Conserve Oil condensing boiler

Some oil condensing boilers can have an efficiency rating of as much as 91% which is 25% more efficient than a standard non-condensing boiler so switching to one could save you a considerable amount of money.

An oil condensing boiler uses the waste heat gases from heating your water to preheat the water entering the boiler so there is less of a difference in temperature to get the water to the right heat. This makes the whole system much more efficient as you will  not need to use as much fuel.
