Completed Project

The Farm

Architect: Fergus Scott Architecture
Builder: Join Constructions
System: Integrated Heating System
Capacity: 40kW

Project brief/scope:

  • Hydronic underfloor heating
  • Pool heating
  • Spa heating
  • Potable hot water heating

CWL Group provided an alternative solution to a conventional heating system for an energy-conscious client with site-specific governing factors such as:

  • Mains natural gas not available and difficult site access for LPG delivery
  • Limited power supply due to the rural location
  • Plant and equipment location limitations

A cost-effective, efficient integrated hydronic heating system was designed and installed by CWL Group to overcome various site limitations using European high-efficiency air to water or air source heat pumps, installed in a cascade configuration producing 40kW heating capacity. With the original proposal of using LPG for the heating system, Join Constructions contacted CWL Group to provide an alternative, more energy-efficient approach, resulting in a future proof solution. The air source heat pumps are installed within a subterranean plant room with virtually invisible air registers to commensurate the architectural design of the home. Remote accessible monitoring, diagnosis and operating parameter control of the heat pumps ensures more cost-effective preventive maintenance and ongoing service of the system.

Six years on, and the homeowner is enjoying a comfortable and efficient heating system with year-round pool and spa heating, coupled with the benefits of a recently installed solar PV system further lowering operational costs.

Our Trusted Partners

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.

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.
