Chihiros Heater Pro – Smart External Aquarium Heater

The Chihiros Heater Pro 1000W is an advanced, app-controlled aquarium heating system engineered to deliver precise, stable, and intelligent temperature control for aquariums of any size — from small nano tanks to large, high-volume systems.

Unlike conventional aquarium heaters that rely on simple on/off thermostats, the Heater Pro combines smart software control, adaptive power management, and multi-layer safety protection to create a safer, more efficient, and more stable aquatic environment.

Intelligent Heating for Any Aquarium Size

One of the Heater Pro’s standout advantages is its extremely wide, fully adjustable power range. Output can be set anywhere from as low as 10W up to a full 1000W, allowing the heater to be tuned precisely to your aquarium’s volume, stocking level, and ambient conditions.

This means:

• Gentle, low-power heating for small or nano aquariums
• Efficient maintenance heating for medium-sized tanks
• Rapid, high-power heating for large aquariums, cold rooms, or fast recovery after water changes

Because power is adjustable rather than fixed, the Heater Pro avoids the common problems of oversized heaters cycling too aggressively or undersized heaters struggling to maintain temperature.

Dual Temperature Control with Natural Adjustment

The Heater Pro uses dual temperature control logic to maintain stability:

• High-power heating is used only when rapid temperature increase is required
• Low-power maintenance heating takes over once the target temperature is reached

This intelligent switching creates a more natural heating curve, reducing temperature swings, minimising thermal stress on livestock, and significantly improving energy efficiency compared to traditional heaters.

Chihiros refers to this behaviour as natural temperature adjustment, designed to more closely mimic stable natural aquatic environments.

Smart App Control via My Chihiros App

All heater functions are managed through the My Chihiros App via Bluetooth connection.

From the app, you can:

• Set and adjust the target (base) temperature
• Monitor real-time water temperature
• View current power output
• Select heating modes
• Configure automation and safety settings

The app interface provides clear, real-time feedback, making temperature management intuitive and precise.

Automation & Scheduled Heating Behaviour

The Heater Pro supports time-based automation through a customisable automation window.

Users can define a start and end time, during which the heater operates using Customize Mode logic. Within this window, the heater dynamically adjusts output based on temperature conditions and power limits set by the user.

This allows:

• Different heating behaviour during day and night
• Smarter response to daily environmental temperature changes
• Improved stability without constant full-power operation

Rather than simple on/off timers, this automation focuses on controlled, intelligent heating behaviour.

Heating Modes Explained

The Heater Pro offers three distinct operating modes:

Auto Mode

• Fully automatic temperature regulation
• Heater adjusts output dynamically to maintain target temperature

Manual Mode

• Fixed temperature and power settings
• Ideal for users who want simple, direct control

Customize Mode (Advanced Control)

• Set base temperature
• Set maximum power limit (up to 1000W)
• Works together with automation time windows
• Heater dynamically scales power within defined limits

Customize Mode is the most powerful option, combining scheduling, adaptive power, and temperature stability.

Adaptive Power Scaling up to 1000W

The Heater Pro includes an Automatic Heating Function designed for demanding situations.

If the target temperature is not reached within a defined time (e.g. after large water changes or in very cold conditions), the heater can:

• Automatically increase output in controlled power steps
• Scale up gradually, up to 1000W maximum
• Reduce output once stability is achieved

This ensures fast recovery without continuous high-power operation.

Comprehensive Safety Protection

Safety is built into both the hardware and software:

• Overheat protection with user-defined cutoff temperature
• Dry-burn / low water protection using a water level sensor that cuts power automatically
• Audible alert when a fault condition is detected
• Automatic shutdown in unsafe conditions
• Temperature calibration to correct probe deviation
• Password lock to prevent accidental or unauthorised changes

These protections make the Heater Pro suitable for both beginner and advanced aquarists.

Compact Inline Design & Display

The Heater Pro features a compact inline design, allowing clean installation within aquarium cabinetry or inline with filtration systems. A built-in digital display provides at-a-glance visibility of:

• Current temperature
• Target temperature
• Power status
• Bluetooth connection

Its slim profile makes it easy to integrate into modern aquarium setups.

AU / NZ Version

This model is supplied with a standard AU / NZ plug, making it fully compatible with Australian and New Zealand power outlets with no adapters required.

The Chihiros Heater Pro 1000W is not just a heater — it is a smart temperature management system. With adjustable output from 10W to 1000W, intelligent automation, adaptive power scaling, and advanced safety protection, it provides reliable, stable heating for any aquarium size while maximising efficiency and peace of mind.
