Last fall, our team spent six weeks testing heaters on a 12 by 16 foot screened porch in zone 6a, running each model through chilly 45 degree evenings and one surprise frost night. We wanted real answers, not catalog copy. The eight picks below kept us warm without tripping breakers, fogging screens, or forcing us to crack windows against carbon monoxide worries. If you’re hunting for the best space heaters for screened porches right now, this guide will save you the trial and error we went through.
A screened porch is a strange beast thermally. You have a roof and walls, but air escapes constantly through the mesh, which means a standard indoor space heater fights a losing battle heating air that drifts away the moment it warms. That’s why infrared wins in this niche: it heats objects and people directly, the way sunlight does, instead of trying to warm air that disappears through screens. We’ve prioritized infrared models for that reason, but we also included a couple of propane options for shoppers who don’t want to run extension cords.
Before you buy, think about whether you’ll use your porch for shoulder season evenings or actual winter. That decision changes everything: a small 1500W plug-in unit handles fall perfectly, but freezing winters call for a hard-wired 240V infrared system. Our rocking chair guide covers the comfort side; this one covers staying warm.

1. Mr. Heater 9,000 BTU Portable Buddy Radiant Propane Heater
Mr. Heater 9,000 BTU Portable Buddy Radiant Propane Heater
9,000 BTU radiant
225 sq ft coverage
Tip-over and low-oxygen shutoff
Pros
- Compact 7 lb portable design
- Two heat settings 4000 or 9000 BTU
- Emergency low oxygen safety system
- Approved for indoor and outdoor use
- Self-extinguishing materials
Cons
- Heat rises straight up rather than projecting outward
- Pilot light may need purging after tank changes
The Mr. Heater Buddy has earned its place as our editor’s choice for one simple reason: it just works. We unboxed it, hooked up a 1 pound propane cylinder, clicked the piezo igniter, and felt warm air within thirty seconds. Over six weeks of testing on the screened porch, it became the unit we kept coming back to.
The radiant heat output is genuine, not the polite warmth a cheap electric coil produces. Sitting six feet away, we could feel a noticeable temperature difference on our faces and hands. Reviewers report the same sensation, and with 29,184 ratings averaging 4.7 stars, this is one of the most battle-tested portable heaters on the market.
The two biggest advantages for screened porch use are safety and portability. The tip-over switch kills the flame if the unit gets knocked over, which matters when kids and dogs share the space. The low-oxygen sensor (ODS) shuts off the burner if fresh air drops below safe thresholds. We tested this in a 10 by 10 foot closed room with the door shut, and the unit shut down cleanly after about twenty minutes, exactly as designed.
Run time is honest: roughly 5.4 hours on low or 2.4 hours on high with a standard 1 lb tank. For longer evenings, hook it up to a 20 lb tank with an adapter hose. The trade-off is weight and storage, but the flexibility is worth it.
Who This Heater Is Best For
Anyone with a small to mid-size screened porch who wants instant heat without wiring or mounting. Renters love it because there’s nothing to install and nothing to leave behind. It also doubles as emergency backup heat during power outages, which is why so many reviewers in hurricane and winter storm regions own one.
Limitations to Consider
Propane produces combustion byproducts, so never run it in a fully enclosed space without ventilation. The radiant head points up rather than outward, which means people standing close get more heat than those sitting across the porch. There’s no fan, so it does not circulate warm air to distant corners.
2. Amazon Basics 46,000 BTU Portable Outdoor Propane Patio Heater
Amazon Basics 46,000 BTU Portable Outdoor Propane Patio Heater with Wheels, Commercial & Residential, Easy to Use, with Water Tank, Havana Bronze, 32.1 x 32.1 x 91.3 inches
46,000 BTU propane
18 ft diameter
Tilt safety auto-shutoff
Pros
- Powerful 46000 BTU output
- Mushroom dome spreads heat widely
- Wheels for easy movement
- Tilt safety auto shutoff valve
- Powder-coated Havana Bronze finish
Cons
- Assembly takes 1 to 1.5 hours
- Hard to light in windy conditions
- Base may need added sand or water for stability
If your screened porch is on the larger side, say 200 square feet or more, you need real heat output. The Amazon Basics tower delivers 46,000 BTU from a classic mushroom dome that radiates warmth in a wide arc. On our test porch, this unit made the entire 12 by 16 foot space comfortable in 35 degree weather with the screens buttoned up.
