The heat pump extracts thermal energy from the ambient air. The refrigerant absorbs this heat in the heat exchanger (evaporator) and is then compressed in the compressor. The heat generated in this process is used for heating and hot water production via another heat exchanger. In summer, the cycle can also be used for cooling by reversing the process.
The heat pump extracts thermal energy from the ground using a geothermal probe or groundwater. The refrigerant absorbs this heat in the heat exchanger (evaporator) and is then compressed in the compressor. The heat generated in this process is used for heating and hot water production via another heat exchanger. In summer, the cycle can also be used for cooling by reversing the process.
Heat pumps are suitable for both and can therefore be used in new buildings and old buildings undergoing renovation. With the latest generation of heat pumps, flow temperatures of up to 70° can be achieved.
However, it may be worth replacing or adding new radiators with a larger heating surface area in order to increase the efficiency of the heat pump. Seek advice from a specialist. In general, energy-saving measures should be considered for the building envelope in order to directly reduce the heat demand and thus reduce the flow temperatures and increase the efficiency of the heat pump.
Yes, because all our heat pump systems are designed for the design temperature. However, there are some differences between the various heat pump systems that need to be taken into account:
Air/water heat pumps:
Air/water heat pumps have a lower operating limit (approx. -25°C). For heating systems, this means that the heat output is guaranteed up to the design temperature (in the Swiss Plateau, for example, at -7°C). If the outside temperature falls below this design temperature, the auxiliary heating can switch on automatically. Statistically speaking, however, this is extremely rare.
Brine/water heat pumps:
With brine/water heat pumps, it is important to dimension the geothermal probes correctly. The geothermal energy at depth is constant and changes only minimally, even if the top layer of soil is frozen.
A heat pump with a COP of 5 requires 1/5 of the total energy produced in the form of electrical energy, while 4/5 of the energy is obtained from the environment (ambient air, geothermal probe, etc.).
The COP is highly dependent on the source temperature and the flow temperature. The higher the source temperature and the lower the flow temperature, the higher the COP and the energy efficiency.
In combination with a PV system, the amount of electricity consumed can be increased and energy costs reduced.
The sound insulation of heat pumps can be improved through structural measures. The most important measure is to physically decouple the heat pump from the house. Pipes must also be physically decoupled using suitable mounting systems. Sound insulation hoods or sound insulation walls can also significantly reduce noise levels.
Heat pumps are generally very low-maintenance. However, a heat pump should not be neglected. Contamination on the outdoor unit or in the heating circuit, incorrect settings, incorrect heating curves, etc. can damage the heat pump or reduce its efficiency. Periodic maintenance is therefore always beneficial and extends the service life.
The cost of a heat pump varies depending on the type and size of the system. An air/water heat pump for a single-family home of approximately 150 m² typically costs between CHF 30,000 and CHF 40,000, while a ground-source heat pump (geothermal energy) often costs between CHF 40,000 and CHF 50,000. Installation and additional work such as drilling or connection costs have a significant impact on the price.
Yes, both the federal government and the cantons offer subsidy programs to support the installation of heat pumps. The amount of the subsidy depends on the canton and the type of heat pump. There are often tax advantages in the form of deductions that can currently still be claimed. However, with the rejection of the owner-occupied housing allowance, this is expected to fall in 2028. Our sales advisors will be happy to provide you with more information.
Heat pumps have low operating costs compared to fossil fuels such as oil and gas. Operating costs are heavily dependent on energy costs, but correct hydraulic integration and correct operation also have an influence. In Switzerland, heat pumps are generally inexpensive to operate.
Heat pumps offer many advantages:
As a rule, replacement is possible. However, both the building envelope and the existing heating system must be taken into account. In very old buildings or those with poor insulation, it is advisable to first renovate the building envelope and then modernize the heating system.
The approval process varies from canton to canton. For many air/water heat pumps within the building zone, a notification procedure with the municipality is now sufficient, whereby the most important documents, including noise protection certification, must be submitted. In special cases (core zones, listed buildings, groundwater protection areas, or geothermal heat pumps), a building permit is required and, depending on the case, a cantonal drilling permit may also be necessary. Our sales staff will be happy to assist you with this.
