2L Pressure Vessel for Water Heaters

Description

2L Pressure Vessel for Small Water Heaters

A 2L pressure vessel helps manage pressure changes in a small water-heating installation supplied by a pump. Water expands as it heats. In a pumped or closed system, this expansion can increase pressure. A correctly selected and installed vessel provides space for that expansion and helps protect the water-heating system from unnecessary pressure stress.

Suitable Water Heater Sizes

This pressure vessel is intended for water heaters with a maximum capacity of 20 litres. It is compatible with Atlantic 10L and 15L water heaters, making it suitable for compact kitchen, sink and small hot-water installations.

Correct vessel sizing also depends on the system pressure and installation conditions. Therefore, the vessel and its pressure setting should be checked by a qualified installer.

Pressure Vessel or Expansion Vessel?

This component may also be described as an expansion vessel. Both terms are commonly used when discussing equipment that helps accommodate water expansion and manage pressure changes in a pumped water-heating system.

Need a Larger Pressure Vessel?

Installation Guidance

A pressure vessel should be installed and checked by a competent plumber or technician. Before installation, confirm that that the 2L capacity, 3.5 bar preset charge and 1/2-inch connection are suitable for the water heater, pump and system pressure. The vessel should remain remain accessible for inspection and maintenance. After installation, the system should be checked for leaks and correct operation.
