No it's not a walkout ,but I wish it was. window side of basement has the southern exposer so there's always plenty of light. Fireplace works nice! set it up so it can always be on , or it can operate off of the wall mounted thermostat I installed. one of those big projects thats been close to being finished for a long time. What I like is it can heat the basement to an easy 80F degrees when its -25F outside. Now I just gotta get things down there done!!!
