Customer Reviews

Best heaters I've owned.
Review by Domenick

I've been using Mr Heater heaters for years. I currently own five. This particular heater costs less than the part that I needed for my old heater plus it heats the room twice as fast with half the gas. All of my heaters work fine above 7500 ft. I recently had a minor problem with one of my heaters and I contacted Mr Heater. Three days later I had a new heater on my front porch.
