Understanding the Need for Battery Backup

I learned that tankless water heaters operate on electricity, which means that during a power outage, I would lose access to hot water. A battery backup ensures that I can still have hot water when I need it most. Whether it’s for showering or doing laundry, having a backup system gives me peace of mind.
