10 Best Garage Heaters for Winter (July 2026) Reviewed
A garage heater turns a cold, unused bay into a place where you can work on a car, lift weights, build furniture, or simply get a vehicle ready without numb hands. The best garage heaters for winter match the space, the insulation level, and the power or fuel setup already available in your garage.
My short answer is that a hardwired 240V heater makes the most sense for a garage used often, while a portable propane or infrared model fits occasional or targeted warmth. A big output number alone is not the whole answer: drafts, ceiling height, open doors, ventilation, and where you stand all change the result.
Contents
I reviewed the verified product specifications, stated coverage, safety features, ratings, and review patterns for all 10 options below. The list includes forced-air electric models, direct-warming infrared heat, and propane units, so a compact attached workshop and a large, well-ventilated work building are both covered.
Start by measuring length times width, then note whether the ceiling and garage door are insulated. That small bit of homework prevents the common mistake of expecting a small 120V heater to heat a drafty two-car garage like a powerful 240V or high-BTU unit.
Top 3 Picks for Best Garage Heaters for Winter (July 2026)
These category picks give the quick answer first: InoKraft is my leading electric choice for a mid-size garage, VEVOR is the practical hardwired pick for a smaller shop, and TEMPWARE is the higher-coverage ceiling-mount option. Read the individual reviews before choosing, because the circuit requirement and intended space matter as much as the heater itself.

1. InoKraft 7,500W is the best overall electric garage heater for a mid-size space
InoKraft 7,500W Electric Garage Heater, Wire: 8 AWG, Plug...
7,500W 240V
750 sq ft stated coverage
40-99F thermostat
Pros
- 7
- 500W output
- Remote and timer
- ECO mode
- Five adjustable louvers
- Wall or ceiling mount
Cons
- 31.25A circuit needed
- 65 dB may be noticeable
- Installation is not simple
The InoKraft is the electric garage heater I would put first for a regularly used one- or two-car workspace that has the right 240V supply. Its 7,500W output, stated 750-square-foot coverage, digital 40°F to 99°F thermostat, and remote make a well-rounded feature set.
The thermostat range matters when you want a modest holding temperature rather than full heat all day. Its ECO mode and one- to 24-hour timer give you more control over when the fan runs, which is more useful than relying on a simple on-off heater.
This unit directs forced air through five adjustable louvers and can go on a wall or ceiling. I like that flexibility for aiming heat at a bench or across a vehicle bay, but its reported 65 dB noise level means it will be noticeable during quiet tasks.
At 31.25 amps with a NEMA 14-50P plug and specified 8 AWG wire, this is not a casual extension-cord appliance. Have the circuit, wiring, and mounting plan checked by a qualified electrician before buying.
The electrical requirement makes this heater best for a prepared garage
Choose it when your garage can support a dedicated 240V, high-amperage connection and you want heat frequently. The required electrical work may outweigh its advantages for a renter, a detached shed with only 120V outlets, or a space used a few weekends a year.
The airflow control makes this heater useful for a working layout
Point the louvers away from stored finishes, sawdust piles, and other combustible materials, then let the fan move warmth across open floor area. In a woodworking shop, clean the intake area regularly because forced air can move dust as well as warm air.
2. VEVOR 5,000W is the best value hardwired heater for a compact shop
VEVOR Electric Garage Heater, 5000 Watt Digital Fan Forced...
5,000W 240V
17,064 BTU
538 sq ft stated coverage
Pros
- ETL certified
- Two power levels
- Remote control
- 2F temperature stability
- Adjustable louvers
Cons
- Hardwired only
- 65F maximum setting
- Smaller stated coverage
The 5,000W VEVOR is the sensible answer for a smaller garage, hobby room, or defined work zone where a giant heater would be unnecessary. Its listed 17,064 BTU output and 538-square-foot coverage line up with a compact, reasonably insulated workspace rather than a large open building.
I rate its temperature precision highly for the category because the listing specifies 2°F stability and two power levels. The remote also means you can adjust the heater from your work area instead of walking beneath a wall- or ceiling-mounted unit.
The steel body, overheat shutoff, adjustable louvers, and ETL certification are reassuring details. It is an indoor hardwired model, so treat the mounting location and electrical connection as a permanent installation, not something to relocate with the seasons.
One limitation deserves a clear callout: the maximum stated temperature setting is 65°F. That is a fine comfort target for many garages, but it is less appealing if you expect a very warm exercise room or spend long periods seated at a desk.
