I actually had let my boiler burn out and removed all the live smoldering ashes and embers during that warm weather stretch when the gasket started to leak. When I got home from work around 7pm last Monday I saw the colder temps coming later in the week so I added enough water to fill it back up to normal level and started up another fire. The internal water temp was at 40 degrees at start up and it took about 3 hours to get it back up to 160 but with the week of water lost I got air in my lines so I had an air lock develop within the lines. So at 11:30 before bed I went out and used a water hose and connected it to a valve in back of the boiler and flooded the lines to push the air back into the tank. I let it gurgle and bubble we’ll before reconnecting the line. There has to be a much easier or better way to do this which I’ll be looking at during the off season. Anyway, the water temp are back up to snuff and I’ve been running back on the boiler for heat and house has been nice and toasty ever since. It was nice not having to fill up twice a day for a week while it lasted and can’t wait till I can give it a rest for the summer spell which should be just around the corner.....I hope! Lol
