Explore this buying guide ↗Why consider this model?
- Consider the 100 W Type 3634 when an aquarium is within EHEIM's approximate 100–150 L range (up to 39.6 US gallons), an adjustable 68–90°F range covers the independently chosen target, and the tank has room for a roughly 12.2-inch-long vertical glass heater.
Tradeoffs to weigh
- The published maximum is 39.6 US gallons, not a guarantee of heating in every room. EHEIM describes impact-resistant glass, but the heater is not documented as a shatterproof-body model; the US voltage label, minimum water line, immersion guidance and vertical placement must be checked on the exact package and manual.