The 538-square-foot rating makes this heater a compact-space match
Use this VEVOR for a single-bay garage, an insulated work corner, or a small shop with ordinary ceiling height. For a drafty two-car garage, move up in capacity or improve door seals and insulation first rather than asking this heater to close a large heat-loss gap.
The hardwired design makes installation the first decision
A 240V hardwired connection calls for a planned electrical installation. Mount it where the louver path is clear, maintain the manufacturer’s required clearances, and use a qualified electrician for the circuit work.
3. TEMPWARE 7,500W is the best ceiling-mount option for wider stated coverage
TEMPWARE 7500W Electric Garage Heater, 240V Hardwired...
25,590 BTU
1,250 sq ft stated coverage
240V hardwired
Pros
- Wide stated coverage
- 45-95F thermostat
- Two heat settings
- 12-hour timer
- ETL steel build
Cons
- Hardwired installation
- Remote batteries absent
- Limited speed choices
The TEMPWARE 7,500W model is the stronger electric candidate when floor space is valuable and the garage is larger than a compact shop. It claims 25,590 BTU and up to 1,250 square feet of coverage, plus a ceiling-mount form that keeps the unit above tools, tires, and vehicles.
Its thermostat spans 45°F to 95°F, while the two heat settings run at 6,250W and 7,500W. That low setting can be useful during moderate weather or when you need to maintain rather than quickly raise the temperature.
The remote, 12-hour timer, adjustable louvers, variable mounting angle, steel construction, overheat sensor, and ETL certification address the things I look for in a fixed garage heater. The listing does not include a power cord, which is consistent with its hardwired design.
Its 4.3 rating across 68 reviews is credible but not as strong as the leading 4.6-rated electric choices in this group. I would choose it for its stated coverage and mounting format, not because it has the deepest review history.
The ceiling mount keeps this heater out of the active work zone
A ceiling location is useful when every wall hosts cabinets, shelving, or a workbench. Aim the adjustable louvers diagonally across the longest clear path so the warm stream has distance to mix before it reaches where you stand.
The stated 1,250-square-foot coverage fits an insulated larger garage
That number is most realistic with a closed, insulated garage door and reasonable air sealing. A detached building with exposed framing, high ceilings, or frequent door openings may need more output than the product’s stated area suggests.
4. Mr. Heater 60,000 BTU is the best high-output propane choice for well-ventilated work areas
Mr. Heater 60,000 BTU Forced Air Propane Space Heater with...
30,000-60,000 BTU propane
10 ft hose and regulator
Adjustable angle
Pros
- High variable output
- Hose and regulator included
- Adjustable tilt head
- Portable 14 lb body
- Glove-friendly handle
Cons
- Outdoor use only
- Needs propane tank
- Requires ventilation
This Mr. Heater unit is the powerful portable option for a well-ventilated job site, barn, warehouse, or workshop setting rather than a sealed attached garage. The verified listing specifically labels it for outdoor use, and that limitation is the deciding safety fact.
Its output adjusts from 30,000 to 60,000 BTU, which gives far more quick-heat capacity than the small electric units here. The included 10-foot hose and regulator, adjustable heating angle, 14-pound body, and large handle make setup and repositioning more manageable.
The 4.7 rating from 126 reviews is the highest rating in this collection. Review data points to strong satisfaction with heating power and variable output, although the researched stock status was temporarily unavailable.
Do not mistake output for permission to use a fuel-burning heater in an enclosed space. Propane combustion requires the ventilation and operating conditions in the product instructions, and a carbon-monoxide alarm is a sensible extra layer of protection where it is appropriate.
The outdoor-use designation makes ventilation non-negotiable
This is not the heater to run in a closed residential garage simply because it is cold. Choose it only for a setting that meets the product’s outdoor-use direction and has the airflow needed for propane equipment.
The variable BTU range makes this heater useful for changing conditions
Use the lower setting when a well-ventilated workspace needs a smaller temperature lift and the higher setting for a faster warm-up. The adjustable head helps direct heat toward the active work area instead of wasting it on an empty corner.
5. VEVOR 18,000 BTU is the most flexible portable propane cabinet heater
VEVOR Propane Heater, 6000 to 18000 BTU Propane Cabinet...
6,000-18,000 BTU propane
450 sq ft stated coverage
Three heat modes
Pros
- Three BTU settings
- Up to 73-hour stated runtime
- Wheels with locks
- Tip-over protection
- Low-oxygen and flameout protection
Cons
- Tank not included
- Few reviews
- Radiant heat is directional
The VEVOR cabinet heater is a portable propane answer for someone who wants three output levels rather than one fixed blast of heat. It runs at 6,000, 12,000, or 18,000 BTU and has a stated 450-square-foot coverage area, placing it in the small-garage or targeted-zone category.
