no heat on 2nd floor.

hello all and thanks for the help. i have no heat on the 2nd floor. the boiler provides heat for the 1st and 2nd floor. i went and looked at the water pump for the 2nd floor and it is running but it seems like no water is being moved. i wonder if i need to bleed this system or maybe the impeller is shot? a bit of info on my heating system. it is a oil fired single boiler system. it uses hot water baseboard heating. the 2nd floor uses some of that plastic coated copper bendable tubing the rest of the house looks to be iron pipe and copper tubing. thanks again for your help.

What is the system pressure? Photos of your system would be helpful.

Yes...... very little pressure.
You need to add water to the boiler. You need +15 psi to get the water to the second floor.

The yellow arrow is pointed to the water pressure fill valve. It should be around 15psi. It may be bad or the main fill valve is off. You can lift the handle to add water to the boiler. Don't add water to a hot boiler. Let it cool down first.

I'm curious as to why there are two water lines coming off the regulator. There should be one line from the regulator to the boiler.

took a look at the lines on the regulator. one goes in to the boiler and the other comes from a pressure release valve. i got the pressure up to about 18 psi. still no heat on 2nd floor. i think the regulator was just a bit stuck. i gave it a quick pulse then it hissed for a bit and stopped. i take it the 2 pumps pull water and not push it? the arrows are pointing down to the boiler. always thought they pushed the water. btw if you look at the wiring i think someone goofed. i don't think there is no way for the 2nd zone to turn on the furnace.

Hi, have you ever had heat on the 2nd floor? Is that circulator running? Can you identify where the thermostat wire goes to at the boiler?

heat has been working on the 2nd floor. the circulator is running and the motor gets very hot on that one. i know the thermostat is working as i hear it click the relay and the pump starts. i think the blade might be messed up? i do get pressurized water from the faucet above the pump. only thing i can think might be the problem is the impler on the pump has fallen off or the blades are shot?

quick update. the boiler is at about 30psi now. when i turn on the pump i hear water start to flow on the 2nd floor but still no heat. as far as i know there is no air release valve on the 2nd floor so i don't know how air would get out. does it need to get out? thanks for the help guys.

another update. i got most of the air and gunk out of the 2nd floor system by closing the valve just above the 2nd water pump and letting water and air out in to a bucket. when the pump kicks on for the 2nd floor it is much more quite. i then noticed there ware nothing stopping the 2nd floor from pulling water backwards through the 1st floor. in the pictures you can see what i mean. no check valve on the 1st floor circuit. when i turn on the 1st and 2nd floor pumps at the same time i get heat on the 2nd floor. also i found that the air release valve was totally shut. would love some insight from some one who knows this stuff. thanks.

more boiler pics
