Swissthermic SA is a Swiss company that specializes in heat pump installation and heating system replacement across French-speaking Switzerland. Based in the Canton of Vaud, the firm focuses on helping homeowners and businesses transition away from traditional oil and gas heating toward more energy-efficient alternatives. The company has been operating since 2012 and has built a client base of over 1,000 property owners throughout Suisse Romande.

The core service offering revolves around heat pump technology. Swissthermic installs air-to-water heat pumps, geothermal systems, and thermodynamic water heaters. These systems extract energy from the surrounding environment to heat buildings and produce hot water. For anyone unfamiliar with how this works, think of it like a refrigerator running in reverse—pulling warmth from outside air or the ground and transferring it indoors. As a reviewer, I find this technology particularly relevant for Swiss homeowners facing rising energy costs and stricter environmental regulations.

What sets this company apart is their turnkey approach. They handle everything from the initial diagnostic assessment through to final installation and beyond. This includes conducting free thermal studies, preparing transparent quotes, managing permits, coordinating with tenants in multi-unit buildings, and helping clients navigate the paperwork for federal and cantonal subsidies. Programs like ProKilowatt can significantly reduce upfront costs, and Swissthermic guides customers through the application process.

The company serves both residential and commercial clients. For homeowners, they offer solutions compatible with existing radiators or underfloor heating systems. Commercial clients—landlords, property managers, building owners—can take advantage of phased installation plans that minimize disruption to tenants while spreading costs over time. In my opinion, this flexibility makes sense for larger properties where a complete system overhaul might otherwise cause significant inconvenience.

Swissthermic employs certified Swiss engineers who understand local building codes and climate conditions. Swiss winters can be harsh, and heat pumps need proper sizing and installation to perform effectively when temperatures drop. The company uses equipment specifically designed for cold climates, ensuring reliable heating even on the coldest days. They partner with manufacturers like ACOND for their air-to-water heat pump systems.

Maintenance services round out their offering. Regular servicing—filter checks, refrigerant inspections, descaling of water heaters—keeps systems running efficiently and extends equipment lifespan. Heat pumps from quality manufacturers typically last 15 to 20 years with proper care, so ongoing maintenance isn't just about preventing breakdowns; it's about protecting a long-term investment. The company also provides emergency repair services, with availability around the clock for urgent situations.

Energy savings represent a major selling point for heat pump conversions. Swissthermic reports that most customers achieve 30 to 50 percent reductions in heating costs compared to their previous systems. The exact savings depend on factors like property size, insulation quality, and what type of heating is being replaced. During the free diagnostic, the company provides personalized estimates based on each property's specific characteristics.

The company operates throughout Suisse Romande with particular activity in Vaud, Fribourg, and the Lavaux region. Their local presence means familiarity with regional regulations, cantonal subsidy programs, and the specific heating challenges that Swiss properties face. Installation timelines typically run one to three days for residential projects, though commercial installations may take longer depending on building complexity.

For property owners considering a heating system upgrade, Swissthermic positions itself as a single point of contact for the entire process. From assessing whether a heat pump makes sense for a particular building, through selecting appropriate equipment, handling administrative requirements, completing installation, and providing ongoing support—they aim to manage the transition without leaving clients to coordinate multiple contractors or wade through bureaucratic procedures on their own.
