So we are the owners of a brandy new Entegra Vision 27A and it has a tankless hot water heater (girard brand). Formerly we had a Jayco class C 25 feet long and this one is 30 feet long.
Hubby is seriously thinking of ripping the girard out as it wastes some much water (about twice)...yeah we can catch the cold gallon of water that comes out when doing dishes or getting ready for shower but it is wasteful! Anybody have any insights that we haven't thought of? Pretty sure we will be taking it out.
We typically could last a good week and sometimes more in our Jayco but now not so sure.

Unless you are always in a full hook up site {and the OP is not}, tankless water heaters are water waisting disasters. ![[emoticon]](https://forums.goodsamclub.com/sharedcontent/cfb/images/doh.gif "doh") They will drain your freshwater and fill your grey tanks with equal speed. The venerable AC/LP 6 gallon water heaters found on most RV's have been doing their job well for decades.
My bride and I can take two quick showers and never run out of very hot water, even if I used it all the LP side will reheat the entire tank in about 10 minutes. We have steaming hot water at the kitchen sink in about 15 seconds and the shower/bathroom sink takes less than a minute. A full 40 gallon fresh tank lasts us nearly a week. In the warmer months we like to use the outside shower to save capacity in our grey tank and yes, these old folks always wear our swim suits {you're welcome}. ![[emoticon]](https://forums.goodsamclub.com/sharedcontent/cfb/images/biggrin.gif "biggrin")
Assuming you have the room for a conventional AC/LP 6 gallon water heater budget about $500 for the unit {the internet is your friend} and another $200 for the install. If it comes in for less hooray. I "could" do that install myself but it can be a serious PITA best left to a qualified RV tech {my Indie charges $90 an hour most dealers are around $130+}.
As always... Opinions and YMMV

Many people keep gallon jugs in the kitchen and shower to catch the cold water, then use it to flush the toilet, etc.

^^^^^ Is catching the waisted water supposed to be an improvement to the typical tank water heater?
Should I upgrade my 10 gallon heater and get a tankless so that I can catch the waisted cold water.
Tankless water heaters in an RV are not very well thought out.
There were designed by someone not logistically familiar with RV'ing.
Tankless heaters are a great option for a stix and brix home but they are not a good idea for an RV.

To be fair, there is also wasted water on the std wh setups at the outlets too. The further away a faucet is determines how much cold water is wasted.

I guess "waisted" water is water that you wear around your waist?
As Wildtoad pointed out, the water in the line between the water heater (regardless of the type) and the faucet will be unheated. So, yes, catching WASTED water is always a good idea when boondocking, regardless of water heater type.

I'll take the spelling lesson. But to the point the difference between a tank of hot water that is sitting there hot and ready vs. a coil that is sitting full of cold water waiting to be heated is significant in terms of how much water is wasted!The water does not reach temperature instantly, epecially when the ambient temps are cold.
I agree you may save some energy but you will waste additional water in the process.
I 've never ran out of lp or energy while camping But I have run out of water![[emoticon]](https://forums.goodsamclub.com/sharedcontent/cfb/images/frown.gif "frown")

We owned a moho with a Truma waterless hot water heater and we did not waste any water. I suppose by Winnebago placing the water heater by the bathroom it had a lot to do with it. Also, Truma heaters are supposed to be very efficient (and pricey.) I have been told by RV techs Girard water heaters are not very good.

I agree with the comments that on-demand water heaters in RV's are not necessary or even an "improvement" - especially when drycamping.
Our propane RV water heater is well insulated so it stays hot a long time without it needing to relight itself and maintain temperature. It uses very little propane anyway, and it heats up so fast that we just turn it on 15 minutes before we need hot water.
For optimum flexibility, I guess the only RV water heater type superior to a propane-only one would be a combination propane/120V AC one, so as to save a bit of propane whenever on hookups or to use a generator to conserve propane when drycamping.
