E and I were away for a week and I had high hopes for the furnace to continue working during this time, especially since the high last Friday here was 23 degrees! Well we came back to this:

SAD PLANTS!!!!
Turns out the furnace at some point stopped working and I have been on a whirlwind of ups and down the entire day. Let me walk you through it:
DOWN: The furnace stopped working and it was cold and my plants are SAD!
UP: It seems likely the furnace lasted for a bit since the low recorded by my thermometer was only 28 degrees (the low outside was around 17 degrees). Also, most of my plants (minus that super sad avocado above) seemed to be alright. I suspect the furnace was fine until it ran out of oil sometime during the week I was gone.
DOWN: I’m pretty sure the furnace ran out of oil and I thought I put 5 gallons of diesel in right before we left. This will cost a fortune to heat!
UP: Wait – I go get diesel and my gas can is only 2.5 gallons! Maybe this isn’t as bad as I thought!
DOWN: I put the new 2.5 gallons of diesel in the tank and press the restart. And no heat. The furnace turns on, I can sort of hear a spraying noise, and then the safety kicks in and the whole thing shuts down. Fuck!
UP: I am determined to fix this! While looking up YouTube videos about fixing furnaces I see something about bleeding your furnace if it runs dry. This seems very likely the issue since I’m pretty positive it ran out of oil (diesel is oil minus the red dye). I gather tools and prepare for battle with this fucker:
First I forget that the heater has to be on for this to work and think that maybe there is a total clog somewhere since I have removed the entire bleeder valve and there no oil to be seen… But luckily I remember! Air and oil sputters out. I try to restart…
DOWN: It does not start. I bleed it more. More air and oil. More oil. Now just oil. A steady of oil.
UP: IT’S ALIVE!!!!
UP: 
Almost 60 degrees now (plus my really janky thermostat which definitely needs to be replaced – that’s for another time though)
