I have what I think is an airlock in my hotwater baseboard heater. My house has 3 zones. 1.) The basement 2.) Both bedrooms and bathroom 3.) living room and kitchen. I have heat everywhere except the bathroom. The layout on the back of the house goes bedroom... bathroom... bedroom. Both bedrooms have heat but the bathroom doesn't.
Can somebody please help me figure out what's going on. I think its airlocked and if so how do I get it unlocked?
