ThermoMate ET060 6 kW Electric Tankless Water Heater

The ThermoMate ET060 is a compact electric tankless water heater intended for point-of-use hot water at a sink. Its listed 240-volt, 6,000-watt configuration and hardwired installation requirements make electrical capacity an important fit check before buying.

At a glance

Designed to heat water near a sink or other point of use rather than serving as a whole-home multi-point heater.
Self-modulating operation is described as adjusting energy use to the heating demand.
Touch controls and a digital display provide temperature adjustment in 1° increments.
The listing specifies hardwired 240-volt installation, a 30A circuit breaker and at least 10AWG wire.

Pros and cons

Pros

Compact dimensions suit installations where under-sink space is limited.
The listed 1.07 gpm flow and 35°F rise claim are geared toward modest point-of-use demand.
Temperature display and fine adjustment give users direct control over the setpoint.

Cons

The 240-volt hardwired connection and specified circuit and wire requirements limit suitability for plug-in or low-capacity electrical setups.
The listed flow is intended for a sink-scale application, not an assurance of high-volume or multiple-outlet hot water.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the title and features describe a 6 kW heater, while the detail table lists a 1-gallon capacity, which is not explained for this tankless unit. Dimensions also differ between the table's 7.5"W x 11.2"H and the feature text's 10.96" x 7.4" x 2.52". The flow is listed as 1.07 gpm in details but described as 1.0 GPM at a 35°F rise in features. Confirm the exact unit dimensions and flow specification for the selected listing. The manufacturer claims ETL listing in the title, but certification details are not provided here.

Customer feedback describes positive experiences with performance and quality, including a report of trouble-free operation for over two weeks. That is encouraging for buyers considering point-of-use use, but it does not establish long-term reliability or confirm the listed flow, efficiency or installation claims. Ratings skew toward the positive, while a smaller share are lower, so experiences are not uniformly positive.

Positive themes

Customer feedback mentions performance and product quality positively.

Frequently asked questions

What electrical setup does the ET060 require?

The listing specifies 240 volts, hardwiring, a 30A circuit breaker and minimum 10AWG wire. Confirm the circuit and wiring are appropriate before installation.

Is this intended for whole-home hot water?

The product is presented as a point-of-use heater for sinks. Its listed flow rate is modest, so it should not be assumed to support multiple outlets or whole-home demand.

How much space does it need?

The detail table gives dimensions of 7.5"W x 11.2"H and a depth of 2.52 inches, but the feature text gives different width and height figures. Verify the installation dimensions before purchase.
