Expansion Vessel for Heating Systems

• Purpose: Exclusively for closed-loop heating systems (e.g., radiators, underfloor heating) where water is not for human consumption.

• Key Features:

  • Durable Materials: Nitrile rubber diaphragm and epoxy-coated steel shell optimised for high-temperature heating water.

  • Higher Temperature Tolerance: Built to withstand frequent heating cycles.

• When to Use: Ideal for boilers, solar thermal systems, or any circuit where water circulates for heating only.

Why It Matters
Using the wrong type of vessel risks:

• Contamination (non-potable materials leaching into drinking water).

• System Failure (heating vessels lack hygiene certifications, while potable vessels may degrade in high-temperature heating loops).
