I’ve never had a problem with this heater. It’s always heated my water to my desired temperature. The only thing I would suggest is to monitor your water temperature within the first couple hours of introducing the heater as it needs some time to adjust. ### ⭐⭐⭐⭐⭐ Keeps things warm *by W***R on February 3, 2026* Works as expected. I use it for my chickens. I have their water in a 5 gallon bucket with those little orange nipple valves installed on all sides. I have this thing cranked up to 90 degrees and amazingly it keeps the water and the valves from freezing even when the temp dropped down to -9 degrees F. outside. So the chickens can get to their water on days when a water bowl freezes solid inside of a couple hours. ## Frequently Bought Together - HITOP 50W 100W 300W Adjustable Aquarium Heater, Submersible Fish Tank Heater Thermostat with Suction Cup (300W) - PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/186091208-300w-adjustable-aquarium-heater-submersible-fish-tank-heater-thermostat-suction](https://www.desertcart.vu/products/186091208-300w-adjustable-aquarium-heater-submersible-fish-tank-heater-thermostat-suction) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
