The city of Zurich aims to reduce its carbon emissions to net zero by 2040. One of the most urgent and effective projects is to replace fossil fuel-powered heating systems with climate-friendly district heating. The waste incineration and wood heating network makes an important contribution to this. As local, renewable energy sources, ewz primarily uses waste heat from the waste incineration plant in Hagenholz and heat from the Aubrugg wood-fired combined heat and power plant.
With a connection to the waste incineration and wood heating network, we supply you with renewable energy for heating and the generation of hot water. On the long-term average, the energy mix is around 70 percent carbon-neutral.
The following variants are available:
Connection and energy supply
- Connection of your property to the district heating network
- Supply of district heating
Connection preparation (on request)
- Preparing for connection of your property to the district heating network
- Supply of district heating at a later date, e.g. when replacing a heating system
We bear the financial and technical responsibility. You pay for the volume of energy purchased and the output power.
We monitor the supply to your property around the clock. You benefit from high availability.
We supply you with heat from local renewable energy sources. They meet all legal requirements.
Find out about the current district heating tariff system 2022 and the General Terms and Conditions (in German). The 2020 district heating tariff system can be found here.
The price is made up of three components:
- Connection fee: one-off set-up costs
- Price per unit: your consumption-based energy costs
- Demand rate: costs for infrastructure, servicing and maintenance as well as for the 24-hour on-call service
The city and canton of Zurich subsidise connection to heating networks. Find out more on the website of the City of Zurich (in German). You must submit your application for subsidies before renovating your heating system.
The link between your district heating system and your property’s heating system is the transfer station. This includes all the required technology, e.g. heat exchangers, energy meters and regulators. A calibrated meter measures and calculates the heat or cooling consumed.
The technical conditions help you carry out your connection to the district heating system smoothly. These differ depending on the supply area:
- Zurich North, Opfikon and Wallisellen networks (in German)
- Zurich West and Zurich South networks (Sihlquai and Aussersihl) (in German)
- Zurich Mitte network (Wipkingen, Oberstrass, Unterstrass) (in German)
- University district network (in German)
In our document centre, you will find
- the specifications for the compact heat transfer station (in German) (up to 80 kW connected load in the Zurich North and Opfikon networks)
- a list of suppliers for compact heat transfer stations (in German)
- a checklist for commissioning the heat transfer station (in German)
- a checklist for commissioning the compact heat transfer station (in German)
- instructions for heat meter reading
