ᐅ Heat pumps consume a significant amount of energy and can generate considerable noise.

Hello everyone,
We have been living in our new house for one month now and are experiencing significant noise issues. The noise comes from the manifold of the underfloor heating system as well as the pump itself, which is very loud. The sounds are mostly sharp clicking or ticking noises, especially noticeable in the bedroom. The flow rate and the pump settings have been adjusted, but nothing has improved. However, it is always quiet in the early morning hours. Could it possibly be due to a setting on the unit? The heating technician has already been here but is unsure of the cause. Another technician from Bosch is scheduled to come and take a look, but I’m not sure if the pump is the problem. Also, the house is barely warming up at the current temperatures, and I am using more than 30 kWh daily, which seems very high for a 150 m² (1,615 sq ft) home.

I think I and many others could help better if you answered questions more precisely. In my opinion, it is purely the sound of water, but I cannot completely rule out other causes.

Daniel-Sp19 Jan 2024 22:13Is the noise caused by a single heating circuit? Try checking that.

Eldirwars19 Jan 2024 22:17No, it is not triggered by a single one, but rather intensifies with each individual one.

RotorMotor19 Jan 2024 22:25As the next step, I would try to determine whether the noise occurs only when water is flowing or if the compressor must be running to hear it!

Eldirwars19 Jan 2024 22:32The water only flows when the compressor is running, or am I misunderstanding that? If the compressor is running at a lower capacity, for example only 30 percent, it becomes quieter; when it is running at 100 percent load, it is also louder at the hydraulic mixing valve (HMV).
