I still use water heater thermostats.

The gentlemen are correct - a heat source near the thermostat causes the thermostat to cycle more often but keeps heat much more even over time.

I have made four incubators all with water heater thermostats and worked on light/heat source placement and monitored them. By far the shortest variation in temperatures is achieved in the way they offered you. Shorter more frequent cycles.

You can do it the other way. Your swings will be WIDER and your egg temp will vary as much as .5 -.8 degrees over the cycles. That will hatch eggs. Efficiently even.

I am more at peace with a tighter range. It is more comfortable and the results are even more reliable.

An interior air temperature that varies up to five degrees will still keep the egg temperature at between .5 and one degree of difference. That works.

But more consistent is better. Less variation has more predictable results. They are not saying something that they themselves have not verified and it matches my work as well.

While you can read a thing. Having lived with it and worked with it, we have given you our experience of it.

I don't like wafers. I either use a water heater thermostat or electronic ones when I have the money for the build. I will use a wafer for back up.

You can actually make a water heater thermostat perform reliably and well if that is the money you have.

Wafers I do not prefer.

Electronic ones, those are better, yet.

I have an experimental bator going on in a cooler, and I'm about to tear my hair out. (It has a water heater thermosat) I think that I might spend $10 more so I don't have to worry if it's going good or not.

It's worth $10 to me!

Great comments ! i realy liked your information . thanks all BYC cummunty you guys ar great !
thank you in arabic : شكرا : shokran

The actual temperature at the thermostat can be very different than the temps at or near the eggs. The temps at the egg are what you must concern yourself with. The wafer and water heater thermostat are placed close to the heat source to effect the cycle time of the heating element to regulate toward the correct temperature at/near the eggs. If you dis-assemble a hotwater heater thermostat, you will see that it is just a wafer thermostat encased in a plastic housing. The plastic housing effects the warmup/cooldown time of the wafer and extends the time that the heat source is off or on. The closer you can place it near the heat, the less time it takes it to turn off once the heat source is activated. The actual temperature range at the thermostat might be much higher than the actual temps at/near the eggs.

If you can find a digital thermostat, it will use a temperature sensor that can be placed at/near the eggs. this type of thermostat will generally be much more heat sensitive than the mechanical wafer type thermostats, but be much more simpler to adjust to the desired temps. Proper design of the heating system, as well as air flow is necessary to insure that you obtain even heating inside every cu-inch of the incubator interior, otherwise you could have cool or hot spots resulting in poor hatch rates.
