Amtrol expansion tanks for heating systems

They are used in modern energy-saving heating systems closed. What these systems differ from traditional described in the article "The Evolution of heating systems"

Amtrol Expansion tanks are steel housing with built-in membrane of artificial rubber and are designed to compensate for the expansion of the liquid circulating within the heating system.

Amtrol expansion tanks for heating differ:

*on the maximum allowable working pressure, ie wall thickness of the tank (depending on the operating pressure used type of heating system)
*the type of mounting flange to the tank - removable or fixed membrane (for tanks with small capacity are usually rolled manner of attaching the flange to the tanks of large capacity flange screw, which allows the replacement of membranes)
*the type of rubber - for systems operating on water use heat-resistant rubber SBR, for the systems to use antifreeze membrane of rubber Nitril
*in capacity, which should be specially calculated for each specific system, depending on its internal capacity and power boiler

The design, selection and calculation of the expansion tank for heating

Amtrol expansion tank

Amtrol expansion tank - a product consisting of a metal container containing within the second container in the form of elastic rubber for heating and plumbing supply buildings of varying height.

So far, the function of this apparatus is little known and most consumers are sold without the necessary explanations.
In this text we want to explain the need, and emphasize the importance of its function and why did not need to look for other solutions, leading to unjustified material costs.

The first chapter, we shined on "expansion tanks for heating systems"

Evolution of heating systems.

The old heating system housing using natural circulation of hot water, which is used to support piping of suitable diameter, the large size of which decreases with time, and more and more increasing distance from the boiler to the radiators.
