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

Incognito.. and anyone else that is going to use this system. THIS IS THE PUMP!!

Fucking works awesome. Puts out massive pressure (the garden hose is rock hard when it turns on), it is completely self priming, and has just the right amount of flow. I actually had to turn the flow rate on the water heater as high as it would go! The heater is putting out considerately less heat now that the water is flowing so quickly.

thanx lf....bookmarked...just began grow room construction

So after finding out that many a commercial "water cooled co2 generators" were simply on demand tankless water heaters, I picked up a small one on e-bay.

Ran the NG lines to the grow room, buried a 50 gallon barrel in the ground , threw a sump pump in it, ran the hoses, and connected the water pump to my co2 controller. Tadahhh.. works like a charm!!

List of equipment and cost:
6 liter tankless NG water heater $165
harbor freight 1/2 HP submersible pump $40
50' length of heavy duty rubber garden hose $40
50 gallon plastic barrel = free
About 25'of NG pipe and misc fittings $60
never ever ever half to fill up another Co2 or propane tank and produce co2 at a FRACTION of the cost ... Priceless.

(I should note that if I bought the $375 hydrogen unit I would have needed all the stuff above anyways)

ok, I know the gasline looks kludgy at an angle but I won't risk running into it if I come into the room when its dark. The two other pictures show the routing of the water hoses around the room and out a vent to the barrel outside.

At first I cranked the unit up using both burners and maximum burn. The unit shut off at 1500 and then levels promptly kept rising to 2200. So I reduced the level and shut off one of the burners using the "summer time" setting. The Co2 turns on the water pump at 1425, the burner instantly clicks on, runs for about 4 minutes and shuts off at 1525. Levels then rise to about 1700. I put that fan on the ceiling to route co2 towards the controller on the other end of the room.

The unit barely puts off any heat. I would say its equal to a stove on the lowest simmer setting or about 5 big candles.

Just thought I would pass it on. Works like a charm.

Oh what the hell, whats a grow room photo without some god damned bud.... mid 6th week here.

Ok, I'm sold but not sure which one to get. Thinking Marey, Eccotemp, or other? I have propane
that fuels the gas needs of the house so I'll probably just tap into that and be done. Anyone have
suggestions for specific models?

Thanks,

I would just go with the cheapest one. The one I referenced on eBay has worked great once I had the proper pump. Mine is. 6l unit and i use it on the lowest setting.

The seller on ebu has been cool. The diaphragm ripped on me and he sent one the next day for free.

legallyflying would you mind posting a link to the heater you bought? i see the link to the pump but i didnt see the heater link. im not too lazy to find just getting cross eyed looking lol thanks...

 

[legallyflying]

I have the active aquah 6L. Depends on if your going to run NG or propane. I would suggest getting one with three knobs on the front. The knob in the center is a burner control knob for summer or winter. The summer setting only uses one of the three rows of burners, the winter uses all three. For my 12x7x7 room the summer settings is the best compromise between how long it is burning and how much overshoot there is.

Any will work but I think the three knob ones offer more flexibility and fine tuning

My little giant pump shit out on me. I set the system up on the 2nd floor now with my original pump. Hopefully it works (seems to be for the moment ... for the tenth time). I am going to try and return the little giant pump. 6 weeks of use is unacceptable.

Those are supposed to be good pumps. Weird that it blew put so fast. One word of advice however is that it appears that that pump works with an impeller. In general impeller pumps do not generate nor like being used at high pressures. The water heater, by the nature of the beast, needs a relatively high pressure.

The pump I linked above is a diaphragm pump. It generates ALLOT of pressure. I mean allot. When it's running the garden hose is rock solid. Check out that pump if you don't get a replacement. It would work awesome in the basement.

The specs and features on the little giant pump were designed to operated under exactly those conditions, I don't know why it failed. I set up the system on my second floor just outside of the grow room using the original pump I bought. If that shits out I guess I will move onto the third pump.

I think my pump shit out on me. For the last week the heater hasn't been kicking on. The pump has been running, but the co2 is ambient and the heater isn't on. Turning the heater off then on, or unplugging then plugging the pump in would kick it back on. Now the heater won't start at all. The ignition just fires continuously. I'm going to hook it up to the city supply to see if the heater still works, and if so I guess get yet another pump.

My water in my drums isn't the cleanest. When I had that happen I put the inlet house on the outlet and flushed the heater. Worked fine after that. Man, you have had the worst luck with the pumps!

 

[907]

You need circulate some vinegar through it, will clean it right out.

 

[guy incognito]

Well im a super dumb ass. With my great detective skills I managed to find the problem - nearly dead batteries. I am back up and running for the past few days.

 

[legallyflying]

Lol. It happens.

thought i should add to this thread i just ordered my second tankless for my indoor greenhouse!! than ks for the tip this trick is the bomb!!!

Ok now I've done a ton of reading about using a water heater for co2 gen. I am looking at either the marey 5l or the eco temp. Im going to use propane to run it. hopefully one of you two guys who have been posting can answer:

1. If using on a recirculating system w/ res, can you use the water in the res for your plants? Is it clean?

2. If using for drain to waste, I understand you have to get the valve to have hooked up to a sink, but I don't get it, does the water have to be turned on at all times into the valve? Because if you turn it off..and the co2 needs to come on, but can't get water..won't work right..

3. How do you hook up a co2 monitor to one of these? Prob getting the ppm4 model.

 

[legallyflying]

I would go with which ever model has a longer warranty.

In a recirc system you COULD use the water...but you would just have to fill it back up do why bother. The water in my drums has a bunch of zone in them to keep them clean. Pool chlorine would be cheaper and just effective.

Your pump in the rez (i highly recommend the pump i linked to) just plugs into the ppm controller.

If your going to use a drain to wasts system (you will burn in hell for
Wasting that much water, and your water bill will skyrocket )(easily 200-300 gallons a night), but you will need to install a 110 volt solenoid valve in your water line. That would plug into your ppm controller.

Solenoid opens, water rushes in...burner turns on.

You will be dreading the install but when you first turn it on....it's soo money.
