Rev Hugh Fowler

Prepared by Michael Steer

Thomas Fowler (born 1777 at Great Torrington - died March 31, 1843) was an inventor of the thermosiphon that forms the basis of most modern central heating systems. Fowler patented it in 1828. It was the first convective heating system. A system based on his design was installed at Bicton, part of the Rolle Estate and received acclaim in the Gardener's Magazine of 1829. Due to innate flaws in the patent system of the time, the thermosiphon was pirated by other manufacturers and Fowler did not have sufficient funds to conduct legal proceedings. In 1840 he produced a mechanical calculating machine that operated using balanced ternary arithmetic.
