Best Answer: A tethered hot air balloon flight will typically be between 50-75 feet. It's high enough for the passengers to get a feel for the height and manageable enough for rope length. I have heard of some gas ride balloons that are on a winch go higher. To tell you the truth, I can't recall the max height for tethering. It wouldn't be different than for gas balloons.
Outside Air Temperature + Heat it Takes to Fly (140 F) = Temperature Inside the Balloon. Cold day of 30 degrees F + 140 F = 170 degrees inside the balloon. Hot day of 95 degrees F + 140 F = 235 degrees inside the balloon (more heat if it's hot out) This is of particular concern to companies operating smaller balloons. The smaller the balloon, the less lift capacity it will have and the hotter it must be inside the balloon for it to fly. The maximum continuous operating temperature for most hot air balloons is 250 degrees Fahrenheit.
