Hydronic Heating and Cooling Specialists

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 !
