@LSU_postman, how does the 7.0 gallon work for your entire home? I am about to install a 9.0 gallon and wondering if its big enough for a 2600 sq ft home?? Appreciate any info

You might be underestimating how big of a generator you need to run a tank less water heater.

I have a 10 gallon for 3000sq ft. I think the # of faucets is the more important factor. We have 3 full bath, kitchen, and laundry sink. Haven't had an issue yet. 9 gallon should be perfect. Only issue I have is that it takes longer to heat up than my old tank heater.

The OP didn't say whether he wants a gas or electric tankless water heater and different posters are apparently assuming different kinds.

He said to "run a..." without asking which kind.

I didn't want to go too small. It will be electric and I don't imagine I'll be needing to use hot water when the power is out.

@jmorr - yeah I’ve heard that....especially if it’s a long run across the house. Mine will be installed on the opposite side of my master suite which I am assuming will cause a delay. Thinking of adding a medium size tank heater on one side of the house to help with the delay and to avoid any issues when the power goes out. Thanks for the info

We have a 9.9 gpm tankless propane Rinnai, and it only consumes 81 watts while running, 1.3 on standby. Your generator won't even notice it.

Electric tankless are power pigs. The only way an electric tankless makes sense is for a small point-of-use heater.

If you're having noticeable delay times consider having a recirculating pump and required piping installed
