Cinsa Basico Water Heater
I have a very small propane water heater, a Cinsa Basico Model 101, 38 liter, that is about 4 or 5 years old. It has had very intermittent use,
probably less than 20 hot showers per year as we don't need it in the summer and has always been out side within reach of the salt cedars. I moved it
to a better location and intend to replace it.
In downloading the instructions from Cinsa's website, I noticed that they said do not use PVC on the hot water side, not even C-PVC, but that horse
done left the barn. I've connected the water heater to the PVC with a faucet hose. Not even a pressure relief valve, heh.

So what's the problem with PVC caring a little hot water?

if it's PVC designed for the temperature, no problem.
if it's regular old PVC, hot water (esp very hot water) will eventually degrade pipe and glue.
what's done is done, maybe it will last, maybe not.

I can't find it, but I remember reading somewhere that PVC will fail around 150 degrees. Like mtgoat says the glue fails and the pipe walls weaken..
Maybe if you keep the temp down it will last longer? I'd be most worried about pipe that may be poured into the floor or foundation, and not knowing
a leak may exist below the house.

Ahhh Here it is: It' from some plumbing bulletin board:

I have been in the Plumbing trade for nearly 4 decades and throughout that time every time I noted a change to the codes I made it a personal point to
find out the underlying reasoning for the changes. To date I have yet to find any change that does not make perfect sense once you find out what
prompted the change.
It was soon discovered that PVC will exhibit wall softening and glue joint failures at temperatures approaching 150degF, which explains why
the ASTM standard for PVC now limits it to applications not exceeding 140degF. )
The PVC formula was then improved upon to create CPVC which can withstand temps up to 190DegF for a short time.

Jim,
Nothing to add re PVC.
I want to compliment you on your place. You really did a nice job with the back area. Who did your cement/rock work?
Nice steps to the deck too. How many beers do you charge for your consulting services? Going to be down mid summer by any chance...

Jim,
Nice house! But if you don't intend to get more reading in (see bookshelf in photo), you should use the wood to box in the ugly hot water heater.  I do not take my own advice. My hot water is ugly too, and it is exposed for God
and all his little lambs to see. I have an excuse though. I read a lot!

Santiago,
Not even a pressure relief valve.
You only need one of those for the second before the tank blows.
But it's a money saver.
Just don't be too close when it blows.

youse all (how my polish buddy from Alabama says it) are funny. Paulina is soooo right.
Vandenburg: not only is there no releif valve (I have one but never got around to putting it in as my buddy decided to see what would happen if we
starting sipping tequila before noon). The really bad thing is that the pilot doesn't work so I set a really big rock on the pilot valve, heat up the
thermocouple with one of those flame thrower thingys until the main burner lets fly. The echo dies down after a few minutes......... By the way - why
does the main burner light only when I can't stand it any more and lower my head down so I can peek in the door???? I've had to get eyebrow
transplants.

Hey, at least you have an idea how those things operate. More then you can say for most folks.
Had rentals in Sacramento, and waterheaters were one of the things most often failing. Replaced a chitload of them. Fun, when inside in a closet (
olden days ) with the minerals plugging the drain over the years, and having to wrestle a full 40 gallon one out the door. Still cussing just thinking
about it.

hey amigo...hmmm...that rock work design looks familiar...did you do it? Ya need to make sure to tell the rock guys to be careful with the cement
gusano and not get it on the rock as it's hard to clean off after.
Now, about that salt pine...you probably know that those buggers drip a real toxic sappy liquid which stains everything under it...so maybe you want
to consider moving stuff out from under it at night so the morning dew drippings dont trash your chairs etc.
How come you didnt just use c-pvc with that rustic water heater? I am really happy with this cool KALOTRON 20 liter porcelain lined water heater...it
is so small, we mounted it right inside the shower so no rust issues. I get a nice hot long shower as it sort of heats up as I shower as long as I
dont turn on the hot water tap full but just half and only takes 10 minutes to heat up and uses very little power. I tried to get another one for a
rental and couldnt find one though.

This is how "not" to hook up your water heater.
Not mine, pulled it from the internet...
Haven't had a bad trip yet....

CPVC and Water heater
I hate to jump in so late in this thread, but I do know how to hook a water heater to CPVC without leaks. This is based several years of leaks where
the CPVC connected to the hot water outlet. A plumber friend saw me fixing another leak and he said the only way to not have a leak is to install a
section of copper flex into the tank and then hook the CPVC to the flex. Five years later and still no leaks! The copper flex is designed for water
heater installations and seems to insulate the CPVC from the high tank temperature- the metal tank is hotter than the water.

BajaWarrior,
At least the one in your photo is in closet of sorts, so the the neighbors don't have to look at it.
Santiago, decorate your heater like the old green truck door that used to be south a bit. Cover it with race and surf stickers and treat it as yard
art. When it dies, you can put it at the Camp Gecko entrance with an arrow to your place so people will know where to go.
sounds good to me.
