Technical Deep-Dive: Power, Voltage, and Geometry
We build this patio heater around a high-intensity halogen infrared lamp to deliver localized, directional heat. Typical configurations run 2500W to 3000W at 230V/240V or 400V, letting you spec the unit to match available electrical drops and thermal load. The tube length is usually around 300mm, a compact footprint that concentrates wattage into a small radiating surface. That geometry produces high heat density, so you get fast warm-up and strong line-of-sight output.
Material & Design: Halogen, Coating, and R7s Connector
The tube uses a quartz envelope with a halogen fill. Halogen chemistry keeps the filament stable at high temperature, which helps maintain output over the lamp life and reduces blackening compared to standard incandescent. The interior is coated to manage the infrared spectrum, pushing energy into the 2–3 micron band for efficient absorption by people and materials. Termination is R7s—a double-ended linear connector that seats quickly and carries high current without needing extra hardware.
Application & Benefits: Outdoor Comfort with Industrial Control
In patio heating, you need heat where it’s needed, not in the air above. The shortwave infrared profile heats surfaces and occupants directly, cutting wasted energy. The R7s base simplifies installation and replacement, keeping maintenance downtime short. Trade-off: the concentrated heat demands proper mounting clearance and ventilation. Plan for airflow and thermal separation so the heater runs hard without overheating nearby components.
