This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 44 % | 35.2 % |
| Heating oil | 23 % | 10.3 % |
| District heating | 1 % | 0 % |
| Heat pump | 24 % | 20.2 % |
| Electricity | 6 % | 32.7 % |
| Wood | 2 % | 0.7 % |
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.
10.7 % of buildings mix housing with shops or offices.
For your renovation plans in Richterswil, the official building register provides useful insights, though coverage remains partial. With a median building volume of 1103 m3 according to the SIA 416 standard for the eight measured structures, this figure helps you gauge the scale required for heating or insulation upgrades. Given that these metrics represent only a small fraction of the total housing stock, they should serve as an initial guideline rather than a definitive assessment. We recommend conducting a professional on-site evaluation to determine your specific project requirements accurately before proceeding with your renovation budget.

Installing solar thermal collectors is an excellent way to reduce your energy bills. Generally, solar thermal collectors cover a large portion of hot water needs during the summer period.
This allows your main heating system to stay off or run at a lower intensity, thus extending its lifespan. A preliminary study helps evaluate the sunlight exposure on your roof in Richterswil to maximise efficiency.
Consult RenoIndex to get a clear cost estimate for installation and optimise your energy investment from the very beginning of your project.
Combining solar collectors with a heat pump is an increasingly common strategy to achieve optimal energy efficiency. However, this setup requires a rigorous sizing study carried out by a professional.
It is crucial to harmonise storage capacity and collector surface area with your household's actual demand. A well-sized system ensures stable performance throughout the year.
To estimate these components, do not hesitate to use the free RenoIndex simulator to obtain realistic price ranges adapted to the Swiss market.
It is important to find out about the current programmes before starting work. Although every project is unique, RenoIndex helps you anticipate your net investment by providing accurate price estimates.
By comparing this data with subsidies available at the cantonal level, you will be able to better define your final budget for your solar project in Richterswil.
A solar thermal system requires little maintenance, but periodic checks are recommended to ensure maximum performance. Checking the heat transfer fluid pressure and component status helps avoid efficiency losses over time.
