YauBay Mini Preset Heater 10w TH04-A10 | Small Aquarium Heater

The YB Mini Preset Heater (TH04-A10) is a compact, fully submersible 10w aquarium heater built for small tanks and terrariums. Its preset thermostat design removes the guesswork — set-and-forget heating with automatic cutoff, making it a straightforward choice for nano aquariums, quarantine tubs, or low-water setups where a full-size heater simply won't fit.

Compact Design for Small Setups

The slim, small-footprint body is designed to operate in low water levels, making it suitable where conventional heaters can't function reliably. It works across small aquariums and terrariums, fitting spaces that larger heating units cannot accommodate.

Preset Temperature Control

Rather than a manually adjustable dial, this heater operates at a factory-set temperature. The unit automatically stops heating once that temperature is reached, then resumes as needed — maintaining a consistent thermal environment without any intervention from the keeper.

Overheat Protection

Built-in overheat protection cuts the heater off automatically when the preset limit is reached. This is a meaningful safety feature in small-volume water, where temperatures can rise quickly if a heater runs unchecked.

IP68 Rated — Fully Submersible

The IP68 rating confirms this unit can be fully submerged, with a high-temperature-resistant housing for safe operation. An LED indicator light shows working status at a glance, so you can confirm the heater is active without disturbing the tank.

For keepers running nano fish tanks, planted shrimp setups, or small reptile water features, the TH04-A10 delivers reliable, low-maintenance heating in a form factor that actually fits the space.
