Boiler (power generation) - Wikipedia
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boiler Efficiency — What Gross and Net Efficiency Mean
Using the same combustion gas analysers, most high efficiency boilers are about 90% gross efficient (10% of your money is wasted). Changing from a reasonable, old, room-sealed boiler to a new high efficiency boiler will save you about 10% - 15% of the money you spend on gas. Figures claiming savings of 30% or more seem not be be physics but magic.
