Recently had issues with furance (line to radiators to full) and needed to drain off the excess. Got leaves to where they were needed and have heat to the radiators, but I have no hot water coming to the kitchen sink, bathtub, and bathroom sink. I am on the 2nd floor and have tried opening all lines at once to draw up water from the basement through the lines to remove the air in the lines with no luck. I've done this at least 3 times now and get no water to bathroom unless I have the kitchen sink tap running (if I have it open to full force the water comes out in a trickle) and the water is completely cold. What can I do to remove the air in the lines and will removing the air start the "hot water" to flow to the upstairs? Any suggestions on what else I may need to do if the water pressure corrects itself and the water is still cold?

Wow, you have me completely confused. Are you saying that your domestic hot water is heated from the same source as your comfort heat? Give more details.
I have a feeling that I am going to learn something new here. Hope some of the other experts will jump in on this one and help you (and me)out.

Hello. The furnace does not have a water heater there is a glass vile at the front of the burner that for optimum water levels to the radiators needs to be set at the mid level of the vile. For some reason the water level went to high and I drained the water from the radiators, to the level needed. When restarting the heat furnace I then found that I had no water pressure to the plumbing to the lines for the kitchen sink, bathroom sink and shower. I have cold water pressure, and water does come out of the hot line (but it is cold) and only at a low level. The kicker as well is that for the water to come out of the tub and bathroom sink I have to have the kitchen hot faucet turned on. I believe there is air in the lines but not certain on what I need to do to bring up the pressure and to have hot water!
