heat blower/vents/returns on the floor blows cold

Hi There: My questions is; when we turn the heat on, the vent on the floor under the sink blows cold air as does the vents under the bed? It blows cold whether I use the gas or electric setting. The bathroom vent in the back blows warm and the vent under the refrigerator blows warm. Any ideas?

Show us photo of AquaHot control panel. Feel the two lines downstream of check valves to see if warm, maybe a stuck check valve, tap with hammer. Feel both zone pumps, are they both running? How is diesel running? Shutting off early? Greg

I think Greg is right. You likely have a stuck check valve. I have used the plastic handle of a screw driver to tap the valve.

Good luck.
