Heat pump Winterthur: incentives, procedures and costs when replacing your heating

In Winterthur, the heat pump contribution comes from the Canton of Zurich: CHF 2,900 for an air-to-water heat pump up to 15 kW and CHF 6,800 for a ground probe system, plus CHF 160 and CHF 420 respectively for each additional kW above that. The city itself does not subsidise the heat pump – its programme pays for consultations, the building envelope, photovoltaics and connection to the heating network. And since the BVV amendment of 2023, many heat pumps run under the notification procedure instead of the building permit procedure; the noise protection certificate is still mandatory. (As of August 2026)

This page brings together what concretely matters when replacing a heating system in Winterthur: which contribution comes from whom, which procedure applies to your project and which proof must be available before construction starts.

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:

SystemSwissEnergy reference (single-family home, complete)Cost drivers
Air-to-water heat pumpCHF 45,000–60,000Unit, installation, hydraulics, boiler room adaptation
Brine-to-water (ground probe)CHF 55,000–80,000Ground 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.

The combination in detail

Who pays what in Winterthur?

The heat pump contribution is paid by the Canton of Zurich, not the city. For replacing an oil, gas or electric heating system in 2026, CHF 2,900 applies up to 15 kW of thermal output, plus CHF 160 per additional kW above that; for a ground probe or groundwater system CHF 6,800 up to 15 kW, plus CHF 420 per kW above that. A ground probe designed and operated without antifreeze brings an additional CHF 3,000 plus CHF 100 per kW. If you replace decentralised electric or fossil heating, the first installation of the heat distribution system is added: CHF 15,000 up to 250 m² of energy reference area, and CHF 60 per m² above that. All rates in detail: Heat pump incentives Canton of Zurich.

Stadtwerk's Energie Winterthur incentive programme supports consultations, the building envelope, photovoltaics and connection to a heating network – the latter with CHF 8,000 up to 15 kW of connected load, plus CHF 20 per additional kW, as well as CHF 1,600 plus CHF 40 per kW for the first installation of the heat distribution system. There is no city contribution to the heat pump itself. This is no minor detail: in Winterthur, connecting to the network is the deliberately subsidised route in some neighbourhoods – whether it's possible and sensible for you belongs before the system decision (District heating or heat pump).

The point at which incentive applications most often fail: district heating area and sequence. If, according to the canton's GIS browser (municipal energy planning map, «Förderung» layer), the property is in a district heating area marked in purple, the heat pump is not subsidised. There are three exceptions: confirmation from the network operator or municipality that the property is not to be connected; a network solution that is at least 10 percent more expensive than the heat pump according to EN-LCC-ZH; or a connection that is itself not eligible for incentives. And the application belongs before construction starts – installation of the heat pump or drilling of the ground probe counts as the start of construction. We check both for your address before planning.

Notification or building application: which procedure applies in Winterthur?

Three routes are open in the Canton of Zurich: the notification procedure, the permit procedure and the water-law concession procedure. The type, location and design of the system decide: air-to-water and brine-to-water heat pumps can go through the notification or permit procedure depending on the situation, groundwater heat pumps always go through the concession procedure. The notification is submitted digitally via the canton's upload tool. The basics on permits: Heat pump: permit or notification.

For air-to-water systems, the notification procedure also requires a noise protection certificate: LN-1a for easily assessable cases, LN-1b for complex ones – created via the Cercle Bruit web application, signed by the private inspection and submitted electronically via the EVEN platform. In addition, a cadastral plan with the location of the heat pump and the distance to the windows of noise-sensitive rooms is required. Living, dining and bedrooms and eat-in kitchens count as noise-sensitive – but not corridors, sanitary rooms, small storage rooms and closed kitchens under 6 m². What this means for placement: Location and noise and the noise regulations in detail.

For ground probes, the drilling location and the distance to the neighbouring property belong in the cadastral plan; if it is less than 2.5 metres, the neighbour's written consent is required. The utility cadastre plan must not be older than one year, and the cantonal application goes via the city's Building Permits Office to AWEL. Always required regardless of system: the GVZ WTA form, signed by a person authorised for private inspection, and the EN-103 heating and hot water certificate via EVEN.

Two things belong at the beginning, not the end: whether the building is in the inventory of buildings worthy of protection or in the core zone – then the city's heritage preservation office is involved – and whether the service connection is sufficient for the heat pump. For this, the technical connection application is submitted to Stadtwerk early on. Basis: Energy Office of the City of Winterthur, «Bewilligungs- und Meldeverfahren für Wärmepumpen», summary of 20 January 2026. The current provisions apply.

How your project works

  1. Inventory. Heating, distribution, hot water and consumption – ideally while the old system is still running.
  2. Procedure and zone clarification. Notification or permit procedure, district heating area, heritage protection, noise distances – clarified before choosing the system.
  3. Heating load calculation & quote. Sizing based on calculation, quote with individually listed items.
  4. Incentive application before construction. Submit and wait for confirmation of receipt – only then is anything ordered.
  5. Certificates & registrations. Noise protection certificate, EN-103, WTA form and the technical connection application to Stadtwerk.
  6. Removal & installation. Old heating out, heat pump in – a few working days for a single-family home.
  7. Commissioning & fine-tuning. Set the heating curve, instruct, readjust – the point at which efficiency is decided.

Frequently asked questions

Does the City of Winterthur pay a contribution towards the heat pump?
No. The Energie Winterthur incentive programme supports consultations, the building envelope, photovoltaics and connection to a heating network, but not the heat pump itself. The heat pump contribution comes from the Canton of Zurich: CHF 2,900 for air-to-water up to 15 kW and CHF 6,800 for ground probe or groundwater, plus a supplement for each additional kW above that.
Do I need a building permit for the heat pump in Winterthur?
Not necessarily. Since the BVV amendment of 2023, a heat pump can be handled under the notification procedure; whether this applies to your project depends on the type, location and design of the system. Groundwater heat pumps always go through the water-law concession procedure. The notification duty does not change the fact that building regulations must be complied with.
What is the noise protection certificate and who prepares it?
It proves that the noise limits and the precautionary principle are met, and is required for air-to-water heat pumps even under the notification procedure. There are two forms: LN-1a for easily assessable cases and LN-1b for complex ones. The certificate is created via the Cercle Bruit web application, signed by the private inspection and submitted via the EVEN platform. We handle this as part of the project planning.
What applies to a ground probe in Winterthur?
The drilling location and the distance to the neighbouring property belong in the cadastral plan; if the distance is less than 2.5 metres, the neighbour's written consent is required. The city also requires a utility cadastre plan that is not older than one year. The drilling itself is permitted by AWEL; the documents go there via the Building Permits Office.
What happens if my house is in a district heating area?
Then the cantonal incentive may not apply: in district heating areas marked in purple in the municipal energy planning, the heat pump is not subsidised. Exceptions are possible if the network operator or municipality confirms that there will be no connection, if the network solution is at least 10 percent more expensive according to EN-LCC-ZH, or if the connection itself is not eligible for incentives. We check this for your address before planning.
Does a heat pump work in an older Winterthur building with radiators?
In many cases, yes. What matters is the required flow temperature, not the year of construction; today's units reach it much better than earlier generations. Whether it's enough in your house is shown by the heating load calculation, and sometimes replacing individual radiators is cheaper than a larger unit.
How long does a heating replacement take in Winterthur?
The installation itself takes a few working days for a single-family home. What takes time is everything before: inventory, procedure clarification, quote, incentive application and certificates add up to several months. Plan in spring for the summer, and an interruption won't affect anyone.
