You could purchase a Herpstat II (spyderrobotics.com) which would control both heat sources
I disagree. I think it is bad advice to a newcomer to say a thermostat is absolutely required. I think a dimmer switch is just as effective, so long as the keeper is willing to keep in mind that fluctuations in the room will affect the tubs, and that it may require tweaking several times a day. The fact is, a lot of keepers, especially the beginner keepers, just dont have the money to drop a couple hundred on a thermostat. I think a 10 dollar dimmer switch is a much better option if and only if the keeper is willing to go the extra mile for tweaking it to save them the hard hit on the wallet.
