A good outdoor heater can lengthen the usable season of alfresco rooms; a great one will also add flare to an exterior design. Alpina’s LightFire Patio Heater’s (pictured) adjustable flame and striking LED-lit base lends itself nicely to a modern outdoor aesthetic ($2,858, alpina-heaters.com). Lynx’s mushroom-shaped Infrared Outdoor Patio Heater offers an industrial feel to large seating areas ($1,439; lynxprofessionalgrills.com). An optional side shelf on Napoleon Gourmet Grills’ Bellagio heater provides a place to warm appetizers or a hot drink ($749; napoleongrills.com). Blue Rhino’s rustic-style heaters, which are designed to look like indoor floor and table lamps, introduce a cozy interior touch to an outdoor space (from $150; bluerhino.com). The whisper-quiet Hanging Halogen Heater from Well Traveled Living dangles over an outdoor table, warming dinner guests ($140, patiomarket.com). Kindle Living’s made-to-order Allison lamp manages to look both classic and contemporary, illuminating and warming nights spend outside ($2,450; kindleliving.com).
