One of the most frequent doubts is whether aerothermal energy works equally well in cold or mountain areas. The answer is yes: current systems are designed to maintain high performance even in sub-zero temperatures. The important thing is to choose the right equipment and apply certain improvements to ensure energy efficiency in winter.
Do you want to reduce your energy bill by up to 70%? Enter our Aerothermal Guide and find out how it works, how much it costs and what grants you can take advantage of.
Actual performance of aerothermal energy in cold climates
- COP (Coefficient of Performance): most modern equipment maintains a COP of 3-5 even at -7 ºC, which means that for every kWh of electricity consumed they produce between 3 and 5 kWh of heat.
- Savings compared to boilers: according to different studies, bill savings can reach between 50% and 75% compared to gas or traditional electric systems, even in cold climates.
- State-of-the-art technology: brands such as Daikin Altherma or Mitsubishi Ecodan have developed heat pumps specially designed to operate in environments with high thermal demands, such as the Pyrenees or the interior of Castile.
How to optimize aerothermal energy in winter
In order for the aerothermal system to perform at its best in cold climates, it is important to take into account:
- Choose robust and high efficiency equipment, prepared for low temperatures.
- Improve the thermal insulation of the house and have a buffer tank, which helps to stabilize the temperature and optimize the heat pump cycles.
- Combine with photovoltaic solar panels or hybrid systems, which reinforce energy independence and further reduce costs.
- Suitable emitters: underfloor heating and low temperature radiators are more efficient than conventional radiators in cold environments.
Case studies: performance in cold areas
In homes located in mountain areas, such as inland Girona or the Pyrenees, aerothermal heating has proven to maintain stable temperatures throughout the winter. Thanks to good system sizing and integration with renewable energies, users enjoy comfortable heating and reduced heating bills, even when outside temperatures are below freezing.
