Discover how Thermor heat pumps with R290 gas offer maximum efficiency, energy savings, and sustainability for domestic hot water production, adapting to any type of home with intelligent and environmentally friendly solutions.
Thermor heat pumps with R290 gas represent a revolution in efficiency, sustainability, and energy savings. Thanks to the use of this natural gas, the Aéromax range achieves exceptional performance and a more environmentally friendly operation.

If you are looking for a smart way to enjoy hot water with minimal electricity consumption, discover the three product ranges that are making a difference: Aéromax VM R290, Aéromax Concept R290, and Aéromax VS R290.

Why choose a heat pump with R290 gas?

The R290 (propane) is a natural refrigerant gas with minimal environmental impact and superior thermal performance. Its low global warming potential (GWP) and high efficiency ensure that every liter of hot water is produced with the lowest possible energy consumption.

Among its most notable advantages:
  • Savings of up to 70% in consumption compared to conventional electric water heaters.
  • Silent and stable operation, even with low outdoor temperatures.
  • Flexible installation, suitable for homes, apartments, and small businesses.
  • Smart connectivity, with remote control via WiFi and automatic efficiency modes.
The result: absolute comfort, real savings, and a clear commitment to sustainability.

An investment that pays for itself

Thermor heat pumps with R290 gas can reduce energy consumption by up to 70% compared to a traditional electric water heater. In addition, by operating with a renewable energy source such as air, they do not depend on fossil fuels nor do they generate direct emissions.

The return on investment is usually achieved within a few years, especially when combined with photovoltaic installations, maximizing self-consumption of electricity.

Installation and maintenance tips

To get the most out of your Thermor heat pump:
  • Install it in a ventilated space with sufficient air intake and exhaust.
  • Make sure the installation is carried out by an authorized professional, especially since it involves a natural refrigerant gas (R290).
  • Clean the air filters regularly and check the proper drainage of the condensate.
  • Use the WiFi app to schedule times, modes, and analyze your consumption.
Proper installation and regular maintenance ensure maximum lifespan and optimal energy performance.

Conclusion: the smart choice for your home's comfort

Thermor heat pumps with natural refrigerant R290 have redefined the standard of efficiency in domestic hot water production. With three ranges adapted to every type of home —VM, Concept, and VS—, Thermor offers a modern, connected, and environmentally friendly solution.
