Better for you – the Center range has quality at the heart of every product

And the Center Expansion Vessel range is no different, it’s been re-engineered to include a new universal and professional fitment wall bracket as well as a fully WRAS approved potable range that also includes a Shock Arrestor. A quality range and great value.

Better for the environment - leading the industry on sustainability

As part of our commitment to significantly reduce the impact of our products on the environment, we’ve re-engineered our packaging to reduce the level of single-use plastic and make it 100% recyclable. This means less packaging materials going to landfill and cleaner oceans.

In total we’re removing more than one tonne of plastic packaging per annum equivalent to over 183,000 plastic grocery bags, or 28,500 250ml plastic bottles.

Expansion vessels protect closed heating and hot water systems from the effects of fluid expansion and contraction. They are designed to keep the heating system correctly pressurised as water is heated up and cools down again. Typically, combi boilers require expansion vessels as they work in a closed system.

At Wolseley, we’re the trade heating specialists, so you can rely on our comprehensive selection of central heating and boiler expansion vessels to deliver high performance and durability for your customers.

We stock a huge range of expansion vessels, from smaller 4 and 8 litre systems, through to much larger specifications, like 35 and 50 litre vessels.
