I'm from Texas, and it stays relatively hot here with the exception of a few months in the winter. As its already starting to warm up, I wasn't too concerned about an additional heat source; especially since I am anemic and usually keep my house pretty warm as I chill easily. However, I'm not sure whether or not I should purchase a CHE just in case. Do those of you who live in warmer states use yours year around? And where can I get the bulb, lamp, and thermostat at a reasonable price?
