Buying a Heat Pump but Worried About Noise? Here's How to Choose a Quiet One
When purchasing a heat pump, many people overlook one crucial factor: noise. A noisy unit can be disruptive, especially if installed near bedrooms or quiet living areas. So how do you ensure your new heat pump won’t become an unwanted source of sound?
Simple—start by comparing the decibel (dB) sound ratings of different models. The lower the dB level, the quieter the unit.
Hien 2025: One of the Quietest Heat Pumps on the Market
The Hien 2025 heat pump stands out with a sound pressure level of just 40.5 dB at 1 meter. That’s impressively quiet—comparable to the ambient noise in a library.
But what does 40 dB actually sound like?
Hien’s Nine-Layer Noise Reduction System
Hien heat pumps achieve their ultra-quiet performance through a comprehensive noise control strategy. Here are the nine key noise-reduction features:
-
New vortex fan blades – Designed to optimize airflow and reduce wind noise.
-
Low-resistance grille – Aerodynamically shaped to minimize turbulence.
-
Compressor shock-absorbing pads – Isolate vibrations and reduce structural noise.
-
Fin-type heat exchanger simulation – Optimized vortex design for smoother airflow.
-
Pipe vibration transmission simulation – Reduces resonance and vibration spread.
-
Sound-absorbing cotton and wave-peak foam – Multi-layer materials absorb mid- and high-frequency noise.
-
Variable-speed compressor load control – Adjusts operation to reduce noise under low loads.
-
DC fan load modulation – Runs quietly at low speeds depending on system demand.
-
Energy-saving mode –The heat pump can be set to switch to energy-saving mode, in which the machine operates more quietly.
