Understanding water system in new house

white apples

Hoping a plumber could help explain how the water is set up in a house I recently moved into. Our hot water pressure is very bad in the shower and wondering if anything can be done to improve it.

2 storey house, cold water tank in the attic, hot water tank on the ground floor, shower on the first floor. I am trying to understand how the hot water gets from downstairs to upstairs, i.e. flows up. We don't 'have a pump.

From the research I've done it seems like we might have a hot water recirculating system, or gravity loop. Would this prevent the use of a pump? Is there anything that can be done to improve this?

Water will always level out, water going down the pipe is trying to raise back to the level in attic tank. The height of the tank creates 'Head' pressure. So it's Gravity system.

Was your system drained before you moved in, there might be an airlock in the hot pipes. Sometimes this can be cleared by forcing cold mains up the hot pipes, to do this you use your palm to create a seal around a mixed tap outlet e.g your kitchen, then open cold tap and then open hot tap the mains pressure water should force out any air in system.
