  • Works great !
Style: 6.0Gal
This is the second CAMPLUX hot water heater I have purchased. I use this in a tiny house and the last one lasted for 7 years without a problem or concern. It provides plenty of hot water, takes up minimal space , and is easy to hook up.

  • Love these mini-tank heaters.
Style: 1.3Gal
To be sure we get instant hot water, I put a mini-tank under every sink in the house about 8 or 9 years ago. We love them and would never do without them again. Best and most cost effective way to get really instant hot water for hand washing, dishes, laundry sink. Only problem is they only last about 6 years or so, so you have to replace them. After about 6 years they begin to leak very slowly underneath. I installed mine sitting in cheap plastic storage tubs under each sink. Use a $10 water alarm in the tub to get early warning of a leak. You have to buy a size and brand that has shape and dimensions to fit under your sink and drain pipes, so plan carefully. I have several different brands and they all leak eventually. But for 6 years you get wonderful warm or hot water to wash your hands in without waiting forever. I've had this exact heater before (except a different brand name) and it has worked very well. Each heater only adds a dollar or two per month to your electric bill. ... show more

  • Works well, but draining is paining
Style: 2.5Gal
This is a nice compact electric water heater. It heat water nicely -- I have it set to a little below the 125 (Fahrenheit) setting since 125 degrees is pretty hot for washing hands. Plumbing it requires getting your own hardware at Ace, Home Depot, Lowe's, et cetera. It comes with the pressure relief valve, which you also need to install. The main drawback is that the only way to drain the heater is to disconnect its plumbing, unmount it, take it somewhere, then turn it upside down to pour the water out. Not particularly convenient. A lesser drawback is that if it happens to fall a few inches, it will start to drip-drip-drip leak out the bottom - presumably the glass shell inside cracked. This happened to us, and so this purchase was a replacement. Our use is in a campervan, and the heater is mounted over a tub to catch any water if there is a leak. The only leak happened when we bounced over a big rut, and the heater fell into the tub - which is why the replacement. I mounted the new unit more securely, and hope this one lasts at least as long as the first one (4 years). ... show more

  • Great company!
Style: 4.0Gal
Camplux is a good little water heater; I had a plumber put the 4-gallon water heater under a sink; it worked beautifully for a bit, but then it started to leak under the tank itself. I called the plumber, and we realized it was leaking from within. I contacted the company about it, and they were very professional. They took care of my problem quickly and sent out a new one to replace it. It was NOT their fault or my plumber's fault. It happens sometimes; who knows how or why it happen, but again, they were quick to solve my problem. That shows you how Camplux is a great company that stands behind its products. I would buy from them again, and y'all should, too. ... show more

  • Shower Usage
Style: 4.0Gal
Passed my expectations! I bought this to use for 3min navy showers in case of emergency. At first all we were getting was a couple minutes of usable hot water. But after installing a thermostatic valve and set at a comfortable 105degrees i tested for at least 10 min and no sign of the water getting cold. I used Oakley Grey tape 4 wraps minimum to seal all my threads. Not one leak. I set it up for testing purposes only before installing it like it's supposed to. ... show more

  • Works well. Very convenient, but . . . .

Works well. Very convenient. The only thing I didn't like was that the company did not sell replacement elements, and they wouldn't tell me the specs so I could order one elsewhere.

It's working well so far. Hooked up 2 weeks ago and it's giving me hot water. I wash dogs with it all day long. Hubby says it wasn't hard to install. No leaks