Five rolling wheels, including two lockable ones, make it easier to move closer to the work area and roll aside afterward. The published runtime reaches up to 73 hours from a 20-pound propane tank, although real runtime will vary with heat setting and conditions.
Its low-oxygen, tip-over, and flameout protections, zero-pressure gas shutoff, and piezoelectric ignition provide a stronger safety feature list than many basic portable units. Even so, the propane tank is separate and the operating location still needs to follow the manufacturer’s ventilation directions.
I see this model as a good fit for intermittent work rather than a fixed heating system. With only 36 reviews behind its 4.6 rating, the rating is positive but represents a smaller pool than the more established infrared option below.
The cabinet format makes this heater easy to position near the task
Radiant propane heat is useful when you want warmth near a bench, vehicle side, or seated work spot. Lock the wheels after placing it on a stable, level surface and keep the front face clear of people, materials, and traffic routes.
The safety features still require careful propane habits
Built-in protections are not a substitute for reading the manual, checking the hose and connection, and providing the required ventilation. Never treat an indoor/outdoor claim as a reason to ignore local rules or combustion safety.
6. DR. INFRARED HEATER DR-298 is the best 120V infrared heater for direct warmth
DR. INFRARED HEATER Portable Infrared Indoor and Outdoor...
900W,1200W,1500W
120V carbon infrared
Freestanding or mounted
Pros
- Standard 120V power
- Three mounting options
- Carbon infrared element
- Timer and remote
- Tip-over protection
Cons
- Lower 1
- 500W ceiling
- Direct heat is localized
- 4.3 average rating
The DR. INFRARED HEATER DR-298 is the strongest fit when a standard 120V outlet and direct, personal warmth matter more than raising the air temperature throughout a large garage. Its carbon infrared element radiates heat toward people and objects, which feels different from a fan-driven shop heater.
It has three power settings at 900W, 1,200W, and 1,500W, a 50°F to 90°F temperature range, remote control, timer, and stated coverage of 400 square feet. The 90% reflective mirror aluminum reflector is designed to direct more radiant output forward.
Mounting is unusually flexible: freestanding, wall-mounted, or ceiling-mounted. A weighted base with wheels supports portable use, while rust-resistant aluminum housing and ETL-listed tip-over and over-temperature protection support its intended indoor or outdoor versatility.
The evidence base here is broad, with 6,082 reviews and a 4.3 average rating. I would not treat the 1,500W output as whole-garage heat for a cold, leaky two-car building, but it can make a garage gym, detailing bay, or workbench much more comfortable.
The infrared element makes this heater best for people and work zones
Infrared warmth reaches the person in front of it without waiting for all the cold air in the room to heat. That makes this format appealing for short tasks, but it will not distribute warmth behind vehicles, cabinets, or large obstacles like a forced-air unit can.
The standard outlet makes this heater easier to place than a hardwired model
A 120V connection can simplify the electrical side, provided the outlet and circuit are suitable for the load and the manual’s instructions are followed. Keep cords out of driving paths and do not use a damaged outlet or an unsuitable extension setup.
7. Riseon 7,500W is the feature-focused electric option with touchscreen control
7500W Electric Garage Heater with Remote, 240V Hardwired...
7,500W 240V
25,590 BTU
1,250 sq ft stated coverage
Pros
- ECO mode
- Remote and touch controls
- Three operating settings
- Four louver sets
- ETL steel body
Cons
- Hardwired only
- Indoor use only
- 3.9 average rating
The Riseon 7,500W heater competes directly with other ceiling-mounted 240V units but adds an LED touch screen alongside remote control. Its stated maximum is 25,590 BTU for up to 1,250 square feet, with 7,500W high heat, 6,250W lower heat, and a fan-only option.
The ECO mode uses a precision temperature sensor, while the timer runs from one to 12 hours. Four sets of adjustable louvers and a multi-angle mounting bracket offer a lot of control over where the forced air goes, which can help when a garage has one cold exterior wall.
Heavy-duty steel, ETL certification, a built-in thermostat, and automatic overheat power cut-off are meaningful specifications. It is still an indoor hardwired unit, so its installation is a permanent electrical project and needs a qualified electrician.
The caution is its 3.9 average rating from 50 reviews, lower than several similarly sized electric heaters in this roundup. I would choose Riseon if the double-control arrangement and ECO mode are your priorities, while weighing that smaller and less favorable review record.
