IBO ITALY 36 central heating expansion vessel – expansion vessel for central heating systems
The IBO ITALY 36 central heating expansion vessel has a capacity of 36 l and is 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. It contains a replaceable EPDM diaphragm that separates the heating water from the gas cushion.
For whom
-
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 pressure – a design rated for up to 10 bar and a temperature range of −10 to 100°C supports demanding closed systems.
-
Technical service – the replaceable EPDM diaphragm allows the vessel to be restored to working order without replacing the entire unit.
Applications
The IBO ITALY 36 central heating expansion 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 used in domestic and commercial heating systems, as well as in solar systems operating with heating water or a glycol solution. The IBO ITALY 36 central heating expansion vessel can be installed vertically or horizontally.
Features of the IBO ITALY 36 central heating vessel – description and technical data
The vessel body is made of steel coated with an exterior protective paint that increases corrosion resistance. Inside the steel shell is a replaceable diaphragm made of synthetic EPDM rubber, which resists stretching and high temperatures. The diaphragm separates the heating fluid 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 operating pressure of 10 bar and a fluid temperature range of −10 to 100°C.

Frequently asked questions (FAQ) – IBO ITALY 36 central heating expansion vessel
What is the IBO ITALY 36 central heating expansion vessel used for?
The IBO ITALY 36 central heating vessel absorbs the thermal expansion of water in a closed central heating system and stabilizes the pressure. This limits pressure fluctuations that occur when water expands as it heats up.
What is the difference between the IBO ITALY central heating vessel and the C.O. BASIC version?
The IBO ITALY central heating model 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 BASIC central heating model 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 36 central heating diaphragm expansion vessel?
The vessel can be installed vertically or horizontally using the 3/4" connection, most often on the system’s return side. An isolation valve is recommended to allow servicing without draining the entire system, along with checking the pre-charge pressure before startup.
Where can I buy the IBO ITALY 36 central heating diaphragm expansion vessel?
The manufacturer does not sell directly to customers. The IBO ITALY 36 central heating expansion vessel is available from sales partners, plumbing wholesalers, and authorized online distributors.
What is the warranty on the IBO ITALY 36 central heating expansion vessel?
The IBO ITALY 36 central heating diaphragm expansion vessel comes with a 36-month (3-year) manufacturer’s warranty. Warranty and post-warranty service is provided by Dambat.
