Sealed System Kits

Sealed (also known as closed) heating and hot water systems are the most popular type of domestic hot water and central heating systems in the UK. Expansion vessels are designed to protect your system from the excessive pressure which accumulates as water heats up. As water temperature increases, the membrane located within the expansion vessel expands, allowing water to enter the vessel and relieving the overall pressure in the system.

Our extensive range of sealed system kits comes from world-leading brands like RWC (Reliance Water Controls), Zilmet and Altecnic, among others. Our kits include everything you need for a straightforward, hassle-free installation, such as wall mounting bracket, filling loop, all necessary valves and so on.

The kits are available with an impressive range of vessel sizes, making them a highly versatile solution, ideal for use across diverse domestic and commercial applications.
