I’ve been using this 1.6-gallon mini tank water heater specifically to bring water up to temperature for my aquariums during water changes, and it has made a huge difference in my routine. Before, I had to mix hot and cold water manually and constantly check temperatures to make sure I didn’t stress my fish. With this unit, I can get water up to the right temperature quickly and consistently. It heats up fast and maintains a stable temperature, which takes a lot of the guesswork out of the process. The size is perfect for my needs—it’s compact but still provides enough hot water to prep buckets efficiently. What really stands out is how much time and effort it saves. Water changes used to feel like a chore, but now the process is smoother, faster, and far less stressful. Overall, it’s an efficient and reliable little heater that’s made aquarium maintenance much easier. I’d definitely recommend it to anyone looking for a simple way to get on-demand, temperature-ready water.

Arrival took a day or two longer than expected, but it arrived well packaged and included simple directions. I set this unit up outdoors on my game cleaning station. (Must be taken down during freezing temperatures) The heater is simple to install. I am running it without issue on a 110 V plug with 10-2 wire and a 20amp breaker. I did add a pressure regulator due to my high-water pressure on my outside assemblies. Unit heats fast and works better than advertised. It takes 1/2-inch hose connections which work well with PVC male fittings. I built a backboard on my sink cabinet to hang the unit. It does tend to "lean" forward a bit but is steady, even with a full tank of water. So far, I truly like this set up.

This Mini Tank is working out very well. We're saving a lot of money bc prior to installing this Tank,we were loosing a lot of water when we needed hot water bc when we turned on the hot water handle it would take over two gallons to even get hot water. So now it takes 2 ounces to have hot water.

We just purchased a new house and its in Alabama and the foundation is a cement slab, and all of the water lines run under the floor. We usually have to run the water in the kitchen sink for what feels like ten minutes just to get hot water, and during the winter its even worse! So I thought I would pick this up and install in under the sink, what a great decision! Since the unit comes with a 110 plug, I just use the outlet that was already under the sink for the disposal and plugged the tank in there. I split the hot water line that ran to the faucet, ran that to the tank, and out of the tank back to the faucet, easy as pie! And the wife is thrilled! You know what they say, happy wife Happy life!

Water heater is 2" deeper then the dimensions listed. I ordered it to fit in a specific place, and it will not fit. I've had to order another, and am stuck with this as the packaging got damaged.
