Round Mechanical Thermostat Heat Only is rated 3.7 out of 5 by 95.
Rated 5 out of 5 by from Simple Installation, does the job. The instructions were very clear, I did verify it with a YouTube video to be sure I connected it correctly. Took longer to read the instructions than to install the thermostat. It's old-school style and function but fits in my 'tiny house' 1962 mobile home very well! As you can see, still working on it. It doesn't have an 'off' setting so I have to either turn the thermostat down well below a temp that would fire it up, or use the shut off on the furnace. Not difficult, just something to be aware of.

We had a digital thermostat , it got stuck all of the time , the batteries would die and it never kept the house at an even heat . We went back to the older round style like this Honeywell thermostat that I bought and I have never been so pleased in all of my life . It requires no batteries , it mounts very easily on the wall and the best thing is that it keeps the house at an even heat all of the time . I will never buy a digital thermostat ever again . I would recommend this thermostat to anyone . I love it .

This thermostat is much better than the programmable one that came with my house. The programmable one requires batteries and if they die, so does your heat. This one is simple to use and works all the time.
