The home I recently purchased has a 2 year old oil furnace that is
hooked into the original 1940's radiator heating system. Everything has
worked fine so far this winter, but I have never owned a
hot-water/radiator heating system before. What is generally recommended
as to maintenance on my part, if anything? Do I just need to have
someone from the oil company clean the burner each year, or does a
water-based system require additional upkeep and maintenance? Do I drain
the pipes in the summer? I'm completely clueless....
