## Long description

The Comap Flofix 50 L expansion vessel for domestic hot water is designed for closed hot-water systems to compensate for thermal expansion and stabilise system pressure. With a 50-litre bladder volume and a factory precharge of 4 bar, the vessel helps reduce stress on boilers, hot-water cylinders and pipework. The unit is finished in white and fitted with a 3/4" threaded connection to integrate into domestic heating and hot-water installations.
Advantages
The expansion vessel provides reliable absorption of increased water volume during heating cycles, minimising pressure fluctuations and reducing the frequency of pressure relief valve activation. Its 10 bar maximum allowable pressure rating ensures compatibility with typical domestic installations, while the 4 bar precharge delivers immediate pressure control after installation. The compact 50 L capacity is suitable for many residential hot-water systems, offering a balance between storage volume and space requirements.
Suitable for
Closed domestic hot-water systems
Protection of boilers, hot-water cylinders and piping from thermal expansion
Retrofit or new-build residential heating and hot-water installations
Systems requiring a 3/4" threaded connection
Key specifications
Working fluid: potable hot water in closed systems
Nominal volume: 50 litres
Factory precharge pressure: 4 bar
Maximum allowable pressure: 10 bar
Connection type: 3/4" threaded
External finish: white
How to use
Install the expansion vessel on the return or feed pipe of the domestic hot-water system using the 3/4" threaded connection. Verify the system is depressurised and isolated before connecting. Ensure the vessel precharge matches system requirements; if necessary, adjust the precharge using the valve on the vessel to align with the static system pressure prior to commissioning. After installation, pressurise the system and check for leaks, correct pressure readings and proper bladder operation during heating cycles.
Usage recommendations
For reliable operation, check the vessel precharge periodically and inspect for external damage or leaks. Match the precharge to the static pressure of the installation and allow service access for visual inspection. Where system pressure exceeds the vessel's maximum allowable pressure, select an appropriate alternative. Follow local codes and the heating system manufacturer's guidance during installation and maintenance.
