Re: Issues with Heating in Annapolis, MD
The lack of discharge water supports Jeff's conclusion of a blockage. I'd get a couple of ceramic heaters to keep heat in the boat while you're working on the system and prevent further freezing. I'm also concerned about the pump, I'd shut the system down until you clear the obstruction and determine that the pump is working. But you'll need to work quickly in these temps.
