Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
A standard non-condensing boiler is usually older and less efficient.
For your renovation projects in Pully, RegBL figures provide essential benchmarks. With 6 buildings identified as protected heritage out of 126 known properties, contacting the municipality early is vital to secure your permits. The median house volume is 1165 m3 according to SIA 416, which is crucial for scaling your insulation works or heating system upgrades. Please note that data coverage is partial, as the volume is only measured for 126 houses out of 612 recorded in the municipality. These metrics help you assess the scale of your construction work and accurately estimate renovation costs for your home.

The municipality of Pully, having achieved the Energy City label in 2017, is actively committed to the energy transition.6 °C and significant heating needs, replacing fossil fuel systems is a priority to reduce your ecological footprint.
The local energy strategy, supported by the Ecowatt program, encourages owners to favor renewable solutions.
The ideal time to consider these works is often during a comprehensive renovation of the building envelope or before an irreparable breakdown of your current boiler.2 °C, a properly sized heat pump ensures optimal thermal comfort throughout winter.
Anticipating this change also allows for better integration of noise constraints related to outdoor units.
The choice of heat pump system is crucial for the performance of your installation in Pully.
Air-water models are common, but it is important to check if your neighborhood is connectable to the priority district heating network, particularly in the south of the municipality.
2 °C to ensure stable heating without excessive reliance on electrical backup.
Beyond the type of heat source, the quality of components and the product range influence the seasonal performance factor. Options such as summer cooling or home automation connectivity increase comfort but require prior consideration.
Furthermore, outdoor air-water heat pumps require special attention regarding noise levels towards neighbors, a key factor in validating the technical location on your plot.
Energy renovation in Pully must take into account the varied building typology. For constructions dating from before 1990, special attention must be paid to the potential presence of asbestos in old heating networks or insulation.
Before installing a heat pump, it is strongly recommended to check the condition of your facade insulation and windows, as a heat pump will be all the more efficient as the heat demand of the building is controlled.
If your building is old, compatibility with a low-temperature heating system is a major issue. Replacing existing radiators with more efficient models or installing underfloor heating may be necessary to optimize performance.
It is therefore essential to evaluate the consistency of the current installation with the requirements of the heat pump to avoid unnecessary energy overconsumption after commissioning.
This guide does not establish a permit exemption. If your building or area is protected, check the constraints specific to your project.
To reduce the cost of your energy transition, subsidies are available through the Building Program, supported by the Confederation and the canton of Vaud.
The amount, which varies according to the type and power of the heat pump, represents significant help for replacing fossil fuel or electric heating.
It is crucial to submit your subsidy application before starting the work, otherwise you may lose your right to financial aid.
Regarding taxation, the canton of Vaud allows the deduction of 100% of costs related to investments intended to save energy.
These expenses, which concern the replacement of obsolete installations, can be carried forward to the two following tax periods if your net income is insufficient in the year of the investment.
If you already benefit from a public subsidy, only the part you actually finance is deductible. Be sure to keep all invoices and supporting documents to facilitate your tax returns.
The execution of a heat pump project in Pully follows a structured process. The first phase consists of establishing an energy assessment to correctly size the unit, taking into account the 44 annual frost days.
Once the professional is selected, the subsidy file is submitted before any material is ordered. Then, the simplified authorization, if necessary, is obtained from the competent services.
The construction work itself begins with the removal of the old boiler, followed by the installation of the new unit and hydraulic and electrical connections. Ideally, plan these works outside of periods of extreme cold to avoid being left without heating.
Commissioning includes fine-tuning the controls, which is essential to maximize the system's performance and ensure long-term thermal comfort in your home in Pully.
Never neglect the importance of a prior energy assessment to avoid oversizing or undersizing your heat pump. Ensure that the location of the outdoor unit will not generate excessive noise for your neighbors.
Systematically check if the Pully district heating network is accessible, which could be a wiser alternative. Obtain at least three detailed quotes and compare the services, not just the total price.
Always confirm that your heating engineer holds a recognized certification for heat pump installation.
Before signing, check this checklist : have I submitted my subsidy application? Is my installation compatible with the current radiator system? Have I checked the constraints related to the exterior appearance of my building?
Has the company included commissioning and regulation training in the quote? These precautions will protect you against technical or administrative surprises throughout the project.
