The large one has a warranty . Listen sir, this is clearly not my first rodeo. I appreciate what you think to be help but you are the one that is confused . Right now I currently am running two 90 pint and two 70 pint in that room... 4 dehus.. = to 31 amps .... Running 24/7 .. This is equal to 6 1k lamps running 12/12 . My electricity bill is well over 3000 per month . If I can knock my bill down 200 bucks a month by using an industrial dehu and taking out a couple inefficient Walmart dehus.. Then the unit will have paid for itself within 1 year . Not to mention it puts off less heat , and takes us less room that 4 of the little ones. And it's less amps freeing up some of my breakers.
I had know way to know those details
nor would I know your grow is that size
and I wasn't suggesting this is your first rodeo
the heat and energy conservation are something I hadn't considered and I appreciate your explaining so that perhaps I can use that info in my future endeavors and something I should learn about or look into
apparently (for some reason) im irritating you with my worthless 2 cents and for that I apologize
if you said im running 15000 watts (or more)in light with 400 plants then it would have been more clear as to why you want an industrial unit
i don't think any part of what i had said was incorrect or untrue or unhelpful to others whom may come across this thread in search of info on dehumidifiers
either way i wont be bothering you again
peace