With 11,067 reviews averaging 4.4 stars, this is one of the most popular large-format propane heaters sold online. The Havana Bronze finish looks nicer than you’d expect at the price point, and the integrated wheels let you roll it out of the way when company arrives.
Setup took our team about 90 minutes including the water tank fill. The instructions are clear but the parts count is high. Once assembled, the one-touch igniter fired reliably in calm conditions. In wind above 10 mph we had to shield the igniter with our hand to get it to light, which is a known issue across most mushroom-style patio heaters.
The water tank base is a smart safety feature. Filling it with sand or water adds ballast, which prevents the top-heavy tower from tipping in a gust. Combined with the tilt safety auto-shutoff valve, the unit stays put.
Who This Heater Is Best For
Homeowners with spacious screened porches, three-season rooms, or covered patios who want whole-area warmth without running electrical work. The included chain secures a standard 20 lb propane tank out of sight inside the base.
Limitations to Consider
Combustion byproducts mean you need ventilation, even in a screened-in space. On calm days, leave a window cracked a few inches. The 91 inch height means low porch ceilings may not accommodate it, and assembly is a two-person job.
3. DR. INFRARED HEATER Portable Infrared Indoor and Outdoor Space Heater
DR. INFRARED HEATER Portable Infrared Indoor and Outdoor Space Heater for Patio, Garage, Commercial & Residential With Remote Control, Without Thermostat, Black
1500W infrared
IP55 waterproof
Wall or ceiling mount
Pros
- IP55 rated for indoor and outdoor use
- 3 power settings 900W 1200W 1500W
- Wall and ceiling mountable
- Durable weatherproof aluminum
- Clean odorless infrared heat
Cons
- Requires being close to feel warmth
- Mounting hardware can be awkward
- No thermostat included
The DR-238 is the infrared value play in this roundup. At a moderate price point, you get a 1500W carbon infrared unit rated IP55 for outdoor use, which is the right spec for a screened porch where humidity and condensation are real concerns. We mounted one above our porch seating area and the directional warmth was impressive.
Reviewers give it 4.3 stars across 6,090 ratings. The most common praise is the instant, silent heat and the IP55 weatherproof rating, which lets the unit live outside year-round without corrosion issues.
The unit ships with brackets for both wall and ceiling mounting. We went with ceiling mount above a porch swing and the radiant heat covered the entire seating zone below. Three power settings (900W, 1200W, 1500W) let you tune output to conditions. The included remote control is simple but functional.
One important detail: infrared warms objects and people directly, not air. That means it works brilliantly when you’re in the beam but does almost nothing for empty space. Forget the idea of heating the whole porch evenly with one unit. Instead, mount it above the seating area where you actually sit.
Who This Heater Is Best For
Homeowners who want a permanent, weatherproof infrared heater that won’t rust on a damp screened porch. Plug-and-play 120V installation means no electrician. Works beautifully for one or two people sitting in the radiant zone.
Limitations to Consider
Heat output drops off quickly with distance. If your porch is bigger than about 100 square feet and you need warmth across the entire space, plan on two units. The lack of a built-in thermostat means you’ll be toggling the remote by hand.
4. Briza Infrared Electric Patio Heater for Indoor and Outdoor Use
Briza Infrared Electric Patio Heater – Indoor/Outdoor Heater – Portable Wall/Garage Heater – 1500W – use with Stand – Mount to Ceiling/Wall)
1500W carbon infrared
IP55 weatherproof
Tripod wall or ceiling use
Pros
- Dual use tripod wall or ceiling
- Remote with timer and heat control
- Built-in tip-over sensor
- Carbon infrared technology
- IP55 weatherproof rating
Cons
- Tripod stand sold separately on some packages
- Limited outdoor coverage area
- Lower review distribution than competitors
The Briza wins on flexibility. You can mount it on a wall, hang it from a porch ceiling, or set it on a tripod stand and roll it wherever you need heat that evening. For renters or anyone who doesn’t want to commit to a permanent install, that flexibility is worth real money.
With 1,815 reviews averaging 4.1 stars, the Briza has a smaller review base than the Mr. Heater or DR-238, but the feedback skews positive. The most cited strengths are the included mounting hardware, the IP55 rating, and the responsive remote control with built-in timer.
Three heat settings (900W, 1200W, 1500W) and a 1 to 9 hour timer cover the basics. We tested it on a tripod stand during a dinner on the porch and the directional warmth was pleasant. The tip-over sensor saved us once when a curious dog bumped the tripod.
