Take aquarium temperature control into the modern age with the SICCE SCUBA Contactless Aquarium Heater.

Designed for freshwater and saltwater aquariums, the SCUBA Contactless combines precise electronic temperature regulation with SICCE’s patented NFC contactless technology. Using the free ContrALL app, you can hold a compatible smartphone near the heater to check or adjust its programmed temperature without removing the heater from the aquarium.

The electronically controlled thermostat offers an adjustable temperature range from 59°F to 95°F with a precision tolerance of approximately ±2°F. Once the selected temperature is reached, an energy-saving operating mode helps maintain stable conditions while reducing power consumption.

Its high-density, shatter-resistant glass construction provides dependable heat transfer, while strong suction cups keep the heater securely positioned inside the aquarium. A visible operating light and built-in thermal safety shutoff provide additional protection and make heater operation easy to monitor.

How Contactless Control Works

The SCUBA Contactless uses Near Field Communication, commonly called NFC. Open the SICCE ContrALL app and hold a compatible smartphone close to the heater to read or change its temperature setting.

NFC control does not require the heater to connect to Wi-Fi. Because it is a close-range contactless system, the heater cannot be remotely monitored or adjusted while you are away from the aquarium.

Choosing the Correct Heater

Choose the heater according to your aquarium’s actual water volume, room temperature, desired water temperature, and aquarium placement. Colder rooms or open-top aquariums may require additional heating capacity.

For larger systems, using two appropriately sized heaters may provide more even heat distribution and additional protection if one heater stops operating.

Installation and Safety

Install the heater in an area with consistent water circulation so warmed water is distributed throughout the aquarium.

Always unplug the heater before removing it from the aquarium or performing a water change. Allow the heater to cool before exposing it to air or handling it.
