Aerothermal: What It Is, How It Works and Its Integration with Zennio

Nov 28, 2025 | News

Aerothermal systems are becoming a key component in energy-efficient buildings. Their ability to extract energy from the air and convert it into heating, cooling or hot water makes them a sustainable solution for homes and businesses. When combined with Zennio’s smart home automation solutions, the potential of aerothermal systems is significantly enhanced.

In this article, we’ll explore what aerothermal energy is, how it works, the benefits it offers, and how Zennio facilitates its integration into KNX-based home automation systems.

What Is Aerothermal Energy?

Aerothermal energy is a renewable energy source that uses heat from the ambient air to generate heating, cooling, and domestic hot water (DHW). It works through heat pump technology, where a device captures outside air, extracts its thermal energy and transfers it indoors.

Aerothermal systems are considered highly efficient because they consume very little electricity. For every kWh of electricity consumed, these systems can produce up to 4 kWh of heat.

Core Components:

  • Outdoor unit (extracts air)
  • Indoor unit (distributes heat or cool air)
  • Thermal storage (for hot water)
  • Controllers or thermostats (for regulation and automation)

How Does Aerothermal Energy Work?

The working principle is based on thermodynamics. The aerothermal heat pump captures the heat present in the outside air, even at low temperatures. This energy is compressed and raised to a higher temperature, then distributed throughout the building.

Modern aerothermal systems can also reverse the cycle, offering cooling during warmer months, similar to an air conditioner.

Benefits of Aerothermal Energy

  • High efficiency: Reduces energy bills due to low consumption.
  • Sustainability: Uses renewable energy from air.
  • Low maintenance: Fewer mechanical parts mean fewer breakdowns.
  • All-in-one solution: Heating, cooling and hot water in one system.
  • Compatible with underfloor heating and fan coils.

Aerothermal technology is particularly suitable for new constructions or energy refurbishments seeking near-zero energy consumption.

Aerothermal and Home Automation: A Perfect Match

The real potential of aerothermal systems unfolds when integrated with smart home systems. Through automation, users can:

  • Adjust temperature based on time, presence or season.
  • Remotely control heating or cooling from mobile devices.
  • Integrate climate control with lighting, blinds or weather sensors.

This level of integration maximises both energy savings and comfort.

Zennio and Aerothermal Integration via KNX

Zennio provides seamless integration of aerothermal systems with KNX, the global standard for smart building control. Thanks to Zennio’s bidirectional gateways, users can centralise control and monitoring of their aerothermal system within their home automation environment.

Zennio offers two specific gateways for aerothermal integration:

  • KLIC-DA v2: Designed for popular Daikin Altherma aerothermal units.
  • KLIC-MITTE: Tailored for Mitsubishi Electric Ecodan systems (IT connector).

These gateways allow:

  • Full communication with the heat pump.
  • Monitoring of temperature, status and alerts.
  • Setting of modes, temperatures and schedules.

Aerothermal and Energy Efficiency Regulations

The installation of aerothermal systems is aligned with the goals of the European Green Deal and national building efficiency codes. In Spain, for example, the Technical Building Code (CTE) promotes the use of renewable systems like aerothermal energy in new residential and commercial projects.

Automation via KNX, together with Zennio integration, helps comply with regulations while adding value to the property.