The control options make this heater convenient at a mounted height
The touchscreen is handy when you are near the unit, and the remote is more practical once the heater is mounted overhead. A scheduled timer can also stop a heater from running longer than a planned work session.
The review record makes this heater a considered rather than automatic choice
Its specifications are competitive, but ratings should influence a close decision between otherwise similar models. Compare the stated circuit needs, coverage, controls, and customer feedback before making this your long-term workshop heater.
8. GASLAND Flame Jet is the best propane heater for a very large ventilated workspace
GASLAND Flame Jet 125,000 BTU Propane Force Air Heater...
75,000-125,000 BTU propane
3,100 sq ft stated coverage
10 ft hose
Pros
- Largest stated coverage
- Variable 75k-125k BTU
- CSA certified
- Electronic ignition
- Hose and regulator included
Cons
- Ventilation required
- Propane tank separate
- Single speed setting
The GASLAND Flame Jet is the high-capacity choice for a large, properly ventilated workspace where smaller electric models will not be enough. Its 75,000- to 125,000-BTU range and stated 3,100-square-foot coverage are far beyond a typical residential portable heater.
Despite that output, the listed body weighs 13 pounds and includes a 10-foot propane hose and regulator. Electronic ignition, an adjustable heat angle, overheat detection, a thermo-electric safety valve, and CSA certification create a substantial safety and handling package for this format.
The listing estimates about five hours of runtime on low with a standard 20-pound tank. Plan fuel logistics before a long job, especially in cold weather when a propane tank can be inconvenient to exchange or refill.
Its 4.4 rating is based on 30 reviews, so I see it as a specialized tool with a limited review base rather than a universal garage recommendation. It belongs in a barn, warehouse, construction site, or big workshop that meets its ventilation needs, not in an enclosed residential setting.
The 125,000-BTU peak makes this heater a large-building tool
Use this scale of output only when the building volume, layout, and ventilation justify it. A small one-car garage can overheat quickly, and a large flame-jet style heater needs more clearance awareness than a compact ceiling-mounted electric unit.
The propane setup requires fuel planning and safe placement
Set the tank and hose where they cannot be struck by vehicles, pinched by a door, or exposed to hot discharge. Follow all product instructions and local requirements, and do not operate fuel-burning equipment without the ventilation it requires.
9. Dura Heat EWH5510 is the focused 240V choice for a 600-square-foot garage
Dura Heat EWH5510 Electric Forced Air Heater with Remote...
17,060 BTU
600 sq ft stated coverage
240V hardwired
Pros
- 45-99F thermostat
- Remote and timer
- Steel body
- Wall or ceiling bracket
- Adjustable grills
Cons
- 30A hardwired circuit
- One speed
- 3.9 average rating
The Dura Heat EWH5510 is a straightforward 240V forced-air heater designed for a garage or workshop around its stated 600-square-foot coverage. Its 17,060 BTU output puts it close to the VEVOR 5,000W unit in capacity, but it pairs that output with an adjustable 45°F to 99°F thermostat.
The remote with LED display, 12-hour timer, adjustable grills, and included wall/ceiling bracket cover the basic daily-use requirements. Its insulated steel body, scratch-resistant construction, spiral-wrapped steel coil, and overheat shutoff indicate that the unit is intended for permanent shop duty.
The major practical detail is the 240V, 5,000W, 30-amp hardwired installation. There is no plug, and the review information also notes that professional installation is required, so put circuit capacity ahead of the product selection.
With a 3.9 average from 27 reviews and some durability complaints reported in the research, it is not my first recommendation when other highly rated choices fit the same space. It remains a viable option when its thermostat range, steel construction, and mount format match your needs.
The 600-square-foot rating makes this heater appropriate for a defined garage size
It makes the most sense for a normal-height, reasonably insulated one-car garage or compact workshop. If your garage is a two-car footprint, has tall ceilings, or loses heat through an unsealed door, select more capacity or reduce the heat loss first.
The adjustable grills make airflow direction part of the setup
Aim the grills across the working area rather than directly at paint, fuel, cardboard, or close-range materials. A wall mounting position can work well if a ceiling mount would send hot airflow straight into storage shelves.
10. TURBRO GH10K Smart is the best Wi-Fi electric heater for a large connected garage
TURBRO 10,000W Electric Garage Heater, 240V Hard Wired, WiFi...
10,000W 240V
34,129 BTU
Wi-Fi plus remote controls
Pros
- Wi-Fi app control
- 1
- 200-2
- 000 sq ft stated coverage
- 10
- 000W output
- ETL listed
- Adjustable louvers
Cons
- 60A circuit required
- Large fixed mount
- 3.9 average rating
The TURBRO GH10K Smart is the high-output electric pick for a large garage where remote preheating is a real benefit. Its 10,000W, 34,129-BTU output has stated coverage from 1,200 to 2,000 square feet, and Wi-Fi control joins a physical panel and remote.
