Our History

With over 80 years ‘experience in the field of thermal engineering, the Simons group has  grown to become a leader in sustainable energy technologies.

Our story began when founder Woolf Simons grew his ice chest-making business into a boiler manufacturing, establishing Simons Boiler Co in 1932 with his sons Asher, Percy and Sol. Soon afterwards, Simons Boiler Co invented the world’s first electric steam iron and assisted Australia’s war effort by pressing uniforms for the Australian armed forces.

From humble beginnings producing small steam boilers and irons, Simons expanded to become a leading provider of commercial steam and hot water heaters.

We continued to build our future. With a vision for a more sustainable Australia, we launched Simons Green Energy in 2011, welcoming an exciting new future as facilitators of clean, reliable and efficient energy solutions serving commercial and industrial markets.

Reliability, sustainability and energy-efficiency from end to end – our defining values have stood behind our successful projects and strong client relationships for over 80 years.

And these values are taking us proudly into the future.
