Key Takeaways
- Whole-home and single-room systems serve different jobs: the DELLA and Comfort Temps mini splits, plus the Goodman furnaces, are larger installed systems; most other picks are meant for targeted heating.
- The DELLA Serena is the most versatile installed option in this lineup: its mini split design provides both heating and cooling, though it requires planning for installation and capacity.
- Portable infrared heaters prioritize placement flexibility: EdenPURE models and the Dr. Infrared DR-968 can serve a room without permanent installation, but they are not substitutes for a central system.
- Wall heaters trade mobility for a fixed footprint: Smart Envi, EnviMAX, HICFM, and DREO options can keep floor space clear, while electrical requirements and mounting location affect fit.
- Radiant flooring is a targeted comfort upgrade: the HEATIT mat covers only 35 square feet, so it is suited to a defined small area rather than whole-home heating.

More Details on Our Top Picks
JNDRO Wall-Mounted Space Heater with Thermostat and Remote Control
This option stands out for directional flexibility that most wall heaters simply don’t offer. The choice of 60°, 90°, or 120° oscillation means a buyer can sweep warm air across a long living room instead of heating a single fixed spot, which is where fixed-panel units like the Envi Wi-Fi heater fall short. The ECO thermostat mode adjusts output to the ambient temperature, so the 1500W element isn’t running flat-out all day, and the child lock makes it a sensible pick for households with curious toddlers. The tradeoff is coverage: 200 sq. ft. is modest next to the EdenPURE CopperPLUS’s 1,000 sq. ft. claim, so this is a targeted room-warmer rather than a whole-floor solution. You’ll also need to supply two AAA batteries for the remote before it works out of the box.
Pros:- Selectable 60°, 90°, or 120° oscillation spreads heat better than fixed wall panels
- ECO thermostat mode scales power to room temperature for efficiency
- Child lock plus 24-hour timer suit households with small kids
- Remote and LED display make adjustments easy from across the room
Cons:- 200 sq. ft. coverage is among the smallest in this lineup
- Remote requires separately purchased AAA batteries
Best for: Renters and families who want a wall-mounted heater that spreads heat across a medium bedroom or nursery without a bulky floor unit
Not ideal for: Anyone heating open-plan spaces over 200 sq. ft. — the coverage is too limited to matter in a large room
- Power:1500W
- Mounting:Wall mount
- Heating coverage:200 sq. ft.
- Temperature range:41°F–95°F
- Fan speeds:3
- Oscillation angles:60°, 90°, 120°
- Timer:24 hours
- Voltage:120V
Our verdict“Buy this if you want directed, oscillating warmth in a single bedroom or office and can live with its limited reach.”
EdenPURE CopperPLUS Portable Infrared Heater
Where the wall-mounted JNDRO is locked to one room, the CopperPLUS earns its place through room-to-room mobility. Rolling casters mean a buyer can wheel it from the living room to a bedroom on cold nights without lifting, and the washable filter eliminates the recurring filter costs that many tower and fan heaters quietly add. Compared with the EdenPURE GEN21, this model leans harder into raw heating: 24 temperature settings across 40°F to 90°F plus high and low power modes give finer control than most single-dial portables. The touch-safe front grill and tip-over shutoff make it safer around kids and pets than exposed-element heaters. The honest drawback is the cord — a 6-foot tether limits placement — and at 24 lbs, carrying it upstairs is a two-hand job.
Pros:- Rolling casters allow easy movement between rooms
- Washable filter removes ongoing replacement costs
- 24 temperature settings and two power modes offer fine-grained control
- Dual overheat sensors and tip-over shutoff add real safety
Cons:- 6-foot power cord limits where it can be placed
- 24 lbs is heavy to carry up stairs when casters aren’t an option
Best for: Homeowners who want one heater they can roll between rooms and dial in precisely rather than buying multiple units
Not ideal for: Anyone without a nearby outlet — the 6-foot cord and corded design restrict placement in rooms with few sockets
- Heating coverage:Up to 1,000 sq. ft.
- Heat output:5,000 BTU
- Power modes:1,500W high; 1,000W low
- Temperature settings:24 (40°F to 90°F)
- Heating method:Radiant infrared
- Weight:24 lbs
- Power cord:6 feet, 14-gauge
- Safety features:Dual overheat sensors, tip-over shutoff, touch-safe grill
Our verdict“This makes the most sense for buyers who want flexible, precise heat they can move wherever the cold spots are.”
