A screened porch is the best room in the house for three seasons and the worst room in the house for the other one. The screens let the breeze in and hold almost no heat, which is why a plain indoor space heater feels useless out there. What actually works is an electric infrared heater: it sends warmth straight to your body and your chair instead of trying to warm all that moving air. There is one real mistake to avoid, and it is the one that sends most people back to the store.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The VAGKRI 42-inch tower takes the top spot because it punches out serious radiant heat, assembles in about ten minutes, and is built for damp outdoor air. Skip to the comparison table if you already know you want a tower, and read on if you want to understand how wattage and mounting decide whether an electric heater for screened porch keeps you warm.
Our Picks at a Glance
How To Choose The Best Electric Heater For Screened Porch
A screened porch is an open-air room, so the heater you pick has to fight moving air, dampness, and the fact that you want warmth on your skin within a minute of sitting down. Here is what actually decides whether you will be comfortable out there.
Radiant heat versus air-warming heat
An infrared heater (also called a radiant heater) sends heat out in a straight line to whatever it hits — your legs, your chair, your table. It does not try to heat the air, which is why it works on a porch where the air is constantly being replaced by the outside.
A convection heater warms the air and relies on it staying put. That is fine in a closed room and close to useless on a screened porch. When you see “radiant” in a spec sheet, that is the one you want for semi-open space.
Watts decide how many people stay warm
A 1500-watt heater is the standard ceiling for a normal household circuit, and it is what most porch heaters at this level use. A 900-watt heater draws less power but throws less heat, so you will notice the difference the moment the temperature drops.
The number that actually matters is how far the heat reaches. Look for a stated coverage figure or a heating radius, because a heater that only warms a narrow line right in front of it will have you shuffling your chair around all evening.
Water resistance and where it sits
Covered porches still get mist, damp mornings, and the occasional sideways rain. An IPX5 rating means the unit can shrug off sprayed water, while IP65 adds protection against dust and stronger water jets. Either works under a roof.
Mounting type matters just as much as the spec sheet. A floor tower can be moved anywhere, a wall mount keeps the floor clear, and a ceiling or hanging unit frees up space entirely — but ceiling mounts need sturdy hooks and a spot where you can actually reach the controls or the remote.

In‑Depth Reviews
1. VAGKRI 42″ 1500W Electric Outdoor Infrared Heater with Remote
Our pick — 4.5★ from 100+ verified ratings; the strongest balance of quality and price.
The porch workhorse — a slim 42-inch tower that throws real heat from the second you flip it on.
If you want one heater that will handle a screened porch without fuss, start here. The VAGKRI runs on 1500 watts, which is the practical ceiling for a standard household circuit, and it starts warming you in 1 second using infrared radiant heat. Radiant means it heats objects and people directly rather than the air around them — exactly the trick you need when the screens keep swapping your warm air for cold.
What wins people over is the raw heat output, and it is the thing this unit is known for. Buyers report taking a 10×10 den from cold to comfortable in about five minutes, and several call it a powerhouse. At 42 inches it stands taller than most competitors, so the element radiates down over seated legs and laps instead of just your shins. One buyer reports it “heats up my entire patio within 10 minutes.”
Nine heat levels let you drop down to 620W once the porch settles into a comfortable temperature, which keeps the unit from cycling on and off at full blast. The 24-hour timer means you can set it before bed and let it run while the evening cools. It is also ETL Listed and built from weatherproof aluminum, so damp porch mornings do not bother it.
Why It Earns The Top Spot
- 1500 watts of infrared heat reaches you in 1 second, so no waiting in the cold
- Nine settings from 620W to 1500W let you dial in exactly the warmth you want
- 42-inch tower height radiates down over seated legs and laps
- 24-hour timer and ETL Listing make it easy to run unattended and safe to leave on
What To Know Before Buying
- Radiant heat is directional — a wide 100° range still means you want the tower facing your seating area
- At 5.7″D x 3.5″W x 41.7″H it needs a clear corner spot rather than being tucked behind furniture
Best for: almost any screened porch where you want one heater to do the job without fuss.
Worth knowing: infrared warms what it points at, so if your porch is long and narrow, point it down the length rather than across.
