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 …
A condensate neutralizer is a tank or a vessel, which is installed in line with a condensate drain from a condensing boiler, water heater or furnace (before it enters the sewer). It’s filled with media which raises the pH level of the condensate, making it safe to discharge into the sewage or septic system.

Below is the formula for “true” (compensated) level, and is based on the following parameters: Lt True Level; Lr Raw Level from DP cell; Lb Level of the bottom tap (in this example, a constant set to -18) Lc Level of the condensing pot / top tap (in this example, a constant set to +32)
Although the boiler output size varies, the external dimensions of the heat exchanger remain unchanged. This allows for one single internal boiler layout for several different output sizes. Furthermore, the hydraulic connections are always in the same position, enabling the same pipes to be used in various boiler output sizes.
Mar 23, 2015 · This range defines what the boiler supply temperature is at full fire and what the supply temperature is at no fire. It is commonly referred to as the boiler supply Delta T. This value isn’t to be confused with the system Delta T, which can and should be much greater in a condensing boiler system. A typical boiler supply Delta T is around 12 ...
