Heat pumps

With the earth - not against it

Did you already know?

Around 40 % of Switzerland's total CO2 emissions are caused by heating in private households. Quite a lot, isn't it? By installing a heat pump, you can save 95% of your CO2 emissions and actively contribute to achieving the Swiss climate goals. If you replace your oil heating with a heat pump, you also make yourself independent of suppliers and fluctuating oil prices. On top of that, you also save money because heat pumps are more cost-efficient in the long run compared to other heating systems.

When choosing our partners, we focus on manufacturers who have developed heat pumps with the lowest possible noise emissions - so that not only you, but also your neighbours sleep well. Space for a heat pump is also no problem - usually, when an oil heating system is removed, space is even freed up because the oil tank is no longer used. Contact us and we will find your solution.

Understanding heat pumps

A heat pump works like an inverted refrigerator: it extracts energy from the environment and converts it into heat for heating and hot water. It is powered by electricity but is very efficient because it only draws a quarter of the energy from the electricity and the rest from the environment.

Heat source

The heat pump extracts energy from its environment - the air or the ground.

Heat production

Inside the heat pump, electricity is used to generate heat from this energy.

Heat distribution

The heat gained in this way is transferred to the heating system.

Types of heat pumps

Depending on the environment, two systems are available:

 A. Air-to-water heat pump

The most popular technology! Air-to-water heat pumps use energy from the air to generate heat. They are inexpensive and easy to install. Depending on your living situation, they can be installed outside, inside or in combination - depending on your personal needs.

B. Ground source heat pump

This technology is the most cost-intensive at the beginning, but scores with the lowest follow-up costs during the entire service life. The costs are mainly incurred by drilling into the ground. This borehole must be approved by the municipality - but we take care of the entire administrative part for you.

Advantages and disadvantages of indoor and outdoor installation

Indoor installation

+ Hardly any noise pollution
+ Can be implemented for both systems

- Space requirement
- Air duct through house wall

Outdoor installation

+ Easy to retrofit
+ Minimal penetration of the building envelope
+ Ideal installation if compact and possible directly on the building

- Visual appearance due to outdoor installation
- Low noise emissions
- External heating water pipes
- Only feasible for air-to-water heat pumps

Split units 

+ Low space requirements indoors

- Exterior coolant lines (if not directly attached to the house)
- Only feasible for air-to-water heat pumps

Installing a heat pump

How to get your own heat pump in just four steps.

Costs for a heat pump

The total costs depend mainly on which heating system has to be removed in order to install a heat pump and which heat pump you choose. Good solutions are available from around CHF 30,000.

  • Since heat pumps have been proven to save more than 95% of CO2 emissions from heating, the installation of heat pumps is financially supported. Cantons and municipalities have worked out different models. You can find a list of the subsidy programmes in your area at Energiefranken.

    You can also benefit from tax advantages: Depending on the situation - new construction or renovation - you can deduct up to 100% of the total costs from your taxes. The best thing about it: depending on the tax progression, this can 

  • In addition to ambient air, a heat pump also uses electricity as an energy source. The increased electricity demand is generated most sustainably and cheaply with a solar system. This combination is the most favorable solution in the long term and promises independence from external suppliers. Contact us and we will find a suitable option for you.

Fact check


  • There are three different possibilities for placing a heat pump: externally placed, internally placed and a combination of internally and externally placed heat pumps, so-called split systems. Criteria for the respective installation types are, for example: legal regulations (e.g. noise protection), conditions of the surroundings (e.g. distance to neighboring houses and roads) and the wishes of the building owner regarding space. We will be happy to advise you if you have any questions.

  • The heat pump also works in freezing cold. It only becomes critical at a range of -20 degrees. In the rare event that it is that cold, the heat pump can also heat purely electrically - so you will certainly never freeze.

  • We offer you the guarantee according to the SIA standard: 2 years on the device and 5 years on hidden defects.

  • There is no drop in performance over the entire service life of the heat pump. On the contrary - modern heat pumps in particular can themselves be better adjusted over time and thus increase their overall efficiency. Similar to a refrigerator, however, there can be wear and tear on moving parts. We will be happy to provide you with more detailed information about the models of the various manufacturers in order to find the best quality for you.

  • Depending on the building's insulation, the severity of the winter and the desired indoor temperature, the average electricity consumption of a heat pump is around 4000-6000 kWh. On average, this means that the electricity demand doubles, but it also eliminates oil and gas altogether.

    If you also opt for a solar system, you can feed the heat pump with your own electricity. This greatly increases the financial advantages that a solar system offers anyway. In addition, you are particularly independent with this combination.

  • Most heat pumps have an integrated emergency heating system that comes into play in the event of a failure. The electric heater then generates 1:1 heat from the electricity, instead of the 4:1 efficiency with a heat pump.

  • Only the refrigerant, which is similar to the one in a refrigerator, is not entirely harmless. Heat pumps should therefore be recycled professionally.

  • A heat pump should always be recycled professionally. The fee for this is already paid automatically at the time of purchase and thus the heat pump can be disposed of without further costs.


  • The building envelope does not have to meet any specific requirements in order for a heat pump to be installed. However, there are two points you should bear in mind:

    1. The efficiency of the heat pump is only as good as the insulation of the house.
    2. There should be radiators with as large a surface area as possible (e.g. underfloor heating), due to the low flow temperature of the heat pump.
  • Ideally, the house should be well insulated so that the energy can be produced cleanly and used efficiently. Windows, roof, façade and basement floor should be insulated. Ideally, the house's own electricity is produced on the roof and powers a heat pump, among other things - and perhaps one day an electric car.
