dude please dont patronize me, i can read instructions, even spoke with the manufacturer, my mechanical skills are above average i do my own builds, ac charging,electrical,plumbing etc,...... i was given one and it sucked, perhaps it was the brand, i ran it with a really good pump and it fucked it up the pump bearings with the hot water...if you take water and heat it...and then continue to reheat it over and over it just get hotter, after a couple hours i had steaming black water in a res...

As for the shitload of water...so you run 30 seconds of water, how many times a cycle to keep filling your room? how many hundreds and eventually thousands of gallons do you just flush away to save 150 bucks on a co2 generator?


well?... honestly
your the only person in IC history that hooks up a co2 watergen
and in a mere 2 hrs has this--->after a couple hours i had steaming black water in a res

just trying to help ya out because you really need it,
I mean a 10yr old can see you obviously did many things very, very wrong to get to the point you have a steaming rez of black water in 2hrs...
and btw, t
if you take water and heat it...and then continue to reheat it over and over it just get hotter, in 2hrs....
how+why did the Co2 controller cycle that much in 2 hrs is another Q?
did you hook it up and just walk away, no testing, no dialing it in???
it's not a set it and forget it thing lol
something ain't right with that story, fuggin unheard of really?? :shucks:
btw my water bill is the same after adding it,
I'm sure the water dumped may one day add up to thousands of gallons of water, but realistically
u need a a big dose of perspective.
now...
how much water/nutes are wasted changing out a 100-200+gallon res every few weeks in coco, hydro set ups?
which btw,
speaking of coco, in your thread post#26
your draining to straight to waste in a drain from your coco beds
in a drought
in cali
gee, sounds a bit selfish lol:D
for drains i do 3/4 drains to totes that have a float valve to a submersible pump that goes outside the room to a drain

big LOL...your getting seriously bent up splitting hairs over idiot things in this thread and this is why it sounds a LOT more like its personal from ya
your calling me selfish because your in a drought in cali while dumping your water/nutes on a regular basis
and me 2000mi away in a near rainforest getting 70" of rain yearly and dumping water in a swamp... puleeez :D
you gots some real issuse there kiddo

i'm with zeet

the dehuey is a pretty critical component in a sealed gro,
especially for the nite time RH spike.
by the time i was wrapping up my room build funds were tite!
after looking at the commercial dehueys running $1500-$2000
and after talking to a few that have done this for a while I opted for 2 freidrich 50pt units @$250 each till i could get more funds for the commercial unit.,
they have performed well and are getting the job done for 9months now,
they do so well I'm not sure I'll pick up a commercial unit.
its a wait-n-see how long these last.

good luck and have fun!

The dehuey is critical for me with this style. I have use and killed many 70 pint big box store $250 dehuey's. I cant wait till I can get a $2000 green house one and I would recommend it if its in the budget. These cheap dehueys run about 10 amps and pull 70 pints in a day and have a hard time keeping up with a room like yours unless using 2 of them. The commercial dehueys run about 5 amps for 150 pints per day. These aren't exact numbers but close, so u can see twice the performance with half the energy at ten times the cost. That's my breakdown but performance and energy savings are worth the investment in my opinion. gl MM

He means why push air through the can when you can pull, I was going to ask the same thing.

Im pretty sure that was just a mis wording by KB but he can correct me if im wrong. U want to use the prefilter, so pulling would make more sense. Although u can put the pre filter on the inside and blow thru it, usually helps if u cant fit carbon filter in your room.

I have to agree. I've wasted a lot of time with the tankless water heater approach using a 55 gallon rez. I've gone through a half dozen pumps, and ultimately, the tankless heaters aren't reliable for what we are trying to do. From my experience, this has worked out to be penny wise pound foolish. Cool the room the right way and use a generator, imo.

I ran the numbers before buying and agree the bigger units are much more effecient
I'm all for getting quality equipment, and I did when I built my new bloomroom last year.
so after cost over runs by the time i was ready for a dehuey I was pretty tapped for cash and $1500-$2000 would have created a few probs so I opted for the 2 fried 50pt units after talking with a member here that lives in washington state.
i was pretty skeptical
but as he said,
I live a temperate rainforest and if my 2- 50pts can handle it here they can in florida.
trust me I didn't want to stoopid and lose my 1st crop to mold and would have gotten the commercial dehuey if I absolutely had to have it.
he's never steered me wrong sooooo... i took the plunge.
I figured after a harvest and fund situation looked better then i'd upgrade to the commercial dehuey.
mine have been online since jan and have performed flawlessly
i'm @35-40% Rh at nite.
so currently if it ain't broke don't fix it is the plan,

but again, i agree 100%, get quality equipment any time you can.

I have 6000w and use a 32,500btu mr slim mini split so I think I'm covered on cooling it "the right way".

