I have a Navien tankless heater and really like it. However as all mechanical devises, it will break (which it has done yesterday). My idea going forward if it breaks again is to insert valves in hot and cold lines to temporarily hook up small 110volt heater. Does anyone have better idea for a temporary source of hot water?

Sounds like a plan, In my experience Navien is the worst.....and I never pass up the opportunity to say so.

Navien earned that from me.

And that right there is the reason I changed from tankless to a tanked water heater a few years ago. They seem to be way too finicky to be used as the primary source of hot water
How about doing a 40gal electric tank that’s fed by a tankless ? That’s the cats butt in my opinion. Pipe it so you can bypass either one and operate just one source.

Dual fuel 🤓

Southern California,
I have a better idea. After the 40 gallon tanked water heater, add a 40 gallon natural gas water heater. That would be a tri-powered system.

Better yet, 4th in line could be to borrow someone's grandma with a 20 gallon kettle over a wood fire, to ensure ample hot water. They say quad-powered is the bomb!

Heater repaired. Lee Company tech from Nashville came out yesterday. Internal check Valve failed and piece of plastic lodged in flow sensor. Happy to have hot water! Oh, by the way, tech works on all brands and in his opinion, the Navien is the best!

I have a 50 gallon gas Rheem being fed by the Rheem tankless. Think all tankless (as compared to tanked units) are finicky, and yes they do require maintenance, but IMO its worth the minimal hassle. With that being said there have been a "few" times I was glad the tanked unit was there.:)

This water heater doesn't have the same continuous energy losses as storage water heaters, which might help you save money. Here are the link reviews of water heaters. Here you'll learn the basics about tankless water heaters, including how they operate if they're ideal for your house and how to choose the correct type.
I don't see the link.
I'm interested, please post.

For a much simpler system, have Gilligan riding a bamboo bicycle that pumps a recirculator, while Maryann and Ginger feed coconut shells into a boiler.
