Let's tell the truth, we buy a gas stove to have it in a specific space and not in a palace or a house with poor windows, and it depends on what setting we have it on, 1,2,3??? Personally, in a ground floor with old wooden windows, it doesn't heat up the whole house but it makes a difference if I don't turn it on. Also, for those who say it smells good, they should know that the hose has an expiration date and it is stated on it, over time it wears out, and in all open-type heating devices such as gas stoves, fireplace, and kerosene lamp, we either have a permanent ventilation filter or we frequently renew the atmosphere through a window.
