy consumption per m² falls ~20% vs. 2000 — but growing total floor space keeps absolute consumption roughly stable. |
| 2025 | Climate Protection Act enters into force. Cantons implement MuKEn 2025: fossil heaters and electric heaters without self-generated power face phase-out timelines. |
| 2050 | Target: net-zero emissions. The entire building stock must be heated without fossil fuels. |
What Homeowners Can Do Now
Four practical measures that noticeably reduce the heating energy consumption of your building — ordered by effort and impact:
1. Adjust Heating Behaviour (free, immediate)
Lowering room temperature by 1 °C saves roughly 6% of heating energy. Keep unused rooms at 16–17 °C. Reduce the temperature at night. Simple, but effective.
2. Improve the Building Envelope (medium effort)
Windows, roof and basement ceiling are the largest sources of heat loss in older buildings. Replacing old windows with triple glazing alone can cut heating energy demand by 10–15%. Cantons offer subsidies for this through the Buildings Programme.
3. Switch Your Heating System (larger investment, biggest impact)
Switching from an oil boiler to a heat pump or infrared zone heating with solar reduces primary energy consumption by 60–80%. Depending on the canton, subsidies between CHF 5,000 and CHF 15,000 are available. Important: check the cantonal regulations on the electric heating phase-out — especially the solar exception.
4. Introduce Zone Heating with Infrared (quick retrofit)
Infrared panels can be installed without any building work — a power socket is all you need. Ideal for older buildings, holiday homes, or as a supplement to your existing heating. A single SunWave panel (250/350 W) heats a room of up to 25 m². Combined with a WiFi thermostat, it enables automatic zone control and scheduling.
Frequently Asked Questions
How much energy does Switzerland use for heating?
Around 45% of Switzerland's total final energy consumption goes to buildings. Of that, roughly 70% is used for space heating and hot water — about 100 TWh per year according to the Swiss Federal Office of Energy (SFOE). More than half of this still comes from fossil fuels (heating oil and natural gas).
Which heating system uses the least energy per square metre?
Heat pumps have the lowest final energy consumption per square metre: around 15–25 kWh/m² per year, because they extract heat from the environment (COP 3–4). Infrared panels in zone heating mode use 30–50 kWh/m², conventional electric heaters 80–120 kWh/m². Oil boilers require 130–180 kWh/m² of primary energy.
What does one kWh of heating energy cost in Switzerland?
The average Swiss electricity price is around CHF 0.28/kWh (2026). Heating oil costs approximately CHF 0.11–0.14/kWh and natural gas around CHF 0.12–0.15/kWh. A heat pump with COP 3.5 effectively costs about CHF 0.08/kWh of useful heat.
How can infrared heating reduce energy consumption?
Infrared heaters work as zone heating: they warm individual rooms on demand rather than heating the entire building. Unused rooms stay cool. This reduces actual heating energy consumption by 30–50% compared to central whole-house heating. Additionally, radiant heat warms walls and furniture directly, which improves perceived warmth at a lower air temperature.
Is the Swiss electricity grid clean enough for electric heating?
Yes. Around 90% of Swiss electricity comes from renewable or low-carbon sources — primarily hydropower and nuclear. An infrared heater running on Swiss grid electricity produces significantly less CO₂ per kWh of useful heat than an oil or gas boiler. Combined with a rooftop solar system, the carbon footprint drops to near zero.
What is the difference between final energy and primary energy?
Final energy is the amount that arrives at your home — the kWh on your electricity bill or the litres of oil in your tank. Primary energy also includes losses during extraction, transport and conversion. Heating oil has a primary energy factor of about 1.2, Swiss electricity about 1.5–2.0.
