This is finally the time of year where we start thinking about keeping the place warm. Life down in the desert Southwest is usually spent trying to cool off. Yet each winter the desert gets cold as the sun drops below the horizon. We have a room that was added on to the house years ago. It is connected to the central heating and cooling system, but the room still tends to be closer to the outside temperature. We already have a wall cooling unit there. This time of year I wish we had a wall heating unit too, maybe one of those gas infrared heaters. Those units look like just the thing to heat our cold room.
