Thermira bibloc aerothermal system

Thermira Bibloc Air-to-Water Heat Pump indoor and outdoor unit


The Thermira Bibloc aerothermal system is a system in increasing demand from clients who seek great comfort and maximum energy savings at the same time, while using renewable energy. It is an ideal system to reduce energy consumption, as well as CO2 emissions, all achieved while using a single energy source for all domestic needs (heating, cooling and hot water).

It adapts perfectly to the majority of the different types of home, as it works with underfloor heating, fancoil or conventional radiators.

The Thermira aerothermal system gives excellent performance, even with low outside temperatures of -20ºC. It has become a perfect alternative to other, less efficient and traditional heating systems.


  • Ideal for both renovation projects and new builds.
  • Thermira can function alongside other, traditonal systems already installed in the home.
  • Real savings in energy consumption; up to 75% of free energy.
  • Greater energy efficiency, with lower operating costs and lower CO2 emissions than traditional systems.