DELLA Serena 18,000 BTU 22 SEER2 Smart Wi-Fi Mini Split Heat Pump
This is the only true HVAC-grade option in this batch, and it plays a different sport than the portable heaters around it. As a heat pump, the Serena delivers both heating and cooling for spaces up to 1,000 sq. ft., with inverter technology that modulates output instead of cycling on and off — the reason it hits a 22 SEER2 efficiency rating that plug-in 1500W units can’t approach. Voice control through Alexa and Google Home and a 22 dB mute mode put it ahead of simpler units like the EdenPURE GEN21, whose “cooling” is just a fan. The real tradeoffs are commitment and cost of entry: it requires professional installation, runs on 208–230V household circuits, and altering the included 16.4 ft. line set means a refrigerant adjustment. This is a purchase for someone solving climate control permanently, not supplementally.
Pros:- True heat pump delivers both heating and cooling, not just fan circulation
- 22 SEER2 inverter efficiency far outclasses plug-in resistance heaters
- Runs at 22 dB in mute mode — quieter than any portable here
- Wi-Fi, Alexa, and Google Home control plus a 16.4 ft. installation kit included
Cons:- Professional installation required, adding cost and scheduling hassle
- Changing the line-set length requires refrigerant adjustment by the installer
Best for: Homeowners ready to permanently solve heating and cooling for a large room or addition with one efficient ductless system
Not ideal for: Renters or anyone wanting plug-and-play heat — professional installation and a 208–230V circuit are non-negotiable
- Capacity:18,000 BTU/h (1.5 tons)
- Type:Ductless heat pump (heating and cooling)
- Efficiency:22 SEER2
- Coverage:Up to 1,000 sq. ft.
- Voltage:208–230V
- Refrigerant:R-32
- Noise level:22 dB in mute mode
- Connectivity:Wi-Fi; Alexa and Google Home
- Installation kit:16.4 ft. copper line set
Our verdict“Choose this if you’re outfitting a 1,000 sq. ft. space once, properly, rather than patching it with space heaters.”
EdenPURE GEN21 Infrared Heater with Bladeless Cooling Fan, 1500W
The GEN21’s pitch is year-round usefulness: a 1500W copper PTC infrared heater in winter paired with a bladeless fan for summer circulation. Compared with its sibling the EdenPURE CopperPLUS, it trades casters and 24 temperature settings for a smaller footprint, a digital touchscreen, and a memory function that remembers your last settings — a genuinely useful detail for daily use. The adjustable louvered vent lets a buyer aim heat where it’s needed, something flat panel heaters like the Envi can’t do at all. Be clear-eyed about the limits, though: the “cooling” side is air movement, not refrigeration, so it won’t lower room temperature the way the DELLA mini split does. And the 1,000 sq. ft. coverage claim is optimistic for 1500W — expect strong results in mid-sized rooms, not cavernous ones.
Pros:- Heater plus bladeless fan in one unit covers both seasons
- Touchscreen, remote, timer, and memory settings for daily convenience
- Adjustable louvered vent directs heat where you want it
- Tip-over and overheat protection with a compact footprint
Cons:- Fan-only cooling can’t lower room temperature like a heat pump or AC
- Stated 1,000 sq. ft. coverage is generous for a 1500W unit
Best for: Apartment dwellers who want one compact unit that warms in winter and circulates air in summer
Not ideal for: Buyers expecting real air conditioning — the bladeless fan moves air but won’t actually cool a hot room
- Heating output:1500 watts
- Heating element:Copper PTC infrared
- Heating coverage:Up to 1,000 sq. ft. (manufacturer claim)
- Form factor:Floor cabinet, black
- Controls:Digital touchscreen and remote
- Special features:Bladeless fan, timer, memory setting, adjustable louvers
- Safety features:Tip-over and overheat protection
Our verdict“This pick makes the most sense for small-space residents who’d rather own one dual-purpose unit than two single-season devices.”
Smart Envi Wi-Fi Wall-Mounted Electric Heater
The Envi fills a niche the bigger units ignore: set-it-and-forget-it background heat. At just 500 watts of silent convection heat, it sips power compared with the 1500W JNDRO or EdenPURE GEN21, and because it’s noiseless with a cool-touch exterior, it works in bedrooms and nurseries in ways fan-driven heaters can’t. Smart features are the real differentiator — app scheduling, timer, geofencing, and Alexa or Google Home voice control let a buyer warm a bathroom before their alarm goes off. Freeze protection also makes it a smart pick for cabins, garages, or pipes-prone utility rooms. The tradeoff is raw power: 150 sq. ft. of coverage means it supplements rather than replaces a primary heat source, and unlike the rollable CopperPLUS, it’s permanently wall-mounted once installed.
Pros:- Silent convection heating suits bedrooms and nurseries
- App scheduling, geofencing, and Alexa/Google Home control
- Freeze protection ideal for cabins and pipe-prone rooms
- Cool-touch exterior and child lock for safety
Cons:- 500W output limits it to small spaces as a supplement only
- Wall mounting required, so it can’t move between rooms
Best for: Owners of small rooms, bathrooms, nurseries, or vacation cabins who want silent, schedulable supplemental heat
Not ideal for: Anyone heating more than 150 sq. ft. — 500 watts simply can’t keep a larger room warm on cold days
- Heating method:Convection
- Power:500 watts
- Voltage:120 volts
- Heating coverage:150 sq. ft.
- Temperature range:40–90°F
- Mounting:Wall mount
- Smart home compatibility:Amazon Alexa and Google Home
- Special features:Freeze protection, child lock, cool-touch exterior, overheat protection
- Warranty:3 years
Our verdict“Buy this as a quiet, smart, always-on warmth source for small rooms — not as your main heater.”
HICFM 120V 1500W Wall-Mount Electric Fan Heater with Thermostat
This is the simplest path to permanent supplemental heat in this lineup. Where the DREO Smart Wall Heater adds app control and oscillation, the HICFM keeps things analog: a built-in thermostat, overheat protection with a warning light, and downflow louvers that push warm air toward the floor where it actually matters. That downflow design is a genuine advantage over flat-blowing units, since heat rises anyway and floor-directed airflow evens out room temperature. It covers up to 175 sq. ft., which places it below the DREO’s 215 sq. ft. rating but adequate for bathrooms, home offices, and entryways. The tradeoff is control simplicity — no scheduling, no app, no remote. Renters and anyone without drywall skills should also note this still requires cutting a recessed opening of roughly 9.25 by 11 inches.
Pros:- Built-in thermostat holds a set temperature without babysitting
- Downflow louvers direct heat toward the floor for even room warming
- Overheat protection with a visible warning light
- Recessed design sits nearly flush with the wall
Cons:- Requires cutting a recessed opening in drywall for installation
- No remote, timer, or smart controls of any kind
Best for: Homeowners who want a low-cost, permanently mounted heater for a small bathroom, office, or mudroom and don’t care about smart features
Not ideal for: Renters or anyone wanting app scheduling and voice control — the DREO Smart Wall Heater covers similar space with far more flexibility
- Heating capacity:1500 watts (5120 BTU)
- Voltage:120 volts
- Coverage:Up to 175 sq. ft.
- Mounting type:Wall mount, recessed
- Installation opening:9.25 in wide × 11.125 in tall
- Dimensions:4.4 × 10.8 × 12.2 in (D × W × H)
- Weight:12.9 lb
Our verdict“A no-frills, flush-mounted workhorse for small rooms where permanent heat matters more than features.”
DREO Smart Wall Heater, 1500W, White
This model stands out as the most connected heater in this batch. App scheduling, Alexa and Google Home voice control, a 24-hour timer, and a thermostat adjustable in 1°F increments put it a generation ahead of the HICFM fan heater, which offers none of that. The 120° oscillation is the real differentiator: compared with the larger DREO smart heater’s fixed 30° manual tilt, this one actively sweeps warm air across the room, making it noticeably better for oddly shaped bedrooms or nurseries where one corner always stays cold. The dimming display and quiet forced-air operation are clearly aimed at sleepers. At 215 sq. ft. of coverage, it handles mid-size rooms better than the HICFM too. The compromises are the same as any wall-mounted unit — you’ll need to drill, and it’s strictly an indoor appliance.
Pros:- 120° oscillation spreads heat across the full room, not one spot
- App, remote, Alexa, and Google Home control with scheduling and a 24-hour timer
- 1°F thermostat precision for stable overnight temperatures
- Drilling template and mounting accessories included
Cons:- Requires permanent wall installation with drilling
- Indoor use only and limited to moderate room sizes
Best for: Tech-comfortable buyers who want to pre-warm a bedroom from their phone or by voice and appreciate wide oscillation for even coverage
Not ideal for: Anyone unwilling to drill into walls, or those heating open living areas beyond roughly 215 sq. ft.
- Power:1500 watts
- Heating coverage:215 sq. ft.
- Heating method:Forced air, PTC ceramic
- Temperature range:41°F to 95°F, 1°F increments
- Oscillation:120°
- Control:DREO app, remote, Alexa, Google Home
- Timer:24 hours
- Voltage:120 volts
Our verdict“The smartest small-room pick here for buyers who want app schedules and sweeping heat coverage without stepping up to a mini-split.”
DREO Smart Electric Wall Heater for Indoor Use, Works with Alexa, Large Room
This is the pick when a single wall heater needs to back up a whole open floor plan. Its rating as supplementary heat for up to 750 sq. ft. dwarfs the 215 sq. ft. coverage of the smaller DREO Smart Wall Heater, and it gets there with serious airflow — 11.5 ft/s — while staying whisper-quiet at 28 dB, matching the listed noise floor of the far pricier Comfort Temps mini-split. The ECO mode with temperature calibration helps keep running costs in check on mild days. Unlike its sibling, oscillation here is a manual 30° tilt, so you set it and forget it rather than getting automatic room sweeping. Flame-retardant housing, overheat protection, and an IP24 rating add peace of mind. Just remember: supplementary means exactly that — in a poorly insulated 750 sq. ft. space, expectations should be tempered.
Pros:- Supplementary coverage rated up to 750 sq. ft.
- 28 dB operation is quiet enough for bedrooms and media rooms
- ECO mode with temperature calibration trims energy use
- Flame-retardant housing, overheat protection, and IP24 splash resistance
Cons:- Requires wall mounting with drilling
- Manual 30° oscillation limits directional coverage compared with motorized units
- Real-world performance depends heavily on room insulation
Best for: Owners of open-plan homes who want quiet, app-controlled supplemental heat to take the load off a central furnace
Not ideal for: Buyers who need a primary heat source for a large room — a mini-split like the Comfort Temps is the right tool there
- Heating system:PTC ceramic
- Airflow:11.5 ft/s
- Noise level:28 dB
- Oscillation:30° manual
- Controls:Remote, DREO app, Alexa voice
- Safety:Flame-retardant materials, overheat protection, IP24
- Primary coverage:150 sq. ft.
- Supplementary coverage:750 sq. ft.
Our verdict“The strongest wall-mounted option here for boosting heat across a large space quietly and efficiently.”
Comfort Temps 12,000 BTU Ductless Mini-Split AC and Heat Pump with Wi-Fi
This is the only product in this batch that heats and cools, and that changes the math entirely. A 12,000 BTU inverter heat pump covering 400–550 sq. ft. at 20.5 SEER2 will run dramatically cheaper per BTU than any 1500W resistance heater here — the DREO and HICFM units max out around 5,100 BTU and every watt goes in as heat. You also get a 7-speed fan, 4-way swing, dehumidification, auto defrost, a smart pan heater for cold climates, and Wi-Fi with geolocation and voice assistants. The 16.4 ft. pre-charged line set and included installation hardware soften the setup burden, but this is not a DIY appliance: refrigerant balancing legally and practically calls for a certified HVAC technician, and you’re mounting an outdoor condenser. Buyers comparing this to the DELLA Serena 18,000 BTU should weigh capacity against room size before deciding.
Pros:- Year-round heating and cooling in one system with cold-climate defrost features
- 20.5 SEER2 inverter efficiency far cheaper to run than resistance heaters
- Wi-Fi app with geolocation plus Alexa and Google Assistant
- Pre-charged line set and installation components included with 5-year parts warranty
Cons:- Refrigerant balancing requires a certified HVAC technician
- Needs space and mounting for an outdoor condenser unit
Best for: Homeowners replacing window units or adding climate control to an addition, garage conversion, or sunroom who can hire an HVAC pro
Not ideal for: Renters and DIY-only buyers — the outdoor condenser and professional refrigerant handling make it impractical without an installer
- Capacity:12,000 BTU (1 ton)
- Voltage:115 volts
- Efficiency:20.5 SEER2
- Room area:400–550 sq. ft.
