Okay, I missed the part about it being a water heater thermostat. I thought we were talking about an ambient heat thermostat. I am sorry and I hope I didn't offend you.
I have a few questions for you though.......When I bought my house it had electric baseboard heaters throughout the house. Each room had its own thermostat. The baseboard heater in my bathroom was only about 18" long and I kept it thinking maybe someday I would experiment with it using it as a heat source for a homemade incubator. The heat settings on the thermostat go up to 110 degrees.
Here is the question: In your opinion would this system work as a heat source for an incubator and if so, what size would you suggest I build the incubator? I could mount the thermostat outside of the incubator as, and I think I'm correct about this type of thermostat, when you set it for a certain temp. it stays constant and does not turn the heat source off when it reaches the temp it is set for. It may not be called a thermostat at all. It could be called simply a heat control device. If I am correct about this unit and the heat source does not shut off, would the temp. in an enclosed area, such as an incubator, continue to just keep climbing upward or would the temp. stay the same when it reaches the temp. it is set for?
Your input on the above would be greatly appreciated.
Thank you and again, I apologize if I offended you by my statements.

Thermostats are thermostats. The difference between them is the dead-band. This is the 1-20 deg range from the time the thermostat turns off to the time it turns back on. The closer you can get this dead-band to a zero the better. So any thermostat will work, some will just work better. thus the reason for drilling holes in the water heater type. this allows the temp to activate the setting quicker. Check whatever thermostat you get for the dead-band, then try to tweek it by placing the sensing device closer or farther from the heat source. The happy medium is the best.
When I made my cooler-bator, I first had a 5 deg dead-band in the water heater thermostat, after drilling and relocating, I managed to get the dead-band down to 1.5 deg!
