In Progress

Tamarama Project

Architect: Madeleine Blanchfield Architects

Builder: Bellevarde Constructions

Location: Tamarama, Sydney NSW

System: Geothermal Exchange System with Vertical Ground Heat Exchanger

Capacity: 60kW


Project Brief/Scope: 

  • High-end residential project
  • Variable-speed forced-air heating and cooling
  • Hydronic underfloor heating
  • Pool & domestic water heating
  • Limited space
  • Quiet operation

CWL Group have been engaged to provide an efficient and environmentally-friendly heating and cooling system for an energy-conscious client, successfully navigating such project challenges as:

  • Extremely limited space for fan-coil units and plant due to the contemporary architectural design
  • Various on-site coordination meetings to prepare for the successful installation of the vertical-ground heat exchanger within a space-constrained site
  • Mitigating local council noise concerns of conventional air-cooled systems

The limited site-footprint and council noise constraints made ground-source heating and cooling the obvious choice. However this also presented challenges in terms of executing the necessary drilling for the installation of the vertical ground heat exchanger.

CWL Group drew upon decades of experience to strategically plan the loop installation, which was completed successfully ahead of schedule and paves the way for the rest of the project to be completed with similar levels of success. Upon completion, the Tamarama project will be an impressive blueprint on how ground-source heating and cooling can revolutionise residential properties, regardless of site-impediments that others may deem insurmountable.

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.
