Gas and Oil Home Heating Furnaces - No heat upstairs?

We recently had our bathroom remodelled. The plumber came to reconnect the basebord heater. He drained something to do with the sytem (this is what he told me), before he began. Since then our radiators upstairs have not worked it started with one and now it is all of them I keep bleeding them to no avail. Only the one in the bathroom bleeds until water drips out and then works. I have bled the others 4 or five times in the last hour the air comes out for a few seconds but then nothing. One seems to be coming to life but I can't keep taking off the covers and doing this. Do you think the plumber forgot to close a valve or something. Should I get him back out I would rather not as the contractor we dealt with was very bad and I just don't want to have to even see him again.

Thanks

???????????????????????????????????? DID he turn the auto water fill back on after he hooked it up again.Yes you have to bleed them till you get water out of them if you want heat. Is the pump running also. He did it get him back ;) ED

The plumber drain the system. Everything worked before. His work caused the problem. Call him and have him unf*&^ it.

What is the pressure and temperature and how old is the system?

Thanks for all the replies.

The system is 7 years old. And was seviced 1 month ago before the plumber messed with it. I just switched it on to 72 degrees about 40 minutes ago the bathroom basebord heater is very hot, One radiator is hot the other three are cold.

The pressure is at 160.

EdImeduc: I don't know what he did. I just remember him saying he would have to drain something so he would not burn himself!!!

cb69235:
It would be the temperature that is 160.
If the pressure were that high, I would be telling you to get out of the house and head for the hills. :eek:
You probably could cut that back to between 140 and 150 deg F.
Pressure should be about 20 to 30 psi.
If the radiator was drained completely and then refilled you may have to just be patient with the bleeding untill all the air is out.

Gregh Ok so I checked again psi is at 5 the temp has dropped to 150. How patient is patient I have been bleeding them for a couple of days is this normal?

cb69235:
The pressure is too low. It should be at least 20 psi. The lower the system pressure,the longer it will take to push the air out.
You will have a pressure regulator on the water line just before it enters the boiler piping. There will be a screw or bolt to adjust the pressure. Clockwise will raise the pressure. Try a half turn at first and then wait awhile for things to stabilize. Don't turn it too much at a time as it is easy to overshoot the pressure.
Once you get the pressure stabilized at 20 psi, bleeding the rads will be a lot quicker.
