Houzy Heating Calculator – Comparison of heating systems

With the acquisition of a new heating system there are numerous factors to consider, the central ones are thereby the following: Costs for the acquisition as well as assembly of the heating, running costs, life span and the environmental compatibility. Besides, individual factors also play a role: Is your real estate suitable for heat pumps? Is your home close to the district heating network? What is your budget for the purchase of a heating system?

The Houzy Heating calculator compares the heating systems oil, gas, wood, heat pump (earth & air) as well as district heating. Besides the costs, we also take into account your individual energy requirements, the expected remaining service life of your current heating system and, of course, the CO₂ emissions of each heating system.

When changing the heating system, don't forget the global renovation needs

In particular with the renewal of a heating system, the further renovation need of the real estate should be examined. For example, it may be worthwhile to renovate the facade at the same time as the heating system is replaced.

However, other renovation measures could be combined and thus you could save a lot of money. Houzy allows you to fully verify the renovation needs of your property. And, by bundling renovation projects together, you'll enjoy peace of mind for longer!

Houzy checks the general renovation needs of your property so that you can plan renovations wisely.

I almost renovated my kitchen without renovating the plumbing, which would have cost me thousands of francs two years later. Luckily, HouzyCheck avoided that!

FAQs – Answers to Houzy

Why is the heating comparison free of charge?

FAQ arrow

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.

What information does Houzy need for the heating comparison?

FAQ arrow

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 MyHouzy.

What are the advantages of using the Houzy heating calculator?

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.

Which heating systems are compared in the heating calculator?

FAQ arrow

The analysis compares 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.

When is a heating comparison important?

FAQ arrow

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.

Which costs of the heaters are compared with each other?

FAQ arrow

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. Then we calculate 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.
