100W Aquarium Heaters

The heaters had to be simple, easy to use, durable and affordable.


Having reviewed other heaters available on we noted that even the instructions were difficult to read in many of the products on offer by other suppliers.  Our instructions are easy to read in English.


We also identified that many products claim to last forever - this is not possible, heaters fail, they breakdown eventually.  This is a FACT.


Our instructions strongly recommend that two heaters are better than one.  When one stops working, which happens to all heaters, then the tank is kept at the right temperature by the one that still works - saving your fish and other creatures in your tank. 


This means you can purchase a new heater when one stops working, rather than wait until your only heater fails and the aquarium drops in temperature.


Two heaters use the same amount of energy as one heater as they only have to heat half the water each.


Jetsu offers a 1 YEAR WARRANTY: We believe in great customer service, if your heater breaks down we will replace it.


1. Our aquarium heaters must only be turned on when in water.

2. If you are going to be away from home and have asked somebody to look after your fish - you must make sure they know not to change the settings on your heater if the light goes out! 

You would be surprised how many times this has happened to our customers and they end up with boiled fish - you have been warned!

3. Please do not use our heaters with very aggressive fish like cichlids - if you have aggressive fish we recommend that you invest in a more expensive titanium enclosed heater.
