Boiler circulation systems: natural circulation and forced circulation. For an OTSG system, water travels only one time (single pass) through the boiler tubes before being converted to steam and sent to the steam turbine generator set for producing electricity. On the other hand for steam-drum systems, water has to travel many times (multiple passes) through the tubes before it leaves as steam.

The heater system parts include a heat exchanger on the fireplace itself to heat up water in the pipes. Then water tubes bring the hot water to a radiator. A water pump circulates the water through the system. Then a fan blows heat through ducts in your home. A hot water expansion tank is necessary to prevent the build up of high pressure in the system. Also a water drain valve has been added for maintenance. Also necessary is a pressure relief valve.