"and ultimately, the tankless heaters aren't reliable for what we are trying to do"
why not?
it's no different than the one's like the hydrogen co2 genny selling on gro websites everywhere, right?
I mean you said so yourself here
exact same thing...buy the one with the 3 knobs or pay hydrogen 300% markup...


at the end of the day your burning propane/nat gas and getting Co2.
there's no big science involved with a gas Co2 gens or a tankless HW heater, well actually i take that back, a tankless is a more tech piece of gear.,
but bottom line i could put my gas grill in the room and it'll do the job if i hook i to my controller lol.

on yer pump probs, don't kno if you used a submersible or not
but after the 1st pump I would have been on that one figuring out why and not repeat the same mistake
especially doing it till 6 pumps were toast!
shucks.gif

it's obvious the proper pump was not used.
no big science here either,
simply get a pump rated for it's intended use within a specific temp range
got mine up for $64 shipped. a 1/6th HP submersible
I even screwed up and it ran dry for 2hrs---> TWICE LOL
it was over heated pretty bad...
but after it cooled it ran like a champ and I still use it so to fry 6 pumps in a row,..
somethings not right with that, unheard of really and just like sureshots pump fiasco
and both of you had the same prob, wrong pumps and the prob wasn't the tankless heaters
so to say the tankless heaters aren't any good isn't the case at all,
the only thing not good is you and SS66s using pumps in a manner it's not designed for.
bottom line it boils down to 2 DIY projects that ended up going south
with user error being the culprit and blaming the tankless hot water heaters

the cheap big box dehus dont have an AHAM rating, the number they advertise is calculated from a very highly saturated envirnment, and that dehumidification rate is what they advertise ie 70 pintsper day. Its deceptive to consumers and growers. These arent designed for us theyre for homeowners..AHAM rating is @ 80f 60h, typical growroom conditions, when you get away from that parameter your dehus effectiveness drops significantly.
i use a phoenix 200 max in one room and a dri eaz evolution in another, they both kick ass and come close to there advertised aham ratings..if you can get an AHAM rated dehu, if not dont expect your dehu to remove the amount the manufacturer advertises, more like 50-60% is my experience

You're quoting me when I first started with the project. Yes, if you are going to use the Hydrogen then the tankless water heater is fine. I'm suggesting a straight burner is the way to go. Cool it and forget the problems that come with plumbing the Hydrogens or the likes.

That's just my opinion after running the tankless setup for more than a year. It's higher maintenance than it is worth.

Gnome :wave: that you go and scour peoples past posts and then try and use their posts to prove your meanigless point is really fucking pathetic dude, really fucking pathetic. I was done dealing with this until i read your passive aggressive lambasting of that Heddokuyak dude and that changed my mind :woohoo:... Hendokuyaku HAD an opinion a year ago,he was sold on the concept. after using it he didnt like it, felt that it was a pain in the ass to run...SO FUCKING WHAT?? his OPINION changed AFTER his EXPERIENCE, thats the correct way one forms an opinion, have an experience. You went back dug up his post from a year ago to point out that he supported the concept then and hes contradicting himself now what are you the forum CSI Horatio Caine? dude get a job,get a grow, get something going... the growers i know,self included, dont have time to play Hardy Boys on a weed site. Your sardonic insults and attempts at belittleing a person when they just have a different opinion or have had a different experience is really insulting and indicative of someone with very low self esteem while simultaneously having a huge ego, you didnt get validated or praised so you had a spiteful tantrum.
That being said, your critical thinking is so flawed take the $200 bucks you saved (initially) and enroll yourself in a community college course for logic/reason...the analogy that i use water in my DTW equates to you using water for co2 production is ludicrous, i mean straight up nimwit brain....i HAVE TO USE WATER TO FEED MY PLANTS...YOU DONT HAVE TO USE WATER TO CREATE CO2..get it??? are you that challenged to see that...really dude just well, not bright. For your edicfication ill let you know i use 50% condensate water
Well, congrats on having some success collecting green dots on an internet message board, 4200 posts! my you are a helpful one! You have alot of free time i have 200 posts in 8 years, im busy with a thing called life.....you can be the online king dude, nobody cares. You can keep offering sardonic condescending insults under the guise of being 'helpful" to anyone that stumbles upon you here with impunity, its the internet. This is why Overgrow was awesome, people werent such unmitigated ****s to each other for having a difference of opinion (unless it was the breeder forum)

