I'm not a plumber but this layout is like our last house. I suspect the 2 tanks in the loft are 1 for cold water and 1 for central heating - which suggests that you have a vented system, ie not closed pressurised. You mention a 3 port valve - motor control valve - which would supply hot water to central heating only, or to hot water only or to both.
It's possible that your pump is getting noisy because the bearings are starting to go. You didn't say how old it is - if over 10-12 years, this may be the cause ?

The pump needs to be on the lowest setting that gives adequate performance.
Many systems need setting 2 for heating but work fine during the summer for HW only on setting 1.
Few systems every need the pump on setting 3 which is almost always noisy. If 3 is required thats usually as a result of a poor design or system fault or blockage.

If it works on speed one or two then let it be so.

Well said.Agile said:
If it works on 2 then leave it there and tell him how much electricity he will be saving!
Not that much but what does he know.