- Noise level:28 dB
- Refrigerant:R454B, 16.4 ft. pre-charged line set
- Features:Inverter compressor, 7 fan speeds, 4-way swing, dehumidifier, Wi-Fi, auto defrost
- Warranty:5 years parts and compressor
Our verdict“The right choice when you want permanent, efficient heating and cooling for a whole room rather than a supplemental boost.”
EnviMAX 220V Hardwired Electric Panel Wall Heater, 1000W
If noise is the deciding factor, this is the quietest option in the entire roundup because it has no fan at all. Fanless convection heating means zero blower hum — not even the 28 dB of the DREO models — which is why it earns the bedroom role over the Smart Envi Wi-Fi heater in the same family. The wall safety sensor is a standout: pull the unit off the wall and power cuts instantly, a meaningful safeguard for kids’ rooms. A cool-touch exterior doubles down on that. The catch is installation. Unlike the plug-in DREO heaters, this one needs 220V hardwiring, which usually means an electrician and a dedicated circuit. And with a fixed 90°F temperature setting rather than a true adjustable thermostat, you’re trading precision control for silence and safety. As primary heat for a bedroom or nursery, though, it’s hard to beat.
Pros:- Fanless convection heating is completely silent
- Wall safety sensor cuts power instantly if the unit is removed
- Cool-touch exterior safe around children and pets
- Slim wall-mounted profile frees up floor space entirely
Cons:- Requires 220V hardwired installation, typically by an electrician
- Fixed 90°F temperature setting with no true adjustable thermostat
Best for: Parents and light sleepers who want totally silent, cool-to-the-touch permanent heat in a bedroom or nursery and can hire an electrician
Not ideal for: DIYers on standard 120V circuits — the hardwired 220V requirement and fixed temperature setting rule out casual installs
- Power:1000 watts
- Voltage:220 volts hardwired
- Amperage:4.5 A
- Heating coverage:300–350 sq. ft.
- Heating method:Fanless convection
- Temperature setting:90°F fixed
- Safety:Wall safety sensor, cool-touch exterior, tip-over protection
- Warranty:3 years
Our verdict“The pick for bedrooms and nurseries where absolute silence and safety outrank smart features and precise control.”
EdenPURE GEN70 Infrared Heater with Cooling Fan
The GEN70 suits a reader who wants warmth close at hand rather than a system for heating a home. Its 450W and 950W settings give more control over a desk or small zone than the Dr. Infrared Heater DR-968, which draws up to 1500W. The GEN70 also adds a fan-only mode and side-to-side oscillation, so it can circulate air when heat is not needed. At just 2 pounds and 5 × 5 × 8 inches, it is easy to move between rooms, though its compact scale limits its reach. Enclosed elements, cool-touch housing, overheat protection, and ETL certification are useful safety features. I would skip it as a main heating source: it is designed for personal or zone use, not whole-home comfort.
Pros:- Two heat settings let users choose between 450W and 950W output.
- Fan-only mode and oscillation provide airflow when heat is not needed.
- At 2 pounds and 5 × 5 × 8 inches, it is easy to carry and place.
- Enclosed heating element, cool-touch housing, overheat protection, and ETL certification.
Cons:- Designed for personal or zone heating rather than whole-home heating.
- Lower maximum wattage than the 1500W Dr. Infrared Heater DR-968.
Best for: People who want a lightweight heater for a desk, bedside area, or other small personal zone, with fan-only airflow for warmer days.
Not ideal for: Households seeking a primary heater for a large room or whole home; its compact format is intended for personal or zone heating.
- Heating technology:PTC infrared
- Heat settings:450W and 950W
- Cooling mode:Fan-only
- Oscillation:Side-to-side
- Dimensions:5 × 5 × 8 inches
- Weight:2 lbs
- Safety and certification:Enclosed heating element, cool-touch housing, overheat protection; ETL certified
- Warranty:1 year
Our verdict“Choose the GEN70 for portable warmth and fan airflow in a small personal zone, not as a room or whole-home heating system.”
