And there is your quart. the Tankless has hot water coming out the outlet within half a cup.


Go home. Turn on the shower. How long before you get hot water out of your tank type water heater?

The only disadvantage to Tankless is you have a minimum flow rate before it heats.

There is definitely a delay with tankless. A tank heater has 130º water ready to go. A tankless does not. The cooler water in the pipes is a factor for both. Tankless does not produce hot water instantaneously. It takes a few moments for tankless to produce hot water. You will notice the lag or delay with tankless in a house or RV.
That said tankless is a very bad idea for an RV.
My 10 gallon tank water heater gives me unlimited hot water. I never run out.
Having unlimited hot water via tankless is a fallacy.
You don't have unlimited supply nor do you have unlimited waste water storage.

Agree. We would never have a tankless, nor a 12v fridge as both seem to the norm with the newer RVs. As for the tankless, friends of ours reported filling a dish tub full of water before it even got hot, hence he installed a mod noted in my other post. We have a tankless in our house and even with the water at full blast, there is a delay up to a minute for the faucets furthest away from the tankless. In that delay, an easy two gallons can be collected.
