The Heat Surge was just what I needed. I ordered the Heat Surge directly from Heat Surge and after ordering THEN I read reviews. There were so many wonderful reviews and a few negative reviews but by reading just a few negative reviews it left me feeling like I made a wrong choice(left me feeling buyers remorse). I focused on the few negative as opposed to the many wonderful reviews. I received my Heat Surge plugged it in and was SO PLEASED with the entire unit. BEAUTIFUL. I have a large home and know that the unit wasn't intended to heat the entire home so wasn't sure how much it would really heat. I kept it set on low. In the first hour and a half it raised the thermostat by 3 degrees, after 2 and a half hours by 5 degrees still set on low. The temp kept creeping up. I only left it on for an entire 5 hours then shut the heat off and left only the flames running(which makes for beautiful ambiance). My home was comfortable(to me). I have a very well insulated home so maybe that helped with some of it. Regardless the unit worked wonderfully, quietly and is truly beautiful! My Aunt has one, my parents are getting one and they are sticklers(very picky)people on most everything. They actually liked it too. Glad I got it and am sorry I worried myself sick on it and second guessed my ordering one. So many people aren't reading that it isn't meant to heat the entire home and complain about the size??? The measurments are all listed. The unit is not small. It is the size of a regular gas insert based off the one I have in my home and other inserts I have seen & I believe the heat surge is FAR more eye appealing. By no means did I get it to heat my entire home but it is doing a really good job of it. I received more than I expected it to be. I am VERY pleased with this unit and everyone who has seen it has been pleasantly surprised of it's looks and the warmth it was producing. I have'nt used my central heating since receiving the heat surge at the beginging of Oct. Don't know if this is typical but it's what I've experienced. I LOVE IT!