2. SereneLife Outdoor Electric Patio Heater 900W
The easy entry point — sun-like warmth, no gas bottles, and a footprint that slips into a corner.
The SereneLife is the smallest and lightest heater in this lineup at 7.7 pounds, and if you only need one seat warm on a small porch, it does that job with almost no setup.
What people appreciate most is the instant, sun-like, odorless warmth it delivers, plus the fact that it works while sitting on the ground without needing a wall mount. It has a 360-degree tip-over switch, overheat protection, and a mesh guard that keeps fingers and pet noses away from the heating element — genuinely useful if your porch has kids or dogs. The aluminum alloy frame carries an IP65 rating against dust and water, which is more than most covered porches will ever throw at it.
Two heat levels and a remote keep the controls simple. The 37.4-inch tower is only 9 inches square at the base, so it tucks into corners a bigger unit cannot reach. Owners mention that they wish it were a touch stronger on the coldest nights — that is fair, since it puts out 900 watts against the 1500 watts most porch towers run, so it is best suited to smaller spaces and moderate chill rather than deep cold.
Where it wins: best value in the lineup for genuinely small porches where 15 sq. ft. of coverage is all you need, and the IP65 rating is a real plus for damp outdoor air.
The trade-off to plan around: 900 watts is the cheapest ticket here, and that power gap is what owners feel when the temperature drops. It is not a flaw — it is a fit question. If your porch is bigger than a small sitting nook, step up to a 1500W unit.
Reach for this if: you have a compact porch, a tight corner, and modest cold to fight.
Look elsewhere if: you want to heat a wide area on the coldest nights — under 1000 watts will leave you wanting more.
3. Sundate 1500W Infrared Patio Heater with WiFi App Control
The porch heater that disappears — mount it up and out of the way, then control it from your phone.
If floor space is tight on your screened porch, the Sundate solves that problem completely. It is designed to go on a wall, under a ceiling, or hanging from a hook, so the entire footprint of a freestanding tower is gone. At 2.95 kg and 27.55″D x 5.51″W x 3.93″H, it is dramatically smaller and lighter than a 42-inch tower like the VAGKRI, and it mounts in seconds with the included hardware.
The heating is the same 1500 watts as the top pick, but the format changes the experience. It radiates directly to people and objects rather than warming the air, and because it hangs near the ceiling it points down over seated guests. The 104°F maximum temperature setting is adjustable across 9 heat levels, and both a physical remote and a WiFi app give you control — plus a second remote is included, which is handy if one goes missing.
The mounting flexibility is what buyers keep coming back to, since it works both horizontal and vertical with no auto-shutoff when flipped. There is a detachable design so you can store it off-season, and it comes with a cover for that purpose. One caveat worth planning for: the WiFi indicator light blinks when it is not connected, and customers note the remotes ship without batteries.
Best for: compact covered porches, balconies, and pergolas where you want maximum heat with zero floor use.
Honest note: it is built for small spaces. Several reviewers point out that 1500 watts on 120V spreads thin across larger patios, so if you have a wide porch you may end up wanting more than one unit or a central floor tower instead.
Go with this if: you want the heater off the floor and controllable from a phone or a second remote.
skip it if: you need to heat a large open area from one central point — this format is best for tight spaces.
4. Paraheeter Outdoor Electric Infrared Patio Heater 1500W
Three heaters in one — wall mount it, ceiling mount it, or drop it on the included tripod stand.
The Paraheeter is the heaviest unit here at 18.8 pounds, and that weight is exactly why it stays planted on a windy porch. It puts out 1500 watts of carbon infrared, throws heat in a 10-to-15 foot radius, and can be mounted three ways — wall, ceiling, or the adjustable tripod stand in the box. That flexibility is its whole pitch.
Its carbon fiber tube is rated for 10000 hours, and the IP65 housing resists dust and water spray on a covered porch. It ships with a safety metal grille and a 3-prong grounded plug, and it shuts off automatically if it is tipped over. Because it uses infrared rather than convection, there is no fan noise and no odor while it runs.
Shoppers say that it heats up quickly and provides solid heat, with the tripod making it easy to aim at your seating. The catch is the control setup — it only has HI and LOW, no middle setting and no timer, and the remote is a known weak point. It also warns loudly to remove the protective foam from the heating tube before you turn it on for the first time, and skipping that step is genuinely dangerous, so read that card in the box.
