Oh, and they keep reminding me that it's a furnace, not a heater

Something I didn’t know: The inner workings of our new furnace is coated with peanut oil to keep them fresh (and, presumably, nutty) until installation, a point that seems important to disclose before mounting the thing in the utility room. Fortunately, now that aerosolized peanut essence is coursing through the ducts, no one here at the house is allergic to nuts.
