Watering Temperature for Tomato Plants?

We are watering our tomato plants from a holding tank and the water becomes very hot. Does watering with hot water affect the plant?
ANSWER:
Warm or tepid water is fine for watering tomato plants. But if the water actually feels hot to your touch, it is best to let it cool to body or room temperature before watering your tomato plants. Hot water might not kill the plants outright, but it can stress them.
