But it's one hour? What did you expect to happen? A 24 hour work-day? Or an entire work-week without resting?
There _must_ be a limit. Should it have been more then 1 hour? Maybe... But I don't think so.
Must be a limit? Why?
In LotR, the heroes fought for an entire day at the fortress.
The system as it is allows you to run around 3-4 encounters - even if one or two of them are very hard encounters that require you to expend dailies. Each of these encounters will be challenging, because your in-encounter resources (encounter powers, total healing surge to be triggered per encounter - not total healing surges per day) must be managed to beat it.
The 3E approach was 3-4 encounters per day, but only the last of them would really be exciting because now you'll see if your managed your resources well enough. Or just have one very challenging encounter that requires you to go "nova"... Either way, only one encounter gets a fair chance to be a real nail-biter.
I pick 4 exciting encounters per day over 1 exciting encounter per day.
The question might: Should it have been, say... 8? Could it have been 8? Should it have been any number I like? Could it be any number I like? What are the repercussions of this?

For people that need "more" encounters per day, the easiest way to do it is just giving extra surges. Or let characters regain healing surges on milestones, in addition to action points. (And possibly a daily power).
A more complex approach might be to create some healing rituals, whose cost increase with the expected "wealth level" of the PCs.
I just find it boring to do (in our group, 4-7 encounters per day so far) and by 9 AM, the PCs are sitting around like a bunch of mopes.
I find it exciting to explore, do combat, find stuff, etc.
Sitting and waiting for Healing Surges to recover, even if the 23 hours can go by in a moment of real time, just jars me out of character. It's like watching a movie and suddenly mid-excitement, realizing that you are in a theater because the movie had a jarring moment. It takes me straight out of the immersion of the activity.
I did send an Email to our DM asking if we could double, triple, or even quadruple healing surges.
I have no problem with PCs running out of dailies and stopping because the players control that.
I have a problem with healing surges because that is mostly out of the control of the players.
Plus, since Healing Surges is a regain of will (or fatigue or luck or whatever) and not real damage, having 6 or having 50 is irrelevant.
These are heroes, not green grocers. Let them be heroes. Let them push the limits.
This "sorry, but you have no more luck for today" is pretty lame. IMO.
