Tankless water heater

Is it normal to always get cold water for quite a few seconds before you get hot water? That's a lot of wasted water

Yes. There is water in the line from the heating coils to the shower or faucet that must be displaced before the heated water comes out.

Iíd say thatís the downside of these. Depends too on how close the faucet is to the heater. Same as a traditional heater there. In my unit the shower and bathroom sink get warm pretty quick, but kitchen takes some time.

Some have a flow adjustment on them. My Furion does. Set to max. Iím thinking that would allow a larger volume of hot to mix with the cold. Iím still learning about it though. May be wrong there.

Absolutely wastes water and holding tank capacity. Not good when dry camping. I hated mine so much I swapped it out for a tank model. Couldn't be happier.

Yes, I have one in my house. Every time you turn on the hot water faucet, the burner must purge the flame chamber, before the burner can light. This takes a couple seconds.

I would not want one in my camper.

Here's a couple links on installing a shower miser. We've had 2 campers that came with it and it does work as intended.
