The AIM-traded firm said the project, first announced in February last year, aimed to address the challenge of providing a low-power water heating solution during interruptions to the gas supply, particularly for vulnerable customers such as the elderly or disabled.
During stage one, Haydale said it identified four specific and detailed user case scenarios where their graphene ink-based heaters could be effectively used across Cadent's network.
That initial stage helped lay the foundation for subsequent development work, with building on the findings - stage two of the project - focused on creating an operational pre-product prototype.
The prototype showcased Haydale's functionalised graphene ink, which is printed onto flexible heater sheets.
Those were then enclosed within an insulated 3D printed portable unit.
The board said the prototype had the capacity to heat up to five litres of water when placed on a kitchen draining board or surface.
Power is provided through a rechargeable battery, making the system efficient and sustainable.
“We are looking forward to stage three of the water heater development,” said the company’s UK sales executive, Emerson Whitworth.
“The chance to refine an already fantastically designed product, will give us further scope to add customer friendly features to aid the customer base that Cadent is looking to support with this unit.”
