Work backwards from 20 W. The max. theoretical efficiency for Class "B" is 78.5%. In the real world, the efficiency will be lower. For sake of argument, we'll use 78.5%. 10 W./tube leads to 12.9 W. being dissipated.
Yes, the S5000 works the O/P tubes hard. Factoring near Class "B" (prevents cross over distortion) and real world losses into the calculus, both of which reduce the efficiency, means over 13 W. being dissipated/tube, at full power O/P. Don't think of anything other than EL84Ms in an S5000.
