Project Scope: Design and installation of a cutting-edge, energy-efficient mechanical system for a luxury residential development in Mosman, featuring geothermal heating, underfloor heating, VRF climate control, and high-capacity DHW storage.

Key Project Highlights

Geothermal Heating via Vertical Ground Heat Exchanger
- 10 x 120m deep geothermal probes installed, providing sustainable and highly efficient ground-source heat exchange.
- Significantly reduces reliance on traditional energy sources, lowering operational costs and carbon footprint.
Radiant Underfloor Heating (RDZ UFH) Throughout
- A high-performance underfloor heating system ensures even, comfortable warmth across all living spaces.
- Energy-efficient low-temperature operation complements the geothermal system.
Precision Climate Control with Mitsubishi Water-Cooled VRF
- 14 individually zoned Mitsubishi VRF systems provide flexible and efficient heating and cooling.
- Water-cooled technology enhances performance and energy savings in a high-demand residential setting.
Luxury Pool & Spa Heating
- Dedicated hydronic pool heating system ensures optimal temperature control for year-round use.
- Spa heating system delivers rapid warm-up and consistent performance for enhanced comfort.
High-Capacity Domestic Hot Water (DHW) Storage
- 1000-litre DHW storage system meets the high demand of a luxury residence, ensuring uninterrupted hot water supply.
- Energy-efficient design integrates seamlessly with the geothermal and VRF systems.

OUR TRUSTED PARTNERS

When we moved into our house last year, just as winter was setting in, we realised we needed to retrofit 2x 30yr old gas boilers for our underfloor heating system. After trying to get quotes, install times from other vendors, Radiant were able to come out on short notice and inspect our system / requirements. Sizing the system was quite complex given the type of piping used in original build, the layout of our house, expected usage of each section and the potential heat loss from single pane windows.
Within a few weeks, Radiant were on on site installing 2x new electric heat pumps including the relocation of DHW units / buffer tanks to make better use of our internal space. Once installed, our house was nice and warm throughout the depths of a Southern Highlands winter and the efficiency of the unit was much better, and I continue to gain efficiencies through minor adjustments (timer settings, buffer tank temperatures etc) which I discuss with the Radiant team. Been a pleasure to work with Jimmy and Josh

Stop before you do anything with your home heating or cooling, or specifically geothermal or with heat pumps, talk to these guys. We've had a very complicated geothermal heating system, multiple heat exchangers, underfloor heating, pumps and also water cooled AC.
Jimmy and the team were the only ones who knew absolutely everything that needed to be done to get it working properly, efficiently. Not only that they explained everything along the way and made sure the system and us as the users were operating it and it was properly setup. My only wish is that we'd engaged Radian Heating and Cooling earlier in the process it would have saved so much time and effort.
These guys solved lots of problems others couldn't and set the system up much better and with more reliability. They are always ready to answer a quick question and very responsive. I rarely write reviews but these guys really deserve the review and you'll be very happy you engaged them. Thanks Jimmy and team !

Schiavello Construction (NSW) was engaged by Waverley Council to finalise the construction of the Bondi Boot Factory Adaptive Reuse Project at Bondi Junction. Schiavello Construction (NSW) contracted the Geothermal ground heat exchanger header pipework scope works to RHCS, whom provided specialist input into the design of the pipework system to allow for an efficient and defect free installation.

The team at RHCS was a pleasure to deal with during construction & would recommend them for any future projects
