You may want to confirm how many watts you are running and that it is operating correctly.
All right I will absolutely do that, thank you. Could the thermostat be the problem too? I know that it's not good to run both the RHP and the flexwatt on the same thermostat which is another reason I got the Herpstat 2, but i felt it was worth leaving it the way it is (mostly okay) rather than unplugging the flexwatt and losing more heat until the Herpstat comes
