So I'm trying to figure out why they call these things 3-season rooms. They're too hot in the summer and too cold in the winter. Spring and fall are nice, though (except when it rains, but that's a different post).
This room does not have its own heating (or cooling) source, so in the winter we run a greenhouse/contractor's heater in it at night to keep the window panes from breaking (we've had that happen a few times) and the plants from dying. We don't heat it to a toasty warm human-friendly temperature--it's too expensive. When the sun comes out things warm up somewhat during the day. But at night, it's frigid without the heater running, especially when it's NINE BELOW as it is in Chicagoland this morning (is it really just the FIRST day of winter?).
That heater has been running all night and the room is still in the forties. I'm not looking forward to the next electric bill.
Oh well. We may not have much use for this room right now. But my 5-year-old sure has fun breaking off the icicles and turning them into swords!
