short burst heater?
(OP)
hey, anyone have any suggestions about how one might provide periodic short bursts of intense localised heating, with no nearby combustion, without requiring a high electrical current draw?

Lasers?
Flash lamps? ( Google "Edgerton" )
Arc lamps?
Gamma rays?
Neutrons?
It depends on what you want to heat, and what you mean by 'short' and 'intense'.

hi-temp water or oil heater ; again all depend on the temp you are trying to throw,
maybe an induction heater who knows. POST IT...

What is the basis for comparison on current draw? How much lower do you need? Even an arc welder could potentially fit the description.

I wonder whether the "flash lamp" circuitry could be revised to operate a small heater, thus limiting the sustained current draw to an acceptable level, while allowing a very high local current?
I was also wondering whether there is a chemical mixture which could be used as a small "thermal battery," allowing slow accumulation of heat (endothermic reactions) and rapid release (exothermic), over and over again, within a closed volume (skinny steel tube, perhaps)? Like these but reversible? htt

If you want more energy, you'll need to have a a long charging time to provide more energy prior to release.
You say you have airflow; how much and what is the effective HTC at 700ºF. This is lost energy that must be provided by your heater element.
While 50 gm of sodium acetate could provide up to 9000 J, it's unclear that all of it could be released within 40 s.
