How Delta gets your geyser under control

A smarter geyser does not need to mean a complicated installation. Delta connects to your existing electric geyser and gives you remote control through your smartphone app or online dashboard, allowing you to easily set your geyser temperature and heating schedule, so you only heat water when you need it.

1. Install it on your geyser

Delta is fitted to a standard electric geyser by an installer. No complicated installation, no reworking of plumbing, just a simple connection to give you better control.

2. Connect to the dashboard

Once connected, your geyser becomes visible from the EASIWise dashboard. Set schedules, check geyser performance and manage settings from anywhere.

3. Let it heat smarter

Set timers and temperature settings, plus boost and holiday modes so you only heat the water when you need it and keep the geyser off when you do not.

4. Get alerted when needed

Delta can notify you when leaks, sensor issues, overheating or unusual heating behaviour occurs. The system can also help stop the water supply when a leak is detected.*

Smart control without the hassle

Your geyser should not need a daily committee meeting. With EASIWise, the important controls are easy to reach, whether you are at home, at work or halfway to the coast.

Smart schedules

Schedule your geyser to suit your lifestyle, so it only switches on when you need hot water.

Boost mode

Need hot water outside your preset schedule? The boost button heats your geyser to your desired temperature outside of your regular settings.

Holiday mode

Away for a few days? Stop heating water nobody is using at the click of a button.

Temperature control

View and manage geyser temperature settings from the dashboard.

Usage visibility

Alerts that get there before the problem gets expensive

Most geyser problems are only apparent when it’s too late, becoming inconvenient and costly. Delta is designed to make important issues visible earlier, so homeowners, support teams or insurance partners can respond sooner.

  • Leak detection support: Connect a leak sensor at the geyser or drip tray for early detection of a burst geyser.
  • Optional automatic shut-off: Add a water shut-off valve so the system which will stop the water supply when a leak is detected.
  • Remote fault alerts: Receive alerts for important geyser errors, including leak detection, over-temperature warnings, sensor faults and abnormal heating behaviour.
  • Support visibility: Alerts can help the right people understand what is happening sooner, allowing the issue to be sorted out before it becomes a costly problem.
