Maintain your aquarium’s target temperature with the SUNSUN EH Series external heater, featuring LCD control, adjustable heating from 20–35°C, and automatic power-off when water flow stops.
-
Choose your heating output: Select the EH-300 300W or EH-500 500W version for your fish tank setup.
-
Use inline with filtration: Connect the heater to your filter bucket’s outlet tube so warmed water flows back into the aquarium.
-
Monitor settings clearly: The built-in LCD display lets you check the temperature while adjusting the control within the 20–35°C range.
-
Match your hose and socket: Included adapters fit 16mm inner-diameter hoses with 17mm connections or 20mm hoses with 22mm connections; a plug adapter supports UK, US, EU, and AU standards. Install it with the arrow pointing in the same direction as water flow.
