Enjoy continuous hot water whenever you need it with theThermoMate 14kW Electric Tankless Water Heater. Designed for residential indoor use, this compact 240V water heater deliversup to 3.4 GPMwhile heating water only when a hot water fixture is opened.

Its intelligent self-modulating system automatically adjusts power output according to incoming water temperature and flow rate, helping provide stable hot water while reducing unnecessary energy consumption. The slim wall-mounted design is ideal for apartments, small homes, bathrooms, cabins, offices, and other spaces where floor space is limited.


Important Electrical Requirements

Please confirm that your electrical system meets the following requirements before purchasing:

  • Power supply:240V AC
  • Rated power:14kW
  • Maximum current draw:Approximately 58.3 amps
  • Required circuit breaker:One dedicated 60-amp double-pole breaker
  • Required wiring:6 AWG copper conductors
  • Recommended main panel capacity:At least 150 amps
  • Water connections:Standard 1/2-inch NPT

Professional installation is required.A licensed electrician should verify your home's available electrical capacity through a load calculation before installation. All electrical and plumbing work must comply with applicable national and local codes.


Continuous On-Demand Hot Water

The ThermoMate electric tankless water heater heats water as it flows through the unit, eliminating the need to store and repeatedly reheat a tank of water. It provides a continuous hot water supply without the recovery time associated with traditional tank water heaters.

With a maximum rated flow of up to3.4 gallons per minute, the unit can support one shower or selected combinations of a shower and low-flow sink, depending on inlet water temperature, desired outlet temperature, and fixture flow rates.

Intelligent Self-Modulating Control

The built-in self-modulating system continuously monitors incoming water temperature and flow rate. It then automatically adjusts power consumption to match the current hot water demand.

This intelligent operation helps maintain a more stable outlet temperature while avoiding unnecessary operation at maximum power during lower-flow applications.

Adjustable Touch Control

The responsive touch control provides convenient temperature adjustment from86°F to 131°F. The digital interface makes it easy to select and monitor your preferred hot water temperature.

Heavy-Duty Cast Aluminum Heating System

The heater is engineered with a durable cast aluminum heating block and iron-chromium-aluminum alloy heating elements. Its advanced water-and-electricity separation structure helps reduce direct contact between water and electrical heating components.

This design helps limit scale buildup and corrosion while supporting dependable long-term performance.

Energy-Efficient Tankless Operation

Unlike conventional storage tank water heaters that continuously maintain a tank of heated water, the ThermoMate unit activates only when hot water is requested.

By eliminating standby heat loss and adjusting power output according to actual demand, the system can help reduce unnecessary water heating energy consumption.

Compact Wall-Mounted Design

Measuring only11.2 inches wide, 15.9 inches high, and 3 inches deep, this slim electric tankless water heater installs directly on the wall and does not require floor space for a bulky storage tank.

Its modern gray housing fits neatly in utility rooms, apartment closets, bathrooms, cabins, office break rooms, and other compact indoor spaces.

ETL Listed with Multiple Safety Protections

The unit is ETL Listed for residential indoor use and incorporates multiple built-in safety features, including:

  • Electrical leakage protection
  • Over-temperature protection
  • Dry-heating protection
  • Surge and lightning protection

Each unit is factory tested before shipment to support dependable operation when properly installed and used according to the product manual.


Recommended Applications

  • One residential shower
  • Bathroom sink
  • Small apartment or condo
  • Small home or tiny home
  • Vacation cabin
  • Office break room
  • Utility room
  • Selected low-to-moderate demand commercial applications

Fixture capacity depends on your local groundwater temperature, desired outlet temperature, temperature rise, and combined fixture flow rate.

Important Sizing Information

The maximum 3.4 GPM rating is based on favorable inlet water temperature and temperature-rise conditions. Available hot water flow will decrease when a greater temperature rise is required.

Before purchasing, compare your local groundwater temperature, desired outlet temperature, and combined fixture flow rates. Homes in colder regions may require a higher-capacity electric tankless water heater to operate multiple fixtures simultaneously.


Professional Installation Required

This appliance must be hardwired and cannot be connected to a standard household electrical outlet. A licensed electrician and qualified plumbing professional should complete the installation.

Before installation, verify the electrical service capacity, panel load, circuit breaker size, wire gauge, grounding method, water pressure, and plumbing connections. Always follow the installation manual and all applicable national, state, and local codes.
