The Eheim Themocontrol heaters are a new line of Eheim heaters that are more precise than the Eheim Jager heaters. They control heat electronically. Due to their laboratory grade glass coating that increases heating surface, they keep the temperature in the aquarium more stable. The glass acts as a heat shield that will not harm the inhabitants of the aquarium. The heaters can be fully submersed as they are fully waterproof.
