YauBay Mini Preset Heater 32w TH04-A32 | Small Aquarium Heater

The YB Mini Preset Heater (TH04-A32) is a compact, fully submersible 32w aquarium heater designed for small tanks and low water-level setups where a full-size heater simply won't fit. It runs at a factory-set temperature, switching off automatically once that target is reached and maintaining it without manual adjustment — straightforward and reliable for smaller freshwater and aquatic terrarium setups.

Compact Design for Small Spaces

Its small form factor makes it well-suited to nano tanks, desktop aquariums, and terrariums where water depth is limited. It operates effectively in low water levels, giving keepers more flexibility in how they configure smaller enclosures.

Preset Thermostat Operation

The heater runs to a pre-set temperature target and stops automatically once that threshold is reached. There are no dials to adjust — the unit maintains its set temperature consistently, reducing the risk of overheating in smaller water volumes.

Safety Features

• Built-in overheat protection cuts the heater when the preset temperature is reached
• High-temperature resistant casing for safe, long-term submersion
• LED indicator shows working status at a glance
• IP68 rated — fully submersible in water

For keepers running small tropical fish tanks or compact aquatic setups, the YB Mini Preset Heater 32w offers a no-fuss heating solution with the safety features needed to run it confidently around the clock.
