Pump installed in the wrong place also shouldn’t be facing up the bleed screw needs to be on the side or at worst 45 degrees

move next to the boiler ? i left here as it was here before , and it was more convenient for electrician to connect all

After the cylinder but your feed and vent arnt in the best position most likely will pump over

As per my image also best to upgrade to an s plan from a gravity set up also while your at it eg port valves

How is the water pumped through the cylinder coil?

based on that image would be best to put that pump on flow right after vent pipe pumping downwards ?
