Hello people hope your all well

Need some advice . I had a new boiler installed got a MAIN eco elite combi boiler . I previously had a glowworm boiler.
Issue I have is since the new boiler has been installed the water pressure for hot water has significantly reduced ! With the glow worm boiler the water pressure if anything Was too much .

Any ideas what could be causing this does a tap on the boiler or something need opening more . I have attached a pic

What glow worm did you have? Could be the restriction set by the boiler. Check your stopcock is fully open. All valves underneath appear ok.
 
Unlikely pressure, its prob flow thats restricted. If you can time how long it takes to fill a 4 pint jug with hot and cold (for comparison) then we'll have a much better idea of where your at.

Low hot water pressure in entire house (Heatslave External 25/32)
We have low hot water pressure in the entire house. Boiler is a Heatslave External 25/32, fuel in kerosene. The central heating is still working. Water initially heats up but soon flow ceases. The gauge pressure is correct. Do I need to release air or residue somewhere? Thank you.
