This is a voltage drop question. The circuit's voltage must be stated to answer this question.
There is no rating for #14 wire in the electrical code book. This is because #12 aluminium wire is rated at 20 amps and that is the minimum of home wiring circuit wiring in aluminium. It is not, if at all, used anymore. #10 at 75 or 90 degree C is rated both at 30 amps. #8 at 75 or 90 degree C is rated both at 45 amps.
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
Copper wire current ratings assume 10 amps per mm2 for currents up to a few amps. 26 AWG wire has a cross sectional area of 0.13 mm2 so this logic says 1.3 amps.

A 10 AWG wire is typically only rated for 30 amps, but conditions such as length of run, whether the wire is to be used in a "plenum", temperature and other factors may affect the type of wire that you must use for a specific application. If you have any questions, contact a qualified electrician or your local building inspector.
Standard recpt. for house hold is 15 AMPS wired usually with 14 awg, but applicance circutis are 20AMPS wired with 12awg. Dryer rect. are 30AMPs wired with 10 awg and Ovens are 50 Amps wired with 6awg.

There is no such thing as a watt amp. To determine wire size you need to know the current. Watts = Current x Voltage, so if you know the applied voltage to the load that consumes 300 watts you can get the answer. If we assume 120 volts as standard home voltage then current is 25 amps. If you had 240 volts it would be 12.5 amps. In general 14 AWG is 15 Amps 12 AWG is 20 Amps 10 AWG is 30 Amps
This is a voltage drop question. To answer this question an amperage is needed.
