400A is an absurd number. I live in the northeast have a heated pool, electric water heater, and am putting in heat pumps and it all runs off a 200A. 100A is the standard hookup in my area.

Also a propane pool heater is far cheaper then electric, converting propane to electricity is really crazy when you could just have propane heat, hot water, and pool heater.
