Aerothermal installers in Girona

At Fotovol we install aerothermal heating and cooling systems with our own engineering and complete legalization. We do not sell standard equipment: we analyze your home, calculate real thermal loads and design the system to work with maximum performance from the first winter.

We integrate existing radiators or underfloor heating, adjust the climate curve and manage all the technical procedures. We also combine aerothermics with solar panels to minimize the purchase of electricity from the grid.

Aerothermal installation company in Girona and its province

As an aerothermal installation company in Girona we work with technical criteria adapted to the real climate of each area of the province. It is not the same to dimension a system in the humid and saline environment of the Costa Brava than in the colder climate of the interior or Ripollès, where the thermal demand in winter is higher.

In coastal towns such as Palamós, Roses or Cadaqués, we pay special attention to the location of the outdoor unit and the protection against environmental corrosion. In inland areas such as Olot or Ripoll, the power calculation and the defrosting strategy are decisive to maintain seasonal performance.

Each installation starts with a previous technical visit where we evaluate:

Optimal location of the outdoor unit (noise, ventilation and performance).
Compatibility of existing emitters (radiators, underfloor heating or fan coils for summer cooling).
Actual level of thermal insulation and possible energy losses.
Heating, cooling and DHW demand according to use profile (primary residence or second home).

We do not size by standard square meters. We calculate real thermal loads to avoid oversizing that reduces efficiency and increases electricity consumption.

We install aerothermal energy in Girona city and metropolitan area (Salt, Sarrià de Ter, Vilablareix), Costa Brava and Empordà, as well as in the interior of the province, adapting each project to the specific climatic conditions of the area.

Why choose Fotovol as aerothermal installers in Girona?

The real performance of an aerothermal installation does not only depend on the brand of the equipment, but also on the design, sizing and initial configuration. In Fotovol we work with our own engineering and a defined technical process, with installations carried out throughout the province of Girona, both in homes and in companies.

Our approach combines practical experience, technical calculation and post-commissioning follow-up. Each project is sized individually, not by standard estimates.

Actual thermal calculation, not estimates per square meters

We analyze thermal losses, orientation, insulation, existing emitters and DHW demand. We dimension the power according to real load to avoid oversized equipment that reduce efficiency and shorten useful life.

Optimization of SCOP and climate curve

We configure the climate curve according to the climate of Girona (coast and inland) to maximize seasonal performance and minimize unnecessary consumption. We adjust parameters after start-up to guarantee stable operation.

Compatibility with existing radiators

It is not always necessary to change emitters. We evaluate thermal flashovers, return and emitter surface before recommending high temperature.

Legalization and regulation without complications

We include technical report, compliance with RITE and CTE DB-HE, and processing before the Institut Català d’Energia (ICAEN) when applicable, as well as active aid management.

Leading brands and professional configuration

We work with Daikin, Mitsubishi Electric, Panasonic and Vaillant, adjusting defrost parameters, 3-way valve, anti-legionella and real modulation to optimize performance.

Follow-up, monitoring and agile technical response

We install systems with app and telemetry to verify consumption and make fine adjustments. After the technical visit, we deliver a detailed proposal in a short period of time, with a closed budget and no surprises.

More than 25 years developing and installing air conditioning and energy efficiency solutions in Girona, accompanying families and communities in their energy transition.

Types of systems we install

What real performance can you expect from an aerothermal installation in Girona?

The efficiency of a heat pump is not the same in all areas or in all homes. The actual performance depends on the local climate, the type of emitters and the insulation level of the building. In Girona, conditions change significantly between coast and inland, and this influences the SCOP (seasonal coefficient of performance).

Yield according to Girona climate zone

In Costa Brava areas, with more moderate winter temperatures, seasonal yields tend to be higher and more stable.

Indoors (Olot, Ripoll and colder areas), the machine works with higher thermal demands, which requires:

Correct sizing.
Fine adjustment of climatic curve.
Optimized defrost strategy.

A well configured unit can maintain seasonal yields between 3 and 4 (for every kWh of electricity consumed, it produces 3-4 kWh of thermal energy), provided that the system is properly designed.

