This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Heating oil | 35 % | 24.2 % |
| District heating | 27 % | 30.3 % |
| Heat pump | 29 % | 4.6 % |

| Wood | 3 % | 1.9 % |
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.
10.9 % of buildings mix housing with shops or offices.
For your renovation planning in Bremgarten, the RegBL data shows that 290 buildings are under heritage protection, requiring you to contact the municipality early regarding building permits. Regarding the scale of your project, the median building volume of 280 m3 provides a reference for estimating heating or insulation works. However, this metric is limited as the data is only available for one out of 843 recorded houses. Use these official figures to better anticipate the technical and regulatory requirements specific to your property before starting your renovations to ensure a smooth project execution.

A solar thermal system captures energy from the sun using collectors mounted on your roof. A heat transfer fluid circulates through these panels, absorbs heat, and then transfers it to a storage tank.
This allows you to preheat or directly heat your domestic hot water. It is important to note that combining collectors with a heat pump requires a careful sizing study.
This technical step ensures optimal efficiency throughout the year, even when sunlight levels are lower during the winter months in the canton of Aargau.
Investing in solar thermal energy significantly reduces your reliance on fossil fuels. By installing high-performance collectors, you increase the value of your property in Bremgarten while lowering your monthly operating costs.
Since several cantons subsidise collectors per square metre or per installation, it is wise to research available support before starting work.
Although no specific municipal grants exist for Bremgarten, switching to solar power is a significant contribution to the energy transition. Use the RenoIndex calculator to quickly estimate the return on investment for your solar installation.
The installation requires a roof in good condition, ideally oriented towards the south. It is essential to assess the load-bearing capacity of your roof structure. Sizing the hot water tank is also a critical step to ensure sufficient autonomy.
Remember that combining collectors with a heat pump requires a thorough sizing study to avoid summer overheating or winter supply shortages.
Hiring a qualified professional in Bremgarten ensures that your installation complies with the technical and safety standards currently in force in the canton of Aargau.
Before getting started, compare several quotes from local companies. Always check the compatibility of your existing heating system with the new collectors.
Solar thermal collectors usually cover much of the hot water demand during the summer, allowing your main boiler to remain inactive during that period. To structure your budget and plan your expenses with confidence, use the free RenoIndex calculator.

Modern solar thermal systems are designed to last between 20 and 25 years with regular maintenance. It is advisable to have the heat transfer fluid and the system's integrity checked every few years by a professional to maintain optimal efficiency over the long term.
Yes, collectors still work in winter thanks to diffuse radiation, although the yield is lower than in summer. They serve to preheat water, which eases the load on your main heating system and reduces your overall energy consumption during the colder months.
Generally, roof-integrated solar installations do not require a building permit, but a prior notification to the municipality is often required. Always check with the authorities in Bremgarten if your building is listed or located in a specific protected zone.
