@ShadyGreenThumb do you find much fluctuation in the temperature? Last year I bought one of those "oil" heaters (has oil inside that heats up) - it fluctuates 4-6 degrees before it warms again. No fan so similar to the Presto in that regard - mine kind of looks like an old-fashioned radiator. It has worked pretty good - but I've got an eye out for something that might be a little more "even" heating - wish it has a thermostat !