Existing radiators vs. underfloor heating

The type of transmitter is decisive:

Underfloor heating: works at low temperature (30-35 ºC), which maximizes performance.
Low temperature or oversized radiators: they can work properly without changing the installation.
Small conventional radiators: may require prior analysis to avoid loss of efficiency.

It is not always necessary to install high temperature (70-75 ºC). This decision should be based on thermal calculation, not on commercial intuition.

Impact of insulation on actual savings

A well-insulated house needs lower supply temperature, which increases the performance and reduces electricity consumption.

In rehabilitation, savings often depend not only on the machine, but also on:

Carpentries.
Thermal envelope.
Thermal bridges.

That is why we carry out a preliminary study before quoting.

Does it work well in winter with cold and tramontana?

Yes, as long as:

The equipment is properly sized.
The outdoor unit is properly located.
The defrost strategy is correctly configured.

Today's heat pumps are designed to operate even in sub-zero temperatures, but the performance depends more on the design than on the data sheet.

Service areas in Girona

We perform aerothermal installations in Girona city and throughout the province, adapting each system to the climate and type of housing in each area.

In all cases we make a technical visit beforehand to guarantee a correct dimensioning and a budget adjusted to the reality of the house.

We work in:

Girona city and metropolitan area (Salt, Sarrià de Ter, Vilablareix), where apartments and regular houses with heating and cooling needs predominate.

Costa Brava and Empordà (Palamós, Platja d’Aro, Roses, Cadaqués), taking into account humidity, saline environment and second homes.

Interior and cold areas (Olot, Ripoll, Banyoles), where thermal calculation and optimization of defrosting are key to maintaining performance.

Price to install aerothermal in Girona (approximate ranges and influencing factors)

The cost of an aerothermal installation in Girona depends on multiple factors such as the size of the house, the type of existing emitters, the thermal insulation, the complexity of the installation and whether it is integrated with solar panels or support batteries. Below we give you some orientative ranges, but we always recommend a previous technical study for a closed budget.

70-100 m² apartment

In medium-sized apartments (70-100 m²) with compatible existing emitters (low temperature radiators or fan coils), the installation cost is usually in an indicative range:

From 8.000 € to 12.000 €.
Includes: equipment supply, installation, commissioning and RITE legalization.
May vary according to existing emitters, accessibility and climate curve settings.

Single-family house of 120-180 m² (120-180 sq.m.)

For single-family homes with larger floor area and/or underfloor heating system, the ranges are usually:

From 12.000 € to 18.000 €.
Includes: hydraulic design, auxiliary installations and commissioning.
Depending on emitters and system adaptation, additional work may be required.

Dwelling >200 m²

In large houses or with high demand for DHW and air conditioning, the indicative budget is:

From €16,000 to €20,000 or more
Includes: complete design, adjustments for high demands and certified commissioning.
This range can grow if integrated with hybrid or tertiary systems.

Factors influencing price

The final cost depends on several technical factors that are not always apparent at first glance:

Home insulation: poorly insulated homes require more power and thermal adjustments.
Type of emitters: radiant floor vs. conventional radiators (low vs. high temperature).
Installation accessibility: height, outdoor space, hydraulic paths.
Integration with solar panels: improves performance and reduces operating costs.
Batteries to support PV: If batteries are installed for the PV installation, this may influence the total cost to see battery service.
Legalization and formalities: technical reports, RITE, ICAEN and aid documentation.
Complementary emitters: installation of fan-coils, inter-accumulators or buffer tanks.

All these factors are assessed in a previous technical visit to ensure that the budget is real and closed, with no surprises.

Grants and subsidies for aerothermal energy in Girona

The aerothermal installation can be eligible for incentive programs when there are active calls, such as subsidies linked to energy efficiency or Next Generation funds. In Fotovol we analyze each case and manage the necessary technical documentation before the Institut Català d’Energia (ICAEN) when applicable.

Aerothermics + solar panels in Girona: intelligent self-consumption

The combination of aerothermal and solar panels is one of the most efficient solutions to reduce the energy bill in Girona. The heat pump needs electricity to operate, and if that electricity is generated on your own roof, the savings are multiplied.

We design integrated systems where photovoltaic production and thermal demand work in coordination, optimizing the use of solar energy during peak generation hours.