Goodman 80,000 BTU 80% Efficiency Multi-Speed Single-Stage Upflow/Horizontal Furnace (GR9S800803BN)
The Goodman GR9S800803BN is a central-heating replacement option for homes suited to an 80,000 BTU gas furnace and an upflow or horizontal installation. Its multi-speed ECM motor can adjust airflow, giving it a comfort and noise advantage over a fixed-speed blower. Compared with the 100,000 BTU Goodman GR9S801005CN, this model has lower capacity and a narrower 17.5-inch cabinet, which may fit replacement plans that do not call for the larger unit. The tradeoff is its 80% AFUE efficiency, below higher-AFUE furnace options, and single-stage operation rather than staged heat delivery. It cannot be installed downflow; thermostats and LP conversion kits also require separate purchase. I would match capacity and installation type to the home before choosing it.
Pros:- 80,000 BTU capacity suits replacement plans calling for a mid-capacity gas furnace.
- Multi-speed ECM motor provides airflow control and can support quieter operation.
- 17.5-inch cabinet is narrower than the 21-inch Goodman GR9S801005CN.
- Aluminized steel primary heat exchanger and R32-ready design.
Cons:- 80% AFUE is lower than higher-efficiency furnace options.
- Upflow or horizontal installation only; not suitable for downflow layouts.
- Thermostat and LP conversion kit are sold separately.
Best for: Homeowners replacing an existing gas furnace who need an 80,000 BTU unit for upflow or horizontal installation and value multi-speed airflow.
Not ideal for: Homes requiring downflow installation, higher AFUE efficiency, or a 100,000 BTU capacity; the larger Goodman GR9S801005CN offers more output.
- Model:GR9S800803BN
- Heating capacity:80,000 BTU
- Efficiency:80% AFUE
- Stages:Single-stage
- Motor:Multi-speed ECM
- Cabinet width:17.5 inches
- Installation:Upflow or horizontal; not downflow
- Heat exchanger:Aluminized steel primary
- Refrigerant readiness:R32-ready
Our verdict“Pick this Goodman for an 80,000 BTU upflow or horizontal replacement where multi-speed airflow matters more than high AFUE efficiency.”
HEATIT 35 sq. ft. Self-Adhesive Electric Radiant Floor Heating Mat
The HEATIT mat delivers heat through the floor, making it a different kind of choice from the Goodman GR9S800803BN central furnace or portable space heaters such as the Dr. Infrared Heater DR-968. Its 35-square-foot coverage is suited to a defined indoor area, where warm tile, stone, or wood underfoot is the goal. The self-adhesive fiberglass mesh can be cut to shape around turns, but the heating cable itself cannot be cut, so layout planning matters. At 420W and 12W per square foot, it is a small-area floor-heating solution rather than a whole-home system. It is UL listed for the USA and Canada and has a 30-year limited warranty when installed according to requirements. The tradeoff is installation commitment: it sits beneath flooring, needs a thermostat, and is not for outdoor, pool, or spa use.
Pros:- Provides radiant warmth beneath up to 35 square feet of flooring.
- Self-adhesive fiberglass mesh can be shaped around turns and angles.
- Compatible with ceramic tile, natural stone, and wood flooring.
- UL listed for the USA and Canada, with a 30-year limited warranty under installation requirements.
Cons:- Heating cable cannot be cut, so the floor plan must suit the mat layout.
- Requires a separate thermostat controller.
- Not intended for outdoor, pool, or spa installations.
Best for: Renovators adding radiant warmth beneath flooring in a 35-square-foot indoor bathroom, entryway, or other defined floor area.
Not ideal for: Buyers seeking portable or whole-home heat, or projects where the floor layout cannot accommodate the fixed heating cable.
- Coverage:35 sq. ft.
- Mat dimensions:20 in. wide × 21.3 ft. long
- Voltage and amperage:120 V; 3.5 A

Goodman 100,000 BTU 80% Efficiency Multi-Speed Single-Stage Upflow/Horizontal Furnace (GR9S801005CN)
With 100,000 BTU output, the Goodman GR9S801005CN is the higher-capacity choice beside the 80,000 BTU GR9S800803BN. That added output may suit a larger or higher-demand home when the system design calls for it, while the 21-inch cabinet takes more installation space than its smaller Goodman counterpart. Both are single-stage, 80% AFUE furnaces with multi-speed airflow and upflow or horizontal installation only. This model uses a stainless steel tubular, dual-diameter primary heat exchanger and includes stated parts and unit-replacement warranty coverage, with registration and qualified installation conditions. Its limitations are practical: downflow layouts and California installations are excluded, and accessories such as LP conversion and venting kits are sold separately. I would favor it only when the home’s heating load justifies the extra capacity.
