A pressurised system on an S plan (two motorised valves. One for HW and one for CH).
Looks rough yes but are all parts required.

Thanks For reply, can this system be replaced with just combi boiler. With no tanks and cylinders.

Looks like upstairs and downstairs are on its own zone plus hw

Should be able to convert to a combi but if your having pressure issues you might have a leak so needs investigation

As above, it looks like 'S' plan with two CH (central heating) and one DHW (domestic hot water) zone.
The motor I think you are referring to is the pump and it is not related to water pressure problems of a domestic nature.
