The heat pump has established itself as the benchmark heating solution for modern properties in Switzerland. Efficient, environmentally friendly and increasingly subsidised, it is an advantageous replacement for oil and gas boilers. This complete guide explains how it works, the different types, real prices in 2026 and the support available in French-speaking Switzerland.

What is a heat pump?

A heat pump (HP) is a system that captures the heat naturally present in the environment — the air, the ground or water — and transfers it into your home. Its principle is remarkably efficient: for every 1 kWh of electricity consumed, it delivers 3 to 5 kWh of heat.

This ratio is called the coefficient of performance (COP). A COP of 4 means that the pump produces four times more energy than it consumes. This is what makes a heat pump far more economical than conventional electric heating or a fuel-fired boiler.

The different types of heat pump

There are three main families of heat pump, each suited to different situations:

Air-to-water heat pump

The most widespread type. It extracts heat from the outside air and transfers it to the heating circuit (radiators or underfloor heating) and to the domestic hot water. Simple to install and moderately priced, it suits the vast majority of villas. Its efficiency drops slightly in very cold weather but remains high in the Swiss climate.

Geothermal heat pump (ground-to-water)

It draws heat from the ground via vertical borehole probes. Very stable efficiency all year round, even in winter, because the ground temperature varies little at depth. The initial cost is higher (drilling is required), but performance and longevity are superior. Ideal for properties with land.

Water-to-water heat pump

It harnesses the heat of a groundwater table. Excellent efficiency, but it requires accessible groundwater and a specific permit. Rarer, and reserved for particular configurations.

Heat pump prices in 2026

The budget depends on the type of heat pump and the configuration of your property. Here are realistic ballpark figures for French-speaking Switzerland, before subsidies:

  • Air-to-water heat pump: CHF 25'000 to CHF 40'000 (equipment and installation)
  • Geothermal heat pump: CHF 40'000 to CHF 70'000 (drilling included)
  • Water-to-water heat pump: CHF 45'000 to CHF 65'000 depending on configuration

These amounts generally include removal of the old system, installation of the new pump, adaptation of the heating circuit and commissioning. Geothermal is more expensive to buy but offers the best efficiency over time.

Subsidies for heat pumps

Replacing fossil-fuel heating with a heat pump is strongly encouraged in Switzerland. Several forms of support can be combined:

  • The Buildings Programme: a federal and cantonal subsidy for replacing oil, gas or electric heating with a heat pump. Amounts vary by canton and output.
  • Cantonal grants: Geneva, Vaud and Valais have their own schemes, which are sometimes generous for phasing out fossil fuels.
  • The tax deduction: costs related to energy-efficiency renovation are generally deductible from taxable income.

All in all, subsidies can cover a significant share of the cost, especially when you replace a fossil-fuel boiler. The exact calculation depends on your canton and your situation.

Heat pumps and solar panels: the winning combination

It is one of the most relevant combinations for a modern property. A heat pump consumes electricity; solar panels produce it. Combining the two lets you power your heating with your own solar energy, drastically reducing your bills.

In practice, surplus solar production during the day can power the heat pump or charge a battery that then takes over. With smart energy management, self-consumption rises sharply and the whole system pays for itself faster. For a home aiming for energy autonomy, this is the benchmark configuration.

Performance and everyday comfort

Beyond the savings, a heat pump offers genuine comfort:

  • Gentle, even warmth, particularly pleasant with underfloor heating.
  • Cooling in summer: some reversible heat pumps can cool the home during heatwaves.
  • Quiet operation of recent models, an important criterion for high-end properties.
  • No combustion, no odours, and no more heating oil deliveries to organise.

Is it important to size your heat pump correctly?

It is essential. An undersized pump will struggle to heat in winter; an oversized pump will cycle on and off, wear out faster and consume more. Correct sizing depends on floor area, insulation, the type of heat emitters and the climate zone.

That is why a personalised study is indispensable. An experienced installer calculates your property's actual requirements before recommending an output — never the other way round.

In summary

Heat pumps in French-speaking Switzerland in 2026:

  • Efficiency: 3 to 5 kWh of heat for 1 kWh of electricity
  • Air-to-water: CHF 25'000 to 40'000  |  Geothermal: CHF 40'000 to 70'000
  • Substantial subsidies for replacing fossil-fuel heating
  • Solar pairing: maximum energy autonomy
  • Comfort, quiet and zero combustion
