An indirect Fired Heaters can be understood as a boiler. The energy produced by the combustion of liquid or gas fuels in the boiler, is transferred to a heat-transmitting intermediate fluid – basically water in liquid or gas form or thermal fluids, which is responsible for transporting the energy to other equipment – reactors, exchangers

Fuel flow control. The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding

Direct fired water heaters are solely dedicated to the job of hot water generation, providing a faster heat up and response time compared with an indirect system which is in fact 'heating water to heat water'. This increases the chance of heat losses in the boiler, and associated pipework between the boiler and calorifier.
