A good old
pilot light Janitrol gas furnace from the 50s or 60s with cast iron burners and Dura Tube heat exchanger will be running when all the new induced draft units have burned up ,it can be effectively argued that the older unit is much more efficient and eco friendly in the long run!Its all about the government conspiring with manufacturers to sell more appliances/cars/etc, if they scare people into spending money,the government gets more tax money, and then the homeowner who bought the new junk, will have to buy more in 5 years or so, I do not and never have bought into the who energy efficient thing, a water heater needs only the same controls they have had for the past 75 years, with a pilot you have hot water when the power goes out, and it usualy never gives trouble, the more gizmos added to it, the more trouble it gives, the more you end up spending
