Covered and uncovered spaces can be heated with outdoor heaters. Ventilation is needed for gas patio heaters, while electric patio heaters can be used indoors and outdoors. Even open yard spaces can be heated. Patio heaters provide predominantly radiant heat and do not greatly affect the air temperature. Rather, they warm people, furniture, walls, decks, patios, lawns and floors. Patio heaters can be used in almost any outdoor space, and can enhance your and your guests’ enjoyment of your home.
