The installation of a boiler economizer helps to solve this problem. An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost.

Economiser and Heat Exchanger Boiler Efficiency Devices

Economisers or heat exchangers may be utilised for gas to water, water to air, air to water or air to air applications. The most common application for economiser utilisation is that an element of boiler flue exhaust gases (carefully ensuring they do not drop below 'dew point' within flue stack) can be re-utilised to transfer heat to a coil or element mounted at the boiler back end.
