About us

Renewable Energy Devices Limited (RED) was incorporated by Dr Jason Cassells, with over 20 years’ experience in the heating and water industries, in March 2014, to bring innovation, highly efficient renewable energy heating products and solutions to the marketplace.  Providing a cost effective and low Carbon alternative to fossil fuelled heating appliances.

RED has developed a market leading range of air source heat pumps along with controls, hot-water distribution and storage systems.  With the correct heating system design and installation, we can provide 5kW of heat for every 1kW of electric consumed, or in other words 500% efficient.

Our heat pump design started with a blank sheet of paper, rather than an evolution of an inferior air-conditioning system and using our skills, knowledge and experience designed a renewable heating solution for both the domestic and commercial sectors of unparalleled performance.  Key objectives were efficiency, performance, noise, aesthetics, ease and simplicity of installation.

Conceived, designed and manufactured in Lurgan, Co. Armagh, to provide simple and efficient heating for your home or business, we are proud of our achievement and hope you will be too.
