A heat pump transforms free energy from the environment into heating and cooling. It consumes little electricity to move natural calories, which cuts your heating expenses by half or even two-thirds compared to a conventional boiler. You also gain energy independence and peace of mind throughout the year.
Why install a heat pump in Switzerland
The Swiss climate, with its cold winters and moderate summers, is perfectly suited to this type of system. Contrary to popular belief, a heat pump operates efficiently even in cold weather, especially high-performance air-air models and geothermal systems.
The concrete advantages are numerous:
- Reduction of heating bills by 50 to 70% depending on the model and building insulation
- Free cooling in summer with no significant additional cost
- Compatibility with solar panels for increased energy independence
- Lifespan of 15 to 20 years with minimal maintenance
- Eligibility for cantonal subsidies in French-speaking and German-speaking Switzerland
- No combustion, so no smoke duct or risk of carbon monoxide poisoning
The different types of heat pumps
The choice depends on your situation, your budget and your building.
Air-air heat pump
It's the most common model. The unit extracts calories from the ambient air, even cold air, and returns them indoors. A compact external unit is sufficient, and installation is quick compared to other systems. It's the ideal solution for apartments and small houses, or for light renovation.
Air-water heat pump
It heats the water in radiators or underfloor heating. It integrates into the existing system and can replace an old boiler without major work. The efficiency remains excellent, and comfort is identical to conventional heating. It's the preferred choice for complete home renovations.
Geothermal heat pump
It draws calories from the soil, where temperature is stable year-round. It's the most efficient and durable system, but it requires deep drilling or horizontal collectors. The initial investment is higher, but savings are maximum and reliability is exceptional. It's the reference solution for new construction and major renovations.
How a heat pump works
The principle is based on a simple thermodynamic cycle. A refrigerant fluid circulates in two circuits: one outside (where it absorbs calories), the other inside (where it returns them). A compressor, powered by electricity, transfers energy from a cold source to a hot source.
Efficiency is measured in COP (coefficient of performance). A COP of 3 means that for 1 kWh of electricity consumed, you recover 3 kWh of heat. Modern models display COPs of 3 to 5 under optimal conditions, far superior to the 0.9 of a conventional gas boiler.
Real savings on your bills
Figures vary depending on your region, current consumption and insulation quality. Here are approximate figures for Switzerland:
- Old house with gas boiler: savings of 1500 to 3000 francs per year depending on backup heating
- Well-insulated house: savings of 800 to 1500 francs per year
- Also enjoy air conditioning in summer at no significant additional cost
- Combined with solar panels: virtually free heating in summer and autumn
The payback of the initial surcharge compared to a conventional boiler generally takes 8 to 12 years, often less thanks to subsidies. After this period, it's pure gain.
Comfort all year round
Unlike traditional radiator heating, an air-air heat pump distributes soft, homogeneous heat. No cold drafts, no aggressive heating spikes. In winter, you maintain a stable temperature. In summer, cooling mode refreshes without drying the air.
Regulation is precise: programmable thermostat, smartphone remote control, adaptation to your schedule. You only heat occupied rooms, which increases savings.
Maintenance and serviceability
A heat pump requires little intervention. Annual filter maintenance and a service every 2 to 3 years are sufficient. Breakdowns are rare on quality equipment. WK Haustechnik in Bassersdorf offers professional follow-up to ensure your installation works properly and maximizes its lifespan.
Subsidies and assistance in Switzerland
Most French-speaking and German-speaking cantons support heat pump installations. Aid typically covers 20 to 50% of the investment. Check with your canton or municipality, or consult an installer who is familiar with the procedures.
Frequently asked questions
Does a heat pump work in severe cold.
Yes, modern models maintain good efficiency down to -15 °C. In very cold weather, electric or gas backup may kick in briefly, but the majority of heating is still provided by the pump.
What is the noise level of an air-air heat pump.
The external unit generates between 40 and 50 decibels, comparable to normal conversation at a distance. Proper installation and correct sizing reduce noise nuisance.
Can I install a heat pump in a small apartment.
Yes, an air-air heat pump fits easily on a balcony or small outdoor space. It's often the best option for small spaces.
