Best Infrared Patio Heater for a Deck (2026): 5 Compared

Compare the picks

Specifications are manufacturer rated, collected 22 October 2026. Only one of these listings states a warranty term; two state a safety lab listing.

How we scored them

Each heater is scored on performance, build, value, safety and warranty, using only what the listing publishes. For an electric patio heater, safety means a stated lab listing or stated safety features like overheat protection and tip-over shutoff; the DR-239, SereneLife, thermomate and BrewVox state one or more, the AEROZY states none. One listing states a warranty term: the DR-239 at one year.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

How to choose the best infrared patio heater for a deck

Power: 3000W on 220V vs 1500W on 120V

This is the first decision, because it decides your wiring. The DR-239 runs 3000W on 220V to 240V at 12.5A with a UL NEMA 6-15P plug, so it needs a 240V circuit, not a standard deck outlet. The other four are 1500W plug-in units that run on 120V. A 240V circuit is common for a shop or a wired deck, but if your deck has only standard outlets, the 1500W group is the whole shortlist. See our electric vs infrared patio heater guide for how the two power classes behave.

Mounting: wall, ceiling or pedestal

A deck heater should be out of the walkway. The DR-239 ships with wall and ceiling mounting brackets, the thermomate wall mounts, and the BrewVox mounts on a wall or ceiling and also works with an optional tripod stand. The SereneLife is a tower that stands on the deck, and the AEROZY is a pedestal floor unit. Wall and ceiling mounts keep the floor clear for furniture and foot traffic; towers and pedestals are easier to move but need floor space and a stable spot out of the wind.

Coverage: match the heater to the deck

Only two listings state a coverage figure. The thermomate covers up to 80 sq. ft., the SereneLife 18 sq. ft., and the other three state none. Treat each figure as the maker’s claim for calm conditions; wind and open sides shrink real coverage. For a small seating nook, the SereneLife’s 18 sq. ft. is honest. For a full deck, the thermomate’s 80 sq. ft. is the only stated figure that reaches, and the DR-239’s 10,260 BTU is the most raw heat here even without a stated coverage number. The thermomate listing even suggests 2 to 3 heaters for larger outdoor environments, which is the honest answer for a big deck: one 1500W unit cannot carry the whole space alone.

Controls: heat levels, timers and thermostats

Infrared heaters warm instantly, so controls are about comfort, not warm-up. The thermomate and AEROZY each offer 9 heat levels, the DR-239 has 2 speeds, and the SereneLife has 2 heat levels. Timers matter on a deck: the thermomate and BrewVox have 24-hour timers, the AEROZY a 9-hour timer. The BrewVox goes further with a thermostat that holds 41°F to 113°F and an app plus remote, so you can pre-heat the deck on the way home. The DR-239, thermomate and SereneLife include remotes; the AEROZY does too.

Safety listings and weather ratings

An electric heater on a wooden deck should carry a lab listing. The DR-239 is ETL listed with a UL NEMA 6-15P plug, the SereneLife is ETL-certified, and the thermomate cites a 3.2ft UL approved cable. The BrewVox states overheat sensors and an automatic tip-over shutoff, and the SereneLife adds a 360-degree tip-over switch, overheat protection and a mesh guard. For weather, the DR-239 is IP55 and the thermomate, SereneLife and BrewVox are IP65; the AEROZY states no rating. An IP rating keeps rain out, but no heater should sit in standing water or a driving storm.

Remotes, timers and who includes them

Every one of these five includes a remote, which matters on a deck: you adjust the heat without getting up. The DR-239 remote switches between its 2 power levels and standby mode. The thermomate and AEROZY remotes each run 9 heat levels, with the thermomate adding a 24-hour timer and the AEROZY a 9-hour timer. The SereneLife remote runs 2 heat levels with no timer stated. The BrewVox pairs its remote with a smartphone app, a 24-hour timer with memory and the 41°F to 113°F thermostat, so the heater can pre-heat the deck and hold a set temperature by cycling on and off. If you want the deck warm when you step out, the BrewVox is the only one here that does it by itself; the rest need you to press the button.

Frequently Asked Questions

Can I mount an infrared patio heater on a wooden deck?

Yes, with the right mount. The DR-239, thermomate and BrewVox all include wall mounting hardware, and the DR-239 and BrewVox also mount to a ceiling. Mount to solid structure, not just decking boards, and follow the clearances in the maker’s manual.

Do infrared patio heaters work in the wind?

Better than heaters that warm the air. Infrared warms people and surfaces directly on its radiant path, so a breeze steals less of it than it does from a convection heater. A sheltered corner of the deck still performs noticeably better than an exposed edge.

What power supply does a 3000W patio heater need?

The DR-239 runs on 220V to 240V at 12.5A with a NEMA 6-15P plug, so it needs a 240V circuit. The other four are 1500W units that plug into a standard 120V outlet. Check your panel before you buy the 3000W class.

Are infrared patio heaters safe to leave on overnight?

They should not run unattended. Use the timers: the thermomate and BrewVox have 24-hour timers and the AEROZY a 9-hour timer, and the DR-239, SereneLife and BrewVox state overheat protection with automatic shut-off. A timer plus a shutoff is the safe way to end the evening.

Can an infrared heater stay outside in the rain?

The IP65 models (thermomate, SereneLife, BrewVox) and the IP55 DR-239 are rated for outdoor exposure, so normal rain is within their rating. The AEROZY states no weather rating, so it should come under cover. Even rated units last longer mounted under an eave than in the open.
