I have a fairly new 150 watt heater that has been working fine. What I'm noticing is that I adjust it to the temp that I want based on outside influences i.e. Winter weather, 68 deg in the house, lighting etc. then when the sun hits the room the tank is located in the temp jumps from 78 to 86 in just a few hours. This is a 29 gallon tank. My best guess is that the heater is not reading ACTUAL temperature and therefore is only keeping it's OWN temperature steady not necessarily WATER temperature. Has anyone else realized this or come across this? I don't want to have to adjust my therm every single time the outside conditions change. Any heaters actually track water temp instead to assure accuracy?
