Your Home Generates Solar All day.
Your Gas Boiler Ignores Every Bit of It.
Thermal Dawn connects the two — storing your daytime solar as heat and delivering it through your existing radiators and underfloor heating, all evening, for free.
Works with your existing radiators and underfloor heating. Australian-made. No gas. No peak-rate pain.
A Standard Heat Pump Still Leaves You Exposed
Swapping a gas boiler for a standard hydronic heat pump is a step forward. But it doesn't solve the fundamental problem: your home needs heat most at dawn and dusk — exactly when electricity prices peak.
A standard heat pump draws from the grid during those expensive morning and evening hours. You've escaped gas, but you're still paying premium rates every time the temperature drops at night.
Thermal Dawn is different. Our system charges during the day on your solar — storing thermal energy while the sun shines and rates are low — then delivers that stored warmth through your radiators and underfloor heating all evening, without touching the grid.
What This Actually Means for Your Bills
$800–$1,500/yr
Typical annual savings vs. gas hydronic + grid electricity.
3–5 years
Typical payback period with existing solar.
15+ years
System lifespan — no degradation, no replacement cycle.
Gas prices have risen over 40% in five years and aren't coming back down.
Every year you stay on gas is another year paying for an energy source with nowhere to go but up. A Thermal Dawn system locks in your heating costs at near-zero marginal rate — your morning solar — for the next two decades.
Savings estimates based on modelling of a typical 3–4 bedroom home with existing rooftop solar replacing a gas hydronic system — actual savings depend on your home size, climate zone, solar capacity, and tariff structure.
Same Pipes. Smarter Heat Source.
Upgrade your Thermal Dawn system to include hot water heating. The same thermal storage that powers your heating and cooling can also deliver hot water—maximizing your use of dawn solar and cutting even more off your energy bills.
Step 1
Charge on solar
During the day, your solar panels power the Thermal Dawn heat pump, storing heat in our Australian-made thermal tank. No waste, no export at near-zero rates.
Step 2
Heat your home for free at night
When the sun sets and your family comes home, stored thermal energy circulates through your existing radiators and underfloor heating — keeping every room at the right temperature without drawing from the grid.
Step 3
The system learns your home
Our AI optimises charging times based on your solar forecast, local weather, and your tariff schedule — so you're always comfortable and always on the cheapest possible energy.

For most homes, the retrofit is straightforward — Thermal Dawn connects to your existing hydronic pipework in place of your gas boiler. No new radiators, no major plumbing, no mess. A free site assessment confirms compatibility and gives you a fixed quote with no surprises.
Most Hydronic Homes Are a Straightforward Retrofit
If you have an existing gas hydronic system with radiators, underfloor heating, or fan coils — you're already most of the way there. The main questions our site assessment answers:
Is your existing pipework in good condition?
What's your heating load, and what is the right capacity?
Where does the thermal storage tank go — inside or outside?
Does your switchboard need an upgrade?
We flag everything upfront. No surprises on install day.
