Not getting hot water passing through baseboard pipe

Foodstuffs

Hello, I had my 2nd floor baseboard heating system not getting hot water passing and I had water pump and air tank replaced but still no water going upstairs. 

neilc

that pressure might be a little low,
do you know how to add to your boiler?
post a general picture at the boiler, floor to ceiling,
show the circ(s), tank, and any valves,
one or 2 angles,

and what's upstairs for rads?
upright cast iron, or baseboard?
again, a picture,
and any air valves up there?

how many thermostats?

The technician who replaced the pump and tank didn't finish their job. Most likely an airlock, but they should be coming back to take care of it for free.
