That only gives you 20 amps the way it works is each feed is getting 20 amps of regular old 110/120 V giving you 20 amp 220/240 volts at the motor. I seriously doubt that the electrician would use 10 wire on a 20 amp 220 circuit it would be 12 gauge. I would run a new circuit to the Heater with 10 wire and a 30 amp double pole breaker.
