Riley Jake Jackson died after the fire in Ilkeston, Derbyshire, on Friday evening.
His family said in a statement: "Riley touched the lives of everyone who met him.
"Despite being born with a serious heart condition and needing surgery just after his first birthday at Glenfield Hospital, as well as dealing with multiple health conditions, he took it in his stride like the brave warrior that he is.
"Riley loved life and lived every day to the full, never letting any barriers hold him back.
"He is a superhero, and his light will always shine as brightly as his smile."
