CHE is 10 inches from the floor. It's 100w. But from what I understand, they don't heat the air, only what is directly below it so what other heating options do I have? Ive also read that heat rocks aren't effective.
add another CHE and what you read is wrong CHE's produce a ambient heat yes there is a little focus but the red bulbs only warm directly below them with a lot more focus
is your top open or covered? if it's open that would explain heat problems
