The right heat pump for your living situation
Heat pumps are an efficient and environmentally friendly heating solution which today are seen as the key to a sustainable future. But which type of heat pump is best suited to your specific living situation? Find out more about the criteria for deciding below.
Heat pump types
There are three ways that heat pumps use natural energy as a heat source. All three operate according to the same principle: the pumps extract heat from the air, the ground or water and release it where it is needed, such as in your home. Each type of heat pump offers its own individual benefits. Which heat pump is right for you will depend on your own circumstances and needs.Wärmepumpentypen im Vergleich

Which heat pump is right for you?
Every home is different. The heat pump that will efficiently and sustainably meet the heating requirements of your single-family home or apartment building depends on various factors. Since each single-family home or apartment building has its own demands, requirements and environmental conditions, a range of potential solutions are available.

Heat pumps for a single-family home: cost-efficient and flexible
Choosing the right heat pump for your single-family home is crucial in terms of being able to heat your home efficiently and cost-effectively. Compared to apartment buildings, single-family homes often occupy less land and require less heating. In single-family homes, criteria such as noise levels and how unobtrusively a pump can be installed in the house or garden are decisive. It is important to consider the space requirements and installation conditions.An air/water heat pump is one potential alternative heating solution for single-family homes. These pumps use ambient air for heating and can be installed inside or outside the house. This type of heat pump can be installed relatively quickly and economically. The following CTA products are suitable air/water heat pumps.Geothermal heat pumps, which draw their energy from the ground, are also an appropriate option as a heat pump in a single-family home. Geothermal probe drilling is cost-intensive, which makes them somewhat more expensive to purchase, but their source temperature remains constant over 20 years of operation, making them the most cost-effective heating system. The following CTA products are brine/water heat pumps.A groundwater heat pump can also be used in single-family homes. Although they are cost-effective to operate, the high investment costs required and the time-consuming procedure for obtaining permission make groundwater heat pumps less appealing than other heat pumps for single-family homes.At the end of the day, the right heat pump for your single-family home will depend on your own personal circumstances and requirements. We therefore recommend that you seek professional advice from us or from your regional heating engineer.Heat pumps for apartment buildings: scalable and with a focus on efficiency
Choosing the right heat pump for an apartment block is crucial to ensure efficient operation, economic benefits and long-term living comfort. Although the basic decision criteria are similar to those for a single-family home, a multi-family home requires significantly higher heating outputs, which must be given special consideration during planning. In our product finder, you can narrow down by heating output requirement (kW). At the end of the day, the right heat pump for an apartment building will depend on the residents’ personal circumstances and requirements. We therefore recommend that you seek professional advice from us or from your local heating engineer.

Potential heat sources and legal requirements
Each canton and municipality has its own regulations for zoning and construction. It is important to be familiar with these. There may also be stipulations on minimum distances between an air/water heat pump or a geothermal probe for a geothermal heat pump and the neighbouring property. These regulations will tell you which types of heat pumps can even be considered for your single-family home or apartment building.Spatial conditions indoors and outdoors
If drilling is possible in principle [↗], you need to check whether there is sufficient space for it. If you plan to install a geothermal probe heat pump or a groundwater heat pump, it must be possible to bring large or smaller drilling equipment onto the land, potentially with the help of a crane. The length of the pipe leading to the heating room must also be taken into account. The same considerations apply to air/water heat pumps installed outdoors: the closer the exterior device can be placed to the heating room, the more cost-effective it will be, because the hole dug will not need to be so deep. It should be determined how much room there is in the heating room inside the house for the heat pump itself, not to mention for accessories like hot water or buffer tanks. It is also important to clarify how the device will be brought inside. Depending on their model, some CTA pumps can be disassembled while others need to be brought in in one piece.Heating output required
The size of the heat pump will be determined by the heating output required. In other words, it depends on how much energy your single-family home or apartment building needs. It helps to know the average energy consumption over the past three to five years (number of litres of oil, volume of gas/wood, units of electricity consumed). When calculating the dimensions of a heat pump system, it is also important to know the surface area of the space to be heated (in m2).Structural considerations
The condition of the building is also a determining factor in the type of heat pump and the accessories. If the building is well-insulated (roof, façade, windows) – and this is always something we recommend ensuring as a first step – it will require less heating and thus a different size heat pump. If the building has a photovoltaic or solar thermal system or if there are plans to install one, this must also be taken into consideration when planning an appropriate heat pump system. Something else important to know when planning is whether underfloor heating or radiators distribute the heat throughout the house. This will determine how high or low the flow temperatures need to be.Financial resources
Although heat pumps are more expensive to buy than fossil fuel heating systems, their maintenance and energy costs are significantly lower. This is mainly due to the fact that heat pumps are largely operated with free energy from water, air, or the ground. Heat pumps also require relatively little maintenance. While, in the short term, heat pumps are therefore somewhat more expensive, they harvest their cost benefits in the medium and long term. Find out more about the costs in this article.Good to know: cantons and municipalities are promoting the replacement of fossil fuel heating systems with solutions using renewable energy. Visit energiefranken.ch to find out more about which subsidies are available in your municipality. Also good to know: investments in heat pump heating systems can be spread over three tax periods.
