Are electric infrared heaters affected by wind the same way?

No, and this is one of their genuine advantages in exposed or windy outdoor spots. Electric infrared heaters like the Dr. Infrared Heater Patio have no open flame to blow out, so wind doesn't interrupt operation the way it does with propane heaters. Wind can still carry away some of the felt warmth, but the heater itself keeps running.

Does a windscreen actually help?

Yes, meaningfully. A simple windscreen, whether a purpose-built accessory or a strategically placed outdoor privacy panel, cuts direct wind exposure to the flame significantly. Positioning the heater with its back to the prevailing wind direction, even without a dedicated windscreen, also reduces flame disruption.

Patio Heater Blowing Out in Wind: Causes and Fixes

Q: Why does my patio heater's flame go out in moderate wind but not strong gusts?

This pattern often points to the thermocouple's flame sensitivity rather than the wind itself physically extinguishing the flame. Moderate, sustained wind can push the flame just enough off the thermocouple's sensing position to trigger a false shutoff, while very brief strong gusts sometimes pass before the safety system reacts. Repositioning the heater or checking the thermocouple's alignment addresses both scenarios.

If your propane patio heater keeps blowing out in wind or on breezy evenings, the cause usually comes down to placement, flame guard condition, or the thermocouple's sensitivity to draft. Here's how to diagnose and fix it.

Step-by-Step Guide

Fix 1: Reposition away from direct wind paths

Move the heater so a wall, fence, or other structure blocks the prevailing wind direction rather than placing it in an open, exposed spot. Even partial wind blocking on the upwind side meaningfully reduces flame disruption.

Fix 2: Check the flame guard or wind guard for damage

Most standing heaters include a metal wind guard around the burner. A bent, dented, or missing guard reduces its ability to shield the flame from gusts. Inspect it for damage and straighten or replace it if compromised.

Fix 3: Check thermocouple alignment

Wind can push a flame just enough off the thermocouple's sensing position to trigger a false safety shutoff, even without fully extinguishing the flame. Confirm the thermocouple sits in the correct position relative to the pilot flame per your model's manual.

Fix 4: Add a windscreen

A dedicated windscreen accessory, or a strategically placed outdoor privacy panel upwind of the heater, cuts direct wind exposure to the flame significantly and is a low-cost fix for a consistently breezy location.

Fix 5: Lower the flame setting in high wind

A flame set to maximum height is more exposed to wind disruption than a slightly lower setting. Reducing the flame height on breezy evenings, if your model allows adjustment, can improve stability at some cost to peak heat output.

Fix 6: Consider switching to electric infrared for consistently windy spots

If a specific location is reliably windy on most evenings you'd use the heater, an electric infrared model has no open flame to disrupt and simply doesn't have this failure mode. It's worth the switch for a spot where wind is a near-constant issue rather than an occasional one.

A propane patio heater that keeps blowing out on breezy evenings is one of the more frustrating problems in this category, mostly because it seems to happen at random.

It's rarely actually random. Wind exposure, flame guard condition, and thermocouple sensitivity all play a role, and most cases are fixable with placement changes or minor adjustments rather than a repair.

The fixes below move from the easiest changes, repositioning the heater, to the less common causes worth checking if the problem persists.

Start With Placement

Positioning relative to wind direction: A heater placed directly in an open wind path will struggle regardless of how well-built it is. Position it so a wall, fence, or other structure blocks the prevailing wind on the upwind side.

Wind guard condition: Most standing heaters include a metal shield around the burner specifically to reduce flame exposure to wind. Check it for dents or damage that would reduce its effectiveness.

Diagnosing Your Specific Problem

Flame goes out in moderate, steady wind: often a thermocouple sensitivity issue rather than the wind directly extinguishing the flame. Check thermocouple alignment.

Flame goes out only in strong gusts: more likely genuine flame disruption from wind force. A windscreen or repositioning against a wind-blocking structure is the more direct fix.

Problem only happens in one specific spot on the patio: the location itself is likely a wind funnel, between buildings or through a gap in fencing, for example. Moving the heater to a different spot on the same patio often resolves it entirely.

Problem happens on every breezy evening, in any spot on the patio: if wind is a near-constant issue at your location, an electric infrared heater removes the failure mode entirely since it has no open flame to disrupt.

Quick Diagnosis

Symptom	Most Likely Cause	Fix
Goes out in steady moderate wind	Thermocouple sensitivity to draft	Check thermocouple alignment
Goes out only in strong gusts	Direct flame disruption	Add a windscreen, reposition
Happens in one specific spot only	Location acts as a wind funnel	Move to a different spot on the patio
Happens on nearly every breezy evening	Location is consistently exposed	Consider an electric infrared model
Wind guard visibly bent or damaged	Reduced flame shielding	Straighten or replace the wind guard
