RS Electrical Aquarium Heater with Thermostat – 200 W

The RS Electrical 200 W heater keeps aquarium water at a steady temperature in freshwater and saltwater tanks. A built-in thermostat switches the heater on and off to hold the temperature you set, two suction cups fix it to the glass, and a protective bottom cap helps guard the glass tube against breaking if it is knocked or dropped.

Key features of the RS Electrical Aquarium Heater

• 200 W heating power
• Built-in thermostat
• Fresh and saltwater use
• Two suction cups
• Protective bottom cap

Setting it up

Before switching it on for the first time, leave the heater in the tank for a while so the glass tube adjusts to the water temperature, then set the dial and check the result over the next day with a separate aquarium thermometer. A 200 W unit is a higher-output choice, so match the wattage to your tank’s volume and room temperature. In a long tank, two smaller heaters at either end can give more even warmth than a single unit.

Good to know

Fit the heater where water flows past it, keep it fully submerged to the marked level, and unplug it for about 15 minutes before taking it out of the water.
