John Ruck Construction, Leominster, Herefordshire, UK


Green construction from the point of fabrication

John Ruck Construction Ltd manufactures structural steelwork for construction projects. Side by side with the company operates a woodchip production business, Elms Green Woodchip.


Reducing energy costs with sustainable on-site energy production

Since the two companies, John Ruck Construction and Elms Green Woodchip are operating at the same premises, the energy demands of the site is high. The companies’ owner started to search for a way to reduce energy costs. Having interest in renewables, he started to consider CHP systems. Volter 40 Indoor Combined Heat and Power plant was selected because it provided the perfect solution for their electricity and heat demands.


Power of three Volter 40 Indoors providing enough electricity to sell the excess

Three Volter 40 Indoors were installed to cover most of the site’s electricity need. These three independent units are also feeding heat to different buildings within the manufacturing plant. In addition, the heat from the CHP is used for drying woodchip, which added to its drying capacity. Outside working hours, the electricity is exported back to the grid, making the site itself a net exporter of electricity.

Below a time-lapse video of the Volter 40 Indoor installation at John Ruck Construction:

 “The ArborElectroGen45 [Volter 40 Indoor]  units are a great design because they are compact and slick, so they can easily fit into a building. I would definitely recommend them to anyone considering biogas CHP systems.”
John, John Ruck Construction
