## Summary description

Reflex expansion tank DE 12L (model 7302013) is designed for domestic hot water installations.

## Long description

Reflex DE 12L expansion tank (model 7302013) is designed for domestic hot water installations in closed circuits. The 12-litre vessel accommodates changes in water volume and absorbs pressure fluctuations that occur during heating and hot water use. Its diaphragm design separates the water chamber from the pre-charged gas chamber, helping to stabilise pressure, reduce stress on piping and valves, and protect the boiler and other system components from overpressure.
Advantages
The Reflex DE 12L provides reliable pressure compensation in household hot water systems, reducing water hammer and frequent cycling of pumps and boilers. The compact 12-litre capacity is appropriate for many domestic installations, offering space-saving installation and straightforward integration into existing pipelines. The diaphragm separation reduces contact between water and the gas chamber, which limits corrosion and prolongs functional life of the tank and connected components.
Suitable for
 Closed domestic hot water systems
 Residential boiler installations
 Systems that require mitigation of pressure spikes and water hammer
 Retrofit and service replacement in household plumbing circuits
Key specifications
 Nominal volume: 12 litres
 Type: diaphragm expansion vessel for domestic hot water
 Application: closed hot water circuits in residential installations

How to use
Install the Reflex DE 12L expansion tank on the cold-water inlet or at a recommended point in the closed domestic hot water circuit following national plumbing regulations and the system manufacturer’s instructions. Ensure the pre-charge pressure of the gas chamber matches the system’s static pressure before commissioning. After mounting and connection, perform a pressure test and check for leaks. Routine inspection of pre-charge pressure and visual condition is advised as part of scheduled maintenance.
Usage recommendations
Confirm compatibility with the system pressure range and ensure correct pre-charge setting prior to operation. Use qualified personnel for installation and maintenance to ensure safe, code-compliant fitting and to extend the service life of the hot water installation.
