Heat Pump Installation in Vevey: A Comprehensive Guide for Homeowners

The city of Vevey, which holds the GOLD Energy City label, pursues an ambitious climate policy.3 °C and approximately 22 frost days per year, the local building stock requires high-performance systems.

Replacing a fossil fuel heating system with a heat pump allows you to sustainably reduce your carbon footprint while enhancing the value of your real estate in a municipality that actively encourages renovation through the 'Vevey Rénove' program.

The ideal time to act is generally when your current boiler reaches the end of its life. By planning ahead, you avoid hasty decisions.

Additionally, it is crucial to first verify whether your neighborhood can be connected to the Vevey district heating network, managed by Groupe E, as a connection obligation may apply according to Art. 25 para. 2 LVLEne for major transformations.

The choice of heat pump system depends mainly on the configuration of your home. Air-to-water heat pumps are common but require particular attention regarding noise, as they must comply with limits towards neighbors.

A precise thermal study allows for the determination of the necessary power while taking into account the local design outdoor temperature.

There are different quality levels and options, such as coupling with photovoltaic panels, favored by a global irradiation of 1352 kWh/m²/year in Vevey. The use of geothermal probes or more compact systems will depend on your available space and the nature of your soil.

Regardless of your choice, ensure that the equipment is sized for the region's specific climatic conditions to optimize the seasonal performance factor of your future installation.

Vevey has a diverse building heritage. For buildings constructed before 1990, particular attention must be paid to the potential presence of pollutants, such as asbestos, during demolition or transformation work.

Before installing a heat pump, it is recommended to carry out an energy audit to assess whether your current insulation allows for optimal operation of the low-temperature system.

The Vevey district heating network offers an interesting alternative for certain buildings, especially if a major thermal renovation is technically difficult to achieve. In ISOS-listed areas, as is the case for a large part of the city center, aesthetic and conservation constraints may limit exterior modifications.

It is therefore essential to check the specific rules of the communal land use plan for your area before starting work that impacts the exterior appearance of your building, in order to avoid any intervention that does not comply with the site requirements.

In the canton of Vaud, the installation of a heat pump is generally subject to the simplified building permit procedure. For air-to-water or air-to-air models, noise nuisances must be strictly taken into account to ensure respect for neighbors.

If your building is located in a protected zone, particularly within the ISOS perimeter, strict rules apply to preserve the historical appearance of the municipality.

For any intervention that modifies the exterior appearance, an authorization may be required. We advise you to contact the municipality of Vevey beforehand to confirm whether your project falls under a permit exemption or requires a formal application.

The goal is to reconcile energy performance with heritage protection requirements. Never neglect this step, as compliance with communal regulations is essential to avoid subsequent complications during the implementation of your energy project.

The replacement of a fossil fuel or electric heating system with a heat pump entitles you to subsidies via the 'Buildings Program'. The amount varies according to the type of pump and its power. It is mandatory to submit your grant application before starting the work, otherwise you may lose your right to this aid.

This step is a priority to reduce the cost of your investment.

From a tax perspective, investments intended to save energy are 100% deductible. In the case of high costs, the balance can be carried forward to the two following tax periods if the expenses cannot be fully taken into account in the year they were incurred.

Note, however, that by opting for this deduction, you cannot benefit from the flat-rate deduction for the maintenance of your property that year.

Consult your tax administration regarding the conditions for combining these deductions, as the choice depends on your personal situation and other work carried out on your property.

The execution of a heat pump project follows several structured steps. Everything begins with a feasibility study and the choice of the installer, followed by the submission of the necessary permit applications to the municipality. Once permits are obtained and subsidies approved, work can begin.

It is preferable to plan the installation outside of periods of extreme cold so as not to penalize the thermal comfort of your home during the transition.

The project itself generally includes decommissioning the old installation, connection work, installation of the outdoor unit, and setting up the regulation. The total duration will depend on technical complexity, especially if hydraulic distribution work needs to be adapted.

A final commissioning is essential to verify the performance of the installation and its proper operation. Anticipate these steps several months in advance to be ready before the winter season.

To make your project a success, avoid neglecting the insulation of your home, as a heat pump will be less efficient in a poorly insulated building. Never choose an oversized capacity, which would lead to premature wear of the compressor and unnecessary consumption.

Also, make sure to carefully check the noise level of the outdoor unit so as not to disturb the tranquility of the neighborhood, in accordance with local recommendations.

Before requesting quotes, check if your neighborhood can be connected to the priority district heating system. Request several comparative quotes detailing costs and services. Verify that the installer provides a thermal study based on Vevey's design temperatures.

Ensure that the subsidy application is ready to be sent before signing any contract. Finally, list your precise needs for domestic hot water and heating, and do not forget to include future maintenance aspects in your discussions with the providers.
