Heat pump Schaffhausen: incentives, conditions and costs when replacing your heating
When replacing a fossil or electric heating system in a single- or two-family home, the Canton of Schaffhausen pays CHF 3,000 for an air-to-water heat pump and CHF 10,000 for a brine-to-water or water-to-water system; from three dwellings, it's CHF 7,000 and CHF 18,000 respectively. The catch hardly anyone mentions: in single- and two-family homes, the air-to-water heat pump is only eligible if a solar power system with at least 30 watts per square metre of energy reference area exists or is built. If you plan both together, you also get an additional solar power contribution. (As of August 2026)
This page brings together what concretely matters when replacing a heating system in the Canton of Schaffhausen: the 2026 incentive rates, the conditions on which applications actually fail, and the process from inventory to commissioning.

What does a heat pump cost?
Costs depend on the system, the condition of the heat distribution and the structural conditions. The reference is SwissEnergy's empirical values for a single-family home, including storage tank and hydraulic integration:
| System | SwissEnergy reference (single-family home, complete) | Cost drivers |
|---|---|---|
| Air-to-water heat pump | CHF 45,000–60,000 | Unit, installation, hydraulics, boiler room adaptation |
| Brine-to-water (ground probe) | CHF 55,000–80,000 | Ground probe drilling (depth and subsoil) |
Guideline values according to SwissEnergy, before incentives; they include heat pump, installation, storage tank and hydraulics. Removal of the old heating and permits are not explicitly included. The individual quote is binding.
In Schaffhausen, the solar system on a single-family home decides whether the air-to-water heat pump is subsidised – we calculate both sides in one quote.
Heat pump incentives in the Canton of Schaffhausen
The replacement of an oil, gas or electric heating system is subsidised. For systems up to 70 kW thermal rated output, in single- and two-family homes CHF 3,000 applies for an air-to-water heat pump and CHF 10,000 for brine-to-water or water-to-water; from three dwellings and for non-residential buildings, the rates rise to CHF 7,000 and CHF 18,000 respectively. From 20 kW, output-based contributions are added, and the assessment is capped at 50 watts per m² of energy reference area.
On top comes the additional contribution for solar power systems with heat pumps: CHF 3,200 for air-to-water and CHF 4,800 for brine-to-water or water-to-water, at least CHF 3,000 and at most CHF 20,000. And anyone who replaces decentralised electric resistance heating or decentralised fossil heating receives CHF 15,000 for the first installation of the hydraulic heat distribution system up to 250 m² ERA, and CHF 60 per m² above that.
In practice, three conditions decide between approval and rejection. The application belongs before construction starts. The contribution may not exceed 50 percent of the total investment. And in single- and two-family homes, the hot water must be connected to the new heat generation system. Up to 15 kW, a certified heat pump system module is also mandatory; above that, a valid quality label with performance guarantee.
A clarification, because it is often told the wrong way round: the incentives of the City of Schaffhausen and the municipalities of Neuhausen am Rheinfall and Thayngen concern the building envelope, not the heat pump. They are automatically applied for with the same application – if you're planning insulation anyway, don't push it into a separate procedure. Rates and conditions: 2026 energy incentive programme of the Canton of Schaffhausen, as of 1 January 2026.
The condition that decides incentives for single-family homes
Schaffhausen links heat and electricity more closely than neighbouring cantons: air-to-water heat pumps in single- and two-family homes are only eligible if a solar power system with at least 30 watts per square metre of energy reference area is newly installed, already exists or is extended to this value. With 200 m² ERA, that's around 6 kWp – a normal size for a typical single-family roof, but a requirement, not an option.
In practice, this means: anyone who only replaces the heating in a single-family home and leaves the roof untouched receives no cantonal contribution for the air-to-water heat pump. Anyone who plans both together gets the contribution and the additional solar contribution and cheaper electricity for the heat pump. We plan exactly this sequence in one quote instead of two (Running a heat pump on solar power).
The solar condition does not apply to the ground probe – there, the higher base contribution of CHF 10,000 applies without this requirement. Whether drilling pays off and is permitted at your location is decided by the subsoil, not the catalogue: Ground probe: when drilling pays off.
On the legal situation for heating replacement – proof requirements, standard solutions, any deadlines for electric heating – the current cantonal requirements apply in the Canton of Schaffhausen; we clarify them with the energy office and your municipality before planning, rather than claiming a figure here. What matters technically is shown by the heating load calculation anyway: sizing correctly, heat pumps in older buildings.

How your project works
- Inventory. Heating, distribution, hot water and consumption – ideally while the old system is still running.
- System and incentive clarification. Air-to-water or ground probe – in Schaffhausen, the incentive for single-family homes depends on the solar system, so that comes before choosing the system.
- Heating load calculation & quote. Sizing based on calculation, quote with individually listed items.
- Incentive application before construction. Submit and wait for approval – only then is anything ordered.
- Notification & permits. We handle the municipality, grid operator and, for ground probes, the drilling permit.
- Removal & installation. Old heating out, heat pump in – a few working days for a single-family home.
- Commissioning & fine-tuning. Set the heating curve, instruct, readjust – the point at which efficiency is decided.
