The theoreticals involved in the conversation could go on forever, but that still doesn't get me any closer to an answer for my questions. Do boilers lose efficiency over time? Would I see any fuel savings if I switched to a modern boiler? Is my boiler oversized?
Thanks for the help!
: Actually, the post begs the question of whether living in an uninsulated house makes sense at all with today's fuel prices. Insulating houses to modern standards cuts the fuel bill 75% and requires a smaller boiler or the thing runs so little that it is off most of the time in the coldest weather. Considering that my fairly-well insulated house of 1100 sq ft can't use more than 28,000 btuh in the coldest weather, the question of using a 210,000 btuh boiler for a house twice the size of my house borders on ludicrous. A modern-insulated house of 2000 sq ft would use about 50,000 btuh in my area, so moving would be a very intelligent option. Some examination of why living in a 2000 sq ft house and getting a Humvee to go to the store for groceries could be a theoretical pastime. But ssshhhh, don't talk too loud about it or the furnace and boiler salesmen could have a cat fit if people learn they make most heaters too big for modern houses.
