The Varnado space heater is the best in the business! This is the third tornado heater that I bought designed in Kansas and shipped out within five days. I received it easy to use that has low heat high heat and fan settings comes with a built-in remote in the shipping container. I choose low heat when it's just need a little heating and it has a timer shut off like I can set the heater for two or three hours at night and then it goes off looks really sharp from the first ones. I bought totally stainless steel on the outside with a black top black control area highly recommend for any size room large living room medium bedroom right now I'm using two one in the living room for additional heat and the Texas winter and one in the main bedroom that I use almost a year round my wife likes it warmer. If you control the use, the energy cost is not significant tornado this is the third tornado heater that I bought designed in Kansas and shipped out within five days.
