Deck heaters are devices used to warm outdoor surfaces, such as decks and patios, during cold weather. They help prevent ice and snow accumulation, making these areas safer for walking and reducing the risk of slips and falls. Deck heaters can be electric or hydronic, using heated water to provide warmth. These heaters are often installed beneath the deck surface or as part of a heating system. They are particularly useful in regions with harsh winters, allowing homeowners to enjoy their outdoor spaces year-round. Proper installation and maintenance are essential for optimal performance and safety.
