The price of a heat pump is not the easiest subject to explain. Many factors come into play, and the ranges quoted online are rarely representative of what a real project costs in French-speaking Switzerland. This article brings together our 2026 field figures from residential installations, clearly distinguishing gross cost, net cost after grants, and the hidden costs that nobody likes to discuss.
What does a heat pump really cost in 2026
For a quick reference, here are the ranges we see on boiler-replacement projects in French-speaking Switzerland in 2026, fully installed.
Air-to-water heat pump for a 100–180 m² house: CHF 32,000 to CHF 48,000 gross.
Air-to-water heat pump for a large 200–300 m² house: CHF 42,000 to CHF 58,000 gross.
Vertical geothermal heat pump, 100–180 m²: CHF 55,000 to CHF 78,000 gross, including boreholes.
Vertical geothermal heat pump, 200–300 m²: CHF 70,000 to CHF 95,000 gross.
Water-to-water (groundwater), where permittable: CHF 75,000 to CHF 110,000 gross.
These figures include: thermal study, equipment supply, hydraulic and electrical installation, removal of the existing heating system, circuit adaptation (except complex cases), commissioning, and fine-tuning. Excludes options: separate thermodynamic cylinder, additional expansion vessel, distribution board modification on older installations, radiator adaptation where required.
The cost structure of an air-to-water heat pump
To understand what you are buying, here is a typical cost breakdown for a 10 kW air-to-water heat pump in a standard house.
| Item | Indicative cost | Share of total |
|---|---|---|
| Heat pump (equipment) | CHF 14,000 – 18,000 | ~40% |
| Domestic hot water cylinder or tank-in-tank | CHF 2,500 – 4,500 | ~9% |
| Hydraulics (pump, valves, expansion vessel) | CHF 2,000 – 3,500 | ~7% |
| Installation and connections | CHF 5,500 – 8,000 | ~17% |
| Electrical work, communication, fine-tuning | CHF 2,500 – 4,000 | ~7% |
| Removal of existing heating + oil tank | CHF 2,500 – 5,500 | ~10% |
| Thermal study + administrative work | CHF 1,500 – 2,500 | ~5% |
| Commissioning + 1-year monitoring | CHF 1,000 – 2,000 | ~3% |
The only item with a real quality variable is the main equipment. A Daikin Altherma 3 H HT at CHF 17,000 is not the same product as a no-name heat pump at CHF 9,000. Over 25 years of use, the difference shows in performance, noise levels, after-sales service availability, and reliability.
Brands and their price positioning
The French-speaking Swiss market is dominated by a handful of brands, each with its own positioning.
Daikin (Japan). The market reference. Altherma 3 H HT for premium residential, Altherma 3 R for the standard range. Excellent SCOP, controlled noise levels, solid after-sales service in French-speaking Switzerland. 5–10% more expensive than mid-market.
Mitsubishi (Japan). Ecodan — the direct equivalent of Daikin. Very similar performance, different aesthetics, sometimes more readily available.
Hitachi (Japan). Yutaki — full range, good value for money, growing deployment in French-speaking Switzerland.
Viessmann (Germany). Vitocal — European manufacturing, connected Vitoconnect ecosystem, seamless integration with hybrid solar boilers. Price often slightly higher.
Bosch (Germany). Compress 7000 — clear, reliable range, widely deployed.
STIEBEL ELTRON (Germany). Historic specialist, premium range, particularly relevant for geothermal installations.
CTA (Switzerland). An interesting local player, Swiss manufacturing, highly responsive after-sales service. Often a good option in more remote areas.
To avoid: brands with no Swiss after-sales presence. A heat pump that breaks down after 7–8 years from an untraceable brand is a wasted investment.
The geothermal premium in detail
For those weighing up air-to-water against geothermal, here is the cost breakdown for the geothermal premium on a standard house.
| Additional geothermal item | Indicative cost |
|---|---|
| Boreholes (2–4 probes depending on output) | CHF 18,000 – 32,000 |
| Geothermal probes | CHF 4,500 – 8,000 |
| Collector, deep connections | CHF 2,500 – 4,500 |
| Preliminary geotechnical study | CHF 1,500 – 3,000 |
| Cantonal authorisation | CHF 500 – 1,500 (administrative fees) |
| Total geothermal premium | CHF 27,000 – 49,000 |
This premium is spread over 25–30 years (the superior service life of a geothermal heat pump) and benefits from a SCOP 20–25% higher than air-to-water. At a stable electricity tariff, payback on the premium is around 12–15 years. In new construction, where part of the borehole benefits from existing excavation, the net premium can fall to CHF 18,000–25,000, which changes the calculation significantly.
