MODULE 70 boiler EFFICIENCY
Foaming inside the boiler tank occurs when solids in the water float to the top. When the water heats, these solids foam from the steam. Some rise through the steam to the turbines or superheaters. When the solids deposit on these, the system loses efficiency. Eventually, the solids will work their way throughout the rest of the boiler, causing

Boilers can suffer from many problems, most of which should be resolved by a qualified boiler engineer. Boiler leaks should be treated as a serious issue and resolved as soon as possible. A lack of central heating could mean that the radiators need bleeding. Low boiler pressure can be caused by leaks and can be solved by opening the filling loop.

In central heating in the UK and Europe, boiler pressure or central heating system pressure is usually measured in bar. One bar is 14.5 psi (pounds per square inch). For years, central heating systems were "open vented," with a feed and expansion tank (known as an F&E tank or a header tank), usually in the loft.

Jun 25, 2014 · Since a condensate pump has an atmospheric vent, you have to use a check valve to keep the water in the boiler from flowing backwards into the receiver tank. The check valve goes in the pump's discharge line. Unfortunately, sludge will often build up in the return line and clog the check valve, keeping it from closing tightly.
