As long as you don't have a leak that would bring in more dirty water and oxygen, then little more has to be done. The killer of boilers is a leak that is constantly filled by an open hand valve to the pressure reducing valve that makes up water as it is lost. That is why the pressure reducing valve manufacturer says to close the hand valve to the pressure reducing valve and install a low water cutoff instead. That way, the pressure of the sytem drops due to a leak and begins to get noisy from the air, so the leak is fixed instead of slowly killing the boiler.
