How to Choose Outdoor Heaters — Complete Buying Guide
Everything you need to know before buying outdoor heaters. Expert advice on what to look for, key features explained and top picks updated weekly.
Outdoor heaters split into a few genuinely different purchases: a cheap electric tabletop unit, a propane freestanding heater that covers a whole patio, a premium wall-mounted infrared fixture, or a fire pit that trades pure heating power for ambiance. Fuel type and heat output matter, but there's a bigger factor the spec sheet won't tell you about, covered below. You can check current prices across everything mentioned here on our outdoor heaters price tracker.
What you're actually choosing
| Decides | Options | What it actually changes |
|---|---|---|
| Fuel type | Electric / Gas (propane) / Bioethanol | Electric is cleanest and most convenient; gas gives the most heat and coverage but needs cylinder refills; bioethanol is stylish and low-maintenance but the lowest actual heat output. |
| Style | Freestanding / Wall-mounted / Tabletop / Fire pit | Freestanding covers the most area; wall-mounted saves floor space; tabletop is portable but lower output; a fire pit trades some heating power for visual ambiance and a gathering point. |
| Heat output | 1.5–2kW / 3–4kW / 6kW+ (or BTU equivalent on gas) | Matched to space size on paper, but real-world performance drops meaningfully in an open, windy spot regardless of the rated output. |
| Weatherproofing | IP44 / IP65 rating | IP44 is the practical minimum for splash protection outdoors; IP65 handles more direct exposure, worth it for anything left outside uncovered. |
Radiant heat and open, windy spaces don't mix
This is the biggest real-world gap between the spec sheet and how a heater actually performs, and it applies whether you buy gas or electric. Radiant heaters warm you directly rather than heating the surrounding air, which means wind doesn't just cool you down, it actively carries the heat away before it reaches you. Reviewers across this category consistently describe strong performance in enclosed or semi-enclosed spaces and a noticeably weaker feel in open, exposed ones, even on units rated for a large patio. If your outdoor space is genuinely open to the wind, a windbreak does more for how warm you'll actually feel than upgrading to a higher-wattage heater. A pergola helps for exactly this reason, and one with something growing on it does double duty as a windbreak and a nicer-looking space; we've covered the most popular vines that grow well on pergolas if that's a direction worth considering alongside the heater itself.
Fire pits and pellet heaters: ambiance first, heat second
A gas fire pit table or a wood pellet patio heater solves a different problem than a pure radiant heater: it's a visual centerpiece and a gathering point as much as a heat source, and the review data backs that framing, strong praise for appearance and atmosphere, heat output treated as a secondary benefit rather than the main selling point. If genuine warmth on a cold night is the priority, a dedicated propane or electric heater with a higher rated output is the more direct choice. If you want people to gather around something and warmth is a nice-to-have, a fire pit table earns its higher price for the experience it creates, not just the heat it puts out.
What we'd actually pick
Best budget tabletop
A 1500W electric tabletop unit at a genuinely low price, the easiest way to add a little warmth to a small table or balcony without committing to a full-size heater.
Best freestanding propane
50,000 BTU with wheels for easy repositioning, easy ignition, and a safety shut-off, well-reviewed as a strong all-rounder for a full-size patio.
Best wall-mounted electric
Waterproof, remote-controlled, with 8 heat levels, saving floor space entirely while still delivering real warmth to a covered or semi-covered patio.
Best gas fire pit table
A 28-inch propane fire pit table with a lid and lava rocks included, well-reviewed on both appearance and heat, at a fair price relative to the category's premium fire pit tables.
Best for ambiance
A wood pellet heater with a visible glass-tube flame, built for the look and feel of a real fire without needing a propane tank.
Best premium splurge
A recognized commercial-grade brand's dual-element infrared fixture, the kind of heater restaurants and serious outdoor living spaces actually install, for anyone who wants the real thing rather than a budget imitation.
Mistakes worth avoiding
- Buying based on rated heat output alone without accounting for how open and windy your actual space is.
- Choosing bioethanol expecting gas-level warmth, when it's genuinely the lowest-output fuel type of the three.
- Skipping the IP rating check and ending up with a unit that isn't actually built for outdoor splash exposure.
- Buying a fire pit table expecting it to out-heat a dedicated propane or electric heater of similar price.
- Leaving a gas heater without confirmed tip-over or auto shut-off protection running unattended.
So, which one
Small balcony or a single table: a budget electric tabletop unit over a full-size heater you don't have room for. Full patio, no permanent fixture wanted: a wheeled propane freestanding heater. Covered patio, want the floor space back: a wall-mounted electric unit. Want a gathering point as much as warmth: a gas fire pit table, knowing heat is the secondary benefit. Want the fire without the propane tank: a wood pellet heater for the look and feel of real flame. Serious about outdoor living and the budget allows it: a commercial-grade infrared fixture over a budget imitation. And whatever you land on, if your space is genuinely open to wind, a windbreak will do more for how warm you feel than a higher wattage number will.
