Higher rpms, the water pump spins faster and the engine creates more heat.
So I would guess it's pushing more hot coolant through the heater core, but you've still got air in there blocking the flow of coolant.

I want YOU to do it!
I gave you directions, all you need is a pair of pliers to undo the clamp. Just do it...verify the air is out of there before beating your head against a wall looking for something else.
The only other thing I can think of (assuming your coolant gauge reads normal) is the flap that controls the mixing of hot and cold air. There is no reason this would magically fail right after a timing belt job. Very unlikely cause of your problem. So you're back at bleeding the system of air. It's SOOOO EASY to verify yourself that the air is out of the heater core. Why take your mechanic's word for it...just do it so you can see if with your own eyes. You're wasting more time sitting at the keyboard typing.

RKA - I'm still having problems
RKA - you gave me similar advice three weeks ago. I've since bled the heater core, I think.
My heater core outlet hose still has the bleed hole. I parked the car on a level surface. I loosened the clamp and slid the hose out so air could exit the hole. Then I started the car, and filled the system, and ran a high idle until fluid came out the hole. Then I pushed the hose back on and tightened the clamp.
Did I miss anything? Just curious, because the car still doesn't make much heat. I removed the glovebox, and can see the solenoid moving the arm to the extreme open and closed positions.
The air gets a little warm, but doesn't seem to be capturing enough calories of heat to warm the air stream. If I turn off the blower, after a minute or two the heater core gets hot enough so when I turn on the blower, it's first hot, but rapidly cools. In defrost mode, the heater core can't keep up with the A/C.
Could it be the thermostat? I suspect it, however, the temperature gauge on the dash stays solidly in the middle.
Any ideas?
