Protect your hot water system with the Ariston Kit A 2 Litre Expansion Vessel and Non-Return Valve, a practical accessory designed to support the safe and efficient operation of unvented water heaters. The 2-litre expansion vessel accommodates the increased volume of water as it heats, helping to prevent excessive pressure build-up and protect the system's components from unnecessary strain.
Supplied with a non-return valve, this installation kit also prevents heated water from flowing back into the cold-water mains, maintaining a safe and controlled water supply. It provides a dependable solution for installations where additional expansion capacity is required. Combining two essential components in one convenient kit, it's an ideal choice for maintaining reliable hot water system performance.
