Drinking water can't possibly make you lose weight. You need a healthy and balanced diet. If you had the water in place of a meal, it might help weight loss, but not adviseable. The effect would be mainly by temporarily filling your stomach, and water would empty out quicker than food. And the temperature is irrelevant, as by the time it reaches your stomach, it'll be about the same temperature anyway.
