Well N A, The Tankless Water Heater is the Bomb!

god i wish i knew how to do all this. You've got 1 nice setup.

Hi all I am late to this thread but found it while searching to find SOME remedy for my ongoing Hydrogen CO2 generator issues. I am now on my fourth generator and I am just about done trying to keep one working. And while the company has been good about returning the broken units and giving me new working models it is all time consuming and frustrating.

The good news is I have a swimming pool that I have been using as a cooling tank. It works great as I get my pool heated and co2 for my room at the same time.

So my question is does the water being heated also "cool" the unit. Someone mentioned that the cooler your rez water the cooler the air from the vent? Can you please tell me a bit more on how this works. My room runs a bit warm in the summer so I need to avoid a burner if at all possible.

But I have to do something because once you have grown using CO2 you can never go back!

Any advice is greatly appreciated!
Many thanks

Simple physics my friend. The heat has to go Somewhere. The heat from the burner is absorbed by the water. Wish i had a swimming pool although i am seriously thinking about running the water through polyethylene tubing under my first floor to heat the house in the winter.

can any one recommend a pump that will work with an eccotemp heater? they wont work with a sump pump cause it has the flow restricter on it so the sumps just shut off. I'm going on my third transfer pump the first was good ran for 5 months or so now the second is going out and it only been a month or a bit more, they have to be oiled daily which i never do cause i'm not there. any suggestions..........?

damn, that's a great deal on a pump!

This is the one I have...

It was $40 on sale when I got it. Some say it broke on them. Mine has been running about 4 months with no issues.

thats the first pump i tried when i was getting started, but it wouldnt keep constant pressure when the flow regulator on the heater restricted the water so much. It just shut off due to lack of flow

Legally, how are you using the wort chiller? I just bought one on impulse, and now Im not really sure how I should be running it. I do have a fridge close by my rez, but im afraid of what dirty harry said

how bout that jacuzzi pump a few pages back? seemed like the perfect pump for this app. Little pricey though.

I ordered the AQUAH 6L Tankless Heater today. It was 149.00 plus about 20 bucks for shipping. I am hoping it will just slide right into the place my HydroGen heater left.

I called HydroGen and spoke with them and told them that I have replaced their unit 4 times over the past 2 years. They mentioned that perhaps the chlorine from the pool was causing issues. I replied that their manual states that a pool or hot tub may be used for cooling. Long story short they sent me a shipping form so I am returning it so they can take a look and see what is wrong. If it is a mechanical issue they will pay all costs. If not I will tell them to keep the unit as it is just too much trouble for its worth. i only paid for the original unit and my Local Hydro shop replaced it each time for me. So worse case scenario I got a few years use for about 375.00.

Now I am wondering if the chlorine will be an issue with the AquaH unit as well?

I will check back in and let you know what happens moving forward.

what is failing on your hydrogen? All the chlorine should do to it is keep it real clean. Short of eating through the brass or causing seals to fail prematurely, I can't imagine what it could do.
I remember their youtube video where they are using discarded nutrient water through it.
I would think the ignition system would be the weak link. I can't imagine they were built for continuous duty. More like RV or camping use. Curious about this.

I finally got my heater all hooked up. My room is not totally sealed and it's turning on every half our or so it seems like. How often does your guys run?

I have had 4 of these units so far. Not sure why they stopped working. Initially we went through all the troubleshooting steps and sometimes got them working by cleaning the small metal filter or cleaning the sensor but then eventually all our efforts would fail and we would take it back to the Hydro store and they would replace it. FYI our local Hydro store is no longer carrying them due to all the problems.

After the 3rd return we were upgraded to the PRO version and have had it for about 6 months and it is shutting off after coming on for 8-10 seconds. We have ran through all the normal trouble shooting steps and nothing is working. I am sending it in and they mentioned the Chlorine issue. As I said it did not make sense to me as well as their own manual suggests using a pool or hot tub for cooling. I told this to the guy on the phone..,"Why would you suggest using a pool or hot tub if chlorine is a possible problem to rubber seals etc." He then back tracked and said "well it's probably not an issue." He said all parts are covered with warrenty but condensation is not. Not sure what might cause condensation. I run a dehumidifier and keep room at about 50% humidity.

I will send it back as I am curious to see what they say...but if they want money to fix I will tell them to just keep it. Since shop is no longer carrying them I don't have the option of just returning it for an exchange...was good while it lasted.

FYI my room is closed but not sealed. I keep PPM's at about 1000 as any higher just takes too much propane. And of course it does not run when light are off. So runs every hour for a few minutes.

Mine turns on every 20 min or so as well. Seems about right to me

Do you have an issue with anything growing in the warm water? Seems like a perfect breeding ground for microbes. Would some bleach or chlorine in the water affect the pump or heater?

I throw pool shock in my chiller rez, or bleach. I think you have fewer issues if there's no light. My rez is for water cooled lights.

I have no light. It's in a garbage can with a lid in a dark room. I am concerned that something will grow as the water is getting very warm.

mine also runs for about 1 minutee every 20 or so, and i add 5 cups bleach to 50 gallons water, its been over 6 months and cant see anything growing in ti

How sealed are your rooms? I don't even have my door mounted yet, I have a heavy quilt nailed up over the opening, and I know there are leaks all over the place that haven't been sealed. I won't bother stressing over weather stripping and caulking every small crevice if a sealed room is running just as often as mine. I am running 1,500 watts currently. I am afraid my 35 gallon garbage in my basement is going to overheat too.

how's it going lf?

ey guy i run 3k in mine and a 55g barrel for the res thats about 5 feet from the lights, it gets pretty warm by the end of a light cycle but then cools right off by the next one. as far as being sealed my room is wraped w/ panda plastic every where but the ceiling so i think it should be pretty well sealed. as long as your not pulling air out of your room other air wont come in, to much
