IBO ITALY 8 central heating diaphragm vessel – expansion vessel for central heating systems
The IBO ITALY 8 central heating diaphragm vessel is an 8 L expansion vessel designed for central heating systems. It absorbs the thermal expansion of water and stabilizes system pressure, limiting fluctuations as the system heats up and cools down. It contains a replaceable EPDM diaphragm that separates the heating water from the gas cushion.
Who it’s for
-
Heating system installers – the 3/4" connection and replaceable EPDM diaphragm make installation and subsequent maintenance easier in a closed central heating system.
-
Homeowners with a boiler or furnace – the vessel absorbs the increase in water volume as it heats up, maintaining stable system pressure.
-
Heating systems operating at higher pressures – a design rated up to 10 bar and a temperature range of −10 to 100°C support demanding closed-loop systems.
-
Technical service – the replaceable EPDM diaphragm lets you restore the vessel’s performance without replacing the entire unit.
Applications
The IBO ITALY 8 central heating diaphragm vessel absorbs the thermal expansion of water in a closed central heating system, maintaining stable pressure and limiting fluctuations caused by the increase in water volume as it heats up.
It is suitable for domestic and commercial heating systems, as well as solar systems operating with heating water or a glycol solution. The IBO ITALY 8 central heating expansion vessel can be installed vertically or horizontally.
IBO ITALY 8 central heating vessel features – description and technical specifications
The vessel body is made of steel with an external protective coating that increases corrosion resistance. A replaceable EPDM synthetic rubber diaphragm, resistant to stretching and elevated temperatures, is fitted inside the steel shell. The diaphragm separates the heating medium from the compressed gas cushion, limiting contact between the water and the inside of the vessel.
The vessel is supplied with a factory pre-charge pressure of 1.5 bar ±10%, which can be adjusted to suit the specific system. It is compatible with closed heating systems with a maximum working pressure of 10 bar and a fluid temperature from −10 to 100°C.

Frequently asked questions (FAQ) – IBO ITALY 8 central heating expansion vessel
What is the IBO ITALY 8 central heating expansion vessel used for?
The IBO ITALY 8 central heating vessel accommodates the thermal expansion of water in a closed central heating system and stabilises the pressure. This helps limit pressure fluctuations caused by water expanding as it heats up.
How does the IBO ITALY central heating vessel differ from the C.O. BASIC version?
The IBO ITALY central heating vessel operates at a higher working pressure (10 bar) and across a wider temperature range (from −10 to 100°C). It can be installed vertically or horizontally and comes with a 36-month warranty. The C.O. BASIC version operates at up to 8 bar and comes with a 24-month warranty. Both have a replaceable EPDM diaphragm.
What is the vessel’s pre-charge pressure, and can it be changed?
The factory pre-charge pressure is 1.5 bar ±10%. It can be adjusted to match the system’s static pressure by adding or releasing gas through the valve on the vessel connection, with the system isolated and depressurised.
How do I install the IBO ITALY 8 central heating expansion vessel?
The vessel can be installed vertically or horizontally, with a 3/4" connection, usually on the return side of the system. An isolation valve is recommended to allow servicing without draining the entire system. Check the pre-charge pressure before starting up.
Where can I buy the IBO ITALY 8 central heating expansion vessel?
The manufacturer does not sell directly. The IBO ITALY 8 central heating vessel is available from retail partners, plumbing wholesalers and authorised online distributors.
What warranty does the IBO ITALY 8 central heating vessel come with?
The IBO ITALY 8 central heating expansion vessel comes with a 36-month (3-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
