Water cannot compress. As soon as the air compresses it takes the load applied by thermal increase and relieves the water pressure from the rest of the plumbing. When water is heated, it expands due to a phenomenon known as thermal expansion. Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering. We offer a range of expansion tanks for potable and non-potable applications. An expansion tank allows for this increased pressure which means it is a vital part of any sealed system. The boiler expansion vessel contains a certain amount of air within it; this absorbs excess water pressure caused by thermal expansion as air can be partially compressed. The air that is present within the tank acts to maintain and provide ... An expansion tank is a small two-gallon vessel with a rubber bladder inside.
