About
Joule has been built on the foundation of many years of experience within the hot water industry. They started as a small manufacturing company supplying domestic copper hot water cylinders to the Irish market. Having seen over the years what works and what doesn’t the organisation has built an incredible manufacturing system. In 2018 they acquired RM Cylinders bringing together the best of their accumulated knowledge. The result is a class-leading company with an extensive range of quality products and a research and development department bristling with new ideas, bringing innovative products to the market.
