  • Our take on the Tankless Electric On Demand Hot Water Heater - 120V | 4.5kW

    This is a point-of-use tankless water heater that runs on 120V and delivers up to 4.5kW of heating to a single sink or faucet. It heats water on demand with a self-modulating element rated 99.8% efficient, and the cast aluminum element sits outside the water line to limit scale and mineral buildup. The touch panel sets temperature in 1° steps from 85°F to 131°F, and the compact housing fits under or over a cabinet. It suits a bathroom sink, bar, salon station or reception desk where a short run of hot water is enough; it cannot supply a shower or a whole house, and flow is limited to about 1.0 GPM.

    About the Tankless Electric On Demand Hot Water Heater - 120V | 4.5kW

    This is a tankless electric water heater that supplies hot water on demand at the point of use, such as under or over a sink faucet. Its 4.5 kW heating system heats water in seconds. It regulates the energy it uses and only heats water when you need it, with 99.8% efficiency.

    The heating element is cast aluminum and is separated from the water line, which significantly reduces scale, corrosion and mineral buildup. The water tube is SUS 304 stainless steel.

    The compact body fits in tight places such as under cabinets and sinks, hair salons, bar counters and hotel receptions. A touch control panel and digital display let you adjust the temperature in 1° increments. Installation uses a standard 1/2" NPT pipe fitting and a pre-wired pigtail.

    Questions and answers

    Can this heater run a shower?
    No. At 120V and 4.5kW it heats about 1.0 GPM, which is enough for a single sink but not a shower or tub.
    Does it need a special circuit?
    It is hardwired at 110-120V with a pre-wired pigtail, so it needs a dedicated circuit sized for 4.5kW. It does not come with a plug.
    How hot can the water get?
    The range is 85°F to 131°F, adjustable in 1° steps on the touch panel.
    Will it fit under a bathroom sink?
    At 10.95" x 7.4" x 2.52" it is built for under-cabinet and over-sink mounting in tight spaces.
    Does it scale up like a tank heater?
    The cast aluminum element is separated from the water line and the tube is 304 stainless steel, which the maker says reduces scale and corrosion.
    What fittings does it use?
    Standard 1/2" NPT pipe fittings, and the unit is IP25 water resistant.
