Warming - Heating - Cooking

Water heaters make sense, at least, if the desired water temperature should be above room temperature. Most tropical ornamental fish feel comfortable in a water temperature between 24 and 26°C. Many shrimp species stem from cooler mountain streams and consequently prefer temperatures below 24°C. Only the invertebraes from Sulawsi like it really warm and require a temperature of 28-30°C.

Damit der richtige Heizer gewählt wird, sollten immer drei Faktoren berücksichtigt werden: Wasservolumen, Wunschtemperatur und Differenz zur Zimmertemperatur. Soll das Wasser bei einer Umgebungstemperatur von 20 °C um 5 ° auf 25 °C erwärmt werden, greift die alte Faustregel mit ungefähr 1 Watt/Liter.

Soll das Wasser aber z. B. in einem 100 Liter Aquarium im kalten Wintergarten (15 °C) auf 30 °C erwärmt werden, sind 200 W nötig! Umgekehrt macht es keinen Sinn, vorsichtshalber einen zu starken Heizer zu kaufen, der dann evtl. bei kleinen Wassermengen nicht schnell genug ausschaltet oder durch dauerndes Ein- und Ausschalten extrem strapaziert wird.

Profis verwenden bei größeren Wassermengen statt eines Heizers immer zwei Heizer, die nur gemeinsam die gewünschte Temperatur erreichen.
