These units are customer returns.  
They have been inspected and tested by the Technical Support at Marey and deemed to be refurbished.

What does this actually mean?

The customer set-up did not work with this unit and they returned it.  Nothing wrong with the unit.  Sometimes things just don't work out. 

What else does this mean?

You can pick up the "like new " unit for a nice discount on the price.
The only thing you lose is some of the out of pocket expense.

These Refurbished units carry the same Marey 5 year warranty. 


Marey Refurbished 6 Gallon Point of Use Mini Tank


Enjoy the convenience of hot water with just the turn of a faucet!

Best Electric Mini Tank Point of Use Water Heater.  Saves water; avoid wasting water down the drain while waiting for hot water to reach the faucet.

An excellent choice for Single Point of Use applications. The Mini Tank 23L Marey Point of Use 6 Gallons water heater is great for Buffets, Basement Wet Bar, Bathrooms, Kitchen, RVs, Boats Food Trucks, Hair Salons, and many more locations.

Perfect for remote places or places at home far from the tankless heater installation;  it requires a 20 Amp Breaker and 110/120 volt standard 3 prong wall plug receptacle.

The TANK23L unit is ETL certified and it has a knob control for temperature settings.

This unit has a 6-gallon capacity so it is great under sinks for quick uses and can also help to avoid the lost gallons of water that are wasted while waiting for the cold water to pass through the pipes until the hot water from your water heater reaches you desired point of use.


The smartest instantly hot water solution.

  • Heat only the water needed for the start of your shower (23 liters) while your tankless water heater will provide later unlimited hot water = do not waste water while you wait!
  • Save water: avoid running water down the drain waiting for hot water. Perfect for the “under the sink” concept in cold places that requires instant hot water for one or two simultaneous points of use.
  • Saves space.
  • 5-year warranty.

Also consider if you are using the braided stainless steel hoses, you will have a radius turn above the unit that would bring the needed clearance to about 22" or more. This can be offset with 90° elbows (1/2" FPT to a 1/2" MPT) for the water lines. 


Easy to install, all you do is hook up the water lines, check for leaks and plug into a standard 110/120 volt grounded wall jack.
