White Electric Patio Heaters

Most electric patio heaters are capable of heating areas between 1,500 to 2,000 square feet, depending on the model, wattage, and placement. Always check the manufacturer's specifications to ensure the heater matches your desired coverage area.

Expert Tip: Manufacturers' square footage claims assume ideal conditions (no wind, 50°F ambient temperature). For accurate sizing, subtract 25% coverage in windy areas or add 500W for ceilings over 9 feet. Infrared heaters perform better in drafts than convection models.

Gas or electric permanent-install heaters offer the best heating for patios, providing consistent warmth for larger areas. For ease of use and cleaner energy, electric patio heaters are a top choice—especially models with radiant or infrared heat.

Expert Tip: Permanent hardwired heaters (240V) deliver 2–3 times more heat than plug-in (120V) models. For covered patios, ceiling-mounted units with directional louvers prevent heat loss better than freestanding options.

Radiant heaters typically use as much or less electricity compared to other types of heating systems. They are energy-efficient because they heat people and objects directly rather than warming the air, which reduces energy loss in outdoor environments.

Expert Tip: Infrared heaters consume less power because they don't need to preheat air. A 1500W infrared model can feel as warm as a 2000W convection heater when positioned correctly (angled at seating areas, 7–8 feet high).

Infrared patio heaters are ideal for porches. They deliver direct heat without requiring fully enclosed spaces, making them perfect for semi-outdoor areas. Wall-mounted or freestanding models work well depending on your layout.

Expert Tip: For screened porches, wall-mounted heaters with IP65 ratings resist moisture damage. Choose models with adjustable tilt (minimum 15°)—this focuses heat where needed instead of wasting energy on unused space.

Electric patio heaters vary in price, typically ranging from $150 to $1,200 based on size, design, and heat output. Wall-mounted or ceiling-mounted options may cost more due to installation requirements, while portable models are generally more affordable.

Expert Tip: Commercial-grade heaters cost more upfront but can last 8–10 years versus 3–4 years for many residential models. Look for high-quality heating elements and corrosion-resistant housings, especially in coastal climates.

Outdoor propane patio heaters are typically rated in BTUs, while electric models are rated in watts. Many freestanding propane heaters fall around 40,000 BTUs for general use, whereas a common electric patio heater outputs about 1,500–2,000 watts (roughly 5,000–6,800 BTU equivalent) for a focused seating area.

Expert Tip: For electric heaters, focus on wattage and placement rather than BTU numbers. Check the manufacturer’s recommended coverage and pair multiple smaller units rather than one oversized unit for more even heat.

Not all patio heaters are designed to withstand rain. Look for models with a weatherproof or waterproof rating, especially if you plan to leave them outdoors permanently. Covers can help extend the life of your unit.

Expert Tip: Even “weatherproof” heaters can fail if water pools on electrical connections. Install models with downward-facing ports and use protective covers or dielectric grease on plugs if they’re kept outside year-round.

Place patio heaters in open, ventilated areas with adequate clearance from ceilings, walls, and furniture. Wall-mounted models are best for small patios, while freestanding heaters offer flexibility for larger layouts.

Expert Tip: Heaters work best when placed upwind of seating areas. For rectangular patios, position two 1200W heaters at opposite corners (angled inward) instead of one central 2400W unit to reduce cold spots.

Electric heaters are easier to install, require less maintenance, and are more environmentally friendly, especially in covered or partially enclosed spaces. Propane heaters offer powerful heat and are highly portable, making them ideal for open-air patios without electrical access.

Expert Tip: Propane often costs 2–3 times more per hour to run than electric but works during power outages and in locations without wiring. For frequent, everyday use, electric heaters usually win on long-term cost and convenience; propane is best for occasional, high-output heating or fully open spaces.
