This is the battery backup that I use for my tankless water heater. Within this video, I demonstrate how to connect a tankless water heater to a battery backup. In the event of a power loss, I should still have hot water as long as the battery inside of my battery backup has a charge. Many people will try to charge an astronomical amount for a tankless water heater battery backup and tankless water heater battery backup installation. The reality is that a battery backup for a tankless water heater is somewhat inexpensive and connecting a battery backup for a tankless water heater is a simple DIY project for most people. #TanklessWaterHeater #BatteryBackup #DIY #HomeUpgrades
