Well, it ran until about 1:45 am. I’m not sure I ever actually slept; if I did it was a light sleep as I listened for any changes in the rumble of the heater and the click of the fuel pump. I’m pretty sure I woke up immediately when it shut down. I turned off the system, lay there for a while, remembered that I had seen another fuel line valve for the furnace (I think it was just off because we happened to be pulling fuel from the port tank; this was the one for the starboard tank). I figured it couldn’t hurt to go try turning them both on, so I did that and the heater ran until about 4:00 am. I decided to bag it for the night and wait until morning.
It fired right up again this morning and we’re up to 55 degrees. But why does it keep shutting down after a few hours? T, I may give you a holler this evening if you’ll be around. I’m kinda out of ideas, although I will go look for another filter, per Rob’s suggestion and I will revisit all of your notes about possible alternate causes.
Is this starting to seem like the “Hurricane Heater blog” to anyone else? God knows my life is feeling like it revolves around the presence or absence of heat. I escape to work every day where the world is warm and normal. Then back to the challenges of boat living at night. Still, I do love being on the water.
