Heating for aquarium fish
Fish adapt to the ambient temperature. The life functions of cold-blooded animals sink with falling temperatures. The right aquarium temperature is therefore very important to ensure their problem-free food intake and a smooth functioning of their metabolism. Depending on the origin of the fish, the temperature they feel comfortable at varies.

Easy to install
Put the heater into the protective basket included. Preselect the required temperature using the temperature dial and immerse the heater in the water at least to the “min. water level“ line. Fasten with the suction cups. A control lamp lights up as soon as the heater is connected to the power supply. The heater can also be mounted horizontally, e.g. for turtle tanks.

Ideal temperature transfer
JBL’s safety heater thermostat ensures an ideal temperature transfer in the range between 20 - 34 °C. With the help of the dial a control accuracy of +/- 0.5 °C is ensured. The maximum attainable temperature depends on the water volume and the difference in temperature to the surroundings.

Safety heater thermostat
The protective basket in which the heater is embedded prevents the fish from being scorched. The heater is watertight, can be immersed to a depth of 100 cm and, with its 2 mm strong safety quartz glass, is very stable. If the water level sinks or the heater is removed from the water, a safety protection device in the heater interrupts the electric current and prevents overheating. The heater is TÜV certified.

FAQ
When I touch the heating cable under water, it is only warm.

It is by all means correct that the JBL ProTemp S heating element only emits what is perceived to be pleasant warmth by the hand. The surrounding water causes the heat to be conducted away very quickly and passed on to the water. Therefore, the heating element is functioning properly. If it is taken out of the water, the glass immediately becomes very hot. The safety shut off is activated immediately. Nevertheless, the resulting heat must escape outside the water after the heating is switched off, which may cause the heater guard to become deformed, as there is no water to cool it. The safety thermoswitch in JBL ProTemp S heaters is by no means intended as an automatic control device which makes it unnecessary to pull the plug before a water change and, instead, is merely an additional safety precaution against accidents involving electricity. Due to its design, the heater may become very hot before the thermoswitch turns it off.

Is it possible that there is a series of JBL ProTemp S heaters with in/out intervals that are not adjusted properly?

According to technical specifications, our heaters have a control accuracy of +/- 05 °C. Taking measuring errors in temperature measurement for aquarium operation into account, the switching accuracy should be approx. 1 to max. 1.5 °C. If a heater has deviations of 5-7 °C, there is usually only one possible cause.

The heater is not adjusted properly, which can be determined by checking whether the heater has or has not a push button for readjusting (JBL has several different series). Otherwise it is defective. The heater is mounted in a spot that does not have sufficient flow of water.

Deformations have occurred on the protective baskets of the ProTemp S heater. What is the reason and what can I do about it ?

The protective baskets protect the ornamental fish against burns from the heating element.

If the heater is in operation it gives off heat to the surrounding water. With calcareous water scale (precipitation of calcium carbonate) can form where the glass meets the water and this reduces the thermal dissipation. An excessive formation of scale may cause heat accumulation which can lead to overheating and a deformation of the protective baskets.

With hard tap water a regular decalcification of the heating elements e.g. with JBL Clean A or JBL pH Minus is recommended.

Does the thermostatic switch in the JBL ProTemp S heater mean it is no longer necessary to disconnect the mains by pulling out the mains plug before a water change ?

The thermostatic switch in the JBL ProTemp S heater does not mean that it is no longer necessary to disconnect the mains by pulling out the mains plug before a water change. It is just an additional safety precaution against accidents with electricity. Due to its construction the heater can get very hot before the security switch switches off. This may cause a deformation of the protective basket.

Is the basket available as a spare part, or do I need to buy a new heater?

The protective baskets are available as individual parts. You need the following to fully replace the basket, e.g. for the ProTemp S 200 W:

1 x 6043100 - End part
1 x 6043200 - Short middle part
1 x 6043300 - Long middle part with a suction cup
1 x 6043400 - Upper part with 2 suction cups

Any one of our retailers should be able to order these in case they do not have them in stock.
