Planning your energy transition
The first step is to analyze your current heating system. First, check whether your area can connect to a priority district heating network, which is often a preferred solution. Once that option is ruled out, examine your building's insulation.
A heat pump is more efficient when heat demand is low. The local design outdoor temperature sets the heat pump's capacity needed to keep your home comfortable, even on the coldest winter days.
Take the time to conduct an energy audit to ensure your installation is properly sized for your specific property.
Technical constraints and noise regulations
Choose a smart location, ideally away from bedrooms or sitting areas, and consider acoustic screening if necessary. In the canton of St.
Gallen, noise protection regulations must be strictly adhered to when submitting your building permit application for any permanent installation to avoid any potential legal or neighborly issues.
Cost estimation and budget
The cost of a heat pump varies depending on the technology, required capacity, and the necessary connection work.
Beyond the unit price, you must include professional installation fees, potential geothermal drilling, and adjustments to existing heat distribution systems. To get a clear idea of the overall budget, use the free RenoIndex simulator.
