Electric heat (by which I assume you mean a coil) is purely resistive, not inductive like the compressor motor on the air conditioner. Therefore, there is no surge.
Fans have electric motors also which are inductive, but their startup current requirements are not very great.
FYI, I have two Flagship Marine A/C units (16,500BTU and 12,000BTU). Each one is fitted with a large electric coil, which draws just over 2,000 watts. These units have been wonderful for me for the past five years, and for a couple of friends who also have them (as does the USCG and the Canadian CG).
However, they are not very quiet when on A/C. On the heat setting, they're very quiet, with just the fan running.
Also, several users have recently reported mechanical problems with them (which I haven't seen, thankfully).
