I have been dealing with this product for about a month. I bought two of these pieces of garbage. I'm out about $3000.00 and a ton of work. Let me detail some problems:
1) Co2 computers will not fire the sump pumps, they are only rated for 1/2 amp for a solenoid.. I had to go to radio Shack, buy a transformer, take out the HydroGen battery pack, and have the computer turn the burner on and off ( which it does not do reliably) and let the pumps run 24/7 ( hello burnt out pumps).
2) The inlet screen for the water is tiny, the smallest particles will clog it resulting in poor water flow, then the burner shuts down.
3) Unless you have tons of space, where will you put a couple hundred gallon reservoir and chiller? So I used Hydroinnovations (H.I.) suggestion and did a open air tank outside. 725 gallons. Which of course gets debris ( see 2), after some clever filtration ( totally clean now), still can't get it to work.
4) After calling for tech support I was told to readjust the sensors ( take the burner apart) take off the gas flow regulators, and circumvent the battery pack. I also have used six different types of pumps at H.I. suggestions.
5) if you do drain to waste be prepared for a water consumption around 1000 gallons a day. How friendly are you with your water department? You do drain to waste and your gonna get much friendlier.
Here's my thought, this is a product that was rushed out and is WORTHLESS!!! At best it is so tempermental ( water flow, gas flow, batteries, etc.) that it is useless to use. It is obviously not ready for use. Wait a few years, if they are still in business post your question again.
I have spent over a month fiddling with these, I have spent thousands beyond the burner cost ( pumps, ponds, chillers, computers, numerous fittings), have done the Home Depot run about a dozen frustrating times, had several conversations with H.I. and they still DO NOT WORK!! I am now to far into my cycle to recoup anything ( assuming I can ever get this to work)
I am in the process of trying to get a refund ( or as much as I can ) from the store I bought them at and scrap this idiocy. I also plan on contacting the Hydrofarm rep and letting him know what I think about being ripped off.
If I could get it to operate for longer then 90 seconds I would be overjoyed. I'm not overjoyed, do the math.
