Thermometers may fluctuate but heaters do not. They either heat or they don't. They can be heating on the cooler side, but will consistently do that. We would recommend purchasing a new thermometer to check the water temperature. If it is the same as the room's temperature, or just above room temperature but less than 76 degrees, then you do have a heater issue. If the thermometer is reading less than the room temperature, the issue is the thermometer, not the heater.
The warranty on the heater is two years, with receipt. You would need to email your receipt and information to us via firstname.lastname@example.org along with the above temperature readings.
