absolutely no need for hot water
We probably couldn't sellnhim a bag of sand either! Seems that his only benifit would be to perhaps removing the heat from the room with a few less watts, but the extra initial cost of the build dosent seem to make sense in this situation, perhaps just a little nighttime temp control. Would be nice if threre were some other way to extract the heat energy from the hot water he dosn't need.OK. - think about - if you ever have to move to Canada
Sorry - in a water flooded world - that`s NOT a bad buisness idea.sellnhim a bag of sand
nooh --- it is incredibly cheaper - if you buy the same chips and driver -but the extra initial cost
... but health care is free, so why don't you go to the doctor and get your head checked?I live in a country where prices for energy are high
Just leave the numbers away if you're not able to calculate or understand physics.mahiluana said:I say: heat power = ~ 0.75 * If * Vf and I can recover 80% of this heat, whatever the brand or bin...even @ low current they all produce 70-80% heat.
I get what you're saying but he already has the other system in place, if going new or expanding then sure, but the equipment he has still owes him money.Sorry - in a water flooded world - that`s NOT a bad buisness idea.

the heatsink makes the difference.
for a watercooled build 5KW - i spent as low as 150$ - with a better cooling result.
10m of aluminium square tube, fittings, pumps and hose
a heatexchanger 800L is not cheap if you buy a new one.
a basic version works only with a huge water container (you can get for free)
with 5 waterpumpies (2,4w each) you can manage the heat.
So i see lower set-up and maintanance cost for a watercooled build.
i know, that my girl and i need ~ 30000L of hot water / year
and normally have to pay ~250$ for the hot water bill to the house owner.
so 2700000KW @Toohighmf of hot water in my town is worth ~ 360000,- US$
Now a 350w watercooled led lamp in my household produces 80L / day
and the savings on my hot water bill is 50% of the electricity bill that produces my lamp.
I`M NOT SCOTTISH - I live in a country where prices for energy are high
Sorry - my personal calculator smoked too much weed yesterday4.500.000KW and you could rewin 2.700.000KW of heat in the next 7 years
i know - but my posts are also an advice to everybodyhe already has the other system in place

It’s not just higher upfront costs. 19’-8”l x 9’-6”t x 7”-8w” isn’t a lot of room to produce and have to maintain in. Maybe I’m misunderstanding exactly what you water coolers are doing. Running a closed loop from a separate reservoir with a chiller, glycol & coil or radiator, (unless it’s freezing outside) and pump, no?
We were already considering using evaporative chillers for climate control, but I’d love to read more about how to use the existing system climate control to water cool these lights
Take this as an example only, here is basicaly what you describe as a typicall water cooling system.It’s not just higher upfront costs. 19’-8”l x 9’-6”t x 7”-8w” isn’t a lot of room to produce and have to maintain in.

The huge amount of heat energy they are able to sink is a result of theusing evaporative chillers
my definition of a typical watercooled set up - is a closed water loop in a square aluminium tube.what you describe as a typicall water cooling system.
...but also for your grow room.to store the heat and recover it when and where I need it
@ToohighmfThat dosent really work in your locale since the outside temps are so high.
another advantage of watercooled lamps -19’-8”l x 9’-6”t x 7”-8w” isn’t a lot of room
Ever have to? You mean get to! I can’t take it anymore!OK. - think about - if you ever have to move to Canada
with the heat power stored in a watertank its much easier`to keep the room cool during light cycle -withstand hi temps in the summer and freezing days of winter.
you can bring back the heat to your room during the night, as your lampbody is also a perfect radiator - temps. and humidity are easier to manage.how running a chiller large enough to cool roughly

Been talkin to torotoke have you? 8hr flower?That’s too funny! No I’m not growing on the 30th Parallel! I’m a Jew and American. Don’t think they’d like my passport...
I’m in SoCal, and the client is in the desert nearby. Peak heat is July-September and yes, it cools down pretty good at night to 95F! We want to build a room that can efficiently cool day or night. We will be blooming in 3 different 8 hour shifts so we need it to be able to withstand hi temps in the summer and freezing days of winter.
If im visualising and remembering properly, you still have ac units running to cool the area in addition to the 240w of fans running cool tubes? The only way it would work is if you no longer had to run the room ac, or dich the chiller (which dosent seem to be a viable option for you, but others like me that have to constanly add heat to the lower ambient temps a radiator works, no chiller needed.)Ps
I don’t understand how running a chiller large enough to cool roughly 16000 btus could EVER be as efficient as running 240w of in-line fans; both in up front costs or utilities.
That being said, Please share any diy wc links!
He's 95 F at night so he has to have a way to get below that, perhaphs could do it with something like am10,000 gallon under ground tank, but agiain he's in a desert so 10,000 gallons of water might be more valuabe than electricity to cool. @Toohighmf your location is making this difficult for us, would your client consider moving?with the heat power stored in a watertank its much easier`to keep the room cool during light cycle -
(you need less incoming air (and water) for your plants, less fan power and carbon filter.)
you can bring back the heat to your room during the night, as your lampbody is also a perfect radiator - temps. and humidity are easier to manage.

this was the cooling management of my first watercooled prototype (330W)
i had to add 4-5L of water / day to compense the evaporisation
and rise easiely air humidity to veg in the grow room.
(less)hot and dry incoming air in a hot summer desert day could be conditioned quickly and "free".
the cooling tower in my drawing above ^ is a simple U-pipe with a wet curtain inside and airflow,
and can suck out your btus as quick as your size of airflow and curtain(surface).
