We rely on our home's heating system every day. But when something goes wrong, it can be costly to put right. With an expansion vessel, you can have peace of mind that when your water heats up, it can withstand the effects of both thermal expansion and water hammer – preventing the system from failing or at worst, coming apart completely.
All the central heating expansion tanks we have for sale online and in our UK branches are made from high-quality materials and designed to withstand the pressures of modern home life. And you'll also find all the accessories you need for wall or floor-mounted tanks, as well as spare expansion vessel sealed system fittings packs.
What expansion vessels do you have for sale?
We stock expansion vessels and accessories from leading brands including Boss™, Zilmet, and Altecnic. From small 4L wall-mounted options to large 105L floor-mounted central heating expansion tanks suitable for commercial properties.
You'll find a huge selection of expansion tanks to suit heating projects of all sizes. Potable expansion vessels from Zilmet are equipped with interchangeable membranes to ensure a long life, while the Boss™ range has a hard-wearing epoxy polyester powder-coated finish.
If you're unsure of the size of central heating expansion tank you require or would like help deciding on whether a wall-mounted or floor-mounted one is more suitable for your property, why not find a branch local to you, where our experts can give you a helping hand.
What to consider before buying central heating expansion tanks?
Before buying your central heating expansion tank, you'll need to consider which size you need. When water is heated, it can expand to between four and nine percent of its original volume. If the expansion vessel is too small, it won't take enough water out of the system to bring the pressure back down.
Whether you decide that a wall-mounted expansion vessel is better for you than a floor-mounted one, it's important that you choose one that matches the specifications of your water heating system exactly.
If you're still unsure what you need to consider before buying, please feel free to contact us and we can help you decide which expansion vessel is the right one for your system.
