Eheim Thermopreset 200 Aquarium Heater

EHEIM Thermopreset 200 Aquarium Heater

It really doesn’t get much simpler than this. The EHEIM Thermopreset 200 Aquarium Heater is engineered to maintain a constant 25°C, the ideal temperature for most common tropical aquarium inhabitants. With no adjustment dial and no setup required, it’s a true plug-and-play heater designed for stability, safety, and long-term reliability.

Thanks to high-precision electronic temperature control, the Thermopreset 200 delivers excellent temperature accuracy, while the highly efficient heating element ensures even heat distribution throughout larger aquariums. Compared to the Thermocontrol range, the Thermopreset features additional plastic protection, offering increased mechanical strength and durability.

Its slim 28.2mm diameter keeps it discreet in the aquarium, even in minimalist setups. An integrated LED indicator shows when heating is active, and dry-running protection adds an extra layer of safety. Suitable for both freshwater and marine aquariums, and backed by a 3-year EHEIM warranty, this heater is built to be trusted.