Heat pumps are considered virtually carbon neutral, especially when the electricity comes from renewable sources. Compared to oil or gas heating systems, CO₂ emissions can be reduced by up to 95%.
Financially and ecologically, the switch is definitely worthwhile in the long term. The investment pays for itself over the years thanks to lower operating costs and subsidies. In addition, the value of the property increases when it is renovated with efficient technology. As fossil fuel heating systems will be gradually banned in the future, the switch is also a future-proof decision.
Yes, air/water heat pumps require a noise protection certificate, which must be issued by a specialist. This ensures that the legal noise limit values specified in the Noise Abatement Ordinance are complied with.
The ADAPT 2 heat pump delivers energy-efficient heating and cooling for Swiss homes. It operates exceptionally quietly, reliably, and automatically, ensuring you enjoy consistent comfort year-round—pleasantly warm in winter and gently cooled in summer. Thanks to high supply temperatures of up to 75 °C, the heat pump is suitable for both new construction with underfloor heating and for replacing oil or gas heating systems with radiators.
With a SCOP of up to 6.22, the ADAPT 2 is one of the most efficient heat pumps on the market and can reduce your heating costs by up to 60%. With a SCOP of up to 6.22, the ADAPT 2 air/water heat pump is one of the most efficient heat pumps on the market. This means: For every 1 kWh of electricity, the system generates up to 6.22 kWh of heat over the course of a year. This high energy efficiency ensures significantly lower operating costs and makes the ADAPT 2 a particularly cost-effective solution for energy-efficient heating in Switzerland. The heat pump can also be optimally combined with solar panels, energy storage systems, or existing heating systems, transforming your home into a smart energy system.
At the same time, it uses the natural refrigerant R290, which is particularly environmentally friendly and significantly reduces CO₂ emissions. The refrigerant R290 (propane) is currently considered one of the most environmentally friendly refrigerants for modern heat pumps. R290 has a very low global warming potential (GWP of just 3) and thus causes virtually no climate-damaging emissions. As a result, it already meets Switzerland’s strict environmental standards and is a future-proof solution for sustainable heating systems. Another advantage of R290 is its very high thermodynamic efficiency. Heat pumps using this natural refrigerant can achieve higher supply temperatures of up to 75 °C while operating with exceptional efficiency. This makes them ideal for both new construction projects with underfloor heating and retrofits with existing radiators.
Furthermore, R290 delivers very stable and reliable capacity even at low outdoor temperatures, which is a significant advantage, particularly in Switzerland with its cold winters. The heat pump can thus efficiently extract heat from the environment even during severe frost and use it for heating or warm water. Thanks to the combination of a natural refrigerant, high efficiency, and low environmental impact, R290 is now one of the most advanced technologies in the field of sustainable heat pumps—a solution that both reduces energy costs and actively contributes to climate protection.
The ADAPT 2’s whisper-quiet operation ensures that the heat pump is barely noticeable in everyday life. Thanks to optimized airflow, high-quality sound insulation, and modern fan technology, the system operates exceptionally quietly and can therefore be installed even in densely populated residential areas or near bedroom windows. This ensures peace and quiet around your home at all times—while the heat pump reliably provides heat or cooling.
The specified sound level of 46 dB(A) describes the noise level during operation. For comparison: A quiet refrigerator operates at about 40 dB(A), while a quiet conversation is around 50–60 dB(A). At 46 dB(A), the heat pump operates at a very low noise level that is usually barely noticeable in everyday life.
The modern, minimalist design blends unobtrusively into the architecture of your home. Clean lines, high-quality materials, and a minimalist design language ensure that the system integrates elegantly into modern living environments—whether in new construction or the renovation of existing buildings. A particular advantage is the customizable color scheme. The ADAPT 2 can be ordered in various colors, allowing it to be optimally adapted to the facade, surroundings, or architectural concept. This transforms the heat pump into a deliberate design element in the outdoor space, rather than merely a technical installation.