The strong points: the tripod stand makes it usable nearly anywhere, the 10000-hour carbon element is built to last, and the IP65 housing stands up to porch weather.
The honest limitation: no timer and only HI/LOW output means you lose the fine control that competing 9-level units give you. If you want to dial in a precise temperature and walk away, this is not that heater.
Best matched to: porches and decks where you want a heavy, stable, freestanding heater and do not need timer control.
Think twice if: you want precise heat levels and a set-and-forget timer built in.
5. Haimmy 42in Infrared Heater with Remote and Safety Lock
The one that survives a whole winter on a screened porch — and the one owners buy a second of.
This is the heater people keep buying twice, and that is the highest compliment a screened porch heater can get. It is a 42-inch tower running 1500 watts of carbon fiber infrared heat, and the heating tube spans roughly two-thirds of its height, which means it warms your feet and your body in one pass. Nine heat levels from 620W to 1500W and a 1-to-9 hour timer give you control without fiddling.
The safety package is why it holds up so well as a leave-it-running porch unit. There is a tip-over sensor that shuts the heater off if a pet knocks it, overheat protection, and a safety lock with memory that keeps children and pets from changing the settings by accident. It runs silently because it uses no fan, which makes it a good fit for a porch you sit and read on.
Owners run these hard: one reviewer keeps a pair running on a screened porch through freezing months and reports no trouble into year three. Another owner warms a 12×10 enclosed patio from 20°F to comfortable on level 9 in minutes. The IPX5 rating protects it against weather when it is out in the open, and the 42-inch height puts the radiant element high enough to cover your whole body from a seated position.
Standout Wins
- Safety lock with memory plus tip-over and overheat shutoff make it a real leave-it-on porch heater
- 9 heat levels and a 1-9 hour timer give you fine control
- Fan-free design means zero noise, ideal for a reading porch
- 42-inch height with a heating tube covering two-thirds of the column warms feet and body together
Where It Falls Behind
- Like every radiant tower here, the heat is directional — one heater warms the seats it points at, not the whole porch
- The listing claims 500 sq. ft. of coverage, which is optimistic for an open outdoor space; treat it as a small-to-medium porch heater
The pick for: anyone who wants to leave the heater running on a screened porch every evening without worry.
The limit to know: radiant heat goes where it points, so a pair of these set at opposite ends spreads coverage far better than one aimed at the middle.
6. VAGKRI Outdoor Heater, 1s Heating Carbon Infrared with Remote
The slim one you can carry from the screened porch to the garage without breaking stride.
At 8.4 pounds this VAGKRI is light enough to move one-handed, and it is built to be moved — the frame is only 3.58″D x 5.75″W, so it slips past patio furniture and tucks into corners other towers cannot. It runs 1500 watts of infrared heat and starts warming in 1 second, with the same 100° wide-angle throw you find on the brand’s flagship 42-inch tower.
Nine heat settings from 620W to 1500W and a 24-hour timer cover most evenings, and the whole body is weatherproof aluminum that produces no odors, chemicals, or fumes. That combination makes it easy to move between a screened porch in the fall and a garage workshop in the winter, which is exactly what a lot of buyers end up doing with it.
Where this one stands apart is the cord length. The 7-foot cable reaches past most porch chairs to an outlet without hunting for an extension cord, which matters because the manufacturer warns against running it on one. Buyers report it as a solid, quiet heater that takes the chill off, with a tall, slim profile that fits into tight spaces.
The case for it: flexible placement, a 7-foot cord, and a slim body that no other tower here matches for fitting into a narrow gap.
The caveat: it is a radiant heater, not an air-warmer, so on a truly wide porch it works best aimed right at your seat. If you want to heat all the air in a big space, a radiant unit is the wrong tool.
Suits: buyers who want one slim heater that moves between a porch, a garage, and a workshop with ease.
Not the one if: you plan to fit it with an extension cord — this unit shuts off if you do, so you need a reachable outlet.
7. Encyclpo Patio Heater for Outdoor Use, 1500W, 36 in Portable Tower
The ground-unit answer for anyone who hates the dry blast of a fan heater.
