It's 20 years old. You don't want to invest too much into it. But
there are two things it may be that are worth doing.
If electric, my guess is one of the heater elements is dead. Cheap and
easy to replace.
Gas or electric my have a dip tube problem. If it is broken it needs to
be replaced. The part is not expensive, but if you don't have much room
above the heater, then replacing it could be a problem.
