Master the Climate of Your Large-Scale Aquarium
Professional 500W-1000W heating systems with digital precision for 500L to 900L setups.
AquariumPet
The ultimate heating solution for large UK aquariums, featuring a dual-display digital controller and corrosion-resistant titanium elements.
Precision Control for Large Volumes
Maintaining a stable temperature in a 500L to 900L aquarium requires more than just raw power; it requires intelligent management. The AquariumPet Pro Digital system separates the heating element from the controller, allowing you to monitor temperatures at a glance from outside your cabinet. The titanium construction ensures rapid heat transfer while remaining completely resistant to the corrosive nature of marine salt or the humic acids of South American blackwater setups.
Safety and Redundancy
For systems over 500L, we recommend a redundancy strategy. Our controller can manage multiple elements, ensuring that if one fails, the other maintains the biological minimum. The integrated thermal fuse and dry-run protection provide an essential safety net, automatically cutting power if the water level drops below the sensor during maintenance or due to evaporation.
Optimised Installation
Designed for the British fishkeeping hobby, our system includes long 2-metre cables to reach from the depths of a 6ft display tank or a deep sump back to your control board. The external temperature probe features a suction-cup mount for high-flow areas, ensuring the controller reacts to the true temperature of the water column rather than 'dead spots' behind decor.

- 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.

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.
Alistair Murray, Glasgow
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.
Siobhan O'Reilly, Manchester
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.
Arjun Sethi, Birmingham
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.
Gareth Williams, Cardiff
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.
Dr. Fiona Campbell, Edinburgh
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.
Mark Thompson, Leeds
Frequently Asked Questions
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.
