hygger 2 in 1 Submersible Aquarium Heater with Water Circulation Pump
Heater with water circulation assistance 
Heating (300W/500W/800W/1000W)
Unique idea, allows to operate the heater with wavemaker together or separately, optimizing energy use. During colder months, both functions can work in tandem to maintain warmth and water movement, while in warmer seasons, the wavemaker can be used independently to save energy.
Water Circulation Assistance （Upgrade）
Turn on water circulation to simulate natural currents, improving oxygenation and fish health, or off to let the heater work independently. Perfect for both calm freshwater tank or a dynamic reef aquarium, simplifies setup, saves space, enhances tank aesthetics while catering to diverse tank needs.
Functional Advantages 
All-in-One Heating and Water Circulation
Our water circulation heater ensures consistent water temperature in most areas and prevents localized overheating of the heating element. In contrast, single heaters without water circulation systems often lead to uneven water temperatures and may overheat, causing them to shut down.
User-Friendly and Centralized Control
The water pump has been replaced and upgraded, resulting in a higher water flow rateThicker shell blocks more motor noiseUpgraded suction cups (larger & softer) reduce tank wall rattling Increased water pump lifespan, changed internal materials
The external controller has a 3-digit temperature display, which shows the set temperature and real-time temperature, as well as various working status and error indicators.Temperature range 59℉~93.2°F/15°C~34°C. Hold down the right PUMP button to switch between ℃ and ℉.
2-in-1 Design: Heater Tube + Motor Impeller, Delivers Heating & Water Circulation. Only one device needs to be installed. Easy maintenance, reducing the complexity of maintenance. Centralized control, the same external controller can easily use.
There are 4 wattages in total, 300W/500W/800W/1000W. The product size of each model is the same, consisting of a 3.9ft long power cord + an external controller (2.62in long, 1.15in wide, 4.77in high) + 4.9ft long cord + heater with suction cup (7.4in long, 2.8in wide, 4.5in high).
The 2 side covers can be removed by turning, cleaned with a pipe brush (not included). Recommended to clean regularly to avoid clogging of the wave pump port, accumulation of dirt on the heating wire, which affects the accuracy of temperature control. The removable suction cup is also easy to clean.
Safety Features 
Auto Shut-off
The heater and water circulation pump automatically switches off when out of water, the icon remains illuminated, and a “beep” alarm sounds.
Motor Malfunction
When an object is jammed or the motor reverses,the water pump will stop, heating will also be suspended. Subsequently, every 5 seconds, the motor will attempt to restart to verify if it can function properly. If it can, the heater will resume normal operation and commence heating.
Safety Features 
Overheat Protection
In the event of a high-temperature alarm(exceeds 35°C/95°F), the high-temperature icon remains illuminated, and a “beepalarm sounds, and the heater will shut off, but the water pump will keep running.
Low Temperature Warning
If the water temperature is below 15°C/59°F, the low-temperature icon remains illuminated, and a “beep’alarm sounds. However, the heater will continue to operate.

ENERGY EFFICIENT: The product consists of two parts: a heating tube and a water pump impeller. This all-in-one heater circulates water as it heats, distributing warmth evenly throughout your tank. It eliminates the need for a separate pump, reduces the number of devices, saving energy, space, and ensuring a consistent. The integrated design is more energy-efficient, lowering power consumption
AQUARIUM HEATING ELEMENT: The internal heating element is made of high-grade corrosion-resistant 840 stainless steel and high-temperature resistant nickel-chromium heating wire, combined with magnesium powder thermal conduction technology. This ensures long-term durability in both saltwater and freshwater, providing fast heating, safety, and longevity
WATER CIRCULATING: Both functions can be used independently. During warmer months, can turn off the heater and use only the water circulating to enhance water flow, promoting oxygen exchange, which benefits fish and plant health. It also reduces sediment buildup, keeping the environment clean
VERSION 2.0 UPGRADE: Upgrade the impeller water pump to enhance water flow performance.The water pump function increases water flow, forms a water circulation, preventing stagnant areas and improving water quality. Even heat distribution is achieved as the water flow helps disperse heat, avoiding localized overheating
QUIET UPGRADED DESIGN: This enhanced hygger aquarium heater now operates significantly quieter. A thicker casing blocks internal motor noise, softer larger suction cups reduce tank vibration. And increased water pump lifespan, changed internal materials
EXTERNAL CONTROLLER PRECISE TEMPERATURE CONTROL: Features a clear 3-digit LED display that shows real-time and set temperatures, making it easy to adjust and monitor water temperature. Ideal for freshwater and saltwater fish, ensuring the water temperature remains stable within the set range

