You don't buy econo heat and expect first-class warmth.
Listen, bub. It's really no big secret; the big wigs in the heat industry don't care about you. You don't buy this Econo Wall Heater, there are 10 people in line behind you, waiting for the same unit.
That's why we can get away with cramming these 23" x 23" x 3/8" wall-mounted heaters into 23.5" x 23.5" x 3/4 spaces. You want extra sweating room, pay for the upgrade. The goal was to be warm, right? YOU'RE WELCOME.
Oh, and here's the kicker: We can delay, cancel or reroute your heat flow at any time for any reason whatsoever with zero apologies or explanation. And if it just so happens that the turd in the apartment behind you decides to knee you in the back every time you try mounting your Econo Heater, tough titty, kitty.
Heat is a privilege, not a right.
