What is the safe pressure for a hot-water-heating

The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.

Worcester Bosch Boiler Pressure Problems | Screwfix

2015-1-3·I also noticed a slow drip coming out of the drain valve thanks to it only being hand tight. So, I assumed that the pressure had dropped due to the water leak (albeit small). After tightening the drain valve I re-pressurised the system (when cold) back to 1.5. However, when the boiler is on, the pressure goes up to 3 bar and into the red.
