This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 6 % | 6.1 % |
| Heating oil | 16 % | 15.2 % |
| District heating | 31 % | 30.1 % |
| Heat pump | 25 % | 24.3 % |
| Electricity | 1 % | 10.5 % |
| Wood | 20 % | 6.7 % |
| Solar thermal | 0 % | 7.1 % |
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.
11.4 % of buildings mix housing with shops or offices.
For your renovation plans in Grabs, please note that the federal building register data is currently partial. With a median house volume of 776 m3 calculated from a sample of 30 buildings based on the SIA 416 standard, these figures provide a baseline for estimating the scale of your heating or insulation upgrades. As the register covers 2120 buildings, please be aware that information regarding renovation years is unavailable and no properties are recorded as protected heritage sites. Consequently, you should rely on professional on-site assessments for these specific aspects while using the volume data as a reference.

Solar thermal collectors capture solar radiation to heat a heat transfer fluid, which then transfers the warmth to your hot water tank. Solar thermal collectors usually cover much of summer hot water, providing an efficient and sustainable solution.
Note that performance depends heavily on your roof's tilt and orientation. To get a realistic estimate of installation costs for your home in Grabs, consult our online RenoIndex tool for a quick assessment and to ensure your budget is properly aligned.
To maximize the efficiency of your renovation, combining systems is often considered. However, combining collectors with a heat pump needs a sizing study to ensure optimal performance.

In Switzerland, installing solar collectors on a roof is generally subject to a notification procedure. Please check specific requirements with the municipality of Grabs, as protected areas may have stricter conditions. In the canton of St. Gallen, compliance with safety and urban planning standards is required for any structural modification to your property.
No, subsidies never cover the total costs. They act as a financial incentive to reduce your share. It is essential to plan for personal financing. Use our RenoIndex estimator to find out the actual cost of the work and estimate your overall financial investment after deducting potential aid for your project.
The installation itself usually takes between a few days and a week, depending on the complexity of the roof and hydraulic integration. Planning and obtaining permits can extend the project timeline. A professional will be able to provide you with a detailed schedule tailored to your specific situation in Grabs when preparing the quote.
Yes, but with reduced efficiency due to low solar intensity and low temperatures. Thermal collectors are mainly a supplement for domestic hot water. In winter, your main heating system will take over to ensure thermal comfort. RenoIndex helps you calculate the expected performance of your installation based on your specific location and configuration.
