Sera 100 W Aquarium Heater
The sera 100 W heater is a compact yet powerful immersion device designed specifically for freshwater and marine aquariums ranging from 70 to 100 liters. Its engineered simplicity, combined with advanced safety features, makes it an essential component for maintaining stable water temperatures in both hobbyist and professional settings.
Key Design Features
- Shock‑resistant quartz glass: The heater’s housing is constructed from high‑quality quartz glass that can withstand sudden temperature changes without cracking, ensuring longevity even under demanding conditions.
- Fully submersible construction: Every part of the unit is waterproof, allowing it to be placed directly in the tank without risk of electrical hazards or water damage.
- Integrated safety circuit: A built‑in protection system automatically shuts off the heater if the temperature exceeds a preset threshold, preventing overheating and potential fire risks.
- Protective enclosure: The device includes a protective cage that guards against accidental contact with the heating element, reducing burn hazards for both humans and aquatic life.

Installation and Usage Guidelines
- Placement: Position the heater at the bottom of the tank, ensuring it is fully submerged but not touching the tank walls or any décor that could obstruct water flow.
- Connection: Plug the unit into a grounded outlet. Avoid using extension cords that may introduce voltage drops.
- Tuning: Adjust the thermostat to the desired temperature setting (typically 24–26 °C for tropical fish). The heater will automatically maintain this level by cycling on and off as needed.
- Maintenance: Periodically inspect the quartz glass for signs of wear or mineral buildup. Clean gently with a soft cloth; avoid abrasive cleaners that could damage the surface.
Safety Considerations
- The heater’s safety circuit ensures it will not operate above its maximum temperature, protecting both the aquarium environment and surrounding surfaces.
- Because the unit is fully submersible, there is no risk of electrical shock when used correctly. Always verify that the power cord remains dry and intact.
- The protective cage prevents accidental contact with the heating element, which could otherwise cause burns or damage to delicate aquatic organisms.

This heater is suitable for a wide range of aquarium types:
- Freshwater tanks: Ideal for tropical fish such as guppies, tetras, and bettas.