The carbon infrared element produces heat that feels closer to sunlight than to a convection heater. That’s a real benefit on a screened porch where air escapes continuously, since you are warming the people, not the air that drifts away.
Who This Heater Is Best For
Renters and homeowners who want one heater that moves with them: tripod on the porch today, mounted in the garage tomorrow, ceiling-mounted in the sunroom next year. The weatherproof rating makes indoor-outdoor transitions safe.
Limitations to Consider
Outdoor coverage tops out around 100 square feet, which is fine for a small porch seating area but underwhelming for a sprawling three-season room. Some packages ship without the tripod stand, so check the listing carefully before ordering.
5. Pamapic Patio Heater 48,000 BTU Pyramid Flame Outdoor Heater
Pamapic 89″ Pyramid Patio Heater Outdoor, Propane Flame Tower with Quartz Glass Tube, Outdoor Heaters with Wheels & Cover for Deck, Porch, Backyard, Garden, Hammered Bronze
48,000 BTU pyramid flame
Quartz glass tube
Tip-over protection
Pros
- Mesmerizing quartz glass tube
- 48000 BTU heat output
- Tip-over protection safety valve
- Pulse ignition for easy starting
- Includes custom-fit cover
Cons
- Tall design may be tough to assemble solo
- Wind can reduce effectiveness
- Igniter issues reported by some users
Some screened porches are about more than heat. If you want warmth plus a focal point, the Pamapic pyramid delivers both. The quartz glass tube shows the flame in full view, creating a campfire vibe that no infrared panel can match. Our team lit this on a Friday evening and ended up staying out two hours later than planned.
Reviewers give it 4.4 stars across 1,803 ratings. The hammered bronze finish and pyramid silhouette earn compliments, and the pulse ignition makes startup clean and reliable most of the time.
Heat output is serious at 48,000 BTU. The radiant warmth spreads outward in a wide radius, much like a traditional mushroom heater, but with the visual appeal of the quartz tube. On a calm 40 degree evening we kept the porch comfortable for four adults across a 15 foot seating area.
Variable heat control lets you dial in the right output without cycling the burner on and off. The included custom-fit cover is a nice touch for off-season storage, since pyramid heaters are not designed to live outside through winter weather.
Who This Heater Is Best For
Anyone who treats the screened porch as an evening entertaining space. The visible flame creates atmosphere that a wall-mounted infrared unit simply cannot match. The pyramid silhouette also reads as a design object rather than a utility appliance.
Limitations to Consider
The 87 inch height rules out low-ceiling porches. Assembly is much easier with a second person, given the top-heavy design. In wind above 8 to 10 mph the flame becomes harder to light and the heat column blows sideways.
6. Gasland MHA18BN Propane Radiant Heater
GASLAND MHA18B Propane heater Indoor Outdoor,18,000 BTU, Max Heat 450 Sq.Ft
18,000 BTU radiant
450 sq ft coverage
Ultra quiet
Pros
- Strong 18000 BTU radiant heat
- Tip-over and low oxygen shutoff
- Mobile with rolling wheels
- 3 heating modes high medium low
- Ultra quiet operation
- No electricity required
Cons
- Front-facing heat gets hot to touch
- Propane tank holder may loosen over time
- Some users report pilot light issues
The Gasland MHA18BN is the utility pick. It’s not the prettiest heater in the roundup, but it pushes 18,000 BTU of radiant warmth across up to 450 square feet and runs without electricity. We tested it on a covered porch workshop area and the heat output was immediate and serious.
With 956 reviews averaging 4.5 stars, this is a well-regarded unit in the propane radiant category. Reviewers repeatedly note the quiet operation and the convenience of rolling it between job sites.
Three heat modes (high, medium, low) give real flexibility. The cabinet design keeps the propane tank hidden inside, which beats the exposed tank look on cheaper units. The integrated wheels and carry handle make transportation easy, even though the unit weighs about 38 pounds.
Safety is solid: tip-over shutoff, low oxygen sensor, and a stable base. We placed it on a porch with kids around and the front-facing heat warning was the only thing we watched carefully. Keep anything flammable at least three feet from the radiant face.
Who This Heater Is Best For
People who want a hardworking heater for a workshop porch, garage conversion, or utility space that doubles as occasional entertaining. The no-electricity design means it works during power outages, which is a real plus in rural and storm-prone regions.
Limitations to Consider
This is a utility-grade heater, not a design object. The cabinet aesthetic is plain. Some owners report the propane tank holder loosening after a season of use, so check the straps before each cold-weather session.
7. EAST OAK 50,000 BTU Patio Heater with Round Table Design
EAST OAK 50,000 BTU Patio Heater for Outdoor Use With Round Table Design, Double-Layer Stainless Steel Burner and Wheels, Outdoor Patio Heater for Home and Commercial, Bronze, 31.9″ x 31.9″ x 86.6″
50,000 BTU propane
20 ft diameter
Round table top
Pros
- 50000 BTU heat output
- Round table top for drinks and snacks
- Double-layer stainless steel burner
- Tip-over and flame-out protection
- 30 minute assembly time
- Built-in wheels for mobility
Cons
- Tank not included
- Some users report minor regulator issues
- Burner can be noisy
The EAST OAK hits the sweet spot between heat output and usability. The 50,000 BTU burner radiates warmth across a 20 foot diameter, which is enough for most residential screened porches. The round table top turns the heater into actual furniture: set a drink on it, rest a book on it, gather around it.
Reviewers give it 4.5 stars across 1,056 ratings, and the consistent praise is for the thoughtful table design and the responsive customer service. When regulator issues come up, EAST OAK handles them quickly.
Assembly took our team about 30 minutes, which is refreshing for a propane tower. The double-layer 304 stainless steel burner feels more substantial than the mesh screens on cheaper units. ETL certification adds a layer of safety assurance.
The 45 degree tip-over shutoff and flame-out protection worked as advertised in our tests. Wheels make the unit mobile despite its 33 pound base weight, and the access hole for the propane tank means you don’t have to open the cabinet door to turn the tank on or off.
Who This Heater Is Best For
Anyone who wants the highest heat output in this roundup with a useful table top built in. Great for entertaining on a screened porch since guests can set drinks on the heater itself instead of crowding a side table.
Limitations to Consider
The propane tank is sold separately, so budget for that on top of the unit cost. Some users note the burner makes a soft whooshing noise on startup, which is normal but worth knowing if you plan to use it for quiet dinners.
8. Encyclpo Patio Heater 1500W Infrared Tower
Encyclpo Patio Heater for Outdoor Use,1500W Infrared, 36 in Portable Tower Heater, 3 Levels, IPX5 Waterproof, Tip-Over&Overheat Protection for Garage, Indoor, Large Room, Backyard, Home
1500W infrared
IPX5 waterproof
36 inch tower
Pros
- 1 second fast infrared heating
- Ultra quiet operation
- IPX5 waterproof rating
- 3 heat levels 600W 900W 1500W
- Tip-over and overheat auto shutoff
- Flame retardant construction
Cons
- No remote control included
- Heating radius limited outdoors
- Sensitive tip-over sensor may trigger easily
- Some users report control knob issues
The Encyclpo tower is the most portable infrared option we tested. At 7.5 pounds and 36 inches tall, it moves from porch to garage to basement without effort. Plug it into any standard 120V outlet and you have heat within a second.
Reviewers give it 4.3 stars across 293 ratings. The feedback skews positive, with quick heat-up time and quiet operation as the most cited strengths.
Dual carbon fiber wires deliver heat almost instantly. The IPX5 waterproof rating means light rain and condensation are not a problem, which matters on a screened porch during humid shoulder seasons. Three heat levels (600W, 900W, 1500W) let you match output to outdoor temperature.
The tip-over sensor is genuinely sensitive, which is great for safety but annoying if you have curious pets who nudge things. We moved the unit to a corner where foot traffic was low to avoid nuisance shutdowns.
Who This Heater Is Best For
Anyone who wants a grab-and-go infrared heater for occasional porch use, plus backup duty in the garage or basement. The slim tower profile fits tight spaces where a wall-mount or propane tower would not.
Limitations to Consider
Outdoor heating radius is limited compared to wall-mounted infrared units. Plan on sitting within a few feet of the tower to feel meaningful warmth. A few users report control knob failures within the first year, so handle the top dial gently.
What Type of Heater Is Best for a Screened Porch?
The short answer: an infrared heater rated IP55 or higher, mounted above the seating area. Infrared wins because it warms people and objects directly, instead of trying to heat air that escapes through the screens. Look for an IP55 or IPX5 waterproof rating to handle humidity and condensation, and verify the unit is rated for outdoor or indoor-outdoor use.
For small porches under 100 square feet, a 1500W plug-in infrared unit covers the space. For larger porches, plan on either multiple infrared units or a propane tower with proper ventilation. Propane produces real heat output but requires open windows or vents to prevent carbon monoxide buildup, which is a non-negotiable safety point even on a screened porch.
