High efficiency condensing water boiler new design gas condensing water

British Gas - 330 - FREE BOILER MANUALS

2  · A condensing boiler is capable of condensing the water vapor or steam in the otherwise wasted gases in the tubes into liquid water. This phase change process releases additional energy, which is collected and used to further improve the efficiency of the boiler. Figure 3. Vertical firetube boiler. Source: Thermal Solutions

High efficiency condensing boilers | Ideal Boilers

This means that much cooler gases are eventually sent up the flue. Sometimes the flue gases become so cool that water vapour in the gas condenses out - hence the name, condensing boiler! When this happens, even more energy is recovered from the condensing vapour and the efficiency of the heating system gets higher still.

Why Our High Efficiency Condensing Boiler is …

The condensing the part of the water is from the gas fume. There's a lot of moisture in the flue gas. On a regular old-style boiler, they just let the heat exhaust through the stack or chimney, and the exhaust flue temperature can be as high as 150 ° C to 200 ° C or even more, depending on the size of the boiler. In condensing boilers, you're keeping the heat in the boiler longer.
