Reflex 8 Litre 3 Bar Heating Expansion Vessel 3/4 Connection HV8/C

Keep Your Heating System Healthy & Efficient with the Reflex Expansion Vessel

For heating systems experiencing pressure fluctuations or unusual noises, this high-quality Reflex 8 Litre 3 Bar Heating Expansion Vessel is the unsung hero your sealed system needs. It ensures your system runs smoothly and efficiently, protecting it from the daily stresses of heating and cooling.

Protect Your System with the Reflex Expansion Vessel

The Reflex 8L Expansion Vessel is a vital safety net for your heating system, protecting your boiler and pipework. Water expands when heated; without it, pressure build-up can cause leaks or damage boilers (like Andrews or Morco models), but this vessel safely accommodates expansion.

This specific 8 Litre 3 Bar Expansion Vessel expertly handles pressure changes. Its 8-litre capacity and 3-bar rating suit many domestic sealed systems, ensuring compatibility. The 3/4 inch connection allows easy installation. It maintains consistent pressure for heating efficiency, complementing controls from Honeywell or Danfoss.

Reflex offers robust, precision-engineered construction. Its halves and quality non-replaceable diaphragm use a crimped collar (on 8-25L models) for a pressure-tight seal. Finished with durable grey epoxy. The diaphragm handles flow temperatures to 120°C, resists glycol mixtures, and has low gas permeability. It separates water from an air cushion, absorbing expansion. This protects your heating setup, including pumps (Grundfos, Lowara). Reflex vessels are tested per the Pressure Systems Directive for safety. For alternatives, see Altecnic Ltd.

This Reflex model means fewer call-outs and a longer boiler life – a small part playing a big role in home comfort. For other stuart turner or heating needs, like fittings or items by Gledhill or Kingspan, we can help.
