Why and when to undertake these works in Fribourg

7 °C. With 3233 heating degree days, heating is an essential component of local residential energy consumption. Replacing an aging fossil fuel system becomes a necessity to improve the overall energy efficiency of the local building stock.

It is recommended to anticipate the replacement of your heating system before a total breakdown. The transition to a heat pump allows for better management of consumption while aligning with the cantonal decarbonization strategy.

1 °C, the heat pump is a proven technology to meet thermal needs, provided that the sizing is adapted to local conditions and the building's insulation.

Technical choices that affect the project

Several technical options influence the performance of your heat pump installation in Fribourg. The choice between an air-to-water heat pump, capturing outdoor calories, and other systems will depend on your available space and needs.

Note that the local design temperature determines the necessary power of the heat pump to ensure constant comfort during the 79 frost days per year.

Materials and the range of the equipment also play a crucial role in durability. It is imperative to consider that external air-to-water heat pumps must respect noise limits towards neighbors to avoid nuisance. Before finalizing the model choice, also check if your plot allows for optimal integration.

Finally, overall efficiency can be improved by combining the heat pump with a photovoltaic installation, taking advantage of solar yields estimated at 1184 kWh/kWc/year in the region.

Specifics of the local building stock according to construction era

The building stock in Fribourg is varied, and each construction period imposes different constraints when replacing a heating system. For old buildings, thermal insulation is often the critical point. Before installing a heat pump, it is wise to assess the heat loss of your home.

If the building is poorly insulated, the heat pump will need to be sized to compensate for this loss, which can affect overall energy efficiency.

For buildings constructed before 1990, special attention must be paid to the potential presence of hazardous materials, such as asbestos, when removing old installations. Furthermore, checking internal distribution networks is essential.

Ensure that your existing radiators are compatible with the lower water temperature typical of heat pumps, or consider replacing them with low-temperature emitters to maximize your energy savings.

Authorizations, rules, and heritage in Fribourg

Legislation in Fribourg is governed by the Regulation of execution of the cantonal energy law (RLE), which came into force on January 1, 2024. When replacing a fossil fuel heating system with a heat pump, you are legally required to cover at least 10% of the necessary heat by renewable energies or district heating.

Measures allowing equivalent heat savings can also be accepted.

However, there are exceptions : this rule does not apply if the replacement is due to an unpredictable event, if the initial installation is less than 15 years old, or if expensive energy efficiency measures have been carried out recently.

Before taking any steps, systematically check with the municipality if your sector can be connected to the CAD Fribourg network managed by Groupe E. If in doubt about the compliance of your project or heritage specifics, contact the municipality's technical services.

Financial aid and taxation

Financial support in Fribourg is based on cantonal subsidies and the Buildings Program. These aids are specifically dedicated to the replacement of fossil systems with heat pumps. The golden rule is to submit your grant application imperatively before the start of the work.

Any installation started without prior authorization cannot benefit from any financial support.

Regarding taxation, investments in renewable energy and energy efficiency improvement are deductible from your income tax. For buildings over 10 years old, it is possible to opt for a deduction rate of 20% of the rental value, or to deduct effective costs.

If deductible costs exceed the property's income during the current fiscal year, know that this surplus can be carried forward to the next two fiscal periods. Visit the Buildings Program website for details on flat rates.

Schedule: typical project timeline

The execution of a heat pump project in Fribourg follows several logical steps. The initial phase consists of conducting a thermal audit of your building, then requesting municipal authorizations and subsidies. Once financing is validated, the choice of the installer can be finalized.

The project itself begins with the removal of the old fossil system, a sensitive step requiring strict waste management.

It is highly advisable to avoid the winter period to carry out the work, in order to limit the discomfort associated with heating interruption, although Fribourg experiences 79 frost days per year, making any planning delicate.7 °C temperature to ensure optimal operation upon commissioning.

Hydraulic and electrical connection and regulation configuration close the process, followed by a startup phase to test system performance according to real needs.

Common errors to avoid and checklist before quotes

To succeed in your project, avoid neglecting thermal insulation, as a heat pump installed in an energy-inefficient house will consume excessively. Never skip the acoustic verification before installation, especially in dense areas, to respect your neighbors.

Ensure your installer has thoroughly analyzed the existing heating network. Never sign a quote without having verified your project's eligibility for cantonal aid beforehand.

Before requesting quotes, follow this checklist : check if your neighborhood can be connected to priority district heating.7 °C. Verify that your electrical installation can support the power demand.

Finally, confirm that your current heating system is compatible with low-temperature emitters for maximum performance and a reduced bill.

Maintenance and durability

A well-maintained heat pump is the guarantee of your long-term peace of mind in Fribourg. Although these systems are robust, an annual check is recommended to verify the tightness of the refrigerant circuit and the good condition of the heat exchanger.

A clean filter and an outdoor unit free from obstacles ensure optimal heat transfer, thus reducing unnecessary strain on the compressor.

Durability also depends on your usage. Avoid short cycles by correctly setting the heating curve of your installation. Regular maintenance not only increases the lifespan of the appliance but also maintains energy performance in accordance with initial expectations.

In case of malfunction, call on qualified local professionals who know the specifics of the Fribourg climate and who will be able to intervene quickly, especially during periods of extreme cold to preserve your thermal comfort.
