Lead the charge towards a greener, cooler future, but leave the groundbreaking to the seasoned pros.

The road to becoming the country’s most experienced geothermal exchange design and construct installation company is not an easy one. The journey is marked by a steep and challenging learning curve. Aspiring installers quickly realise that mastering this specialised field requires a unique blend of knowledge, skills, and perseverance.

At the outset, newcomers are faced with the daunting task of understanding the principles of geothermal heating and cooling systems. From grasping the fundamentals of heat transfer and fluid dynamics to delving into the intricacies of geology and thermodynamics, there’s a vast landscape of knowledge to navigate.

No doubt CWL Group’s in-house team of engineers – with unrivalled experience from North America, Europe, and Australia – has been instrumental in this respect.

However, even CWL Group’s engineers are the first to say that a superior design is irrelevant if the installation of said design is not up to the same standards.

Hands-on experience is equally crucial. Novices must hone their skills in trenching, drilling, and pipe fusion techniques. They must become adept at handling specialised equipment such as drilling rigs, heat pumps, and loop installation tools, with CWL Group even having produced a number of their own tools due to suitable alternatives not being locally available.

As a result of these challenges, CWL Group has seen many companies come and go. However, adrift a sea of inexperienced installers promising the earth but lacking the know-how to navigate the complexities of both the design and installation of geothermal exchange systems, CWL Group – with decades of experience and a reputation for excellence – stand out like a lighthouse guiding ships through turbulent waters.

Much of the team at CWL Group have been designing and constructing geothermal exchange systems for nearly two decades. CWL Group has not only more design and construct experience than any other organisation in the country, but likely more than all others combined.

With the experience of over 45 geothermal exchange projects in areas such as government, luxury residential, multi-residential, commercial and aged-care, let CWL Group demonstrate for you how experience makes all the difference down under.

- Jenine Cranston and Douglas Fone, Artarmon, Sydney
We engaged CWL for the geothermal exchange and HVAC works on our unique project in Bellevue Hill and were selected based on pricing and their previous experience. It turned out to be the best choice in subcontractors we made for the whole project. Their professionalism, work ethic, expertise and willing to help wherever needed made a highly complex services installation that much easier, and more efficient than expected. I’d like to personally thank James and the site team who put the extra effort in at all times to get our project over the line with remarkable results. Highly recommended Subcontractors and mechanical consultants.

A culture of striving for excellence combined with motivated and dedicated staff is what defines CWL Group. Their workmanship is second to none and it is obvious that all of the staff care about what they do. Commitments are met and exceeded and there are no problems that can’t be resolved. I’m looking forward to working with Clayton and his team in the future and have no hesitation in recommending them to anyone.

I want to thank CWL Group for the outstanding work in installing our hydronic heating system. I have worked with many plumbers over the years and I have never seen such a high standard of workmanship. They came in on time and on budget. I cannot recommend the team from CWL Group highly enough.
