We have been using this heater for over 5 years now in the very cold Minnesota winters. In fact the furnace went out in the house during record breaking cold and we were unable to get it fixed for 3 days so we had to turn to electric heaters, we used 3 heaters in our 2 bedroom home to get us through some very cold times, of the 3 heaters we used this model was by far the best! There is something about radiated heat that is much more sufficient for maintaning a temperature than a constant blowing heat. The temperature in the house stayed at an amazing 72 degrees and I was positive that our electric bill was going to be through the roof but I was shocked to see it was actually less than the previous month! We kept this radiating heater in the living room and had 2 small blowing heaters pointing into bedrooms, at night we turned off the blowing heaters and only used the radiating heater in our bedroom and the children hopped into bed with us. I can say with 3 nights of record breaking below 0 temperatures it really held up and after 5 years I still have no issue with this product.
