The PRV dripping would not affect heating ability.
It probably was dripping due to loss of 'air pocket' at top of tank.
Water expands and pressure increases when heated. The air pocket is there to allow the expansion...air can be compressed----water can't. So when air pocket is lost the pressure will increase enough to cause PRV to drip.

Next time you find it dripping......re-establish the air pocket
Turn off water supply
Open closest faucet (Hot side) to relieve pressure
Open PRV via lever.......when water stops flowing let PRV snap close
Turn on water supply and close faucet.
I really think you have a dip tube that has fallen off.