Pros:- 100,000 BTU capacity serves higher heating loads than the 80,000 BTU Goodman GR9S800803BN.
- Multi-speed blower allows airflow adjustment.
- Stainless steel tubular, dual-diameter primary heat exchanger.
- Warranty information includes 10-year parts and unit-replacement coverage, subject to installation and registration conditions.
Cons:- 80% AFUE efficiency is below higher-AFUE furnace options.
- 21-inch cabinet needs more space than the 17.5-inch Goodman GR9S800803BN.
- Not available for California installation and cannot be installed downflow.
- LP conversion and venting kits are sold separately; warranty coverage requires qualified installation and timely registration.
Best for: Homeowners whose heating-load assessment calls for 100,000 BTU and whose installation allows a 21-inch upflow or horizontal furnace.

How We Picked
I compared these systems by the job a buyer needs them to do: heat a single room, add warmth to a fixed area, or serve as part of a whole-home setup. I weighed stated capacity and system type alongside installation demands, controls, placement flexibility, and whether the product also provides cooling. Those differences matter because a high-capacity furnace is not a direct substitute for a portable heater, and a compact floor mat cannot heat an entire home.
The ranking favors options with a clear use case and a strong balance of capability and practical fit. The DELLA Serena leads for its combined heating and cooling role, while the Goodman furnaces rank as whole-home choices for properties already suited to ducted gas heating. Portable and wall-mounted models follow because they offer narrower coverage, and specialized picks such as the HEATIT mat rank for specific spaces. I also considered drawbacks: installation complexity, fixed placement, limited coverage, and the need to match the system to the home’s electrical or fuel setup.
Factors to Consider When Choosing Best Home Heating Systems
Before choosing a system, decide how much of the home needs heat and what infrastructure is already in place. These factors can help narrow the field before comparing individual models.
Match the System to the Area You Need to Heat
Start by identifying whether the problem is a chilly room, an addition, or the whole house. A portable heater can add warmth where people spend time, while a wall heater serves a chosen spot without occupying floor space. Mini splits and furnaces belong in a different decision: they are installed systems whose design and capacity need to suit the building. A common mistake is buying a room heater and expecting it to replace central heat across several rooms. Measure the area and note ceiling height, insulation, and open connections to adjacent rooms before comparing capacity claims. If the cold is limited to one room, sizing a full-home system around that room may add needless complexity.
Check Existing Fuel and Electrical Infrastructure
System compatibility can determine what is practical before performance comparisons begin. A gas furnace requires an appropriate fuel connection and ductwork, while electric wall heaters and radiant mats need suitable circuits and installation locations. Mini splits require outdoor unit placement and a path for refrigerant and electrical connections. Do not assume that a standard outlet can support every permanently installed electric heater; check the product’s voltage, wiring instructions, and local requirements. For hardwired or high-voltage equipment, plan around qualified installation and any needed electrical work. Reviewing the home’s existing services early can prevent choosing a system that requires costly changes.
Compare Heating Capacity With the Home’s Heat Loss
Capacity should be matched to the space’s heat loss, not selected by room size alone. Insulation, drafts, window area, climate, and ceiling height all affect how hard a system must work. An oversized system may cycle frequently or heat unevenly, while an undersized one can struggle during colder weather. Furnace capacity is especially consequential because it serves a larger zone and depends on duct distribution. For localized products, consider whether heat needs to reach one seating area or several parts of a room. A professional load calculation is useful for a permanent whole-home replacement; portable heaters call for more modest expectations.
Think About Installation, Maintenance, and Service Life
A system’s purchase is only one part of its ownership demands. Portable heaters are easy to move but still need safe placement and routine cleaning, while wall-mounted units need a suitable surface and access to their controls. Mini splits and furnaces involve installation, and furnaces also need regular servicing and filter attention where applicable. Radiant floor mats can be disruptive to add after finished flooring is in place, so they are easier to plan during a renovation. Ask who will install the unit, what upkeep it needs, and whether parts or service are accessible in your area. A system that fits the room but is difficult to maintain may be a poor long-term match.