Bottom line with a water cooled co2 gen i didnt like the system, it took work, and my grow provides me with plenty of real work.I found it unreliable and more trouble than it was worth..i dont care if im the only guy ever with this opinion, its just my opinion...Hendokuyaku feels the same way, no big deal Gnome its just opinions...heres the math...you run it every hour for 30 seconds @ 4 gallons thats 48 per day and a month of veg is 18,288 gallons per year of water.. but it hasnt cost you a dollar more on your bill right? ..congrats you saved $200 and have the most l33t hi-tek co2 burner in like, the world,really hi-tek stuff you had someone HELP you build...i respect that you like this setup, apparently you reallllly like it alot,i believe if it had nuts you would hug them, long and tight i found it, past tense because i HAVE experience with it, to be penny smart, pound foolish and not something i choose to run...im done talking to you man i feel my iq drop when i read your posts. Im not anything like a hippy or conservationist im a grower, i do this professionally and do it as responsibly as possible, im not interested in saving a buck( then it costs a buck) by dumping a shitload of water, thats just dumb

man oh man...you guys are getn' a lil hotter than needed over this topic, aint like we're splitting atoms round here:biggrin:


Anyhow...im going to go with a propane setup, I have no gas at my building, only electric and water


Does anyone have a great system they could recommend??? link maybe?

and what is a time schedule to feed the room with the Co2???

Im 100% new to this idea and don't really have a clue on how to setup my fans, timers and the like to make this all jive correctly.....thanks to all of you guys, even the bark-fest about the topic, being passionate is how we make advances in things, this being no different....so thanks again and lets keep it cool here cuz we can!:moon:

Fwiw I have heard good things about the tankless water heaters, whether they are used recirc or dtw.

Hey gnome would a 50 gallon reservoir outside when it's in the 50's at night be cool enough or do you think it would get smoking hot. I had thought about burying coils of pex maybe before and after the res but really would prefer not to (digging sucks and I can't get a tractor in there).

I would run to waste but I'm a little nervous because of the amount of ro I make already, had thought of using the ro waste to cool with but I assume it has so much ca in it that it would in short order start to fuck stuff up.

the atlas 3 controller is good, reliable and doesnt need water around 300 bucks u just need to check websites :D the titan 4 burner propane burner is perfect for that setup...put the controller across the room from the burner, opposite walls...they will connect with an extension cord when the co2 drops below its setpoint 1300, the controller will signal the burner thru the extension cord which is now plugged into the burner and screwed into the propane..this will fire the ignition switch, tripper the propane and will burn until the controller reaches the setpoint, i picked 1300, then it shuts off...it has a photocell so it only comes on when lights are on...follow the instructions on hanging the burner it needs to be life over a foot from the wall and ceilng, they give u hooks and chains to hang it

check amazon the controller is 335 and the burner 330, all u need is the propane and your goin

I know you didnt ask me, but I hope you don't mind if I chime in. I run lights at night under those conditions you listed, and I can tell you that the water STILL gets very very hot during lights on. I can't imagine how hot it would run if I ran during the day (close to 100s)

In your opinion is it exceptable though? I suppose using copper piping would be a good step in making sure that you don't end up with a hose blowout. I can't imagine what those heaters could do to a traditional 1/2 or 3/4 hydro style hose. Maybe rough in 3/4 copper coming and going and use SS braided lines to connect to it? Or pex I guess, that stuff carries some hot water without problems.

I also thought about getting an old radiator of some kind of and using a 160-200 GPH pump through it, separate from the water heater line, might take some of the heat load off the water.

All that stuff starts to get complicated though, pretty soon shit can get out of hand LOL.

Hey gnome would a 50 gallon reservoir outside when it's in the 50's at night be cool enough

i had a 32 gal rez/trashcan in the room,
it stayed a bit warmer over ambient room temps.
TBH, it felt like lukewarm tap.
quite honestly takes a real effort @screwing things up to accomplish the probs posted earlier ;)

ok.. thought on it
AND
i ran the w-heater and filled up 1/2 a 5 gallon bucket which is more than the 30sec controller would cycle it.
with the flame/temp level set on low on the tankless
temps are 101F directly in the water stream,
putting your hand in it , its luke warm as i said above.

regardless if your 50gal rez is outside in nite 50 temps
i don't see a prob at all theother :)

these tanlkess units have been in use by IC members and selling as the hydrogen Co2 gens at websites for years now.
Ive yet to see the threads and posts piling up with probs mentioned earlier by SS66 and HDY?
in fact I've yet to see 1 single post?
the only 2 probs with them are with 2 sS66 and hdy using the wrong pumps in a res application.
the only prob i see now is for over a year HDY never posted once about the probs
or that he even had one even after destroying 6 pumps?
neither did SS66 with all steamy blalckwater rez probs?

as i posted earlier to ss66 and hdy,
something ain't right with the story, fuggin unheard of really??
BTW, anyone seen coconutz around lately??
I heard he was banned... again :smoke:

For my conditions, I don't think it's acceptable. Don't forget that the hot water is going to heat up wherever your rez is as well. I think the only time to consider it would be if you have no way to cool the environment anymore and you've perfected it so much that you only have Co2 to add.

To be honest, you seem a little coconutz to me. haha. :) Have a good one. I'm just playing around.

I will say that though that my 55 gallon rez temps using the tankless water heater were about 170 degrees in my 300 sqft sealed room. Maybe your room is smaller? We're not on the same page I think.
