Data protection and security are our top priority. That's why we leave nothing to chance. To ensure the protection of your personal data and secure data transmission, we work with the latest security technologies. Your data is stored in encrypted form in a computer centre that is certified with all current industry standards. Data is therefore only passed on to third parties if you request service offers via Houzy that require this. An example of this is when you actively contact one of our broker partners. You can find further information in our T&Cs under "Our privacy policy".

Houzy is a young company and finances itself by brokering third-party services and through advertising partnerships with national and regional partners. However, you as a user always decide for yourself when you want to share what and with whom and thus always retain data sovereignty. The use of our heating comparison tool and the entire homeowner platform is therefore permanently free of charge for you. If required, you can also request concrete tradesman offers for a heating replacement from our tradesmen.

To determine which heating systems are suitable for your property, we record the address. This allows us to obtain relevant information, such as how close the house is to the district heating network or whether it is suitable for heat pumps. Some key data about the house, such as year of construction and type of house and roof, help us to classify the condition of the property. In addition, we collect some data on your current heating system as well as on heat distribution and hot water preparation. Finally, we estimate the annual energy demand with your help. You will then receive an email with online access to your digital heating comparison on Houzy.

Houzy's digital heating comparison analyses the various heating systems in Switzerland with just a few details - completely free of charge and without obligation. The analysis is based on the relevant criteria for a comparison and shows you the costs in detail. In just 2 minutes and with a few clicks, the heating calculator is ready and you can see an overview of all heating systems. We compare the installation costs as well as the running costs (maintenance costs for heating, energy costs for heating) of the heating systems, the remaining life of your current heating system, the expected life of the new heating systems, the CO2 emissions of the heating systems, the subsidies of the canton for the different heating systems and much more. The comparison is also completely neutral - Houzy is an independent platform and does not pursue any third-party interests.

The heating comparison considers the heating systems that are most widespread in Switzerland. The following heating systems are included in the comparison calculator: gas heating, oil heating, heat pump air, heat pump earth, district heating and wood. Electric heating is not included. Electric heating is still widespread in Switzerland, but it is a very uneconomical heating system. Moreover, the installation of new electric heating systems has been prohibited in all cantons since 2008.

In principle, it is always useful to know what advantages and disadvantages the various heating systems have. Especially shortly before the end of the life expectancy of your current heating system, it is relevant to know which heating system makes sense for your needs and your property. Since a heating system can fail at any time, it is especially important towards the end of the expected life of a heating system to know which heating system you will install afterwards. This will prepare you for a possible change of heating system. Especially before the winter starts, you should find out which heating system suits your needs. In addition, there is another important occasion when you should consider the heating system and possible replacement: Before buying a house or flat. If you are planning to buy a house or a flat, you should definitely analyse the heating system in terms of remaining lifetime, running costs, CO2 emissions and successor heating system.

When you replace a heating system, the first thing you have to pay for is investment costs. The existing heating system must be replaced. The new heating system is installed, which means that in addition to the costs for the heating system, there are also corresponding installation costs. The heating calculator calculates the running costs for you - divided into maintenance costs and energy costs. In the case of running costs, the energy costs in particular vary greatly between heating systems. However, the energy costs also depend on your individual energy requirements. In addition to the costs, we also include the subsidies from the relevant canton.
