EcoPlus Commercial Grade Water Chiller, Cooler for Reservoirs, Hydroponics, and Aquariums, 1 ½ HP

I bought a Plunge Pro which has a rebranded Active Aqua AACH100HP. The Active Aqua is LOUD, specifically the compressor. It's about 68dBa, louder than low flying planes, loud enough to be heard by my next-door neighbors, and loud enough I could hear it all throughout the house. The EcoPlus 1 1/2hp was a direct replacement.. no adapters or pipe fittings needed. I just added the included rubber grommets to the Plunge connectors, screwed everything in and started it up. The noise from the EcoPlus is about 55-58dBa, which is silent compared to the active aqua. Most of that noise is coming from the fan, not the compressor. This means there's very little that is high pitched and I can barely hear it anywhere. Also, this thing performs incredibly well. The Plunge Pro cools down in a fraction of the time. The active aqua took about 1 hr when kicking on in the AM. The EcoPlus took less time than writing this review.

I bought this for a DIY 300 gal cold plunge. It is an absolute workhorse. It is extremely quiet and efficient. The water pump I use with it is louder than the chiller. In 100F degree weather, I can fill the tank with a water hose and it will chill the water to 38F in less than four hours. I've also used it in -10F and even though all the pipes froze, it has freeze protection and keep the unit's internal temperature above 33F. I will say that when it was delivered the box was pretty beat up but nothing was scratched or broken. I've had zero problems and absolutely love it.

After less than a year a connection inside the control board burnt up. The company re-directs the 800 number calls to Hawthorne GC and that company does not return calls or emails. I am willing to buy the new part if necessary. Not even looking for a warranty-type replacement (though I deserve it).

We’ve had this unit for 10mo now (bought Feb 2024) and could be more pleased! I was esp surprised at how well this unit performed this past summer with record breaking temps and nearly 6months of 100+ deg days here in Phoenix. We run this unit minimum5 days per week, yr round, turn it on at night, use it in the morning, and stays off while at work. Needless to say we have gotten tremendous use out of it in a short amount of time. It also drops the water temp in our ~85gal full makeshift cold tub-trash can by approx 10deg per hr. Decrease water, increase water chilling time. I also followed David Maus Jr for the set up and his Amazon products list for set up. He made everything very straight forward and easy! Highly recommend this product!

I have a 225 gallon 2 person hot tub I've converted into a cold plunge for the summer using this chiller. This is definitely a commercial grade workhorse chiller and has been working great even in 100+ degree Phoenix, AZ weather running 24/7 (it automatically kicks on when the water temp reaches about 3 degrees above the set temp). It is large but I appreciate the narrow/wide footprint as I have it between the spa and the wall. I currently have it set to 47F but it can go as low as 36F. Pump is sold separately. It's relatively quiet. You definitely hear it when it initially kicks on but then its just the hum of the large fan which isn't bad. No regrets, I would definitely buy this again.

We have the 1.5hp model. We use it to cool an 8x8 hot tub for summer. Our tub has 490 gallons. In the hottest months it does take a little while to get the temp in the whole tub to start coming down. I’d say when outside temps are at 100 or more, it would cool our tub about 3degrees per hour. Putting the unit in the shade defiantly helps. When temps are in the low 90s it cools much faster more like 5-7 degrees per hour. We didn’t keep ours on all the time, although you could leave it on and the cooler will cycle to maintain your desired temp. It does pull 1300 watts through a 110 outlet, the lights inside on that circuit noticeably dim when it cycles to start cooling. I read some reviews that the fittings are not standard and I’ll agree with that they are defiantly not standard, I did break one off. They can be found in the internet, and a fitting kit is not that expensive I bought 2 additional kits in case I need another.

The chiller works very well, however, it has just stopped working and shut off and the power will not come on at all. Had an electrician take the unit apart and look for the fuse and he could not find it. Does anyone have the number to the manufacturer to contact for replacement or repair?

Do not purchase!!!! If you did, be very careful!!!!! Unit caught fire after 5 months of use. I purchased Amazon’s warranty, but I have to go. Through Hawthorne. They are impossible to deal with. The phone number tells you to go to a website. The website says you have to be a retailer. I don’t have a good feeling about this company.
