Tankless Water Heaters

It's a tankless job, but somebody's gotta do it!

Ba dump, dump!

Not the hardness of the water that matters, it particulate matter. Water is filtered before getting into the heater.
I have, generally, very good water (Hetch-hetchy from the Sierras). I expect the heater to last as long, or longer than a furnace, ie 20+ years.

Yep - we had a tankless for a few years at the lake. We draw our water direct from the lake and last year the impeller and flow sensor/switch finally died on the heater. Once too many times with sand going through it. Hard to avoid even after taking all the usual precautions - it’s very sandy where we are and the tankless is quite sensitive to that.

That said, it was awesome before I killed it!

Thank you. Did I babble too much? Sometimes I babble too much. Sometimes I blither adnausium. Sometimes I just ramble on to a degree of total lunacy. Oh crap , I'm doing it again. Sharkbait out.

No way bro. I think it's really awesome when someone as knowledgeable and skilled as you are takes time out to educate the rest of us.

The OP (I think) said you don't have natural gas in your house? You might need to have a heavier duty electrical circuit run over to the heater. I only worked on one electric tankless when I was in HVAC and I don't remember what size the wires coming into it were but they were big. Just mentioning as it could be a significant extra cost.

...endless hot water...

You guys have an endless water supply in California?

Friends have a tankless about 10 years old. It has the recirculation system that pumps hot water through the house continuously so you always get instant hot water. The circulation pump has failed twice. Something else failed too, a thermostat or something.
