Be the preferred choice of the professional channel through sound processes, engaged people and quality heating solutions delivered with service excellence. At Devex Systems our objective is simple - we grow our business by helping our partners grow theirs. How do we achieve this? By being a reliable supplier and offering training, free design services, same day dispatch as well as after-sales support.

Since 1978, Devex Systems has been advocating the superior comfort of radiant floor heating Australia wide. 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.

Cold storage spaces have their own unique environmental climates and need to be separated from surrounding spaces to avoid condensation and ice formation. While proper insulation and a vapour barrier are essential to minimise heat escaping, they do not fully prevent it. Devex Systems offers heating cables for freezers and coolrooms specifically designed to generate the heat necessary for use in these specific environments.
The ability to regulate either the floor temperature, room temperature, or a combination of both. Devex Systems' Xmat MG-150 electric floor heating mat is only 3.5mm thick and uses a twin conducting heating cable for ease of installation, with very low EMF. It can be easily installed directly over concrete, fibre cement sheet or F-board insulation and into thin adhe- sive beds or floor levelling compounds.
Are you building or renovating? Heating concrete slabs, or in screed floor heating is a great way to heat a kitchen or large living areas (over 60 m)! The heat radiates from the floor giving you a comfortable warmth that won't blow dust around like forced air heaters. Allergy sufferers can breath a sigh of relief!

A great company to deal with. I self installed heating in a small bathroom and large kitchen during renovations with their X-cable product . When I can afford to reno the next bathroom will have no hesitation to order again. Cheryle was extremely knowledgeable over the phone and my kit was sent same day. I had one hiccup with a part but that was quickly rectified without fuss and replacement part sent instantly.The installation was far less complicated than I first thought.
- great service & support
- great product
- local Australian business

We purchased the Comfortline Slimline Ceiling Heating Panels for our children's room and they are amazing! I love the fact they attach to the ceiling away from little hands and one less thing on the floor. The heating takes the edge of the cool nights enough for a good night sleep. Amazing!

Devex was recommended by our builder who only works with great suppliers. The people at Devex were terrific, Susan helped us choose what was right for us and Colin did a very professional installation, he's done thousands I'd say. Good product and a very fair price too. Thanks Devex.
