Its the worst inferred heater ever. I changed the bulds 3 times in two years. They claimed 5 years on the bulbs. And then to get the warranty to back them was a nightmare. My friends had the same one and it started a fire. I threw it in the trash and got a 100 dollar life lux one from menards. It actually heats the house up and It kicks the edenpure butt in every way possible
