If you really think there's a flush draw out there and want this pot right now, the correct play is probably to underbet the flop and overbet the turn. The flop underbet is to get a raise out of someone and try to fold the draw that way (of course, you want to be raised anyway), but it also keeps the pot small on the turn so you can push on a non-heart.

Honestly, though, I'd be too focused on how to get the most chips into that pot to worry too much about the draw. If they want to chase, good for them, because if I triple up here I will almost certainly take at least 2nd and I sure like the odds.
