A standard non-condensing boiler is usually older and less efficient.
Renovations, heritage and volumes
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.

Planning your heating project
Before starting, first check whether your area can connect to a priority district heating network, as this may influence your choice of technology. The local design outdoor temperature sets the heat pump's capacity required to heat your home efficiently.
A preliminary heat demand study helps evaluate your building's overall energy performance. We advise reviewing cantonal guidelines regarding heating system compliance. Use the RenoIndex estimator to get a clear view of your expected costs.
Complying with local noise regulations
It is crucial to choose a strategic location, away from bedrooms and property boundaries, to minimize noise disturbance. Acoustic insulation measures can also be added if necessary.
Remember that RenoIndex helps you anticipate the costs associated with a professional installation that complies with current standards.
Energy optimization and efficiency
The efficiency of a heat pump depends heavily on your home's thermal insulation. Before installation, ensure that heat losses are limited through proper roof or window insulation.
A heat pump is particularly efficient with low-temperature distribution systems, such as underfloor heating. In the case of traditional radiators, an upgrade might be necessary to maximize yield.

The role of the qualified professional
Hiring a specialized company is essential to guarantee a compliant installation. An expert can assess the appropriate power based on the local design temperature and ensure that the hydraulic integration is correct.
Installers are familiar with the technical requirements in the canton of St. Gallen and will advise you on the most suitable heat pump model. They will also handle commissioning and maintenance.

Frequently asked questions
What is the lifespan of a heat pump?
A well-maintained heat pump typically has an average lifespan of 15 to 20 years. Regular maintenance by a professional is essential to maintain performance and prevent premature wear of internal components.
Is a heat pump noisy?
Modern models have become very quiet. However, outdoor units produce a constant airflow. By maintaining an adequate distance from neighbours and choosing an open location, you will easily comply with the applicable noise limits.
Do I need to modify my radiators?
Heat pumps work best with low-temperature systems. If your radiators are old, they might require a high water temperature. Sometimes, replacing them with larger or more efficient models is enough to optimize overall performance.
How can I estimate the total cost?
Costs vary based on soil type and required power. To obtain a realistic price range adapted to your specific project, use the RenoIndex simulator for free and get a clear estimate for your renovation.
