air trapped in boiler making noise


If the air is in the boiler itself you can't vent it through the pressure relief valve on the side. If the air is in the loop (baseboard or radiators) then you should go to the highest point in he loop & bleed the air out using the bleeder valves on he baseboard or radiator. You need to follow the pipes & see where they turn colder & that's generally where the air is.

there is a problem with my heater i am not getting no vacum has new water pump and new thermostat in it and all and everything else is working except the the heat all it does it blows cold air please


Have you checked for any air locked in system?If any air is trapped in system you will not get heat through.Bleed it or open rad cap when is cold and put a container under neath to catch over flow.Start car, turn on heater fan to full,and set temp. to Maximum.After car warms up watch for bubbles coming out from the radiator cap opening.

MY APARTMENT HAS ELECTRIC WATER BASEBOARD HEATING SYSTEM, I found out the heat cannot be turned off even I disconnect the honeywell thermostats (only one on the wall for the whole unit - living room and 2 bedrooms), and I even turned off the electric supply in the fuse box, but heat keep coming out, I have to leave window opens to ventilate hot air. No hot water tank in the unit, it is coming from the building's central boiler. What should I do to gets the heating baseboard turn off?


Okay couple questions here because either you have hot water baseboards or you have electric baseboard heaters.
- if the system is a hydronic baseboard heater fed form main boiler, usually this means your space heat is controlled by a zone valve which the zone valve is controlled by your thermostat.
-if you find the zone is controlled by a zone valve than it is possible the zone valve is defective causing hot water to bleed past the zone valve even though your t-stat is telling it to close.
- first find out what excatly the baseboard is heated by either water or electricity
-next personal message me and I can walk you through it

One zone not working; another is partly working


i would check my water pressure on boiler sounds like lack of pressure or air in system they can be related. if you have bleeder on baseboard try to bleed.

three of four zones, baseboard heat, warm house, why not fourth


Go to the last heater in the zone and look for a bleed off valve so you can get the air out of the system. you may have to bleed it off several times as the air works itself thru the system. usually there is a automatic air vent on the very highest point that the system has. Let me know if this helps and have a Merry Christmas
