When 2.5 Gallons Is Not Enough

The 2.5-gallon mini-tanks dominate the category page because they are compact and inexpensive. But they have a real ceiling: once the tank is depleted, you wait roughly 25 minutes for recovery. For a low-traffic single-fixture install -- a bathroom sink that sees two or three uses per day -- that is never a problem. For a kitchen sink that runs continuously through meal prep and cleanup, or a utility room sink shared between laundry and workshop use, the 2.5-gallon runs out mid-task.

The ME60 solves this with 6 gallons. It is not a whole-house solution -- nothing in the point-of-use 120V category is -- but it extends the no-interruption window significantly.

Installation Notes

The ME60 mounts wall or floor with the included hardware. The cold inlet connects at the bottom and hot outlet at the top in wall-mount configuration. Standard 1/2" connections mean any plumber or experienced DIYer can complete the install in an afternoon. The 120V cord plugs into a standard outlet -- no dedicated circuit, no electrical panel work.

One practical note: the 6-gallon tank is noticeably heavier than a 2.5-gallon unit when full. Wall-mount into studs or use appropriate wall anchors for the installed weight. The manual specifies mounting requirements clearly.

Pros and Cons

Pros

  • Solid feedback from the largest buyer base in this comparison
  • 6-gallon capacity significantly reduces recovery interruptions vs 2.5-gallon tanks
  • UL Listed -- meets standard safety certification requirements
  • Wall or floor mounting gives genuine installation flexibility
  • Standard 120V -- no dedicated circuit or electrician required

Cons

  • Larger physical footprint than 2.5-gallon units -- measure the install space
  • Feedback is solid but trails the Stiebel Eltron's
  • Recovery time at 1440W is moderate -- not instant like a tankless unit

Bottom Line

CAMPLUX ME60 is a Buy. With solid feedback from the largest buyer base in this comparison, it is the most validated mini-tank water heater here for buyers who need 6 gallons of capacity. Not as premium as the Stiebel Eltron, but meaningfully better sized for high-demand single-point applications.
