How to Choose the Best Outdoor Infrared Patio Heater

September 3, 2026

Why Infrared Heat is the Smart Choice for Outdoor Spaces

Unlike forced-air or convection heaters that warm the air (which promptly blows away), infrared heaters emit radiant heat that warms people and objects directly — just like the sun. That makes them dramatically more efficient outdoors, where wind would otherwise render a traditional heater useless. If you've ever sat near a patio heater that barely made a difference on a breezy evening, you've experienced the problem infrared solves.

Electric vs. Gas Infrared: Which Is Right for You?

Electric infrared heaters (like the Dimplex DIR and DSH series) plug into standard or dedicated circuits, produce zero emissions, require almost no maintenance, and can be used indoors or outdoors. They're the right choice if you want instant, controllable heat without running a gas line.

Gas infrared heaters (like the Dimplex DGR series) run on natural gas or propane and produce more raw BTUs — useful for very large, open commercial patios. They require proper ventilation and a gas connection, so they're better suited to permanent outdoor installations with existing gas infrastructure.

For most residential patios, decks, and covered outdoor rooms, electric infrared is the practical winner: no gas line, no pilot light, no carbon monoxide risk, and usable indoors too.

How Much Wattage Do You Need?

A common rule of thumb: you need roughly 10 watts per square foot of space for comfortable outdoor heating in mild climates, and up to 15W/sq ft in cooler regions.

Small patio (50–100 sq ft): 1500W is sufficient — covers a cozy seating area or a covered entryway.
Medium patio (100–150 sq ft): 1800W–2200W hits the sweet spot for a dining table and chairs.
Large patio or open deck (150–250 sq ft): Step up to 3000W, or use multiple units for even coverage.

The Dimplex DIR 1500W (120V) is unique in that it plugs into a standard household outlet — no electrician needed. For higher wattages, a dedicated 240V circuit is required, which is a one-time installation that pays for itself in years of reliable heating.

Mounting Options: Wall, Ceiling, or Floor?

Where and how you mount your heater affects both coverage and aesthetics. Here's what to know:

Wall-mounted (fixed angle): Best for covered patios where you want the heat directed at a specific seating zone. The Dimplex DIR series mounts at a fixed downward angle for efficient zone heating.
Ceiling-mounted: Ideal for pergolas or covered outdoor rooms. The Dimplex DSH Ceiling Mount Bracket makes installation straightforward for the DSH series.
Floor stand: The most flexible option — position it wherever heat is needed and move it seasonally. The Dimplex DSH Permanent Floor Stand keeps it stable without wall or ceiling penetrations.
Plug-in portable: The Dimplex DIR Plug-In 1500W is the easiest entry point — plug it in, point it at your seating area, done.

Indoor/Outdoor Rating: Why It Matters

Not all heaters are rated for outdoor use. Look for an IP (Ingress Protection) rating — the higher the number, the more protection against moisture and dust. The full Dimplex DIR and DSH series carry an IP54 rating (splash-proof from any direction), making them appropriate for covered outdoor spaces like porches, pergolas, and patios. They should not be exposed to direct rain or submerged, but standard outdoor conditions are no problem.
