I'll start with the basics. Roughly 1800 sq ft home external chimney all the way in one end of the house. Fisher fireplace insert installed in the dining area in that fireplace. Bedrooms down the hall in the other end of the house. Insert is primary heat source but I am plagued by cold master bathroom and kinda cool bedroom. floor plan wasnt intended for the pirmary heat source to come from the fireplace. every year i experiment with different combinations of ceiing fans and box fans in the hallway to move the cool air to the warm roomand with much frustration. So i have always thought i would add an in the attic insulated duct with an inline fan to pull warm air from ceiling in dining room (which has plenty) back to the cooler rooms in the house. But recently i ve been seeing advertisements for these high efficiency Quartz and what not heaters. So i get to thinking i migh could run one of those about as cheap as i could run a ducted fan. So with a bit of shopping around i found this heater called envi. it fits on the wall uses plug in or may be hard wired claims its only 475 watts and will heat 150 square feet. Im kinda skeptical but theyre pretty cheap and easy if they wouldnt use too much power I could see me using two of them. But if anyone has used heard of or even knows someone who thinks they know. please have at it.
