Yes quieter and more efficient. I advise an Ebara one for price and value.
Also make sure it’s the correct size for your heating system…nothings been added, also check if you have an air leak in the system or the seals are okay as they can perish and do weird stuff that causes cavitation in these Grundfos units that make the noise. I’ve also seen these units just never ever ever seal and generally be a twat.
My grammar is horrific but I deal with these pumps at least 3 times a month in bio plants.

Another question - this pump is for the hot water. It's pretty noisy except on the lowest setting when it doesn't really get the radiators warm.
It's not that old but would a new one be quieter? Or, could it be boxed in safely?
