Tankless Water Heater Battery Backup

Are Power Outages Leaving You Shivering Under Cold Showers?

Your tankless water heating system provides you with an endless stream of hot water for taking showers or washing your hands. But what happens when you experience a sudden power outage? Your household is left with no choice but to use frigid water.

The good news is that it doesn't always have to be that way. With our heavy-duty battery backup in place, you can keep your home supplied with hot water through power disruptions.

The Battery Backup for Tankless Water Heaters lets you enjoy the comfort of hot water even while the power is out.

Keep The Hot Water Flowing

Install the Battery Backup to serve as a backup energy source for your tankless water heating system during unexpected blackouts.

If your household uses hot water for 1 hour every day, can supply your home with up to 7 days of hot water usage or up to 13 hours of direct vent heating. This backup battery automatically activates as fast as 8ms after the main power goes out.

If a power outage occurs while you are in the shower, keeps your tankless water heater running continuously without restarting.

Conserves Energy

Unlike traditional UPS systems, won’t fizzle out just a couple of hours after the lights blink out.

Optimized for performance, our power supply only starts converting DC to AC once your faucet or showerhead is turned on, thanks to a patent-pending flow sensor.

Its sealed lead acid battery is easily replaced. If you’re expecting a season of intermittent power or supplying a small business, you can parallel batteries together for longer runtime.

Withstands Cold Weather

Heat exchangers inside your tankless water heater can freeze during the wintertime. This can lead to property damage and costly repairs.

Our backup power supply features an integrated temperature sensor. During a power outage and with the flow sensor activated, the temperature sensor forces the backup battery to run at 37°F or lower. By doing so, keeps your tankless water heater's anti-frost running even when temperatures drop
