The Universal Expansion Vessel Bracket is a wall-mounting kit for cylindrical expansion vessels up to 24 litres. It provides a secure, off-floor installation for both heating and potable expansion vessels in plant rooms, airing cupboards, and boiler rooms — keeping pipework tidy and the vessel stable at all times. The kit includes a wall-mounting plate, an adjustable securing band (jubilee-style clip) and wall fixings, and is compatible with the wide range of vessel diameters found across the market.

Installation tip: Always mount the expansion vessel with the water connection at the bottom and the air valve at the top (unless the vessel manufacturer specifies otherwise). This orientation ensures the membrane sits correctly, prevents water pooling above the membrane, and makes checking the pre-charge pressure straightforward.
Key Features
Adjustable Securing Band
The adjustable band clamps around the vessel body and tightens to hold it firmly against the wall plate, accommodating a wide range of vessel diameters commonly found on the market. No need for a bracket sized to a specific model — one bracket works across multiple vessel ranges.
Wall Fixings Included
The kit includes wall fixings (screws and rawl plugs), so there is no need to source fasteners separately. The wall plate is pre-drilled with standard fixing centres for rapid installation to masonry, brick, blockwork or timber studwork.
Off-Floor Installation
Wall-hanging the vessel frees up floor space in airing cupboards and plant rooms — a genuine benefit where every centimetre counts. It also reduces the risk of accidental impact or knocking from floor-level activity, and makes the vessel connection easier to inspect and service.
Universal Compatibility
Designed to work with both potable (DHW) and heating expansion vessels up to 24 litres, the bracket is a stock item for engineers carrying out routine replacements, new installations, or cylinder swaps where the existing bracket is absent or damaged.

Frequently Asked Questions
Will this bracket fit any brand of expansion vessel?
The adjustable band makes it compatible with most cylindrical expansion vessels up to 24 litres, regardless of brand. This includes vessels from Joule, Zilmet, Flamco, Reliance, Trade-Tec and most other market brands. Verify the vessel diameter falls within the band's adjustment range before ordering — most vessels in this size class have diameters between 150 mm and 250 mm, which this bracket accommodates.
Can I use this bracket with a 35-litre expansion vessel?
No — this bracket is rated for vessels up to 24 litres. A 35-litre vessel is larger and heavier; using an undersized bracket risks the band or wall plate being unable to safely carry the weight of a full vessel. For 35-litre and larger vessels, use a bracket rated for that capacity.
Does the expansion vessel supplied with a cylinder come with a bracket?
Many cylinder unvented kits (including the Joule Cyclone Plus range) include a mounting bracket in the box with the expansion vessel. However, if the original bracket is lost, damaged, not included, or if the vessel is being relocated or replaced separately, this universal bracket is the right solution. It is also useful on service call-outs where the original bracket is corroded or missing.
What type of wall can the bracket be fixed to?
The supplied fixings suit masonry, brick and blockwork. For timber studwork, use appropriate wood screws directly into the stud. For plasterboard-only surfaces, do not fix directly into the board — always locate a stud or use appropriate cavity wall anchors rated for the combined weight of the bracket and a full vessel (typically 12–25 kg for vessels up to 24 L). If in doubt, consult a qualified installer.
