View Full Version : Hot water baseboard bleeding

I have hot water baseboard heat. Every time the circulator comes on it sounds like a waterfall. How can I bleed this system. I do not have bleeder vales on each radiator, but I have a drain valve and shut off for each circuit. Is there a way?

Thanks

I have a similar setup, in my new house. If possible follow the following, turn off emergency switch to boiler electrical circuit, close the valve entering and the valve exiting the boiler. Open the cold water feed to the system (hopefully on the "radiator" side of the input and output boiler valves) and open the bleeder for the zone to bleed. Open each of the zone valves, one at a time, allowing cold water to circulate from the cold water feed through the baseboards and out the bleeder.
