Smart water heater switch: hot water at the press of a button

Forget the old water heater routine. Meet the new generation of water heating: a smart switch for your electric water heater that changes the way you heat water at home.

What is a smart water heater switch?

A smart water heater switch is more than an electrical switch that replaces the old water heater button. It gives you full remote control of your electric water heater from an app on your smartphone or tablet, or even by voice. Today’s advanced smart switches are a new generation of water heater controls, with capabilities that weren’t possible before.

Unlike a regular water heater switch, which you have to be next to, a smart water heater switch lets you control water heating from anywhere: the living room couch, the office, or even while you’re on vacation. That way you can make sure you always have hot water exactly when you need it, without wasting electricity on unnecessary heating.

The benefits of a smart switch for an electric water heater

A smart switch for your electric water heater brings many benefits that make everyday life more comfortable and efficient:

• Remote control anytime: turn the water heater on, off or set a schedule from anywhere with the dedicated app. Driving home after work? Turn on the water heater 20 minutes before you arrive, and the water will be hot exactly when you need it.
• Energy tracking and monitoring: a smart water heater switch measures electricity use in real time, so you can see how much energy the water heater uses, calculate the monthly cost and spot inefficient usage patterns.
• Smart scheduling and advanced automation: set up routines and automatic runs, for example turning on the water heater every morning half an hour before you wake up, switching it off automatically after two hours, or turning it on every Friday ahead of the weekend.
• Integration with smart home systems: a smart water heater switch fits easily with other smart home systems and can be part of complex scenes, such as “Going to sleep” (water heater off, lights off, alarm on).
• Significant electricity savings: because you control exactly when the water heater runs, you can save up to 30% of your water heating electricity costs. Advanced smart switches include an accurate power meter that helps you track your actual savings.
• Improved safety: get real-time alerts about faults, excess consumption or sudden disconnections. A smart water heater switch includes protection against overload and overheating, which improves safety and extends the life of the water heater.
• Advanced fault diagnosis: detecting potential problems early can prevent costly damage to the water heater and to your home’s electrical system.

Advanced technology in a smart water heater switch

Smart switches for electric water heaters come with innovative technology that makes them leaders in their field:

• Water temperature measurement: heats water efficiently, only as needed, to save electricity.
• Accurate consumption metering: advanced sensors provide accurate, real-time data on electricity use.
• Compact size: thanks to their small size, the switches fit easily behind existing switches without any changes to the electrical wiring.
• Handles high loads: support for high loads means you can connect large, powerful electric water heaters.
• Built-in protection: protection against overheating, overload and short circuits ensures maximum safety.
• Broad compatibility: works with Alexa, Google Assistant and Apple HomeKit, and is ready for the new Matter standard for consistent connectivity between smart home devices.

Simple installation and everyday use

Installing a smart switch for an electric water heater is relatively simple and can be done by any licensed electrician. The switch connects between the existing water heater switch and the water heater itself, and in most cases no changes to the existing wiring are needed. After installation, simply download the dedicated app (available in Hebrew), add the switch to your home network and take full control of your water heater.

For everyday use, the app offers a simple, friendly interface that lets you:

• Turn the water heater on and off instantly
• Set timers and fixed run times
• View electricity use statistics
• Create complex automations and scenes
• Get real-time alerts and notifications
