Table Comparing Current Home Heating Costs for Oil, Gas, …

When servicing oil heating systems we often found that the efficiency of a dirty, poorly tuned oil boiler or furnace might be as low as 60% or even worse. But thorough cleaning and tuning of the same system would bring older equipment up to aroudn 78% efficient (a 30% reduction in heating costs) and on newer higher efficiency systems we could see efficiencies in the low 90% range.

Fire-tube boiler - Wikipedia

In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion gases. The firebox is surrounded by a cooling jacket of water connected to the long, cylindrical boiler shell. The hot gases are directed along a series of fire tubes, or flues, that penetrate the boiler and heat the water thereby generating saturated ("wet") steam.
