A #10 wire with an insulation rating of 60,75 or 90 degrees C is rated at 30 amps respectively.
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
Need to know the wire size.
Don't go over 30 Amps with a 10 Ga wire.
10 awg wire can have a breaker size of 30amps. It can actually carry more but as for codes the wire is usually allowed to carry 80% of its max capability which puts the breaker at a max size of 30 amps.
The wire rating for a # 12 wire is 20 amps. If you are going to continuously load the circuit you need to de-rate the wire by 80%. This brings the current down to 20 x .8 = 16 amps. The wire rating of a # 10 wire is 30 amps. 30 x .8 = 24 amps.
Couple of things wrong here. 30 isn't a wire size. If you mean a wire that can carry 30 amps that would be # 10. Now it depends on how many # 10 wires you want to put into a conduit that governs the size of the conduit.

A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.
Yes, a #10 wire will carry 30 amps for 30 feet. If the load is rated as continuous then the wire will have to be derated to 80% capacity which will leave you with 24 workable amps. If the load demands currents higher that 24 amps then you will have to go to the next wire size up which is a #8 which is rated at 45 amps.

10 AWG.
A # 10 wire with a insulation factor of 75 or 90 degrees C are both rated at 30 amps.
Sorry, there is no such wire size as "30 gauge" in the AWG (American Wire Gauge) system. For the ampacity rating of all standard conductor sizes, go to Table 310-16 of the National Electric Code. If you mean what wire size will carry 30 amps then a #10 copper wire insulation rating of 90 degree C is rated at 30 amps.
A #12 wire is rated at 20 amps, continuous loading at 80% = 16 amps. # 10 wire is rated at 30 amps, continuous loading at 80% = 24 amps.
