Of course it "works" except 150 BTUs isn't going to cut it. You would need dozens of candles to provide any useful amount of heat.

If it is a question of sealing off a small interior room and having a stock pile of hundred or so tea candles already on hand and using 4 or more at a time I would still try it in an emergency. Granted a situation in Texas that will last for days (weeks?) would not be practical but for a couple of bucks in supplies it might help you survive a couple of freezing nights.
