We have those fancy pants fireplaces in our house that are gas, but you make them work with a remote control that has an internal thermostat.
These are great. You can set the temperature to 68 degrees in the day time and 64 at night and it self regulates.
Anyway, I just figured out the downside to having fireplaces that run on remote controls.
If you lose the aforementioned remote you just stay cold.
