IBO ITALY 80 central heating expansion vessel – expansion vessel for central heating systems
The IBO ITALY 80 central heating expansion vessel is an 80 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. Inside, a replaceable EPDM diaphragm separates the heating water from the gas cushion.
Who it’s for
-
Heating system installers – the 1" connection and replaceable EPDM diaphragm simplify installation and subsequent servicing 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 pressure in the system.
-
Heating systems operating at higher pressures – a design rated for up to 10 bar and a temperature range of −10 to 100°C are suitable for 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 80 central heating expansion 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 installations, as well as in solar systems operating with heating water or a glycol solution. The IBO ITALY 80 central heating expansion vessel can be installed vertically or horizontally.
Features of the IBO ITALY 80 central heating expansion vessel – description and technical specifications
The vessel body is made of steel coated with protective exterior paint to improve corrosion resistance. A replaceable diaphragm made of EPDM synthetic rubber, resistant to stretching and elevated temperatures, is fitted inside the steel shell. The diaphragm separates the heating fluid from the compressed gas cushion, limiting water contact with the inside of the body.
The vessel is supplied with a factory pre-charge pressure of 1.5 bar ±10%, which can be adjusted to suit the specific installation. It is compatible with closed heating systems with a maximum operating pressure of 10 bar and a fluid temperature range of −10 to 100°C.

Frequently asked questions (FAQ) – IBO ITALY 80 central heating expansion vessel
What is the IBO ITALY 80 central heating expansion vessel used for?
The IBO ITALY 80 central heating expansion vessel absorbs the thermal expansion of water in a sealed central heating system and stabilizes its pressure. This reduces 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 depressurized.
How do I install the IBO ITALY 80 central heating expansion vessel?
The vessel can be installed vertically or horizontally using a 1" connection, usually on the system's return side. An isolation valve is recommended to allow servicing without draining the entire system. Check the pre-charge pressure before start-up.
Where can I buy the IBO ITALY 80 central heating expansion vessel?
The manufacturer does not sell directly. The IBO ITALY 80 central heating vessel is available from sales partners, plumbing wholesalers, and authorized online distributors.
What warranty does the IBO ITALY 80 central heating vessel have?
The IBO ITALY 80 central heating expansion vessel is covered by a 36-month (3-year) manufacturer's warranty. Dambat provides warranty and post-warranty service.
