When you heat water, disolved oxygen comes out and as the water cools, it re-absorbs CO2. This is what causes the PH to lower. Ph is not your problem. Whether you have a steam or HW boiler, as said 10, isn't bad. That is the level where most metals corrode the least. Litmus paper is subjective though.
