Look for a silver braided hose connected to lever valves either end...Open one valve then the other to top up your system to between 1 and 1.5bar

By the way I am assuming that you mean the pressure on the heating side has dropped...apologies if not

There's no flow restrictor on the 36 but there may be a filter on the main into the boiler. If so check it's clean.

Have you got a Scale reducer or Water Softener? if not I'll bet the hard Hetrforshire water has scaled up the plate heat exchanger, replacement is the best answer
