Have a two story house. Insert in family room on 1st floor. Can get most upstairs rooms about 66...which is fine for my wife and I. We usually keep my 2 year old daughters room door closed (2nd floor) or else she will wake up as we are walking by or hear us and want to get up. When we do this her room gets quite cold. My question: is it ok for me to put a oil filled radiator type space heater in her room? Anyone see any contraindication?
