Heat Pump Installation in Lisbon

Why Lisbon Is Perfect for Heat Pumps

Lisbon enjoys over 2,800 hours of sunshine per year and mild winters with average temperatures rarely dropping below 8°C. This climate makes air-source heat pumps exceptionally efficient, as they perform best in moderate conditions. In fact, a well-sized heat pump in Lisbon can achieve a Coefficient of Performance (COP) of 4.0 or higher for most of the year — meaning you get four units of heat for every unit of electricity consumed.

For expats moving from the UK, the Netherlands, Germany or Scandinavia, the savings compared to electric heaters or older gas boilers are significant. Portugal’s electricity tariffs are among the highest in Europe, so switching to a heat pump can cut your water-heating and space-heating bills by 50–75%.

Apartments in Lisbon: What Expats Need to Know

The majority of Lisbon’s housing stock consists of apartments, from historic buildings in Alfama and Graça to modern developments in Parque das Nações and Marvila. If you live in an apartment, there are a few specific considerations:

• Condomínio (condominium) approval: Most apartment buildings in Portugal have a condomínio that governs shared areas. Installing an outdoor heat pump unit on the façade, balcony or rooftop typically requires approval from the condomínio assembly. We can help you prepare the documentation and navigate this process in Portuguese.
• Noise regulations: Portuguese law sets noise limits for residential areas. Modern heat pumps are remarkably quiet (around 35–50 dB), but placement matters — especially in densely built neighbourhoods. Our certified technicians know exactly where to position the outdoor unit to comply with regulations and minimise disturbance to neighbours.
• Space constraints: Lisbon apartments often have limited outdoor space. Compact, wall-mounted heat pump units or thermodynamic systems that use a small rooftop panel are ideal solutions. For hot water only (AQS), a monobloc unit can even fit inside a utility cupboard.
• Listed buildings: If your apartment is in a heritage-protected zone (many areas in Lisbon are), there may be additional restrictions on external equipment. We’ll advise you on compliant options before any work begins.

Popular Heat Pump Services in Lisbon

Hot Water (AQS) Heat Pumps

The most popular request from our Lisbon clients. A domestic hot water heat pump replaces your old esquentador (gas water heater) or electric boiler with a system that uses ambient air to heat water. Installation typically takes half a day, and you’ll notice the difference on your very first energy bill.

Central Heating for Apartments

Many Lisbon apartments rely on portable electric heaters in winter, which are expensive and inefficient. An air-to-water heat pump connected to fan coils or low-temperature radiators provides consistent, whole-apartment warmth at a fraction of the cost.

Underfloor Heating in New Builds

Lisbon’s new-build developments in areas like Marvila, Belém and Alcântara increasingly include underfloor heating as standard. A heat pump is the ideal companion, delivering low-temperature water that underfloor systems require for maximum comfort and efficiency.

Understanding Lisbon’s Energy Regulations

Portugal requires an Energy Performance Certificate (Certificado Energético) for all properties that are sold or rented. Installing a heat pump improves your property’s energy rating significantly — often jumping one or two classes (e.g., from D to B). This not only reduces running costs but also increases property value, which is particularly relevant if you plan to rent out your Lisbon property.

Additionally, the Portuguese government offers subsidies through the Fundo Ambiental programme that can cover a significant portion of your heat pump installation costs. We handle the paperwork for you — in Portuguese, so you don’t have to.

Frequently Asked Questions — Lisbon

Do I need condomínio permission to install a heat pump in my Lisbon apartment?

In most cases, yes. Any modification to shared areas or the building’s exterior requires approval from the condomínio assembly. For indoor units (such as a monobloc AQS heat pump), approval may not be required. We’ll advise you based on your specific situation.

How much does a heat pump cost in Lisbon?

A domestic hot water (AQS) heat pump typically costs between €1,500 and €3,000 installed. Central heating systems range from €5,000 to €12,000 depending on the size of your property. Government subsidies can reduce these costs significantly. See our full pricing guide.

Is a heat pump worth it in Lisbon’s mild climate?

Absolutely. Lisbon’s mild winters are actually ideal for heat pump efficiency. You’ll save the most on hot water heating year-round, and for space heating during the cooler months (November to March), a heat pump is far more economical than electric heaters or gas.