Decide Whether Cooling or Smart Controls Matter
Some buyers benefit from a system that handles more than winter heat. A mini split with cooling can serve through warm weather, which may justify a more involved installation for homes without central air. Wi-Fi and remote controls can make scheduling and adjustments easier, especially for a fixed heater or a system used on a routine. These controls do not make a heater more powerful, and smart features may add setup steps or depend on a stable network. Think about whether remote access will change how you use the system or simply add complexity. If simple manual operation suits the household, prioritize reliable controls and appropriate capacity over app features.
Consider Total Ownership Cost, Not Just the Equipment
Compare the full cost of getting heat into the space: equipment, installation, electrical or fuel work, maintenance, and expected energy use. Operating cost depends on local electricity and fuel rates as well as how much heat the home loses, so a wattage or efficiency figure alone cannot predict a bill. Portable heaters can be inexpensive to deploy in one room but may be inefficient as a substitute for whole-home heating. A heat pump may require more planning upfront while offering both heating and cooling. Ask installers for estimates based on your home and usage pattern rather than relying on generic savings claims. The best choice is the one whose installed and operating costs make sense for the area it will actually heat.
Frequently Asked Questions
Can a portable space heater replace my home’s main heating system?
A portable heater is generally best for adding warmth to a room, not supplying heat throughout a home. Its reach depends on room layout, insulation, and the unit’s capacity, and open doorways can let heat escape. Using several portable heaters as a whole-home plan may place more demand on electrical circuits and requires careful attention to safe placement. If your central system cannot keep up, first check for drafts, blocked vents, or maintenance issues. Choose a portable model when you need supplemental, room-specific heat.
Should I choose a mini split or a furnace for whole-home heating?
The right choice depends on the home’s existing equipment, climate, and how you want heating and cooling delivered. A furnace may fit a home with serviceable ducts and a suitable gas connection, while a mini split can provide heating and cooling without relying on the same duct network. Mini splits need outdoor equipment placement and professional installation; furnaces depend on fuel, venting, and duct distribution. Ask a qualified installer to compare system sizing and expected operating costs for your location. The product capacity alone does not determine which system will heat your home better.
Is a 1,500-watt electric heater enough for a large room?
A 1,500-watt rating does not guarantee comfortable heat in every large room. Results depend on insulation, ceiling height, outside temperatures, drafts, and whether the space opens into other rooms. Treat this class of heater as a room-level or supplemental option and check the manufacturer’s coverage guidance against the room’s actual conditions. If the heater must run continuously to maintain comfort, the space may need better insulation or a system designed for broader coverage. Also confirm the electrical circuit can support the unit as instructed.
Does a wall-mounted heater need a dedicated electrical circuit?
It depends on the model’s voltage, wattage, wiring method, and the capacity of the existing circuit. Some wall heaters plug into a suitable outlet, while others are hardwired or require higher-voltage service. Check the installation manual and have an electrician confirm circuit compatibility before buying a fixed unit. Sharing a circuit with other high-load appliances can cause problems, even if the heater physically fits the wall. This check is especially useful for 220-volt hardwired models and planned renovations.
When does radiant floor heating make sense instead of a room heater?
Radiant floor heating makes sense when comfort at floor level is the priority and the area is defined, such as a small bathroom zone. It warms the surface underfoot rather than moving hot air around the room, so it serves a different purpose from a portable heater. A small mat is not designed to heat a whole house, and its coverage must match the floor area available after fixtures and permanent objects are accounted for. Installation is easiest during a flooring project because adding it later can require removing finished flooring. Consider it an area-specific comfort feature rather than a replacement for the home’s main heat source.
Conclusion
For the best overall balance in this lineup, I would start with the DELLA Serena mini split if you need installed heating and cooling and can accommodate its setup. For a home already configured for ducted gas heat, the Goodman 80,000 BTU furnace is the more relevant whole-home candidate; the 100,000 BTU version makes sense only when the home’s heating load calls for that capacity. The JNDRO wall heater is a straightforward value-minded choice for supplemental room heat, while the Smart Envi Wi-Fi heater suits beginners who want fixed placement and app controls. Choose an EdenPURE or Dr. Infrared portable heater when moving warmth between rooms matters, the HEATIT mat for a small underfoot zone, and the Comfort Temps mini split when its capacity and installation fit your space. Match the system to the area, infrastructure, and installation you can support before choosing a model.
