Air-source heating for cold climates: The best heating system for this climate?

With the wide range of options available, choosing the most efficient and appropriate heating system can be complicated.

In this context, aerothermal energy is one of the most innovative and efficient technologies.

But is it really the best choice for cold climates?

Below, we will explore in detail the performance of aerothermal in cold climates and what factors to consider when choosing the right heating system.

Is Air-source energy the best heating system for cold climates?

Air-source heating is a heating system that uses a heat pump to extract energy from the outside air and transfer it to the inside of the house, generating heat efficiently.

This system is not only efficient, but also more sustainable and environmentally friendly compared to other traditional methods such as gas or oil boilers.

In cold climates, the key question is whether aerothermal can offer the same level of comfort as in more temperate climates.

The answer is yes, but taking into account some nuances.

Modern heat pumps are designed to operate efficiently even at very low temperatures.

Although performance may vary depending on the model and site-specific conditions.

Therefore, for extremely cold climates, it is important to select a heat pump designed specifically for these conditions.

In some cases, it may even be advisable to combine it with a backup system for the coldest days of the year.

Do heat pumps work in the cold?

Heat pumps operate through a process of compression and expansion of a refrigerant, which allows them to extract heat from the air even at sub-zero temperatures.

Los modelos más avanzados, conocidos como bombas de calor de “bajo punto de congelación”, pueden operar de manera eficiente a temperaturas exteriores de hasta -25 °C.

In addition, some aerothermal systems are equipped with technologies such as “steam injection”, which enhances the heat pump’s ability to extract energy in extreme cold conditions.

Therefore, although performance may be affected, heat pumps can still operate effectively in cold climates.

Efficiency of air-source energy in cold climates

It depends on several factors, including the type of heat pump, the insulation of the house and the quality of the installation.

Air-to-water heat pumps, for example, are known for their high energy efficiency, as they can generate more thermal energy than they consume in electricity.

This translates into lower cost compared to other heating systems.

However, the key to maintaining efficiency in cold climates is to select a heat pump suitable for those conditions.

Models with efficient defrost systems and variable speed compressors can better adapt to temperature fluctuations, ensuring optimum performance.

In addition, good home insulation can maximize the efficiency of the aerothermal system, reducing heat loss and improving thermal comfort.

How to choose the right heating system for your location?

Choosing the right heating system for a cold climate involves considering several factors:

• Local climatic conditions: Evaluate the minimum temperature that your location typically reaches during the winter. This will help you determine if you need a low freezing point heat pump or if a standard model will suffice.
• Energy efficiency: models with a higher rating generally offer better performance and lower operating costs.
• Initial cost vs. operating cost: considers both the initial cost of the system and the long-term operating costs.Although aerothermal may have a higher initial cost, its efficiency can result in significant savings on energy bills.
• Professional advice: consult an HVAC specialist who can assess the specific needs of your home and recommend the best solution based on your budget and local climatic conditions.

In conclusion, aerothermal can be an excellent heating option for cold climates, provided that the right model is selected and specific local factors are considered.

With the right choice, it is possible to enjoy a warm, comfortable and energy-efficient home, even in the coldest winters.
