ABOUT
We’ve teamed up with Rinnai NZ to trial new tech designed to optimise how your hot water is heated. With hot water accounting for around 30% of household power use, we'll be studying the impact of smarter heating, to help ease pressure on the national grid.
WHAT TO EXPECT
If you’re selected, a small device will be installed next to your hot water cylinder. It connects to a cloud-based platform that learns your household’s usage patterns and schedules heating times according to grid conditions. All while making sure you have hot water when you need it.
The trial will run from 26 June to 31 October 2025. During that time, we’ll ask you to complete a few short surveys to help us better understand your experience.
WHAT’S IN IT FOR YOU?
If you're selected, you’ll receive a total of $250 in account credit — with $100 applied at the start and the remaining $150 if you complete the trial.
