Is my thermometer broken?

[Justin_18]

Hi everyone,

I broke my last thermometer, so naturally i bought another one. There seems to be a problem however. The temperature never goes below 86 degrees. I felt the water and it does not feel this hot but I don't trust my sensory system as an accurate thermometer. The heater is set to 80 and it still comes on a few times a day. So is my heater right? Is it my thermometer that is messed up? Oh and I looked closely at the thermometer, and it appears to have something stuck in the bore, could that be causing the problem?

Thanks for any help in advance.

Justin
