Soundproofing kit for heat pumps


Our SonoKit 1 reduces noise pollution without loss of efficiency. The SonoKit solves this common cause of neighbour conflicts where heat pumps are located close to the neighbour's fence or terrace.


The SonoKit 1 is designed for heat pumps with  vertical fans. The design of the kit guarantees the optimal flux of hot and cold air for best performance of the pump whilst drastically reicing its noise.


Supplied as an easy to install kit. Fits most heat pumps. Our customer has painted his kit in white..

Heat-pump performance guaranteed!

The SonoKit 1 is acoustically efficient but allows good air circulation!


  • The SonoKit 1 is a sound insulation box with two separate compartments:
    • Asipration of the (warm) ambient air through the opening at the top of one of the 2 doors.
    • Exhaust the 'cold' air from the fans through the opening underneath.
  • This mechanism, where hot and cold air are not mixed, guarantees the good efficiency of the CAP.
  • The doors are interchangeable depending on the direction of the side fan.

A simple kit as a solution for a complex problem!

The SonoKit, much cheaper than a legal procedure with your neighbour and an easy and efficient solution. A SonoKit installed around a heat pump that was causing inconvenience between neighbours was the solution that suited both parties.


Initially, the emission measured near the CAP was 70-75dB. By enclosing it in the SonoKit, in front of the air inlet openings the noise level already goes down to 50-55dB ! At a distance of 6m you can hear more than the ambient noise (in our test 43dB on average)....
