IBO ITALY 100 central heating diaphragm vessel – expansion vessel for central heating systems
The IBO ITALY 100 central heating diaphragm vessel is a 100 l expansion vessel designed for central heating systems. It accommodates the thermal expansion of water and stabilizes system pressure, limiting fluctuations as the system heats up and cools down. A replaceable EPDM diaphragm inside separates the heating water from the gas cushion.
Who is it for
-
Heating system installers – the 1" connection and replaceable EPDM diaphragm make installation and subsequent servicing easier in a closed central heating system.
-
Homeowners with a boiler or furnace – the vessel accommodates 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 systems.
-
Technical servicing – the replaceable EPDM diaphragm allows the vessel to be restored to working order without replacing the entire unit.
Applications
The IBO ITALY 100 central heating diaphragm vessel accommodates 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 used in domestic and commercial heating systems, as well as solar systems operating with heating water or a glycol solution. The IBO ITALY 100 central heating expansion vessel can be installed vertically or horizontally.
Features of the IBO ITALY 100 central heating vessel – description and technical data
The vessel body is made of steel coated with an external protective lacquer that increases corrosion resistance. A replaceable diaphragm made of EPDM synthetic rubber, resistant to stretching and elevated temperatures, is installed inside the steel shell. The diaphragm separates the heating medium from the compressed gas cushion, limiting water contact with 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 operating pressure of 10 bar and a fluid temperature from −10 to 100°C.

Frequently asked questions (FAQ) – IBO ITALY 100 central heating expansion vessel
What is the IBO ITALY 100 central heating expansion vessel used for?
The IBO ITALY 100 central heating vessel accommodates the thermal expansion of water in a closed central heating system and stabilizes its pressure. This helps limit pressure fluctuations that occur as water expands when heated.
How does the IBO ITALY central heating vessel differ from the C.O. BASIC version?
The IBO ITALY central heating vessel has a higher operating pressure (10 bar) and a wider temperature range (from −10 to 100°C), can be installed vertically or horizontally, and comes with a 36-month warranty. The C.O. BASIC version operates 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 depressurized.
How do I install the IBO ITALY 100 central heating expansion vessel?
The vessel can be installed vertically or horizontally, with a 1" connection, most often on the system return side. 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 IBO ITALY 100 central heating expansion vessel?
The manufacturer does not sell directly. The IBO ITALY 100 central heating vessel is available from trade partners, plumbing and heating wholesalers, and authorized online distributors.
What is the warranty on the IBO ITALY 100 central heating vessel?
The IBO ITALY 100 central heating expansion vessel comes with a 36-month (3-year) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
