 As did his competitor Edward Finden, Heath outsourced work to a substantial group of engravers into the 1830s and 1840s, and employed a production line technique with division of labour.Heath initially commissioned, and the studio produced, the engraved series "Picturesque Views in England and Wales" by J. M. W. Turner, eventually running to 100 watercolours by Turner for a part publishing project from 1827 to 1838.This collection has been considered a central part of Turner's opus, by Andrew Wilton, but in business terms was not a great success in its time.
