Stirling technology

The Stirling engine operates on the principle that heated gas expands and cooled gas contracts. A burning flow of fuel and air is used to heat Nitrogen Gas within four cylinders.

The heated nitrogen gas expands in the top hot heat exchanger and is then moved to the lower water-cooled part of the cylinders where it contracts. Cooling water removes heat from the cold cylinder, heat gained via the water can be used for domestic water heating.

The Stirling engine has no valve gear, no air or fuel is taken into or out of the cylinder, this allows the Stirling engine to operate in a very clean and quiet manner. Rapid heating and cooling, expansion and contraction of the nitrogen gas causes pistons within the cylinders to move. The up and down motion is connected to a rotary generator via our unique
‘Wobble Yoke’.
