Aerotermia in Calvià: what it is and how it works in your home
Aerotermia in Calvià starts from a simple idea: instead of burning a fuel to produce heat, it takes energy from the outside air and moves it into the home. The main equipment is an air-to-water heat pump, an outdoor unit installed on the terrace, in the garden or in a ventilated area, which works together with a hot water tank and the home's emitters.
The cover image shows a white outdoor unit, with an intake grille and fan, resting on a concrete base next to a window. It is a common installation in Mallorca: the unit stays outdoors, protected from the rain and with space for air to move. That same unit can serve both the heating and the domestic hot water.
What it improves compared with an oil boiler
An oil boiler needs a tank, a truck to refill it and a burner that runs periodically. Aerotermia replaces that setup with electric equipment that does not store fuel and does not produce fumes inside the home. These are the improvements a homeowner usually notices:
- No oil tank: the space taken up by the tank and the tasks of filling and checking the level disappear.
- No fumes or smells: there is no combustion inside the home, so no gases or residues are generated indoors.
- More comfort: the heat pump can maintain a stable temperature and work with lower water temperatures than a boiler, which suits underfloor heating or low-temperature radiators well.
- Cooling in summer: depending on the equipment and the emitters, the heat pump can also provide cooling, something an oil boiler cannot do.
- Less fuel-related maintenance: the checks specific to the burner and tank are removed and replaced by the usual maintenance of the aerotermia equipment.
How much can be saved per year: variables to consider
There is no single figure. Annual savings depend on the home, the insulation, the floor area, the price of oil and electricity, and how the heating is used. Even so, in a standard home in Calvià that replaces an oil boiler with aerotermia, the savings usually come from two sources: the lower cost per unit of useful heat and the disappearance of the tasks associated with oil.
To get an idea, it is worth comparing the annual oil consumption with the expected electricity consumption of the equipment. The heat pump does not produce one unit of heat for each unit of electricity; it can provide several, so the cost per thermal kWh is usually lower. The result varies with the flow temperature, the type of emitter and the operating hours. That is why, before deciding, it is advisable to review the home and make a calculation tailored to your case.
Factors that tip the balance
- The insulation of the home and the condition of the windows.
- The type of emitter: underfloor heating, existing radiators or fan coils.
- The setpoint temperature and the hours of use per day.
- The price of oil and electricity at any given time.
- The sizing of the equipment and the location of the outdoor unit.
The installation in a home in Calvià
In Calvià, many homes have a terrace, garden or patio where the outdoor unit can be placed. It is important to choose a spot with sufficient ventilation, resting on a stable base and, if possible, with shade or protection from direct sun, as can be seen in the image. You also need to plan the pipe run to the hot water tank and the emitters, and leave access for maintenance.
Aerotermia is not equipment chosen only by brand or power: the result depends on the load calculation, the type of emitters and the controls. Correct sizing avoids unnecessary starts and allows the equipment to work in its efficient range. If your home already has underfloor heating or low-temperature radiators, the replacement is usually more straightforward; if the radiators are old, it is worth assessing whether they need adapting.
A first step: reviewing your specific case
Before changing the oil boiler for aerotermia, it is worth reviewing the home, the current consumption and the available emitters.
