What is a Heat Exchanger
Boiler Heat Exchangers Explained? A heat exchanger transfers heat from one fluid to another, hence its name. In the case of a boiler, heat is transferred from the gas being burned to the water that will circulate throughout your home. Gas boilers burn gas, which subsequently heats up and rises towards the heat exchanger that the cold water passes through. As the water circulates, the heat is transferred from the gas to the water, which subsequently heats up to heat your radiators or provide hot water for a storage tank. Condensing and non-condensing boiler heat exchangers As mandated in the nation's legislation, all brand-new boiler systems are required to be condensing since they're considerably more energy-efficient than their non-condensing counterparts. This is due to condensing boiler systems having twice as many heat exchangers inside them than their non-constricting counterparts, so they have the capacity to capture and reuse heat from processed gases. Non-condens...
