Air source heat pump installation pricing and specifications.
1. The heat pump is installed in the patio or terrace of the property. Between the outdoor unit and the control panel, outgoing and return water piping is installed. At this point, it is checked that the return pipe has an incorporated filter to prevent impurities from entering that could damage the heat pump.
The heat pump is installed in the patio or terrace, connected via supply and return pipes to the components panel. It's essential to verify that the return pipe includes a filter to protect the equipment from impurities. This initial step is critical in aerothermal installation, with basic costs from 3,500 €.
2. The equipment is connected to the electrical grid through the power line. This way, two power lines connect the outdoor unit with the equipment components. The equipment has the advantage of having its own independent electrical panel separate from the property's electrical panel.
The equipment is connected to the electrical grid through dedicated power lines from the outdoor unit. The main advantage is that the aerothermal system has its own independent electrical panel, preventing overloads on your home's existing electrical installation.
3. A domestic hot water tank is installed to supply the domestic hot water circuit which, in turn, provides service to the faucets and showers in the property. An expansion vessel is installed in the water return from the property to absorb excess pressure and reduce temperature. Similarly, a valve is placed in the return pipe to maintain constant pressure in the circuit.
A DHW tank is installed to supply hot water to taps and showers. An expansion vessel absorbs excess pressure, while a valve maintains constant circuit pressure. This configuration is essential in aerothermal systems, with investments in standard ranges between 6,500 € and 9,500 €.

4. The installation can be complemented by coupling a recirculation pump to the DHW tank that facilitates water discharge.
Adding a recirculation pump to the DHW tank improves hot water delivery, ensuring immediate availability at taps and showers without delays. This optional enhancement increases home comfort with moderate additional cost in aerothermal installations.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Required heating capacity
The capacity of the air source heat pump (measured in kW) varies depending on the area to be conditioned and heating needs. Higher capacities mean more expensive equipment and therefore higher prices per m².
Type of installation (radiators vs. underfloor heating)
Underfloor heating installation requires more civil work and piping than connection to existing radiators, significantly increasing the total cost per square meter.
Civil work and necessary renovations
The condition of the property, need to remove walls, create channels for ducts, or adapt the current structure directly impacts the final installation budget.
Geographic location and accessibility
Hard-to-reach areas, upper floors without elevators, or regions with higher labor costs increase the installation price per m² compared to urban areas with better accessibility.
What is air source heat pump technology and how does it work?
Air source heat pump installation pricing and specifications.
Air source heat pump technology is a renewable energy system that, through a thermodynamic cycle, captures energy from the air using an outdoor unit and converts it into cooling or heating to meet heating, cooling, and domestic hot water needs in an economical and environmentally friendly way. It is the most efficient climate control system on the market as it can extract up to 75% of energy directly from outdoor air.
How much does an air source heat pump installation cost?: explanation
Air source heat pump installation pricing and specifications.
Air source heat pump operation is based on a heat pump system. Using a thermodynamic cycle and refrigerant gas compressed at low temperature, it extracts heat from outdoor air. The refrigerant circulates through a circuit with the help of a compressor, converting gas to liquid. When the gas changes state to liquid, the gas releases its heat to the air or hot water in the heat exchanger, which transfers this energy. This is how air source heat pumps work.
The range of air source heat pump installation prices is wide because the price depends on the size of the property, the power of the device, or the type of heat pump installed.
*These prices are indicative. The final air source heat pump price will depend on the m² of the property.
The factor that most influences the installation price of an air source heat pump for heating and domestic hot water is the size of the property, as it determines the required heat pump power, the system size, and the length of hydraulic installation and square meters of radiant floor needed. Below, we show you, as a guide, the different air source heat pump prices for heating and hot water according to the m² of the property:

Frequently Asked Questions
How much does it cost to install an air-source heat pump per square meter in 2025?
The average installation cost for air-source heat pumps in Spain ranges between 150€ and 300€ per m² of climate-controlled space, depending on the system type and installation complexity. For a typical single-family home of 150 m², the total cost is around 22,500€ to 45,000€ including the outdoor unit, distribution circuits, and thermal emitters. Prices can vary significantly depending on the autonomous community, installation accessibility, and whether additional renovation work is required.
How long does it take to install an air-source heat pump system?
Installing air-source heat pump in a typical single-family home requires between 5 and 10 working days, though this timeline may extend if piping distribution renovations or structural adaptations are needed. In apartments or homes with limited space, installation can be completed in 3 to 7 days. The total time from budget request to system startup is usually 4 to 8 weeks, including administrative procedures and permits.
What is included in the air-source heat pump installation price?
The installation price generally includes the outdoor unit (air-source heat pump), refrigerant piping, hydraulic distribution circuits, radiators or radiant floor heating, smart thermostat, and installation labor. Structural renovation costs, masonry work, additional thermal inertia systems, or complementary solar equipment are typically not included. It is recommended to request detailed quotes that specify exactly which components and services are covered.
How do I choose a certified air-source heat pump installer?
Verify that the installer holds RITE certification (Thermal Installations Regulation) and has proven experience with air-source heat pump systems with references from completed projects. It is advisable to request multiple quotes (at least 3) from local installers and compare not only the final price but also the type of equipment proposed, warranties offered, and after-sales service. Check that the company is registered in the appropriate registers of your autonomous community and has liability insurance.
Do I need special permits or procedures to install an air-source heat pump?
Yes, air-source heat pump installation requires prior notification to local authorities or authorization in some municipalities, especially in new construction homes or when significantly modifying the existing heating system. A technical inspection following RITE regulations is also mandatory after installation, with an additional cost of 150€ to 300€. In homeowner associations, prior approval from the assembly is required, which can add 2 to 4 weeks to the overall process.
