Power vent water heater and power loss??
I will be getting a power vent water heater soon. I understand that means I won't have hot water in the case of a power failure. Will I at least be able to use the hot water that is in the tank when the power fails and how long will it stay hot? (it's a nat gas. .63 eff Bradford White). Yes, I have to get power vent due to getting professional air sealing being done.
What could be done to enable me to have hot water if I did lose power for an extended period? How much would it cost?
I probably wouldn't stay in the house once it started to get really cold. Hopefully I'd be able to go somewhere else....but in the event of an ice storm or something it would be nice to have hot water and my fireplace to get us through.
