Potable

A potable expansion vessel is an essential safety component in a water system. Our Eres potable vessels are designed to be incorporated into pressurised heating and hot water systems for efficient operation and peace of mind. We stock a wide range of Eres vessels that are compatible with most systems. Manufactured by Altecnic, these quality hydronic solutions are practical and affordable.

Our Eres range is suitable for use with potable water, which is water for drinking. These specialised components are designed to handle water expansion, preventing the system from becoming overpressurised. When heated, water can expand by up to 4% in volume. Eres expansion vessels absorb the extra volume, maintaining the system at the correct pressure and ensuring system longevity. Expansion vessels have multiple benefits for any potable water system. Maintaining consistent water pressure reduces the risk of damage to pipework, fixtures, and appliances. As a result, you'll increase the lifespan of the system, saving time and money in the long term.

Eres expansion vessels are available in sizes from 8 l to 24 l to suit most applications. To size your potable vessel, you need to calculate the water volume in the system and the potential for expansion. Our expert team will answer any queries if you're unsure of the correct vessel size for the installation.
