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 homeowners planning renovations in Romanshorn, official RegBL figures provide vital context. Data coverage regarding building volume is partial, with seven houses measured under the SIA 416 standard showing a median volume of 830 m3, which helps gauge the scale of necessary heating or insulation work. Regarding heritage protection, out of 2023 registered buildings, 278 are known, with zero recorded as protected. We recommend contacting the municipality early in your planning process to confirm your property's specific status, as this ensures all local permit requirements are fully addressed before you begin any construction projects.

Solar thermal collectors are designed to convert solar radiation into heat. These systems usually cover a large portion of your hot water needs, especially during the summer season.
By integrating this solution into your home heating system, you reduce your reliance on fossil fuels. To ensure optimal efficiency, it is recommended to engage a qualified professional who can assess your roof's orientation and tilt.
Correct sizing is crucial to avoid over-storage or unnecessary heat losses during periods of low winter sunlight.
Combining thermal collectors with a modern heat pump is a high-performance strategy for managing your home's energy. However, this configuration requires a rigorous sizing study.
The goal is to ensure that both systems work in perfect synergy without overloading the thermal network.
A well-thought-out installation allows for optimal overall efficiency, particularly by using solar energy to preheat water before it passes through the heat pump.
We advise you to consult RenoIndex to estimate the costs of this complex installation and better plan your budget before contacting local firms.
Although no specific municipal rules are listed for Romanshorn, several cantons subsidise solar collectors, either per square metre installed or as a flat rate per installation.
It is strongly advised to check current programmes at the canton of Thurgau level before confirming your quote. These grants can significantly reduce the initial investment.
RenoIndex helps you see more clearly by providing an estimate of the total costs, allowing you to better anticipate the return on investment for your project.
Planning is the most important step in any energy renovation project. Start by defining your priorities: is it only for hot water production, or do you also want to support heating?
Once your needs are identified, request several quotes from local businesses to compare offers. Also, remember to check for any potential restrictions linked to your residential zone.
By using RenoIndex, you benefit from a reliable calculation basis in CHF to compare the quotes received. Good preparation will avoid financial surprises and ensure your solar thermal installation in Romanshorn meets your expectations long-term.