High Quality Aquarium Heater
I had initially bought two store brand dial heaters for my new 36 gallon aquarium, but after having trouble getting an accurate temperature reading from the same dial heater in my 10 gallon, I decided to try this Hygger Aquarium Heater with Upgrade Water Circulation instead, and I’m really glad I did.This Hygger heater is a little bulky, but it will become more hidden as my plants grow taller. No set up required; just plug in, set temperature, and go. The control panel was a little confusing at first in regards to running the heater and circulator pump together or separately. When setting the temperature, there’s no up/down buttons. Meaning if you click 79° but meant to click 78.5°, you have to keep clicking through to eventually reach your desired temp again. It’s a very minor inconvenience as I would rarely need to adjust the temperature. The control panel can be hung on the wall for easier access.I’ve been running this heater for a few days now, and it’s done a great job at maintaining an even temperature throughout the tank. The heater is very durable and seems like it will hold up well for a long time. The air flow from the pump on the side is gentle and does not disturb my plants, instead it gives my plants very slight movement, which is pleasing to the eye.This aquarium heater is high quality from a very reputable brand, an excellent value, and it’s perfect for my needs!*Note: my aquarium is newly set up and still in the process of cycling and aquascaping. The brown film on top of the heater in my photos is from kicking up the substrate while planting.

Don’t buy this particular product any other product by hygger I recommend but not this one
Hygger is one of my favorite makers for aquarium products every heater in my home in all my tanks are by hygger, I’ve never tried their wave makers, but I’m willing to try them back to this heater extremely horrible. The motor goes out heater stops working doesn’t heat doesn’t be loud. It goes unnoticed. Stop working after four months. I got it working again for it to stop again with a code error that never reset it wouldn’t heat fan wouldn’t work. It is no access to the fan Blade motor. Worst heater to buy kept it in a 90 gallon sump didn’t do so good wouldn’t put this inside of aquarium since it tends to suck up water when it wants to. I was popping up an error code if you do buy this product before you use it make sure it’s emerge and shaken very well so there’s no air inside of it since the motor might not start kicking and it might not suck water right away. Didn’t last as long as I expected to last for the pricing horrible heater.

Great heater with circulator!
This is a great space saving combo unit by having only one device in the tank and one cord to plug in. The heater / pump is well made with quality materials. The controller is very user friendly and allows for the heat and circulation to be run independently which makes the functionality of this little machine very useful. The heat output from this is accurate. The circulation ensures even temperature throughout the tank. There are multiple safety precautions against temperature extremes and low water level to prevent dry run of the unit. The circulator is very quiet. The suction cups are attached to a holder piece which slides right over the main unit making installing this very easy and can allow for flexible positioning in the tank.

Heats, but that’s it.
The pump broke down immediately after 24 hours. Heater still works, so I’ll give it points for that. But it’s huge due to it supposed to be able to pump the water and dissipate the heat more efficiently. So now I have this giant heater that doesn’t do the one thing it’s supposed to, due as the reason for its size. Also seems to constantly heat above the set temp. It heats that’s for sure. But cannot recommend for reasons it advertises.
Collars are great. Came as ordered. But size is not true. I ordered these for pups but they don’t go quiet as small as I’d like. But they will grow into them and they look amazingly nice. –
