Default Heat stretching methods
Always been more of a balloon guy but I'm trying out inflatables now. I want to try heatstretching some but I don't really have enough space to use boiling water. With balloons I can toss them in the oven while deflated at 290F for ten minutes, has anyone tried anything similar with inflatables?

I've heat stretched 48inch beach balls in the shower.... you just keep rotating the ball under the stream of hot water (else you'll end up with an egg shaped ball) and keep adding air frequently so there's no ripples appearing along the seams and the ball will stretch. I usually stop at about 72inches though as the vinyl is very thin by then and is just on the cusp of 'pin holing'.

I'd advise against putting them in the oven, they could just melt together.
Personally I've only ever used boiling water over the bath or a hairdryer.

I've tried both, hot water and air. Water takes longer, uses up more space, etc, but it stretches the inflatable a lot nicer. I've also tried stretching a small beachball with a hairdryer while sitting on top of it (it wouldn't stretch without any pressure being applied) but that just ended up making a bulge grow right between my legs (on the beachball, mind you) and ultimately popping it. It was a fun experience, but if you're looking to keep your inflatables after stretching, water is the way to go in my opinion.

Two more methods I can think of.

One would be to use "natrual" resourses by doing the stretching in the sun. The sunlight heats up the inflatable and makes it quite a lot softer. Add more air every now and then for a nice heatstretch.

Or the, in my oppinion, best and easiest way to reach the maximus size is to use stream.

As mantioned befor the hairdryer is quite usefull as well, but a little tricky

This guy knows how to do it right:
