## Summary description

Reflex DE 8L 7301013 is an expansion vessel designed for domestic hot water systems with an 8-litre capacity. It compensates for thermal expansion, reduces pressure fluctuations and protects plumbing and water heaters from overpressure. Suitable for residential DHW installations where a compact expansion vessel is required for maintaining system safety and extending equipment life.

## Long description

Reflex DE 8L 7301013 is an expansion vessel for domestic hot water systems with an 8-litre capacity. It is designed to absorb thermal expansion in closed potable water circuits, reducing pressure peaks and protecting water heaters, valves and pipework from excessive pressure. The compact cylindrical vessel is intended for residential DHW installations where space is limited and system pressure stability is required.
Advantages
The expansion vessel provides reliable pressure compensation and helps prevent frequent activation of pressure relief valves. It reduces stress on joints and fittings, lowers the risk of leaks and extends the service life of boilers and hot-water appliances. Its compact size enables installation in small utility rooms or near the water heater, while the pre-charged bladder design ensures consistent performance and fast response to temperature-induced volume changes.
Suitable for
Domestic hot water (DHW) systems in single-family homes and apartments
Compact installations with limited installation space
Protection of water heaters, boilers and circulation systems from overpressure
Systems requiring reduction of pressure fluctuations and drip valve activations
Key specifications
Nominal capacity: 8 litres
Application: closed domestic hot water systems
Function: compensates thermal expansion and stabilises system pressure
Design: compact cylindrical vessel with internal flexible bladder
Mounting: wall or bracket mounting compatible with typical residential installations
How to use
Install the expansion vessel on the cold-water side of the domestic hot water system or as recommended by the heating engineer, ensuring correct orientation and secure mounting. Before commissioning, check and adjust the pre-charge pressure of the vessel to match the static system pressure using a pressure gauge. Connect using appropriate fittings and isolation valves so the vessel can be removed or serviced without draining the entire system. After installation, bleed air from the system and verify that pressure relief devices operate within specified limits.
Usage recommendations
Regularly inspect the vessel for visible damage or corrosion and re-check the pre-charge pressure at least annually or during scheduled maintenance. Replace the vessel if the bladder shows signs of failure, persistent pressure loss occurs, or if maintenance reveals leaks. Use compatible fittings and follow local plumbing and water safety regulations during installation.
