Thanks Bob Do you know if those hydrogen gens can be run on a closed loop with no chiller? does it matter how hot the water is? if its not in the room then who cares how hot the res gets..but just wondered if they would break down or something if i just continually pumped hot water through...

I have to agree Bob.. I am using the bottled co2 now and its a royal pain in the arse!! I scratched the whole using my house heater for co2 beacuse the exhaust coming out is piping hot and would defeat the whole puprose. So i am looking into the hydrogen co2 natural gas generator mounted...

A natural gas flame produces CO2. Water heater....gas heater...Gas Dryer....Gas stove....anything that burns propane or natural gas. The problem comes when oxygen runs out, the flame starts to burn CO2 (yellow flame) since there's not much left. Carbon Monoxide becomes the by-product from this...

LOL.. yea its a good thing nobody lives in there.. but will see if it pans out.. if not i guess ill have to buy an overpriced marketed co2 generator that does the exact same thing...LOL

Its natural gas.. it has an exhaust, a manual thermostat, and is supplied 120v power. In reality its a co2 generator on steroids..lol all i would need to do is hook a controller to the heater and tap into the exhaust to vent into the room with a duct booster. Set my controller to say 1700, set...

Thanks sage, but how do you know if its 80% or 95%? I did quite a bit of research on this and it really seems doable...check this article out. http://ezinearticles.com/?CO2-for-Free&id=48431

Thanks for the help 5hit, I will have an AC in the room but i see your point. Like i said i will be testing everything beforehand to make sure its feasible and efficient. Ive been reading the manual for the heater and it says it has a heat exchanger for the exhausted gasses, but how much heat...

Yea i think it will work..and like you i will never have to refill a tank again. lol I run my lights from 7pm to 7am here so temps stay pretty good. I will have to do some testing to make sure it works and is safe. One thing that worries me is if the heater is constantly firing up it might...

If im correct it wouldnt take but a minute or two to fill the room with heater exhausted co2. The ducting that transports the heat to each room run in the attic. I can pull those from the vents to the bedrooms etc and run them to the attic vents. Plus nobody lives in the house. I will have to...

Thats a 40 gallon panda res with 4 posts.. 1ft spacing between plants. 800gph pumps. Im trying to find the sweet spot of how many plants to run. Theres 16 holes, 4 per post. The tops were already harvested on the 16 plant blackberry unit on the left. The unit on the right has 13 plants. and...

Tat2ue, Ive been meaning to ask you, how warm is the air coming from your water heater into the room?

Why not? Its natural gas.. it has a flue, a manual thermostat, and is supplied 120v power. In reality its a co2 generator on steroids..lol all i would need to do is hook a controller to the heater and tap into the flue to vent into the room with a duct booster. Set my controller to say 1700...

Yea its a centrel house heater. I was thinking i could set the maual thermostat located on the heater itself to a temp that will enable it to fire up everytime power is provided through my co2 controller. sounds easy enough??

heres a couple pics of my new room... no c02 yet but im trying to figure out a way to use my natural gas centrel house heater in a closet right next to the room to supplement the grow room with co2 any ideas? heater below

Yo watercooled..check out my natural gas heater right next to my grow room. If i could figure out a way to utilize it it would be ideal dont you think? any ideas?

Glad its workin out great for you guys. I need to get mine setup somehow. I have a natural gas centrel house heater in a closet right next to my flower room. (PICTURE BELOW) The only problem is its never used ,,ever. But im trying to figure out a way to maybe run it at a low setting on a...

Yea arbah..i hear ya im pretty much over the watercooling headache Im thinking '" Isnt my gas heater just a big co2 generator?" Why not just keep the pilot light lit and divert the exhaust into the flower room using powered damper vents and my co2 controller? heres an article i found...

I know this is an old thread but i just wanted to see how your free co2 setups were going? I have a natural gas heater literally on the other side of my flower room wall calling my name.

Yea it does sound too good to be true. But if the hydrogen watercooled is the only unit that has a duct port, and needs water to run, and if its housed in a seperate room.. then would the water even need to be cooled.. ?? I imagine the reservoir water would get freakin hot,, but would that...

Ive been researching about c02 generators and i cant get an answer... Is there only certain models that are capable of ducting co2? And if so what would you recommend? My room is just about 1500 cubic feet. I have a natural gas heater in a closet with the gas line and valve (not being used)...