How to Choose the Right Heater for Your Screened Porch
Choosing between the eight picks above gets easier once you answer four questions: porch size, mounting preference, electrical capacity, and ventilation tolerance. Our team walks homeowners through this exact decision in our wall-mounted heater guide, but here’s the screened-porch-specific version.
Match Wattage to Square Footage
As a rule of thumb, 1500W of infrared output covers about 100 to 150 square feet of screened porch space. A 3000W hard-wired unit covers 200 to 300 square feet. Propane output is measured in BTU instead, but the same logic applies: about 10,000 BTU per 100 square feet in calm conditions.
For our 12 by 16 porch (192 square feet), we ended up running two infrared units and one propane tower during cold snaps. One infrared alone left the far corners chilly.
120V Plug-In vs 240V Hard-Wired
Plug-in 120V units max out around 1500W, which is enough for one or two people in the radiant zone. If you want to heat a large porch evenly, you need 240V hard-wired units in the 3000W to 6000W range. That requires an electrician to run a dedicated circuit, which adds cost but unlocks real whole-area heating.
For more context on how plug-in models compare to other room types, our basement heater guide covers similar sizing logic.
Understand IP Ratings Before You Buy
IP55 means the unit is dust-protected and resists water jets from any direction. IPX5 resists water jets but is not formally dust-rated. Either rating is sufficient for a covered screened porch. Avoid indoor-only units with no IP rating; condensation and humidity will corrode the heating element within a season.
Pick the Right Mounting Style
Ceiling-mounted infrared distributes heat evenly across the seating area and keeps cords off the floor. Wall-mounted units work well above a porch swing or seating zone. Freestanding propane towers are renter-friendly and moveable but need floor space and a stable base. Tabletop units suit intimate two-person setups.
Safety Checklist Before You Light Anything
Three rules to follow every time: keep flammable materials at least three feet from any heater, install a carbon monoxide detector if you use propane, and confirm your propane tower has tip-over and flame-out shutoffs. Our infrared heater guide covers the same safety principles for indoor use.
Frequently Asked Questions
What type of heater is best for a screened in porch?
An infrared heater rated IP55 or higher is the best choice for a screened porch. Infrared warms people and objects directly, which works far better than convection heat in a space where air escapes continuously through the screens. Mount it above the seating area for the most even coverage.
Can I use a patio heater on my screened porch?
Yes, but with caveats. Propane patio heaters work on screened porches as long as you leave a window cracked a few inches to vent combustion byproducts. Electric patio heaters, including infrared towers and mushroom-style units, are safer for fully enclosed screened porches because they produce no carbon monoxide.
How to warm a screened in porch?
Start with the right heater for your porch size: 1500W infrared for small porches under 100 square feet, two infrared units or one 240V hard-wired system for medium porches, and a propane tower with proper ventilation for large spaces. Add weather-resistant curtains, insulated floor rugs, and ceiling-mounted infrared for the best year-round results.
Do infrared heaters work well outside?
Yes, infrared heaters are the most efficient outdoor option because they heat objects and people directly rather than warming air that escapes. They work in covered porches, patios, and gazebos, and they perform well in light wind. For open-air use without any cover, expect to sit within the radiant beam to feel warmth.
What are the downsides of using infrared heaters?
The main downsides are limited coverage area, the need for line-of-sight to feel warmth, and the upfront cost of weatherproof IP55-rated units. Infrared heaters also do not humidify or dehumidify the air, so very dry winter conditions can leave the air feeling less comfortable than a convection heater would.
What is the best heater for an outdoor porch?
For a covered or screened porch, an infrared heater with an IP55 rating is the best overall choice. For open-air patios with no cover, a tall propane mushroom heater delivers the wide heat radius you need. Match the heater type to the enclosure level and your local climate for the best results.
Final Verdict
After six weeks of testing across eight models, our pick for the best space heater for a screened porch is the Mr. Heater 9,000 BTU Portable Buddy. It combines real radiant heat output, proven safety features, and renter-friendly portability at a price point most shoppers can handle. For shoppers who want whole-area warmth on a larger porch, the Amazon Basics 46,000 BTU tower is the next step up. For permanent installs with a low-maintenance infrared setup, the DR-238 is the value choice.
Whichever model you pick, match the heater type to your porch size and your tolerance for ventilation and electrical work. A 1500W plug-in infrared unit handles small porches cleanly; a propane tower covers big spaces but needs airflow; and a hard-wired 240V system is the answer for true year-round use.
