    I am just about done building my new incubator, im having trouble with the thermostat. If the temp is low and you start to creep up, all of the sudden the temp wants to skyrocket.Im having a hard time fine tuning it. Has anyone had trouble like this before? This is the thermo im using. http://incubatorwarehouse.com/bi-metal-egg-incubator-thermostat-kit.html Im thinking of trying the Wafer thermostat, do they need to be in the incu or can they be mounted on the outside? thank you

    Thermostats need to be inside the incubator. As close to the heat source as you can. Having a fan behind the heat source and thermometer in front works really well.

    The bi-metal type thermostats (including water heater thermostats) were not designed for incubation. Wafer thermostats work great.

    They can be altered to be just as accurate as wafers,all I use is the hot water stat with no variance in temp

    Do you put the hot water stat in the incubator? do you have to open lid/door to adjust?

    They go inside the bator. On mine I drill a hole in the back and use a screwdriver so I don't have to open the bator. Make sure if you are using the water heater thermostat you do the modification with the extra holes drilled into it. I have started using this thermostat and it works great.

    Thanks cannedman, i just put a wafer thermo in and it seems to be working great. Now i just have to figure out how to keep the humidity up, my fan seems to be blowing pretty good, i may need to put a deflector in it.

    Are you doing the dry hatch method? What I have found that works great is a meat injector. You just insert it into one of your vent holes and insert a small amount of water until you get the humidity to were you want it. Just make sure you don't get the water on the eggs.
     
  10. Not true on the "as close to the heat source as possible" this is only the case with a water heater thermostat.

    As for the op...I suggest you stay away from bi-metal and try a standard wafer thermostat
