About Us


Create superior comfort through high quality, sustainable heating solutions.


Be the preferred choice of the professional channel through sound processes, engaged people and quality heating solutions delivered with service excellence.


When did it all begin?

Since 1978, Devex Systems has been advocating the superior comfort of radiant floor heating Australia wide. This form of heating was an ideal solution for typical Australian floor surfaces like tile, marble and polished concrete. Although these surfaces were popular to combat the heat of summer, they were uncomfortable once winter settled in.

As the technology for floor heating evolved, the company remained eager to provide Australians with the most up-to-date products. This meant entering into partnerships with European heat specialists, including DEVI in 1993. These partnerships ensured that Devex Systems continued to offer superior products based on performance and reliability.

The founders Vilma and Kevin Weston retired in 2007 and sold the business. John Balass bought the business as he was drawn to the high-quality products, the people and the consistent focus on excellent customer service.


What can we offer you today?

Since then, we have expanded our product range of radiant heating solutions to meet the evolving needs of our customers. These include hydronic underfloor heating, radiator heating, gas and electric overhead heating and solar integration.

As the business grew, so did our partnerships with the professional channels. Today, our cooperation with electricians, plumbers, wholesalers, architects and engineers is essential to our success.

In 2018, we celebrated 40 years of Heating Excellence. This coincided with the launch of our own brand of electric floor heating cables, mats and thermostats as well as our own branded hydronic gas boilers.

The X cable, X mat, X thermostat and X boiler were specifically designed with our Australian customers in mind. Whilst we still source our products from leading European suppliers, we fabricate our cables and mats in Australia. Hence our move away from importing certain products from overseas.

We believe in strong teamwork. Part of our success is our open culture of accepting new ideas and feedback. We also strongly believe in integrity. Integrity means doing the right thing when we say we will do it. These principles are the foundation of how we strive to deliver beyond what our customers expect.

But, don’t take our word for it!
