Can I still get hot water if the power is out?

If you experience a power outage, your Rinnai Tankless Water Heater will notĀ operate. However, it can function if you have a battery backup system, available as an accessory from third party vendors. While Rinnai does not sell these systems, we recommend you speak with your licensed tankless water heater installer, who can point you in the right direction.
