Do your heating pads burn out fast?

I buy the regular ones you get in the Reptile stores and even use a thermostat but they only last 2-6 months. Any ideas? I only set the thermostat at 95 degrees.

Do you have them running through a surge protector?

I know the brand shouldn't matter, but what brand do you buy?

Do your heating pads burn out fast?
No but I sure do(burn out fast) Ha ha
It really seems like something or some element is making them burn out pretty quickly if you ask me,because I have some pads last years,so maybe its the element around pads like moisture,coil pinching or Iregular currents in your house?

The brand is Zoo Med. It's the largest sized pad I saw in the store. The cage is 4ft.X2ft.X2ft. It's NOT hooked up to a surge protector.

It still produces some heat, but it's definitly not 95 degrees which is what the thermostat is set at.

Hook it up to a surge protector.

What temp is the room they are in usually they will only raise ambient temps abot 10-17 degreees in the cage.Example 70 degree room your only gonna raise pad temp to 85-87 or so a cold room will drag down even the best pads.
