Question about Heating & Cooling
Does it make noise in both modes, heater and hot water?
Is it the same at all heat settings?
Your problem may be due to hydro water flow switch.
Try putting 2 pieces of plastic pipes in the cold and hot feed pipes to reduce the transmission of the noise.
Also make sure your not putting more than 9 liters a min through the boiler.
You may need to reduce water pressure.
If it is the heater function that is noisy, there may be something clogging the system, and it should be cleaned and back flushed.
Your water supply system may also need an air compression tank to reduce water hammer effects. Water has momentum and it is hard to stop flow quickly without a compressible chamber to absorb the kinetic energy.
Tell me more and I may be able to give a better answer.
