Efficient climate control: which systems help you save electricity in winter

Today, technology offers alternatives that let you enjoy a comfortable indoor temperature without your electricity bill skyrocketing, thanks to efficient climate control solutions.

Energy efficiency isn’t just about saving money —it also means reducing emissions and moving toward a more sustainable model. That’s why choosing the right climate control system is key to achieving a more comfortable and environmentally friendly winter.

Below, we explain which systems are most recommended for saving electricity in winter and how they can help improve comfort in your home.

Reversible air-conditioning heat pumps

Although air conditioning is often thought of as a summer-only solution, models with heat pump technology have become one of the most efficient options for winter. These systems extract energy from the outdoor air and convert it into heat for your home, delivering much higher performance than conventional electric systems.

Advantages: they stand out for their high efficiency, how quickly they reach the desired temperature and their ability to dehumidify damp environments. This way, they improve overall indoor comfort.

Savings: by harnessing renewable energy from the surrounding air, they consume far less electricity than traditional electric radiators. This results in a lower bill and more responsible use of energy resources.

Aerothermal systems

Aerothermal energy has established itself as one of the most comprehensive and sustainable solutions for both space heating and domestic hot water production. This system captures energy from the outdoor air and converts it into heat, which is then distributed through low-temperature radiators, underfloor heating or fan coils.

Advantages: it delivers performance far superior to traditional boilers, helps reduce emissions and can be combined with solar energy to maximise efficiency.

Savings: for every kWh of electricity consumed, aerothermal systems can generate up to 4 kWh of heat. This translates into significant savings on your electricity bill and more responsible use of energy resources.

Low-consumption radiators

Next-generation electric radiators have made major efficiency gains thanks to built-in storage systems and digital controls. While they don’t reach the performance levels of aerothermal systems or heat pumps, they remain a practical option for small spaces or homes used occasionally.

Advantages: their main appeal is ease of installation, as they require no construction work or complex maintenance. They are plug-and-play devices, making them a quick and simple solution for those seeking immediate results.

Savings: the most modern models include programmable timers and thermostats that adjust consumption to real-time needs. This prevents unnecessary usage and optimises energy consumption, contributing to a more economical and responsible approach.

Underfloor heating

Underfloor heating is one of the most comfortable and efficient climate control systems, especially when combined with aerothermal energy. It works by distributing heat evenly from the floor upward, eliminating drafts and maintaining a stable temperature throughout the home.

Advantages: it provides superior thermal comfort, as heat is evenly distributed in every room. Moreover, it also stands out for its high energy efficiency.

Savings: as it operates with low-temperature water, underfloor heating significantly reduces electricity consumption compared to traditional radiators, making it a sustainable and cost-effective winter option.

Tips to maximise savings

Beyond choosing the most efficient climate control system, real savings come from responsible energy use. Small actions and good habits can make a big difference to both your bill and your environmental impact:

• Regular maintenance: clean, well-maintained equipment performs better and uses less electricity.
• Home insulation: double-glazed windows and proper sealing prevent heat loss and help maintain a stable indoor temperature.
• Smart use: programming climate control to operate only when needed and keeping temperatures moderate (19–21 °C) is key to balancing comfort and efficiency.
• Combining with renewable energy: integrating photovoltaic or solar thermal panels can complement your heating system and further reduce energy costs.

Efficient climate control: an investment in a sustainable future

Efficient climate control is not just about saving money. Choosing systems such as aerothermal energy or heat pumps reduces dependence on fossil fuels and lowers CO₂ emissions. These technologies are also aligned with European energy transition policies and decarbonisation goals.

Choosing a winter climate control system should strike a balance between efficiency, comfort and sustainability. While electric radiators may be useful in specific situations, heat pumps and aerothermal systems represent the future of residential climate control. Investing in these technologies means enjoying a warm home, lowering your electricity bill and contributing to a cleaner planet.

Ultimately, efficient climate control is an investment in long-term comfort, savings and well-being.
