Expansion Tanks | Rite Engineering & Manufacturing

An expansion tank is required on all closed loop heating boiler systems. As a boiler heats the system water, the water will expand in volume. Water cannot be compressed but air can, so an expansion tank uses air (or an inert gas like nitrogen) that acts like a cushion or spring against this force. It is vital that the pressure in the system does not approach the boiler relief valve setting or

Hydronic Heating System Expansion Tank

The height of the open safety vent (OSV) pipe above the hydronic heating system expansion tank can vary depending on the building's dimensions i.e, the distance between the highest and lowest water level points in the heating circuit - but there is a formula for working it out.

Expansion Compression Tanks For Heating & Cooling

This tank is the oldest style design and works well when the air is controlled and kept in the tank, not in the system. The compression tank has been used for many years and works very well in specific systems. Using a plain steel expansion tank makes the system an air control system. The air volume or air cushion above the water level in the

Tankless Water Heaters and Thermal Expansion Tanks

When there is a closed system with a heating source, there is a potential for pressure increases from thermal expansion. This is the case with tankless water heaters installed with a recirculation loop and a storage tank. Therefore, a device, such as a thermal expansion tank, must be provided to control the potential pressure increase. The
