Rate this post

If you live in the Lausanne area of Switzerland, that is to say in the canton of Vaud, then this article may be useful to you to get some information about the installation of your next air-to-water heat pump.

There are several aspects to consider before embarking on the installation of a heat pump, and you probably have many questions. Is the climate conducive to the installation of a heat pump? Which installer should I choose for my air-to-water heat pump in Lausanne or in the canton of Vaud? Can I benefit from a subsidy or state aid to install an air-to-water or geothermal heat pump in Lausanne? How much does it cost to install a heat pump in Lausanne ?

These are the questions that we will answer in the following lines

Is the climate in Lausanne suitable for the installation of a heat pump?

Switzerland is known for its rather cold climate, but it varies significantly depending on the region or canton considered, and even within the canton sometimes. This is the case in Vaud. Depending on whether you are north of Lausanne or on the shores of Lake Geneva, the climate can be more or less harsh. But globally the average annual temperature is always above 5°C, especially if you are in Lausanne which is on the edge of the lake and thus benefits from the mildness of the climate that the latter brings.

In fact in Lausanne the average annual temperature is around 11°C. Although in December, January and February this average temperature goes down towards 2 or 3°C, the other months of the year go up the average. The first thing we can notice is that the average temperature is always positive. The temperature rarely goes below 0°C, and therefore periods of frost exist but are not common either. If you have a whole week with temperatures below 0°C it is already rather exceptional.

These temperature considerations are important because they influence the consumption of a heat pump and its proper functioning. Of course, if it is freezing all the time, the heat pump has more difficulty to work, consumes more, can freeze, etc. and your heating becomes a pain.

But in Lausanne, this is unlikely and the heat pump can adapt very well to the climate. Even if it is very cold for a few days and your heat pump needs to be assisted by a small electrical resistance to compensate for the lack of power, the consumption due to this resistance will generally be very low because it will only be running for a few days during the year. Not enough to impact the energy savings that this heating system allows you to make all year long and especially in mid-season when the COP or coefficient of performance will be excellent.

So as far as the climate is concerned, there is nothing to report, everything is green to install a heat pump. NB: in the canton of Vaud (but not in Lausanne) it is forbidden to install air-water heat pumps above 1000m, i.e. in rather hilly or even mountainous areas. Of course Lausanne is around 400-500 m so everything is okay at this level.

First of all I will give you some advice to select a heat pump installer in Lausanne, and then there will be 3 methods to find a heat pump installer in Lausanne, whether he is from the canton of Vaud or not.

Some tips for choosing a PAC installer in French-speaking Switzerland

There are several important criteria for selecting your installer:

Its experience in the installation of heat pumps and in the building market: You can check this on the website at first, if the company has one (which is nowadays a proof of seriousness and a proof of the good communication strategy).

Reviews of the company's services: there are several sources of information on this subject. Google my business is initially a good source. The online search giant is always better at filtering out fake reviews and therefore only allows real reviews to appear on the company files. This is a good starting point. Beyond that, there are specialty sites such as Trustpilot that will be able to tell you, but nothing beats the experience of a human. You can ask an installer for references of existing installations, visit them and even ask the owner questions if they agree.

Available labels: Is the company qualified GSP or PAC System Modul. This allows you to obtain the subsidies. Otherwise it will not be possible. It would be a shame to sit on several thousand CHF.

The proximity of the installer: in the event of a breakdown or defect in the heat pump installation, how quickly will the installer be able to help you out and ensure your comfort?

Some methods to find a PAC installer in Lausanne

Several possibilities are available to you.

  1. Of course, every year the Habitat & Jardin show brings together some of the most important companies active in the field of energy renovation. Important for their visibility in the canton and in the whole of French-speaking Switzerland, this show will allow you to make your requests for quotations on the same day: grouped shooting to save time.
  2. There are sites such as devis.ch on which you can make your requests for quotes and receive up to 4 of specialized companies active on the Swiss market, but not always Swiss (sometimes French with a seat in France)
  3. Ask your neighbor if his heat pump project went well: he will give you the contact of his installer: yes, word of mouth is always a powerful vector for things to go well.
  4. Search on google: some installers present their achievements and work hard to create interesting content just for your eyes to catch your attention and offer you an installation. Their business needs activity to continue its work, and if it is of good quality, why not give them a chance to show you their know-how.
  5. Browse the list of GSP qualified companies or PAC SM : this way you are sure to find a company with a label and to get your subsidies 😉

Is there any help or subsidy from the commune or the state for a heat pump in Lausanne or in the canton of Vaud in Switzerland?

Switzerland is well developed in terms of energy renovation grants. And depending on the canton, the subsidies granted can vary but still represent a nice sum to recover if you do things properly with the right installer.

In the canton of Vaud, heat pump subsidies range from CHF 5,000 to CHF 10,000, depending on the power of your heat pump and whether or not you need to create a hydraulic network (radiators or floor heating). This applies to the replacement of oil, gas or electric resistance heating. This is the M05 grant.

These grants are part of the Vaud Building Program. They are subject to several conditions as shown in the image below, which are subject to change.

It is important to note that the grant application will be denied if you start the work before the Township approves it.
