Acoustic Heat Pumps coming soon to your homes!

A French company, Equium, has developed an acoustic heat pump that uses the energy of sound to reinvent residential heating. It is powerful, ecological, and easy to use. The EQUIUM Acoustic Heat Pump (AHP) uses the thermo-acoustic effect which corresponds to the propensity of a sound wave to exchange heat with a solid. In their machines, this sound wave of very high power will allow them to pump heat very efficiently and raise its temperature for greater thermal and ecological comfort. The pump is also designed with 100% recyclable materials and has a longevity of more than 30 years. It does not require any maintenance and has a very high efficiency. This technology allows a power modulation, unlike traditional high-temperature heat pumps that must work on/off when the outside temperature is above 5 ° C.

some of the features and benefits of this technology are:


- It uses the energy of sound to pump heat very efficiently and to raise its temperature for greater thermal and ecological comfort.

- It does not use any refrigerants or greenhouse gases, and it is made of 100% recyclable materials.

- It has a longevity of more than 30 years and does not require any maintenance.

- It has a coefficient of performance (COP) of three to four, which means that it produces 3 kW to 4 kW of heat for each kilowatt of power it consumes.

- It can generate domestic water at up to 80°C, which is higher than traditional heat pumps.

- It can work with all external heat sources, including air, water, and geothermal.



Principle of thermoacoustics: a complex natural phenomenon, at the crossroads of 3 disciplines: thermics, acoustics and fluid mechanics.

Acoustic waves are generated and amplified automatically in our machines by temperature gradient or by electricity. They do compression-expansion work in the manner of a piston in a thermal engine or in a compression machine used to produce heat or cold, which makes it possible to carry out ultra-efficient heat pumping, without moving parts and without greenhouse gas refrigerant.
