## Summary description

Reflex DE expansion vessel, 80-liter capacity and 10 bar maximum pressure, designed for domestic hot water (DHW) systems. The diaphragm-type vessel compensates volume changes and pressure fluctuations in closed hot water circuits, protecting pipes and appliances. Suitable for installation in residential or commercial DHW systems requiring an 80 L buffer and 10 bar rating.

## Long description

Reflex DE 80 L expansion vessel for domestic hot water systems is a diaphragm-type pressure vessel designed to compensate for volume changes and pressure fluctuations in closed DHW circuits. With an 80-litre usable volume and a maximum allowable pressure of 10 bar, this expansion vessel helps maintain stable system pressure, reduces stress on pipes and fittings, and supports consistent operation of water heaters, boilers and circulation loops in residential or light commercial installations.
Advantages
The diaphragm design separates the gas and water chambers to prevent waterlogging and ensure reliable pressure response over prolonged service life. Built for a 10 bar maximum working pressure, the vessel provides sufficient margin for many domestic and small commercial hot water systems. Its 80 L capacity offers a buffer for larger DHW volumes, reducing frequency of pump cycling and maintaining steadier temperatures. The compact cylindrical shape and standard connection interface simplify integration into existing installations and maintenance procedures.
Suitable for
 Residential domestic hot water systems with larger storage or high draw-off rates
 Small commercial DHW installations such as offices, guest houses or workshops
 Systems that require compensation for thermal expansion and protection of fittings and valves
 Installations where a diaphragm-type expansion vessel is preferred for long-term pressure stability
Key specifications
 Nominal volume: 80 litres
 Maximum working pressure: 10 bar
 Vessel type: diaphragm (separated gas and water chambers)
 Application: closed domestic hot water (DHW) circuits
 Material and finish: corrosion-resistant steel shell with elastomer diaphragm (standard industry materials)
 Connection: standard threaded connection suitable for DHW installations (check system thread and size before installation)
How to use
Install the expansion vessel on the cold-water side of the domestic hot water loop or at a position recommended by system design, ensuring the vessel is securely mounted and accessible for inspection. Before commissioning, check and set the pre-charge pressure of the gas side to match the system’s static pressure per manufacturer guidance; this ensures correct expansion compensation. Connect piping using compatible fittings, vent the system as required, and verify tightness. Periodic inspection of the pre-charge and for signs of diaphragm failure or corrosion is advised as part of routine maintenance.
Usage recommendations
Verify system requirements such as pipework pressure, water temperature ranges and connection dimensions prior to selection. Match the vessel pre-charge to the system static pressure and perform regular checks of pre-charge pressure and overall vessel condition to maintain reliable operation in domestic hot water systems.
