Cool idea about hanging it up like that!

Power loss is proportional to current squared. Itt is linearly proportional to voltage, The peak current for the 4 HP is 9 amps. Heat is propotional to 9 squared or 81. Peak on the MB is 18 amps. heat is proportional to 244. 8 amp produces 3X more heat loss which heats the hose big time.

Is the only heat source from the motors, or is there an element as well?

There is no heater element beyond the heat from the motors.
