No matter what type of heating (or cooling) you have, I think the cheapest and fastest way to get your bills down is still to buy an air circulator, as pictured. This is the ‘Vornado’, one of the best. Because heat and cold left to themselves sit at opposite vertical ends of a room (top and bottom, respectively), without air circulation you’re throwing a lot of energy at heating or cooling only about half the room, and with heating often the half above your head. Have had one of these running gently in my lounge room this week. Have been able to turn down the thermostat 2-3 degrees and still feel much warmer than I did before. They’re a fan, but a very special type, a vortex fan, that creates vortices. These then enter the room and mix the air continuously. Even laying on the ground I now feel the warmth.
