My house has amazing water pressure from the cold tap. It is connected to the mains supply. I live on the second floor. My hot water pressure is not so good. I understand this is because it is a gravity fed system from a tank to the tap so there is no applied pressure.
What I am confused about is where the pressure comes from for the cold?
ETA: I am in the U.K. my hot water system comprises of a tank which is filled via mains water. The tank heats the water over night via an electric heat source. I also have an emersion heater option to heat water up if I use all of the tank in a day. The water is then gravity fed to my taps hence the low water pressure. The tank was fitted in the late 90’s.
My question was: where does the cold pressure come from? not why is my hot water pressure crap.
I couldn’t fathom how without a pump the cold pressure was high despite it having to come UP pipes to my second floor flat and how that remains consistent.
Apologies if I was unclear. 🙂

Every on grid and partial off-grid (well/septic) residential hot water system, in the USA at least, is fed from the mains water supply or well pump into the hot water heater and then to your faucet.
As such, the hot water at your tap should have the same pressure as the cold water unless there is a defect or purposeful restriction in the hot water lines to that tap. I suggest you contact a plumber to see what the issue is.
