Joule started manufacturing copper vented hot water cylinders when it became common for houses to have a piped hot water system.
Joule became one the of the first to manufacture unvented hot water cylinders. The first version of these cylinders was a copper internal shell rather than stainless steel.
With the increase in demand for hot and cold water storage solutions for flats and apartments Joule launched the market leading combi whisper. The revolutionary tank provided pumped hot water while keeping the noise levels low.
The Cyclone stainless steel unvented cylinder was launched. The new cylinder was a mains pressure hot water cylinder manufactured using durable stainless steel. The Cyclone cylinder is the corner stone of the Joule brand to this day.
Joule launches the new range of solar thermal solutions. With the world looking to reduce energy consumption people needed a solution to heat their hot water cylinders that did not rely on fossil fuel.
Building on the move from supplying hot water cylinders only, Joule launches it new range of underfloor heating. The underfloor heating system is a perfect partner to Joule’s solar and cylinder range.
With the requirements for more efficient heating systems Joule took a major step into the air source heat pump market. Partnering with leading manufacturers. Joule combined its complete product portfolio to offer a complete system solution.
As heating systems became more complex and interconnected Joule opened a design office to offer our customers assistance in their system specification and design.
To compliment the complex interconnected systems the design office were required to specify to meet customers requirements, Joule open its system pre-plumbed department. The range and finish of this product range quickly developed.
The system pre plumbed product range developed into the "Easy Plumb". The new pre plumbed box incorporated stainless steel tubing and all components fitted into a easy to mount box which could be fixed to a wall near the cylinder.
This year saw the launch of the "smart plumb by Joule". This is our most advanced system solution, which incorporates a buffer tank and hot water cylinder in one. Total plumbing required is greatly reduced. Ascetically superior to anything made previously.
The Aero cylinder marked a major advancement in Joule’s product portfolio. The cylinder heats the water using heat pump technology. The cylinder is up to 3 times more efficient and in terms cheaper to run than a conventional electrically heated hot water cylinder.
