If you are considering changing your heating system for a better one, it is very likely that you are wondering how much aerothermal energy would cost in your house, since it provides quite efficient climate control. You may still have natural gas, so you might be interested in this comparison: aerothermal energy or natural gas, which one is better?
In most single family homes or medium sized apartments, the cost of a complete installation usually ranges between 10000 to 16000€ approximately, which can go up to 25000€ depending on the size of the home. This range depends on several factors, such as the chosen heat emission system, the size of the home, the components included or if domestic hot water (DHW) production is also integrated, so we are going to analyze how much it costs to install aerothermal energy in each of these cases.
How much does an aerothermal installation with underfloor heating cost
One of the most efficient combinations is an aerothermal installation with underfloor heating. This system allows taking full advantage of the heat pump performance because it works with lower supply temperatures, which improves energy efficiency.
In general terms the price usually ranges between 14000€ to 16000€ and usually includes:
- Aerothermal heat pump.
- Domestic hot water tank.
- Underfloor heating system.
- Hydraulic installation.
- System commissioning.
Underfloor heating has several important advantages. First, it distributes heat evenly throughout the home, eliminating cold spots and, in addition, improves thermal comfort because heat is emitted from the floor upwards progressively. Of course it can also be used to cool the house in summer, circulating cold water through the circuit.
Although the initial cost is higher than other systems and usually works better when the house is being renovated, the combination of aerothermal and underfloor heating is usually the most efficient option in the long term.
Installation price of aerothermal energy with radiators (low temperature)
Another very common option is to install aerothermal energy with low temperature radiators, which is especially interesting when you want to replace a traditional boiler without performing major works in the home.
The installation price of aerothermal energy with low temperature radiators usually ranges approximately between 11000 to 14000 euros. This system uses radiators designed to work with water at a lower temperature than traditional radiators, while a gas boiler usually works with water at 70 to 80ºC, aerothermal energy usually works between 35 to 55ºC. You might also be interested in this comparison between aerothermal energy and gas boiler.
It is a simpler installation than underfloor heating, which is why it is cheaper while it is also compatible with partial renovations. However, energy performance is usually somewhat lower than with underfloor heating, since aerothermal energy works better the lower the system working temperature is, but even so, it remains a very efficient solution.
How much does it cost to install aerothermal energy with fan coils
Fan coils are another interesting alternative to combine with aerothermal energy. These are indoor units that work through a water exchanger and a fan that distributes the conditioned air throughout the room, and in this case aerothermal energy will cost between 10000 to 13000€. The final price depends on the number of units needed and the complexity of the installation, and its main advantage is that it responds quickly to temperature changes.
In addition, they occupy less space than radiators and can be installed on walls, ceilings or even integrated into false ceilings. In many modern homes, fan coils are used as a hybrid solution that allows enjoying a complete climate control system with aerothermal energy throughout the year.
Factors that influence the aerothermal installation price
Although we have already seen how much it costs to install aerothermal energy, it is something that can vary considerably according to different factors, and these are the ones that will most influence the final budget.
Home surface area
One of the most important factors is the size of the home, since the larger the surface, the more power the heat pump will need and more elements must be installed, which directly affects the system cost.
Domestic hot water (DHW) production
Many aerothermal installations also include domestic hot water production. This requires a storage tank, which can increase the budget between 1000 to 2000 euros, depending on the capacity, which is decided according to the number of people living in the house. However, integrating DHW into the system is usually recommended, since it allows centralizing all thermal production in a single equipment.
Components and equipment quality
The market offers different brands and ranges of aerothermal heat pumps, which at least, if it is an equipment from recognized manufacturers, must have:
- Higher energy efficiency.
- Better durability.
- More advanced control systems.
Subsidies and public aid
Every year there are subsidies for renewable energy installations, including aerothermal energy. These aids can cover between 20% to 50% of the installation cost, depending on the program available to you, in this case, Next Generation funds and all income tax deductions.
For this reason, before performing an installation it is recommended to consult the possible aid available, as they can significantly reduce the final price.
How much does aerothermal energy cost for a 150 m2 house?
In the case of a 150 square meter house, the cost is usually between 10000 to 16000€. In addition to the prices mentioned depending on what you combine aerothermal with, you must take into account the entire surface area to be covered and that, in addition to the climate control system, the budget may also include:
- Domestic hot water production
- Control system and thermostats
- Hydraulic installation
- System commissioning
In well insulated homes, an aerothermal system of this size can cover all heating, cooling and hot water needs.
So is aerothermal energy profitable in the long term?
After seeing how much it costs to install aerothermal energy, we believe that this climate control system is profitable in the long term, standing out for its high energy efficiency. While traditional systems such as gas or oil boilers convert fuel into heat with limited performance, heat pumps can generate up to four times more thermal energy than the electricity they consume, saving quite a lot on all your next bills, up to 70% in fact.
In addition, aerothermal energy has other advantages, such as the reduction of CO2 emissions and that it does not need fossil fuels, without requiring much maintenance and with the possibility of combining it with solar panels. Although the initial investment may seem high, in many cases the system pays for itself before the first 10 years, while its useful life exceeds 20 years, so more and more homes opt for aerothermal energy as their main climate control system.
Thus, if you are wondering how much it costs to install aerothermal energy, you must take into account that the initial price is usually between 10000 to 16000 euros, depending on the installation and the chosen components. In return, you will get an efficient, sustainable system capable of significantly reducing the energy consumption of your home in the long term.
