D-D Titanium Heaters
The D-D range of pure titanium heaters is available in four sizes to suit all marine, reef, and freshwater aquariums.
D-D Titanium Heaters are manufactured in Germany using high-quality components and are shatterproof, saltwater proof, and virtually indestructible. These heaters are fully submersible and feature a continuous titanium jacket, thanks to the newly designed internal earth connection.
Titanium is completely non-corrosive in saltwater and one of the best conductors, delivering heat to aquarium water substantially better than conventional glass heaters, resulting in more efficient operation.

How does the titanium construction improve heating performance?
Titanium is a highly conductive material and is completely non-corrosive in saltwater, allowing for more efficient and consistent heat transfer compared to traditional glass heaters.
Is the heater safe for use in freshwater tanks?
Yes, the D-D Titanium Heaters are suitable for both freshwater and marine aquariums due to their durable and corrosion-resistant titanium construction.

Irene Chapman –
Installed the 300W model in my 200-litre reef tank. It has been running smoothly for over six months without any issues. The heater stays cool to the touch and maintains a steady temperature even during temperature fluctuations. No signs of corrosion or damage after prolonged saltwater exposure.
Zoe Fraser –
Switched from a glass heater to the D-D titanium model. The temperature control is much more stable, and the heater doesn’t degrade over time. It’s built to last and fits perfectly in my tank without any leaks or pressure issues.
Andrew Mackenzie –
The 250W version works well for my 220-litre freshwater tank. It heats up quickly and maintains temperature efficiently. A bit larger than expected, but fits well. No problems so far with saltwater exposure.
