Marina submersible C17 plastic heater is 17W and suitable for up to 17 litres.
Solid state, no glass, unbreakable. Outer case is constructed of tough unbreakable polymer. Designed to reach and maintain the preset temperature of 26 degrees celcius. Measures approx. 15cm x 2cm.
Just submerse, suction to the side of the aquarium and turn on. How easy is that??
