Why consider this model?

  • Type 3667 steps up to 200 W and a 386 mm (15.19 in) body. EHEIM's manual places it in the approximate 300–400 L / 79–106 US-gallon band. It is a plausible documented-capacity screen for a mid-size tank that needs an adjustable setting and WLAN control, provided its vertical length and waterline marks fit.

Tradeoffs to weigh

  • This is a larger, more involved choice than a basic analog heater: configuration and monitoring use WLAN, and deviation e-mail depends on the documented network and saved address. EHEIM's product page lists 18°C as the lower limit while the English manual says 68°F (20°C); this assessment uses the explicit US-manual Fahrenheit interval and keeps the conflict visible. The glass body is not documented as shatterproof; the official image shows a 220–240 V label and remains rejected. The page instead uses a wattage-matched ReefH2O listing photo tied to UPC 720686011687, but no voltage label is legible there, so check the offered package and unit.