The Encyclpo is a 36-inch tower running 1500 watts through two high-efficiency carbon fiber heating wires, so it warms objects and people directly instead of blowing hot air around. There is no fan and no wind, which means it does all of its work in complete silence — a real benefit if you use your porch for quiet mornings rather than parties.
Three heat settings cover 600W, 900W, and 1500W, so you get a low, medium, and high rather than nine fine steps. It weighs 7.5 pounds, making it the lightest tower in this lineup, and it is rated IPX5 for water resistance so damp porch air is not a problem. The housing is made of flame-retardant material with tip-over and overheat shutoff built in.
What buyers appreciate is that it warms small spaces quickly — several use it in a garage or on a covered lanai, and the top-mounted controls mean no remote hunting is required. Owners also note it moves easily from room to room. One thing to plan around is that the power cord is shorter than some owners would like, and the unit is not meant to be run on an extension cord.
Where it shines: silent operation, lightweight portability, and a no-remote control layout that keeps things simple.
What to remember: only three heat settings means less fine-tuning than the nine-level units on this list, so if you like dialing in precise warmth, the extra steps matter.
A match for: noise-sensitive porches and anyone who wants to grab a heater by the handle and carry it.
Look past it if: you need many heat levels or a long reach from the outlet.
8. ThermoMate 1500W 38.5″ Portable Tower Infrared Heater with Remote
Sun-style heat without the dry blast — for anyone whose skin complains about regular heating.
The ThermoMate runs 1500 watts of infrared radiant heat and reaches warmth in 3 seconds, and its whole pitch is comfort rather than raw output. Because infrared heats objects instead of air, it does not dry out the room the way convection heating can, which is the reason a lot of buyers choose it for an enclosed porch or a living space attached to one.
Two heat levels — 750W and 1500W — cover a stated area up to 100 sq. ft., and the carbon fiber heating element is designed for less glare than standard tubes while producing steady heat over long stretches. It runs at 3.2 feet of remote range, keeps a 24-hour timer for scheduled evening warmth, and the aluminum housing carries an IP55 rating for dust and water resistance. Tip-over shutoff and overheat protection round out the safety side.
Where it really distinguishes itself is with people who usually find heaters uncomfortable. Owners who react badly to the dry, windy air that central systems push around report that this one is easy to sit next to because there is no draft — no noise, no blowing air. The swivel action helps it cover a bit more seating area without moving the whole unit.
Its specialty: gentle, draft-free warmth that people with dry-air sensitivity tend to prefer, with a timer that makes evening use straightforward.
The trade-off: output is mixed depending on the user — some sit close and find it perfect, others on a wide porch find it too thin. It is a heater that rewards careful placement.
Reach for it if: you want radiant warmth without the dryness that fan heaters produce.
Pass on it if: you need to push heat across a big open porch rather than warm the seat you are in.
Understanding the Specs
Watts And Coverage
Wattage is the measure of how much electrical power a heater uses, and it directly controls how much heat comes out. A 1500-watt heater is the highest most household circuits will carry safely, and it is what the strongest picks on this list use. A 900-watt unit draws less and heats less, which is fine for a small porch and thin for a big one. Pair wattage with a stated coverage figure — the physical area the manufacturer says it can warm — because two 1500-watt heaters can have very different reach depending on how the heat is aimed.
Infrared Versus Convection
Infrared heaters send heat out in a straight line to whatever they are pointed at, warming people and objects directly instead of the air. Convection heaters warm the air and let it circulate on its own. On a screened porch, where outside air keeps replacing the warm air, infrared has the clear advantage because it does not depend on that air staying put. The catch is direction: you have to aim an infrared heater at your seating rather than expecting it to fill the room evenly.

Final Thoughts: The Verdict
For most screened porches, the electric heater for screened porch winner is the VAGKRI 42″ 1500W Tower because it pairs 1500 watts of instant infrared heat with nine levels, a 24-hour timer, and a slim frame that fits a porch corner without being in the way. If your priority is leaving the heater running every evening without a second thought, the Haimmy 42in adds a safety lock and a memory function on top of the same 1500 watts, and it has owners running it for years on end. For tight spaces where floor room is scarce, the Sundate WiFi model mounts to the wall or ceiling and keeps the ground clear.
