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

I have the same issue with my heater. it kept being a pain in the arse so I just ordered a new one. You might want to flush it with a 3 to 1 solution of CLR which is just a pipe decalcifier you can buy pretty much anywhere. 3 parts water, 1 of CLR.

Its possible that your pipes are getting clogged up. your suppose to flush tankless heaters once a year.
 
Hello Everyone, First post on the Forum and first time grower, long time forum researcher though. I read through this entire thread and many others, I can't seem to get enough, great info.

My first question is to legallyflying (or anyone else), can you illustrate your new pump setup. From what I gather, it is outside the rez, pulls water in with 1/2" hose (is this hose coming from the top of the rez or bottom) and then pumps out using another hose to the AQUAH. And the pump is plugged into your CO2 monitor which turns the pump on and off as needed?

The AQUAH is battery powered right, so it turns on when water flows through it?

Buying a 55 gallon drum, hoses and I think the CAP fuzzy monitor today. With an AQUAH heater soon after. I just don't know what pump to use, or rather how to use the one you suggested.

Thanks.

Damiana
 
High pressure low volume pump. Yes from the barrel to heater and back to barrel. Any think of the rand of pump right now but there is a link above.
 
Glad to see this post still alive after all this time. I've had now in 2 years 3 diaphrams go bad in my cheapo water heaters. I did send 1 back for repair mainly because I wanted to know what kept happening. I think its just a flaw in these because they aren't actually meant to be full time water heaters really. I did recently upgrade to a $300 model of heater that actually has digital temp read out, and AC power and seems to be running well and made better quality. I guess it will need to last twice as long to make it worth while, time will tell. It definitely does the job way quicker however, pumping up my CO2 levels much faster, not sure if that is good or bad.
 
The faster it reaches, the more overshoot your going to have. Other than that, not really an issue.

Glad it's working well. I got pissed at my cheese dick water heater and bought a marey. Not sure what I did but the cheese dick is still going strong. Marry been sitting in the box for weeks
 
Sub'd for this, and all future discussion it - hell of an idea, and am sure that the savings are phenomenal :D

Once you buy the gear, the co2 is essentially free. (At least when burning NG)

Have NG for furnace and hot water heater.. and there's really no way you can justify not getting one of these if you grow more than a small room... I'm really diggin' it, and was trying to figure out ways I'd have to explain to the wife as to why the welding supply truck would keep pulling up. This does the job, and saves cash. After quarantine room is done being constructed, am going to pick up the goodies and get this ball movin' :D
 
Just as an FYI. The barrels of water really need to go outside. I recently moved my stuff and have the barrels downstairs. While they do put off a good amount of hear and keep the basement warm, they have to be covered or it's like a jungle down there. They radiate heat for sure.

Also. Make sure you get the shure way pump and run a small pressure release T. You may not need one if you have a big heater but the pump is rated higher than 6 or 8 lpm and that flow difference builds pressure. Which makes the pump work harder, which an burn out the brushes. Other than that, it's really straight forward

Also, the gas line sealer you brush on is much easier than the yellow Teflon take
 
I use a 55 gallon barrel directly on concrete and the water stays below room temperature. I'm running 2400 watts total lights. The pump only kicks on every our or so with a moderate amount of overshoot.

Noted, 2-3ft underground to avoid freezing, and overheating? I'm in a climate that can go from 80-90F summers to 20F-ish below in winter.
 
Yeah that's weird. Mine runs probably every 15 minutes or so. Could have leaks somewhere..I mean I do have 14 AC hoods in there. That is a lot of chances for leaks. Either way, I can't hold my hand in the water during veg. It's probably 120

Oh yeah. It's shureflo not shure way

You may just have a lot more plants than I do if you have 14 AC hoods. I'm only running 3 totaling 2400 watts.

I have been chilling in here for about 1.5 hours. Smoked a joint. The ppm actually increased a few hundred ppm.
 
My shureflo pumps appears to be dead. No sound or anything when it's plugged in now. My heater is only about 3 feet from the barrel, and only about 3 feet above it, so I think i'm just going to purchase a cheap submersible pump. Every pump I buy seems to have a very short life regardless of the type of pump or the price. I think I will just budget in $25 every 6 months to buy another cheap pump.
 
Yes I did. I ended up having to partially close the valve after the heater stopped firing though. Slightly closing it caused enough pressure build up to ignite the heater again.

There is no hum or anything when the pump is plugged in.
 
They don't sell brushes. But I had the brushes wear all the way out on one unit. I tried to order similar sized brushes on eBay but they didn't match. If you call them they will replace it for free, no questions asked.
 
Oh yeah..almost forgot. My buddy has what might be the perfect pump. I will post a link later but they are SUPER heavy duty and very quiet pumps designed to run hydronic heating systems. So low flo and high pressure. My buddy has a couple in his hydronic ally heated home..it's 6 years old and has run pretty much continuously
