Every school report stated that David liked to talk, so although he left school to become an apprentice plumber back in 1990 and it took a decade, it was no surprise that David entered the world of training and then sales. During his career he has worked for market leading companies such as Worcester Bosch, Yorkshire Copper Tube and laterly, as the specification director at Kingspan Cylinders, before joining Sunamp as national sales manager in 2021. During this time, he has seen the industry adapt to the emergence of first combination and then condensing boilers and sees the use of renewable heat sources in homes, as the next challenge the plumbing industry will face, but with innovative products like the Sunamp heat battery, that challenge is being made a lot easier.
