Our downstairs gets cold in the winter due to the fact that we have a 3 season room that is mostly glass and not insulated as well as it could be.  We bought this heater to warm up the area and to avoid making our central heat work overtime.  It has worked out fabulously!  We also move it outside to our patio area that has an electric awning with a drop down front.  This heater keeps the whole outside patio warm! This heater is extremely well made and very easy to put together.  The parts are of industrial quality.  We couldn't be happier with our purchase.
