technology

The core innovative technology behind the success of the WhisperGen™ heat and power system is a Stirling external combustion engine.

The four cylinder Stirling WhisperGen™ heat and power system, first released commercially in 1998, produces electricity and hot water suitable for household use or space heating. A patented mechanism, the Wobble Yoke, transfers the vertical motion of the pistons to the rotary motion of the alternator.

The heat to the engine is provided by a burner. Various burners, developed by Whisper Tech Limited specifically for the WhisperGen™ heat and power system, allow different models to operate on specific fuels including diesel, kerosene and natural gas.

off-grid

The 12 or 24V WhisperGen™ heat and power system is used in mobile and other off-grid applications such as boats and small off-grid homes.

You can relax in the knowledge that you have an on-demand supply of power from automatically-charged batteries (directly or through a DC to AC Inverter) to run all those things that make life comfortable. And of course, it does this quietly. It also provides hot water.

It is a better way to make your living environment more like home because it provides a constant and convenient source of electricity and heat, and because it offers a clean burning alternative.
