You're in Texas, so the water cannot be freezing cold, unless you have the AC really, really low. It will feel chilly to you, even if it is 80 degrees because your body temperature is much higher. Purchase a thermometer if you do not already have one so you can determine the water's temperature. If the home's temperature is around 75-80 degrees, the heater will not turn on. Heaters often are not necessary at all in the summer time because homes stay so warm, especially in places like Texas and Florida.
