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.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
