The ultimate heating solution for large UK aquariums, featuring a dual-display digital controller and corrosion-resistant titanium elements.
How to Use
- Mount the digital controller in a dry area of your aquarium cabinet using the provided bracket.
- Place the titanium heating element in a high-flow area (e.g., the return chamber of a sump or near a powerhead in the display).
- Position the temperature probe at the opposite end of the tank/sump from the heater to ensure accurate readings.
- Plug into a UK 3-pin socket and set your desired temperature using the 'Set' button.
- Calibrate the unit after 24 hours by comparing the display to a trusted mercury or digital thermometer.
What Our Customers Say
Bought the 1000W system for my 800L Discus tank. The temperature hasn't moved more than 0.2 degrees, which is vital for these sensitive fish. The Glasgow winters are harsh, but this handles it easily.
The dry-run protection saved me during a water change when I forgot to unplug the heater. Usually, that would be a cracked heater and a ruined day, but the AquariumPet unit just cut out safely.
Finally, a heater with a cable long enough for a large cabinet! The build quality of the titanium element is far superior to the glass ones I've used previously in my reef sump.
Excellent bit of kit. My only minor gripe is the suction cups for the probe could be a bit stronger, but the actual heating performance is flawless on my 600L setup.
As a marine biologist, I appreciate the accuracy. I've verified the probe against lab-grade equipment and it's remarkably consistent. Perfect for stable reef temperatures.
Great controller, very clear display. It's a bit bulky in the cabinet if you have a lot of other gear, but the peace of mind is worth the space.

Founded by a team of dedicated UK aquarists, AquariumPet was born from a frustration with underpowered heating systems in large display tanks. We understand that for tanks between 500 and 900 litres, a standard heater simply isn't enough. Our mission is to provide professional-grade, digitally controlled heating solutions that offer both stability and peace of mind.
Based in the UK, we focus on the technical requirements of the modern hobbyist. We champion the use of external controllers and redundant heater configurations, ensuring that even in the event of a component failure, your delicate ecosystem remains protected. Our products are designed to handle the high-flow environments of sumps and large-scale filtration systems.
At AquariumPet, we don't just sell hardware; we provide the expertise needed to install it correctly. From probe placement to calibration against trusted thermometers, we guide our customers through every step of the setup process to ensure rock-steady temperatures for both freshwater and marine livestock.
