3 smart reasons to connect your water heater to Hilo
Hot water is cozy — but did you know it can account for up to 20% of your electricity use in winter? Now there’s a smart way to take back control: by connecting your electric water heater to Hilo. That way, you’ll still have access to hot water in moderation during peak demand events — without putting your savings at risk.
Two ways to connect your water heater:
- Get the Hilo smart water heater controller (available free of charge1)
- Pair your Calypso water heater controller with the Hilo app
Here are three smart reasons to get started!
1. Maximize your savings
By automating your water heater during peak demand events, Hilo’s smart solution can help you save an average of $302 per season, depending on the size of your unit!
2. Enjoy more comfort during peak events
No cold showers here. The controller lets you use a moderate amount of hot water during peak demand events — roughly 25 minutes’ worth with a 60-gallon tank3 — without cutting into your energy savings.
3. Optimize your electricity use
With the Hilo app, you can monitor your electricity use in real time — including how much your water heater is using. Better visibility = smarter energy choices = more potential savings.
Already have a Sinopé Calypso controller?
Good news! Both the Zigbee and Wi-Fi models of Sinopé’s Calypso water heater controller are compatible with Hilo. Just pair yours with the Hilo app to benefit from automation during peak demand events and maximize your savings. Plus, you’ll receive a cash bonus of up to $1254!
Want to save even more? Add Hilo’s other smart energy solutions — like thermostats or a compatible EV charger — alongside your water heater controller for even greater impact.