Intelligent surplus management

Instead of dumping all the excess solar energy into the grid, we configure the system to use the surplus in the home itself.

Programmed activation of the heat pump during solar hours.
Prioritization of DHW production when there is a surplus.
Optimization of consumption to reduce network purchases.

This makes it possible to transform solar energy into thermal comfort, not only into economic compensation.

Buffer tank and DHW in solar hours

The buffer tank and the domestic hot water storage tank can be used as a thermal battery. During peak solar production hours, the system raises the temperature of the tank to store energy in the form of heat.

Greater use of photovoltaic production.
Reduced dependence on the power grid at night.
Thermal stability in the house.

This strategy is especially efficient in single-family homes and second homes on the Costa Brava.

Actual reduction of purchase from the network

When the aerothermal and self-consumption systems are correctly dimensioned, the purchase of electricity from the grid can be significantly reduced.

Lower exposure to electricity price increases.
Greater energy independence.
Improvement of the energy certification of the property.

In many consumption profiles, the combination of aerothermal and solar panels can achieve very low energy bills, provided that the technical design is correctly calculated from the beginning.

What you should know before hiring aerothermal installers in Girona

Not all aerothermal installations offer the same performance. The difference is usually not in the brand of equipment, but in the design, sizing and initial configuration.

Before hiring aerothermal installers in Girona, it is advisable to review these common mistakes that can directly affect consumption and comfort .

Common mistake: wrongly dimensioned power

Sizing the heat pump only by square meters is one of the most frequent mistakes.

Oversized equipment constantly cycles, loses efficiency and reduces its useful life.
An undersized equipment works forced and increases the electrical consumption.

The calculation should be based on actual thermal losses, orientation, insulation, existing emitters and DHW demand. Without a previous thermal study, the budget is only an estimate.

Common mistake: not fitting the climate curve

The climatic curve determines the flow temperature according to the outdoor temperature. If not correctly adjusted to the Girona climate, the system may consume more than necessary.

Too high supply temperature = lower seasonal performance.
Incorrect setting = less comfort and higher electricity costs.

A correct configuration allows the installation to work in a modulated and efficient way during the whole winter.

Common mistake: selling high temperature without prior study

High-temperature aerothermal energy can be a valid solution in certain cases, but it is not always necessary or the most efficient.

Many radiators operate correctly at low temperatures if they are properly sized.
Operating at 70-75 ºC reduces performance compared to low temperature systems.

Before recommending high temperature, it is essential to evaluate thermal flashovers, return and actual condition of the emitters.

A well-designed installation from the outset avoids cost overruns, improves seasonal performance and ensures real savings in the long term.

Real advantages compared to gas or diesel in Girona

Many homes in Girona still operate with natural gas or oil boilers. Aerothermics is not only a renewable alternative, but a more efficient and stable solution against the volatility of fossil fuels.

Energy savings in the medium and long term

While a gas or oil boiler converts fuel into heat with limited performance, aerothermal energy multiplies the electrical energy consumed thanks to its heat pump operation.

For every 1 kWh of electricity consumed, it can generate between 3 and 4 kWh of thermal energy (depending on design and climate).
Usual reduction in consumption compared to heating oil.
Greater stability in the face of fuel price increases.

Reduced maintenance and longer service life

Combustion boilers require more stringent periodic overhauls and are subject to combustion wear and residue accumulation.

Aerothermal energy does not generate combustion or waste.
Less corrective maintenance.
Cleaner and more stable operation.

No direct emissions in the home

Unlike gas or oil, aerothermal energy does not produce direct emissions at the point of consumption. This improves the energy certification of the property and reduces the carbon footprint.

Indoor combustion elimination.
Increased safety against leaks or gas evacuation problems.
Natural integration with solar panels for self-consumption.

Greater comfort and control

The aerothermal system works in a modulated way, adapting the power to the real demand. This results in a more stable temperature and fewer thermal peaks.

App control and intelligent programming.
Zoning by rooms.
Cooling in summer with the same system.

In homes in Girona that currently use oil or old boilers, the replacement by aerothermics can mean a significant improvement in efficiency, comfort and stability of energy costs.
