Off the top of my head there isn't much involved with maintenance of a hot water system. Every other year, or every year depending on how obsessive you might be, you should have a cleaning done, vacuum out the flew and heat exchanger. Other than that, get yourself a bleeder key, so that you can bleed out the radiators. Sometimes air gets trapped in the radiator and they won't get completely hot. You just bleed off the air until water starts shooting out, do this with the furnace running.
