3♥ is forcing because that's the default meaning, and the original poster would have told us if it wasn't.
The 3NT says that he wants to try to take nine tricks without a trump suit.
4♦ shows diamonds with longer clubs, and a reason to bid - almost certainly 4-6 or longer.

It seems like there should be a way to show a good raise to 4H since it is an extremely important hand type, and because the opps are presumably done bidding, and because we are in a force (giving us pass and X as available options).
That said, I don't have one.
I agree with both of these posts.
You might like to think that partner can pass 3S with a 'good' 4H bid, and only bid on a minimum, but partner will always want to show heart support as soon as possible if he has it because the auction may go wrong later. For example, 1C 2S 3H 3S P P 4D P ? now 4H just sounds as if it is giving preference on a minimum hand with a doubleton heart, but opener doesn't want to jump with a non-minimum because responder might be quite weak in high cards.
I'd rather give up the natural 4D bid and use that as a good 4H bid than give up a natural 3NT.
How about: 4D = good heart raise, double = extra values with 4+ diamonds and short hearts (easily passable), 4NT = 5-6 minors (4D then 4NT to ask for heart keycards) ?
