Aquarium heaters are simple and basic devices that generate heat so that proper water temperatures can be maintained in fish tanks. An aquarium heater is actually comprised of two components: the heating element and the thermostat. The thermostat gives you the ability to control the temperature of the water in the tropical fish tank.
Some of the higher quality aquarium heaters come with five year warranties, valid when the unit is properly used. Other heaters come with twelve month warranties, but are generally good choices, just a bit less expensive. Still, regardless of the length of time on a warranty for an aquarium heater, the warranty does not cover the cost of replacing your fish if the heater malfunctions.
