As some of you know, I used to work as a service man for a heating and ac company, maybe it was just how I was trained, but lately I have been reading on line and looking at videos of oil burner service and repair, and all they talk about is how terrible the old furnaces were and how much oil they burned and on and on....its amazing to me to hear how wonderful the new burners are....Trust me, I remember when the so called Flame Retention burners were the latest thing, the old burners were much quieter, and much more reliable, a 1725 rpm motor and pump will last much longer than any of these new units which are 3450 rpm,also, the old 1940s and 50s oil furnaces had all electro mechanical controls, no circuit boards to burn up and cost a fortune,some of the new units do use less oil, but also you must figure, the stuff from the 50s that is still running with all or most all of the original motors, pumps and controls, has been paid for many years...how many years do you expect the new junk to last,you can buy a lot of oil for the price of a new system that you will have to spend mega bucks on in a few years when some of the electronics fail,or the paper thin heat exchanger burns thru and you have to not only replace the furnace but re paint the smoked up house!!!I didn't realize how cheap furnaces had gotten until I serviced the one in this house,it was put in 5 or so years ago and what a noisy flimsy piece of junk, I wish I could find a good Delco or Waterbury somewhere in a warehouse, you can bet I would put it in here!!!!I have the same low opinion of the new heating equipment that I have of all new appliances...JUNK!!!!!
