I've just got a hydor 300 watt inline heater from my gf for xmas.. ( obviously I asked for it). I've already taken it to bits and disabled the built in thermostat. This means that when the powers on, the heaters always on now. I plug this into a proper thermostat controller which switches the heater on and off. My experience of both previous hydor heaters I've had are that the thermostats always go after a period of time. Either get stuck on heat which can cook your fish or they stop switching the heat on. I've also read loads of other stories around the world of people having the same problem. Make sure you get the right heater for your hose size as the 200 watt comes in both 12 and 16mm 🙂
