Features

  • Note: This model C3000 (3kW 120V) mini tankless water heater is designed for low-flow use only, not suitable for showers or multiple taps at once. The output water temperature is affected by many factors, including the water heater wattage (heating capacity), inlet water temperature and water flow. For a better warm water use experience, we recommend that you consider our higher wattage model 6.5kW 240V first, which is hard-wired
  • Easy to Use: Large LED digital display with big control knob, this point of use water heater 120V is very easy to use. 1 knob for power ON/OFF and temperature adjustment, offering a better use experience than others 3 little touchscreen buttons. You can adjust the temperature between 30C and 55C
  • Multiple Safety Features and Intelligent Design: Every Lecloc water heater is rigorously tested to ensure reliable performance. This instant water heater is engineered with comprehensive safety protections, including leakage protection, overheat protection, dry combustion protection, high water pressure protection, IPX4 waterproof and is drop-test passed. Plus, it has functions of automatic fault diagnosis and constant temperature memory. Very safe and smart to use
  • Efficient: This 3kW 120V on demand water heater under sink is suitable for 1 point of use. It can provide 24-hour endless warm water without the need for preheating, saving much compared to tank water heaters
  • Widely Applicable: Whether you need warm water for a sink in kitchen, bathroom, laundry, basement, offices, shop, apartment, dormitory, garage, bar, or hair salon, this small point of use water heater has you covered.

  • Keeping the calcium at Bay!!
These are awesome, you should check your water heater every once month, and flush it, and will only use one of these a year, but this Brand is good so far!!

  • Protect your water heater
Your anode rod is a normal maintenance item. It is expected to deteriorate and needs to be replaced in two to five years. I always remove mine when I winterize my RV. That lets the water heater dry out for the winter and in the spring I replace the rod if needed. As near as I can tell this is the same thing I have been buying at the store except these come with gaskets (I still use Teflon tape anyway). You always need to have a spare. ... show more

  • A little long
When I got these, I didnt realize that you replaced the anode rod maybe once every 8-12 months. They've been sitting around for a while, but I finally got around to replacing this. I like that you get 2 of these bad boys, but they run on the long side. I had to look up how to videos (hence the deduction of a star) , but when I found what I had to do, it was easy and I used the tape that came with it. Water seems good so far. I'm a RVing newbie and if I can replace this, anyone can. ... show more

These are just as good as the anode rods I can purchase at my local camping store.

  • Anode Rod
I ordered this product to use on my shower room. It has a great quality. My favorite thing about this product is its length.
