Jolly Preset Heater - 22W - Sicce

The Sicce Jolly Preset Heater does one thing well: it maintains a fixed 77°F (25°C) in small aquatic and semi-aquatic enclosures without requiring the hobbyist to set or monitor a dial. Its plastic construction is designed to be virtually unbreakable — a meaningful distinction in setups housing turtles, large invertebrates, or animals that investigate equipment. The 22W model is sized for tanks up to 25 liters (6.6 gallons), making it a dependable choice for nano reef frag tanks, planted nano aquariums, terrariums, and paludariums where a small, low-profile heat source is needed.

One of the Jolly's more practical features is its ability to be placed directly beneath substrate. Most glass heaters require open water placement and suction-cup mounting on the glass; the Jolly can sit under gravel or sand, keeping it out of sight and out of reach of any inhabitants that might damage it. It operates continuously while submerged — there is no thermostat to dial in — and shuts off only when unplugged or removed from water. The built-in thermal protection engages automatically if the unit overheats or runs dry, preventing damage to the heater and the tank.

The chew-safe cord cover is a practical addition for reptile and turtle enclosures where inhabitants may interact with equipment. A slim, compact body keeps the footprint small, and the included suction cups provide an alternative mounting method when substrate burial is not preferred. Adhesive decorative panels in rock, wood, and plant textures are included to help the heater blend into naturalistic setups.

This heater is not the right fit for tanks requiring a user-adjustable temperature target — the preset at 77°F is fixed by design. It is best suited to tropical freshwater fish, turtles, and terrestrial or semi-aquatic reptile enclosures where 77°F is an acceptable or ideal target. Installation is straightforward: mount with suction cups or bury under substrate, plug in, and confirm the LED indicator is lit.
