Our verdict

A small point-of-use tankless heater for a commercial hand sink on a dedicated circuit. Its low flow rate suits a single tap, not a shower or kitchen.

Overview

Facility managers fitting a hand sink get a compact under-sink tankless heater that warms water as it flows. It mounts on the wall indoors and runs on a dedicated commercial voltage circuit.

Point-of-use heating removes the wait for hot water at a remote sink. The small body tucks under a counter. Low flow limits it to one tap.

Who it's for

Restrooms and break rooms in commercial buildings with matching electrical service suit it. Residential kitchens and showers need more flow.

Pros and cons

Pros
  • Hot water at the tap
  • Compact under-sink mount
  • No tank standby loss
  • High listed pressure limit
Cons
  • Very low flow rate
  • Needs a 208 volt circuit
  • Capacity spec looks wrong for tankless

Performance notes

Temperature rise depends on flow, so the low flow setting is what lets it reach usable heat. Incoming water temperature changes output in winter. Electrical supply must handle the full load.
