What is a FLUE Gas Heat Recovery System ... - Ideal Boilers

FGHRS recover heat from waste flue gases to preheat the cold water entering the boiler lowering the amount of energy needed to warm the water up to the required level. Almost all modern boilers already have some sort of heat recovery built in making condensing boilers much more efficient than older ones. Even so FGHRS can further increase the efficiency of these condensing boilers in most cases

Flue gas heat recovery - Simple Energy Advice

A flue gas heat recovery system uses some of the heat from your boilers flue gases and uses it to help heat your hot water. When your boiler is operating to run your central heating some of the heat it produces is lost through the hot flue gases escaping to the outside air. If you are using hot water at the same time a flue gas heat recovery system can recover some of this heat and use it to pre-heat your
