If you absolutely have to remove the heater, which I dont recommend in the least, but, never the less, if you have to remove it, please make sure you keep the tank in the warmest room of your house, and do not let it fall under 70*.
I have kept betta's without heaters for a few weeks at a time here and there without any major issues other than sluggishness as long as the tank stays at 70*+
