By Julius de Waal

Edgar T Westbury designed his iconic Heinrici hot air engine back in the 60s based on the type of engines used at the start of the century for domestic and light industrial duty including fog horns, ventilation and driving small machines. Until the advent of of the ubiquitous fractional horse power electric motor, these engines plugged away for years, largely unattended. Then even hot air engine toys and models became less popular and largely disappeared. Westbury and other model engineers revived interest in hot air engine models which now have a large, dedicated following. More recently hot air engines started finding industrial use again.

Here, Julius revisits Westbury’s Heinrici design.
