The process by which condensing water heaters make water hot is rather complex. A fan drives air and fuel into a combustion chamber. Here, exhaust gas from the chamber is forced into a heat exchanger inside a water tank. This causes the water in the tank to get hot. It's a truly brilliant design because it's incredibly efficient.

Non-condensing hot water boilers are the traditional commercial facility default option. These boilers do not allow combustion gases to condense in the heat exchanger, which is typically cast iron. They require a return water temperature of around 140ºF to ensure no condensation forms and that there is no thermal shock to the boiler.

The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.
