CONDENSING HEAT EXCHANGER CONDENSING HEAT EXCHANGER 5 .1 Function The Condensing heat exchanger "A" in Figure 5.1 has the func- tion of transferring heat produced from combustion of the gas and from the flue exhausted gas to the water circulating in it. Figure 5 .1 By reducing the combustion products temperature, the latent heat of the vapour is transferred to the water circuit, allowing an extra gain of useful heat. -
