Diffusion turns 50, keeps innovating

By John on March 1st, 2011

Originally named Diffusion Radiator Company, Diffusion started by selling cast iron radiators before moving into designing and manufacturing fan convectors and door curtains predominately for the retail sector during the mid 1960’s. By the early 1970’s Diffusion diversified into designing and manufacturing fan coil units.

Today the company produces an extensive range of heating, ventilating and fan coil units which are sold across a wide range of applications. The Company is believed to be one of the oldest UK manufacturers of this kind of product having supplied the building services market continuously for 50 years.

Diffusion’s Managing Director Leigh Stimpson, who has been with the company for 20 years says:

“We are proud to have been around for this length of time having weathered several recessions, we have always tried to do our best to manufacture quality products that our customers will be satisfied with. Many of our staff have been with the company for many years which gives us stability, while developing new ideas and new products for the future.”
