eleXion provide the UK market with a range of both standard and fully customisable buffer storage vessels, thermal stores, and stored hot water solutions.


Our range covers a variety of applications, including heating, chilled, and stored hot water solutions.

Fully customisable means fully customisable, we can cater to on-site restrictions where access may be an issue, integrate multiple energy sources, and specify pipework locations for both replacement and new projects. With baffles, deflector plates, and other customisations, the possibilities are endless.


We have the capability to produce small, bespoke domestic vessels from 20 litres, up to district heating units exceeding 150,000 litres.

We offer assistance during the design phase to ensure the proposed vessel selection is suitable for its intended purpose.


Each custom project receives a detailed drawing for your sign-off before fabrication begins.


We design, manufacture, and distribute all our products in accordance with the requirements of the ISO 9001:2015|standard (Quality Policy UNE-EN-ISO-9001).
