Description

The fully electronic Dennerle Heater Constant control heaters for aquariums can be ideally concealed in the aquarium thanks to their compact design and are therefore particularly suitable for nano aquariums. The housings are made of unbreakable special plastic. The temperature is fixed at 25 °C – ideal for most aquarium inhabitants that come from tropical climes. Thanks to the high control accuracy, the water temperature remains constant and protects all aquarium inhabitants from unfavourable temperature fluctuations. The wide, flat heating element emits the heat gently and over a large area.

Willem Joubert ★★★★★

"The service at Dorry Pets is excellent. The lady at the counter helped me step by step and showed me how to establish my fish, how to start and also what to look at. They even advised what to do during loadshedding. The service is great. I can't wait to establish a long term relationship with the store!"

Steven Nagel ★★★★★

"The team at Dorry Pets have gone over and beyond to help me! Always have time for me, and incredible results! Here is an example of my 30 liter tank before and after the CO² system; just unbelievable! The whole team will take their time, and not try forcing a sale. Thanks, much appreciated 😎"
