Description
C.W.U. 19 BASIC diaphragm expansion vessel – expansion vessel for domestic hot water systems
The IBO C.W.U. 19 BASIC diaphragm expansion vessel is a 19 l expansion vessel designed for domestic hot water systems. It absorbs the thermal expansion of water and stabilizes pressure in the system, limiting fluctuations and reducing how often the water heater or pump switches on. It features a replaceable butyl diaphragm designed for contact with domestic water and elevated temperatures.
Who it's for
- Water and domestic hot water system installers – the 3/4" connection, butyl diaphragm, and vertical or horizontal installation make it easier to fit into a domestic hot water system.
- Homes with a water heater or boiler – the vessel absorbs the increase in hot water volume, limiting pressure fluctuations in the system.
- Domestic water pressure systems – the 3.5 bar pre-charge pressure is suitable for systems operating at higher pressures.
- Technical servicing – the replaceable butyl diaphragm, resistant to elevated temperatures, allows the vessel to be restored to working order without replacing the entire unit.
Applications
The C.W.U. 19 BASIC diaphragm expansion vessel absorbs the thermal expansion of water in the domestic hot water system, maintaining stable pressure and limiting fluctuations as water is heated and drawn off.
It is used in domestic and commercial domestic hot water systems, as well as in domestic water pressure systems. The butyl diaphragm is designed for contact with domestic water. The C.W.U. 19 BASIC expansion vessel can be installed vertically or horizontally.
Features of the C.W.U. 19 BASIC expansion vessel – description and technical data
The vessel body is made of steel coated with a protective exterior paint that increases corrosion resistance. A replaceable butyl diaphragm is fitted inside the steel shell, designed for contact with domestic water and resistant to the elevated temperatures of hot water. The diaphragm separates the water from the compressed gas cushion, limiting its contact with the inside of the body.
The vessel is supplied with a factory pre-charge pressure of 3.5 bar ±10%, which can be adjusted to suit the specific installation. It works with domestic hot water systems with a maximum operating pressure of 10 bar.

Frequently asked questions (FAQ) – BASIC 19 domestic hot water expansion vessel
What is the BASIC 19 domestic hot water expansion vessel used for?
The IBO BASIC 19 domestic hot water expansion vessel accommodates the thermal expansion of water in a domestic hot water system and stabilizes the pressure. This reduces pressure fluctuations and how often the water heater or pump in the system switches on.
How does the BASIC domestic hot water expansion vessel differ from the BASIC central heating version?
The BASIC domestic hot water expansion vessel is designed for domestic hot water systems and has a butyl diaphragm suitable for contact with potable water. The BASIC central heating version has an EPDM diaphragm and is intended for closed central heating systems. The two series should not be used interchangeably.
What is the vessel's pre-charge pressure, and can it be changed?
The factory pre-charge pressure is 3.5 bar ±10%. It can be adjusted to match the system pressure by adding or releasing gas through the valve on the vessel connection, with the system isolated and depressurized.
How do I install the BASIC 19 domestic hot water expansion vessel?
The vessel can be installed vertically or horizontally, using a 3/4" connection, in a domestic hot water system. An isolation valve is recommended to allow servicing without draining the entire system, along with checking the pre-charge pressure before start-up.
Where can I buy the BASIC 19 domestic hot water expansion vessel?
The manufacturer does not sell directly. The BASIC 19 domestic hot water expansion vessel is available from commercial partners, plumbing wholesalers and authorized online distributors.
What warranty does the BASIC 19 domestic hot water expansion vessel have?
The IBO BASIC 19 domestic hot water expansion vessel comes with a 24-month (2-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
