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.

KingJulien18 Jan 2024 12:34Your heat pump doesn’t know what settings your ERR has, and it doesn’t really matter to it.
These are just ON/OFF valves, they can’t do more than that.
And the 30 degrees (or any other temperature setting) is basically meaningless.
Trust me, the noises come from throttling. Wind whistles through a keyhole, not an open door.
I would fully open everything and even do a balancing adjustment yourself. It’s not rocket science.

KingJulien18 Jan 2024 12:50There could also be a restriction under the valve caps.
Your heating system should have a minimum flow rate and a flow indicator for the underfloor heating manifold. At least it should.
Try looking for both.

Try looking for both.Where can I find that and where exactly is it under the valve caps? (sorry for my lack of knowledge)
