Aerothermics with underfloor heating: The perfect combination for efficient heating

In a world where energy efficiency and sustainability are priorities, choosing the right heating system is essential.

Aerothermal and underfloor heating have positioned themselves as one of the most efficient and ecological combinations for heating your home.

They offer you comfort, energy savings and a lower carbon footprint.

What is aerothermal energy and how does it work in heating systems?

Aerothermal energy uses energy from the outside air to generate heating, cooling and domestic hot water.

This system, based on a heat pump, extracts heat from the air even at low temperatures, taking advantage of a free renewable resource.

It works through a thermodynamic cycle that consumes electricity, but its efficiency is remarkably high: for every kWh consumed, it can generate up to 4 kWh of thermal energy.

Aerothermal energy not only stands out for its performance, but also for its environmental friendliness, as it emits less CO₂ compared to traditional systems.

How does underfloor heating work?

Underfloor heating is a heating system that uses a network of pipes or electrical cables installed under the floor to distribute heat evenly.

Aerothermal heating complements this system perfectly, as it generates water at a low temperature (between 30-50 °C), which is ideal for the operation of underfloor heating.

The process is simple:

1. The aerothermal heat pump heats the water.

2. This water circulates through the underfloor heating pipes.
3. The heat is distributed evenly, providing a feeling of comfort without cold spots or excessive heat.

The combination of aerothermal and underfloor heating maximises efficiency, as both systems work best at moderate temperatures.

Comparison: Which is better, aerothermal or underfloor heating?

• Aerothermal alone: can be used with radiators, but loses efficiency if heating temperatures are high.

• Underfloor heating on its own: it needs an efficient heat source to make full use of its potential.

Separately, both are efficient systems, but combined they achieve superior performance.

As the aerothermal system supplies water at a low temperature and the underfloor heating distributes this heat evenly.

Advantages of the combination of fan heat and underfloor heating

1. Energy efficiency: reduction of electricity consumption by up to 70% compared to traditional systems.

2. Superior comfort: uniform heat throughout the home and a feeling of well-being.

3. Sustainability: use of renewable energy and lower CO₂ emissions.

4. Economic savings: lower energy bills in the long term.

5. Versatility: can also be used for summer cooling (radiant cooling).

How much does it cost to install underfloor heating?

The cost of installation can vary depending on factors such as the size of the house, the complexity of the project and the geographical location.

However, a complete installation is typically between 10,000 and 20,000 euros.

Although the initial investment may seem high, it is important to consider the long-term energy savings and the incentives or subsidies available in many regions for renewable energy.

How much does underfloor heating consume?

The consumption of an aerothermal system depends on several factors, such as the size of the home, the level of thermal insulation and the outside temperature.

On average, a well-insulated 100 m² house can have an annual electricity consumption of approximately 1,000 to 2,000 kWh.

Installation process of aerothermal heating with underfloor heating

The whole process can take between 2 and 4 weeks, depending on the complexity of the project.

It consists of a series of steps to ensure an efficient installation:

1. Preliminary study: analysis of the energy needs and characteristics of the home.

2. Installation of underfloor heating: laying of pipes or electrical cables under the floor.

3. Installation of the heat pump: location and connection of the aerothermal system.

4. Testing and commissioning: checking the operation of the system.

Is the combination of fan heat and underfloor heating suitable for all households?

This combination is ideal for new homes, where it can be integrated with the initial design and in home renovations with a heating and flooring renovation system.

However, in older homes without good insulation, additional investment may be required to improve thermal efficiency and maximise performance.

Conclusion: Aerothermal and underfloor heating, an efficient and sustainable investment for the home

The combination of aerothermal and underfloor heating not only improves comfort and reduces energy consumption, but also contributes to a more sustainable future.

Although the initial investment may be high, the economic and environmental benefits make it one of the best options for those looking to modernise their home with green and efficient technology.
