It is very odd that you would have a 20A main breaker with 50A service. Are you sure it's not just a 20A branch circuit?

If it's just a branch, simply plugging the heater into an outlet on a different circuit should solve the problem.

If it really is the main, carefully check the gauge of the wire going to the breaker. If it is #10AWG or larger (meaning #8 or #6, not #12), only then can it be safely replaced with a 30A breaker, per the National Electrical Code.
