We built these electric patio heaters for one reason: to make open-air spaces feel cozy, no matter the weather. The magic happens with a high-output infrared lamp—packed with power, focused in a small footprint, and tough enough to shrug off rain, wind, and whatever else the sky throws at it. Here’s the thing about how it works. It plugs into standard mains voltage (220–240V) and draws 1.5–2.5kW. That power turns straight into radiant heat—no waiting around for air to warm up. So even when the breeze picks up, you still feel that instant, comforting warmth. The tube length is chosen to shape the heat just right: longer for a wider spread, shorter for a tighter, more intense beam. We chose halogen-filled quartz tubes for a reason. Quartz handles the searing filament temps and won’t crack when things heat up or cool down quickly. The halogen gas keeps the output steady over time by slowing filament evaporation, so the lamp stays bright longer and avoids that annoying blackening. And the R7s base? It locks in clean, solid contact, lines up perfectly, and makes replacement a breeze—especially in outdoor fixtures. The whole lamp and electrical setup live inside a waterproof housing rated to IP55 or better, so water stays out and shorts stay out. Outdoor patio heaters have to earn their keep in the real world—rain, spray, dust, the whole deal. That waterproof build keeps the guts dry, so the heat keeps coming without the drama. Yes, it’s powerful, so you’ll want to size the circuit properly and give it some breathing room. Get that right, and what you get is a rugged, dependable heat source that installs quickly and keeps running with hardly any fuss.
