The Very Best Geothermal Heat Exchangers Down Under

Not all geothermal exchange systems are created equally. CWL Group combines its decades of North American, European and Australian engineering experience, a team of tradesman that have delivered Australia’s largest portfolio of design and construct geothermal exchange projects, and the world’s best materials and products to ensure that every client receives a result that is second to none in terms of quality, performance, efficiency, and dependabilit

Superior Hydronic Underfloor Heating Design & Installation

Hydronic underfloor heating systems have been installed in Australia for over six-decades, yet you wouldn’t know it by looking at the average local installation and comparing it to those within Europe and North America.

CWL Group brings decades of experience in best-practice from the UK and the north-eastern US to Australia. It typically starts with a computer modelled design tailored to the building’s thermal demands, construction properties, floor finishes, and architectural layout. 

REHAU stainless-steel manifolds are strategically located in locations easily accessible in the future for inspection and maintenance, and premium quality REHAU cross-linked polyethylene (PEXa) pipe is installed by the country’s most experienced installers.

Pipework is installed at tighter-than-standard spacing to minimise hot and cool spots in the floor, which further enables the heat pump to operate at a lower, and more efficient, temperature, potentially yielding tens of thousands of dollars in energy savings over the lifetime of the building.

In-House Professional Engineering

All of our solutions are tailored to both the client and project like a bespoke suit. As such, it all begins with our team of engineers understanding the client’s comfort, sustainability, and/or cost/payback preferences, as the client’s wishes will become our ultimate target.

Typically, a thermal model of the building or development is then created using specialised software to determine peak building heating and cooling loads, often on a room-by-room and hour-by-hour basis. Based on the results of this modelling and input from the client, we are able to determine the appropriate project scope.

As the project continues, key parameters of the system will be engineered and important details coordinated with the spatial limitations of the project. 

Whereas many of our competitors will attempt to design a system on-the-fly on site, our more complex systems are fully modelled beforehand in 3D.

This virtual design approach (often called BIM – or Building Information Modelling) maximises energy and space efficiency, minimises clashes with other trades, and ensures a high level of accuracy and product quality that is otherwise unattainable.

Geothermal Exchange Design & Construct

No matter who you are and what you need, we’re here to be your trusted geothermal exchange partner.

 

  • Engineers – Let us assist you with determining the plausibility of utilising the technology on a project, sizing ground heat exchangers, what specific cost-saving and sustainability benefits can be had, and perform life-cycle cost and feasibility/payback analyses for you.
     
  • Architects – Let us demonstrate how little internal plant space geothermal systems require, and how we can completely eliminate all noisy and unsightly outdoor equipment, whilst assisting you with meeting aggressive sustainability targets (Green Star, BASIX, Nabers, etc.). Once engaged for the construction of the system we designed via the use of BIM, let us install a plant more neat, efficient, and impressive than you ever imagined possible.
  • Builders – Let us simplify your work by fully handling the coordination and logistics of installing geothermal exchange systems in a neat, tidy, and painless fashion regardless of the challenges imposed by latent site conditions, and let us do so in such a way that it minimises the impact on the greater project programme.
  • Mechanical Contractors –  Let us assist you in gaining a competitive edge over your conventional competition, being more sustainable, and overcoming challenges inherent with air-source or fossil-fuel equipment. As your trusted geothermal exchange subcontractor, we can design and construct solutions which adapt your traditional offerings to utilise geothermal exchange technology, with little-to-no change in your scope, or knowledge of geothermal exchange required by your team.

Our Trusted Partners

We wanted to drop you a line to say thank you for your expertise and professionalism during our geo journey. Your patience and outstanding knowledge were visible along the way and greatly appreciated. Congratulations in assembling a team who have all been of the same high standard. It has been a pleasure to deal with all of you.
- 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.
- Theo Elphick, Site Manager, Built
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.
- Mick Carroll, Bellevarde Constructions
The team from CWL Group are very reliable, responsive and efficient in their work. They go above and beyond to make sure the job is completed at its highest standard. The knowledge of the guys is exceptional. I would recommend the CWL Group team every time!
- Annemarie Rodrigo, Bellevue Hill House Keeper
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.
- Robert & Roberta Cook, Blue Mountains
