Aside from the above if you are paying heat chicago temperature control makes a temperature limiting thermostat if you pay heat.

Normal panels will start getting some voltage drop whenever the temperature rises about about 70 degrees F. 

No one knew that alternating current would make high-temperature coal-fired furnaces wholly obsolete by 1940.So here we are today out here, surrounded by quite a few SFR properties built by people who believed they were building for generations to come in a very stable area.

(average year round temperature is 65 degrees, never too hot or too cold)  It's a beautiful place to live and visit.

The temperature gets to 72 Fahrenheit on the hottest day here in the south GA when temperature outside is about 100 degrees. 

And I was pretty happy moving into a house vs. an apartment where the heat temperature was not controlled by me!

Units that will last, hold up to tenant use; ideally spot free.Not sure if to stick w/simple single operation style (on/off), or go for the dual handles that operate temperature separate from water flow.

You'll need to prove that the temperature is a health risk.

If the ceiling is under insulated and gets cold compared to the inside temperature, that can cause condensation to form.

Problem is that this house has been vacant for some time, and due to lack of temperature control and stagnant air, there is mold everywhere.
