Reliable Temperature Control for Aquariums & Grow Setups

The RS Electrical 75W Aquarium Heater provides stable and reliable heating for aquariums and controlled environments. Maintaining a constant temperature is essential for tropical fish, aquatic plants, and other temperature-sensitive organisms.

This 75-watt submersible aquarium heater is suitable for tanks up to 75 liters (20 gallons) and helps keep water temperature stable for a healthy aquatic ecosystem.

Thanks to its compact design and reliable thermostat, this heater is also frequently used in mushroom grow setups, monotubs, and incubation containers where maintaining a stable ambient temperature is important for optimal growth conditions.

Adjustable Automatic Thermostat

The heater features an adjustable temperature range from 18°C to 32°C, allowing you to easily set the desired temperature for your aquarium or grow environment.

The built-in thermostat automatically regulates heat output, preventing temperature fluctuations that could stress fish or affect sensitive cultures.

Durable & Fully Submersible Design

The double glass construction ensures durability and safe long-term operation. The heater is fully submersible and distributes heat evenly through the water, creating consistent conditions throughout the tank or heating container.

Easy Installation

Installation is simple. Attach the heater to the aquarium glass using the included suction cups, adjust the desired temperature, and allow the heater to automatically maintain stable heating.

For mushroom grow setups, the heater can be placed in a water reservoir or temperature-controlled container to help stabilize the surrounding environment.
