Thermal

Thermal puts your geyser in your pocket. Monitor live tank temperature, track energy and water usage, schedule heating, and get alerts — from anywhere.

WHAT YOU CAN DO

• Live status — top, middle and bottom tank temperatures at a glance, with an online/offline indicator.
• Operating modes — switch between Off, Element + Heat Pump, Heat Pump Only and Element Only to balance speed and efficiency.
• Boost — heat to a higher target on demand; the controller manages the cycle for you.
• Heating windows — schedule when your geyser heats to match your routine and save on power.
• Usage insights — daily energy (kWh) and water (litres) with cost estimates.
• Alerts — low-temperature and rapid-drop notifications so you catch problems early.
• Secure account — manage your profile and password; your data is encrypted in transit.

WHY USE THERMAL

Thermal is designed for homeowners who want a hotter shower for less — clearer control, less guesswork, lower bills. You'll need an account from your installer/provider to sign in.
