1KOMMA5° AustraliaThe Heartbeat of New Energy

We believe it's time for New Energy

1KOMMA5° is Australia's Heartbeat of New Energy. Our vision is for Australians to live on sunlight and wind forever for free, by providing access to the cleanest and most affordable electricity possible.

Founded in Germany, our name says it all, and translates to 1.5 degrees (1=1, KOMMA = Decimal, 5=5, ° = Degrees). This speaks directly to the Paris Climate Agreement, preventing a further global temperature increase of 1.5°. 

We believe New Energy is the answer: Tailoring renewable, flexible, economical and care free solutions for Australians..backed by German development, technology and design.

Innovative Solutions

Heat Pump Hot Water Systems

Heat Pump Hot Water systems are an innovative solution for providing hot water in an energy-efficient manner. Unlike traditional water heaters that rely solely on electricity or gas, heat pumps extract heat from the air and transfer it to the water in your tank.

By using solar energy to power the heat pump, you can achieve near-zero operating costs for your hot water system, making it one of the most sustainable choices available.
