The Infinity AquaHeat Submersible Aquarium Heater is designed to maintain consistent water temperature one of the most critical factors in keeping your fish and corals healthy.

With adjustable temperature control and built in safety features, this heater provides reliable performance for both freshwater and saltwater aquariums.


Why Temperature Control Matters

Sudden temperature changes can:

  • Stress fish
  • Damage corals
  • Lead to illness or loss

A stable heater keeps your tank consistent and safe


Precision Heating System

  • Adjustable Temperature Dial
    Easily set your desired temperature
  • Automatic Thermostat Control
    Maintains consistent heat without constant adjustment
  • Even Heat Distribution
    Works best when placed near water flow for stability

Proper placement improves heat circulation and consistency


Built In Safety Features

  • Shatter Resistant Glass / Quartz Construction
    Designed for durability and long-term use
  • Automatic Shutoff Protection
    Prevents overheating when water levels drop
  • Fully Submersible Design
    Flexible placement inside your tank

Modern heaters are built to prevent overheating and damage when used correctly 


Real Benefits 

  • Keeps water temperature stable 24/7
  • Protects fish and coral from stress
  • Reduces risk of tank crashes
  • Set it once and let it run

This is a must have core piece of equipment


Choosing the Right Wattage

Use this general guide:

  • 25W → up to 5 gallons
  • 50W → 5–10 gallons
  • 100W → 10–25 gallons
  • 200W → 25–50 gallons
  • 300W → 50–75 gallons

Rule of thumb: ~3–5 watts per gallon depending on room temp


Pro Tip from Infinity & Beyond Aquatics

  • For added safety and more precise temperature control, we recommend pairing this heater with the
    IceCap Temperature Controller.

Perfect For
