Immersion Water Heater 1800W 120V with Digital Thermostat Control, Dry Burn Protection Alarm, Real-Time Temperature Display, 14AWG Heavy-Duty Cord, Industrial Heating Tube for Buckets & Bathtubs

Why we love it
  • Precise thermostat control.
  • Dry burn protection ensures safety.
  • Industrial-grade 1800W heating.
Main Highlights
  • SMART DIGITAL THERMOSTAT CONTROL: Built-in temperature sensor and digital controller allow you to set your desired water temperature up to 175°F. This immersion water heater with thermostat pauses at the set point and reheats after a 15°F cycle to maintain stable heating performance. Ideal as a bucket water heater, bathtub heater, or controlled-use portable immersion heater.
  • DRY BURN PROTECTION WITH AUDIBLE ALARM: Engineered with advanced dry burn protection, this submersible water heater will NOT operate unless the heating tube is fully submerged. If the water level drops, the unit automatically shuts off and activates an audible alarm. This helps prevent heater damage, overheating, and premature failure caused by dry firing — one of the most common causes of immersion heater burnout.
  • INDUSTRIAL-GRADE HEATING TUBE – 1800W POWER: Powered by an industrial-grade stainless steel heating element designed for long-duration operation. Delivers efficient 1800W heating on standard 120V circuits. Built stronger than typical portable immersion water heaters for improved durability and extended service life in buckets, bathtubs, and controlled small-tank applications.
