Here is the revised list of relevant options for heating and cooling a deck: - Radiant heating (electric or gas) - Propane heaters - Roof structures for heat retention - Shade from roof structures, pavilions, and gazebos - Fans for cooling - Pergolas, umbrellas, awnings, and sails for shade - Misting systems for cooling with water mist - Material of the deck affecting heat retention (e.g., vinyl decks reflect sunlight and are cooler than composite decks) - Lighter deck board color to help with heat - Fire pits (gas-burning or wood-burning) - Chimineas (portable fire pits with a chimney) - Portable outdoor space heaters - Strip heaters (tall heaters mounted to a wall or overhang) - Tabletop heaters for localized heating - Heated decking (smaller strip heaters that heat a smaller radius) These options can enhance the enjoyment and year-round use of outdoor decks in various climates.
