There is a lot of cold weather in places that don't usually get as cold as it is this winter, For you people, and anybody else that don't usually use(or think about) a second heat source should look into quartz infared heaters, they are economical to run,very safe and the heat it puts off doesn't remove the moisture from the air.I use the Eden Pure 1500 watt brand,there are other brands and wattage's on the market. Just a little info for people who might need extra heat this winter. Len
