This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 9 % | 8.2 % |
| Heating oil | 38 % | 28.5 % |
| Heat pump | 42 % | 22.9 % |

Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
A standard non-condensing boiler is usually older and less efficient.
9 % of buildings mix housing with shops or offices.
For your renovation plans in Gossau (ZH), federal building records provide useful baseline figures. The median house volume is 727 m3 according to the SIA 416 standard, which is vital for scaling your heating and insulation upgrades appropriately. Please note this measurement covers only 33 out of 1488 houses, as other standards apply to the rest.

Solar thermal collectors capture solar radiation to heat a heat-transfer fluid circulating in the primary circuit. The heat is then transferred to your storage tank via a heat exchanger.
In Switzerland, particularly in the canton of Zurich, this technology is highly efficient. Solar thermal collectors usually cover much of summer hot water, thus reducing the load on your main boiler.
It is a sustainable investment that increases your property value while actively participating in the local energy transition through renewable energy usage.
Installation is not limited to placing collectors on the roof. It is crucial to integrate them harmoniously into your existing heating system. Combining collectors with a heat pump needs a sizing study to ensure optimal efficiency throughout the year.
Professionals in the canton of Zurich often recommend a comprehensive thermal analysis before validating the installation plan. Poor planning could limit the performance of your system.
Consult our tools at RenoIndex to better understand the technical requirements of your building and ensure optimal system configuration.
To find out about the aid available for your project in Gossau (ZH), it is advisable to check the current programs in the canton of Zurich regularly. These measures aim to encourage owners to adopt cleaner systems.
