Description
IBO ITALY 8 L DHW expansion vessel with diaphragm – expansion vessel for domestic hot water systems
The IBO ITALY 8 L DHW expansion vessel with diaphragm is an 8 L expansion vessel designed for domestic hot water systems. It accommodates the thermal expansion of water and stabilizes system pressure, reducing fluctuations and how often the water heater or pump switches on. It has a butyl diaphragm designed for contact with domestic water and elevated temperatures.
Who it's for
- Water and D.W.U. system installers – 3/4" connection, butyl diaphragm, and vertical or horizontal installation make it easy to adapt to a domestic hot water system.
- Households with a water heater or boiler – the vessel accommodates the increase in hot water volume, reducing pressure fluctuations in the system.
- Systems operating across a wider temperature range – designed for temperatures from −10 to 100°C, it supports domestic hot water systems operating under various conditions.
- Technical service – the butyl diaphragm's resistance to elevated temperatures reduces maintenance requirements.
Applications
The IBO ITALY DHW 8 diaphragm vessel absorbs the thermal expansion of water in a domestic hot water system, maintaining stable pressure and reducing pressure fluctuations as water is heated and drawn.
It is suitable for domestic and commercial domestic hot water systems, as well as domestic water pressure systems. The butyl diaphragm is designed for contact with domestic water. The IBO ITALY DHW 8 diaphragm vessel can be installed vertically or horizontally.
Features of the IBO ITALY DHW 8 diaphragm vessel – description and technical specifications
The vessel body is made of steel coated with an exterior protective paint to improve corrosion resistance. Inside the steel shell is a butyl diaphragm 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 vessel body.
The vessel is supplied with a factory pre-charge pressure of 3.5 bar ±10%, which can be adjusted to suit the specific system. It is compatible with domestic hot water systems with a maximum operating pressure of 10 bar and a temperature range of −10 to 100°C.

Frequently asked questions (FAQ) – IBO ITALY DHW 8 diaphragm vessel
What is the IBO ITALY DHW 8 diaphragm vessel used for?
The IBO ITALY DHW 8 diaphragm vessel absorbs the thermal expansion of water in a domestic hot water system and stabilizes its pressure. This helps reduce pressure fluctuations and how often the water heater or pump in the system switches on.
How does the IBO ITALY DHW vessel differ from the C.W.U. BASIC version?
The IBO ITALY DHW vessel operates across a wider temperature range (from −10°C) and comes with a 36-month warranty. The C.W.U. BASIC version comes with a 24-month warranty. Both series have a butyl diaphragm and are designed for domestic hot water systems.
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 CWU 8 expansion vessel with diaphragm, IBO ITALY?
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 CWU 8 expansion vessel with diaphragm, IBO ITALY?
The manufacturer does not sell directly. The CWU 8 expansion vessel with diaphragm, IBO ITALY, is available from commercial partners, plumbing and heating wholesalers, and authorized online distributors.
What is the warranty on the CWU 8 expansion vessel with diaphragm, IBO ITALY?
The CWU 8 expansion vessel with diaphragm, IBO ITALY, comes with a 36-month (3-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