Grants in 2026 and the effective net cost
Cantonal grants for heat pumps replacing fossil heating are among the most stable and generous in the Swiss energy subsidy landscape. The cantonal Building Programme is the cornerstone.
Vaud cantonal grant (Building Programme) in 2026: between CHF 4,000 and CHF 8,000 depending on output and type, sometimes more for specific cases (sensitive zones, combined thermal renovation).
Geneva grant (GEnergie): equivalent amounts, under the programme in force.
Fribourg grant: aligned with the Building Programme, comparable amounts.
Neuchâtel grant: generally integrated into a global energy plan.
Valais grant: active cantonal programme, particularly for renovation.
Municipal grants: in certain municipalities in Vaud, Fribourg, and Geneva, local grants are added. In others, nothing.
Tax deduction: the net cost after grants is deductible. At a marginal rate of 27%, that is a 27% tax saving on the net amount.
A worked example: 160 m² house in Vaud, 10 kW air-to-water heat pump, gross cost CHF 38,000.
- Vaud cantonal grant: –CHF 6,500
- Municipal grant (depending on location): CHF 0 to –CHF 2,000
- Sub-total after grants: CHF 29,500 to CHF 31,500
- Tax saving (marginal rate 27%): –CHF 7,960 to –CHF 8,500
- Effective net cost: CHF 21,000 – 23,500
That represents total assistance (grants + tax) of around 40–43% of the gross cost — which is what makes the investment worthwhile.
Comparative running costs
Beyond the purchase price, it is the total cost over 20 years that counts. Take a house currently consuming 3,000 litres of oil per year.
Oil (reference): 3,000 L × CHF 1.30/L = CHF 3,900/year.
Air-to-water heat pump, SCOP 4: 7,500 kWh/year × CHF 0.28/kWh = CHF 2,100/year.
Geothermal heat pump, SCOP 4.8: 6,250 kWh/year × CHF 0.28/kWh = CHF 1,750/year.
Annual saving from an air-to-water heat pump compared with oil: CHF 1,800/year — CHF 36,000 cumulative over 20 years (and more if oil prices rise, which is likely).
Annual saving from a geothermal heat pump: CHF 2,150/year — CHF 43,000 cumulative over 20 years.
Over the life of a heat pump, these figures far exceed the initial replacement premium compared with maintaining an oil boiler — which is no longer permitted in most French-speaking cantons in any case.
Hidden costs to anticipate
A few items that are not always included in quotations and that can come as a surprise.
Removing the oil tank. For buried tanks, this can add CHF 4,000–7,000 on top of the quoted price if not included. Ask explicitly.
Possible electrical upgrades. In houses from the 1970s–1980s, the distribution board may need upgrading to handle the heat pump's electrical demand. Allow CHF 1,500–3,500.
Dedicated domestic hot water cylinder. If you currently have an ageing oil-fired cylinder and plan a separate thermodynamic cylinder in addition to the tank-in-tank included in the quotation, that is an additional CHF 2,500–4,500.
Mechanical ventilation. When a heating system is replaced and insulation is improved in parallel, mechanical ventilation becomes almost essential to prevent humidity problems. Allow CHF 6,000–12,000 for a basic installation.
Finishing repairs. Routing pipes may require some plastering or repainting, rarely costed in initial quotations.
A quotation that explicitly addresses these points is generally a serious one. One that ignores them exposes you to subsequent cost overruns of CHF 5,000 to CHF 10,000, discovered once the works are under way.
Our advice for 2026
When comparing quotations, do not look at the overall price alone. Compare line by line:
- The exact brand and output of the heat pump.
- The cylinder brand and capacity.
- The system warranty (10, 12, or 15 years).
- The SCOP quoted for your specific property.
- The scope of the administrative procedures.
- The first-year monitoring offered (seasonal fine-tuning).
A quotation CHF 5,000 cheaper than the competition almost always cuts corners on one of these items. The right approach: ask the installer to justify their price, point by point. That is usually when you discover what is not included.
A heat pump lasts 25 years. The right quotation is not the cheapest: it is the one that explains everything clearly, and that will still be there in 10 years for maintenance.
