Oil Central Heating - Which?

Pros of oil central heating. Oil is a highly efficient fuel, so you get a good return on every unit of energy. But modern condensing boilers, which use hot flue gases that are wasted in a standard boiler, are now 90% or more efficient. Replacing a standard oil boiler with a highly efficient modern condensing boiler is relatively straightforward.
