bleeding Hydronic Baseboard heating system
I have just moved into an old house in New Jersey and the house has two separate heating zones: one thermostat upstairs and one thermostat downstairs. The upstairs thermostat is currently inoperative, so a PSE&G technician circumvented the problem, and now both upstairs and downstairs are being regulated by the downstairs thermostat. The problem is there is no heat getting to the upstairs baseboard fin-heaters; the PSE&G tech said there is probably air in the line, and so bleeding is required. I tried to bleed the line as he had suggested but after I open the 30psi valve release, the hose I connected to the upstairs return-line drain faucet is NOT where the water comes out, but instead the water is being discharged out the 'emergency' valve which has no threaded line for a hose connection; and anyway I think the water is not being 'pushed' upstairs and back down the upstairs drain, but just to the emergency valve. Could someone help me, we're freezing upstairs?

I'm not sure I've followed you exactly - but each of the baseboard units should have a bleeder valve. Bleed each until water comes out.
Are you sure the zone valve for the upstairs is opening when there is a call for heat? You say that the upstairs thermostat was inoperative. Are sure it wasn't the zone valve, not the thermostat?
