Unknown. Purchased by Christie's, an auctioneering company set up in London, England. Manufactured by Louis and Ernst Heinrici, German builders of hot air engines. They manufactured three types of hot air engines before 1940.

Function

Hot air engine (also known as Stirling engine). Pressure of air or another gas will increase when heated and decrease when cooled therefore the working gas is alternately heated and cooled so that the build up of pressure results in the movement of a piston. Used to pump water.

Technical

Hot air engines were more efficient than steam engines or gas engines because any source of heat could power them as long as the temperature was high enough. They produced no carbon monoxide and had relatively low levels of nitrogen oxides. The greater the temperature difference between hot and cold reservoirs, the more vigorous and efficient the engine. Co-axial twin fly wheel, 2" bore by 2" stroke, burner and flywheel brake.