That connected control addresses a common garage complaint: arriving to a cold shop and waiting for it to become usable. Set a 45°F to 95°F temperature target and one- to 12-hour timer, then use the adjustable louvers and mounting angles to direct forced air across the room.
The ETL listing, integrated thermostat, and overheat auto shut-off are welcome, but this is a serious electrical load. The specifications call for a single-phase 240V supply, a 60-amp circuit breaker, and 6 AWG wire, which means professional installation is a prerequisite.
Its 3.9 rating is based on 26 reviews, and the large physical dimensions need room in the chosen mounting location. I would reserve it for a large, frequently used workshop or garage where its output and app control solve an actual problem.
The Wi-Fi control makes this heater useful for planned preheating
Remote control is most useful when you have a predictable arrival time and want to warm the space before starting a project. It does not remove the need for safe placement, clear airflow, or a properly sized circuit.
The 60-amp requirement makes electrical capacity the deciding factor
Check your electrical panel and have a licensed electrician determine whether the required circuit and wire size are practical. If that work is not suitable, a 5,000W or 7,500W model may be a more realistic fixed-heater route.
Garage heater buying starts with heat loss, power access, and safe placement
The right garage heater is sized for the space you actually have, not the space you wish the garage were. Before selecting a model, record square footage, ceiling height, insulation, door condition, available voltage, and whether the garage is attached to the home or is a separate work building.
Garage size needs a BTU estimate that accounts for insulation
BTU, or British thermal unit, describes heat output. For a quick planning range, an insulated garage in a moderate winter climate often needs roughly 20 to 30 BTU per square foot, while a drafty or uninsulated garage may need around 40 to 60 BTU per square foot or more in severe conditions.
A 400-square-foot insulated garage: Plan roughly 8,000 to 12,000 BTU as a starting range.
A 400-square-foot uninsulated garage: Plan roughly 16,000 to 24,000 BTU or more, depending on climate and ceiling height.
A 600-square-foot insulated garage: Plan roughly 12,000 to 18,000 BTU as a starting range.
A 600-square-foot uninsulated garage: Plan roughly 24,000 to 36,000 BTU or more.
Those ranges are planning guidance, not an engineering calculation. Tall ceilings, bare concrete, air leaks, a frequently opened overhead door, and extreme outdoor temperatures all push the required output higher.
An insulated garage benefits most from a thermostat-controlled electric heater
An insulated and air-sealed garage holds heat long enough for a hardwired 240V forced-air heater to work efficiently as a regular source of warmth. The InoKraft, TEMPWARE, Riseon, Dura Heat, VEVOR, and TURBRO models all fit this category if their circuit requirements match your panel.
Before adding output, close the large heat-loss paths. Weatherstripping the overhead door, adding a bottom seal, insulating the ceiling, and addressing major wall gaps can reduce the workload placed on every heater.
An uninsulated garage needs either more capacity or targeted heat
For a cold, uninsulated garage, choose a larger heater than the same floor area would need when insulated, or heat the person and bench rather than the whole air volume. The DR. INFRARED HEATER is a direct-warmth option, while a high-output propane heater may suit a properly ventilated large work area.
Do not run a fuel-burning heater in a closed garage merely to overcome drafts. Improve the building shell where possible, then choose a heater whose fuel and ventilation directions fit the building.
Electric and propane heaters suit different patterns of use
Electric heaters are the cleaner choice for an enclosed garage when a correctly sized circuit is available. They do not create combustion gases at the point of use, and a thermostat, remote, or timer can make frequent heating more controlled.
Propane heaters provide high output and portability, which can be useful in large, open, well-ventilated work areas or occasional job-site use. They also require fuel supply management, proper ventilation, and strict adherence to manufacturer instructions.
Forced air and infrared distribute warmth in different ways
A forced-air garage heater warms room air and can spread heat across a larger open area, especially from a ceiling mount with adjustable louvers. The tradeoff is audible fan noise and the possibility of stirring dust, an issue regularly raised by woodworking and detailing users.
Infrared heat warms objects and people in its path. It is well suited to a workbench, exercise area, or a person standing at one side of a garage, but it has a more localized effect than a fan heater.
Heater placement needs a clear path and manufacturer clearances
Place a fixed heater high enough to keep it away from impacts, but not where its airflow immediately meets a wall, storage rack, or garage door. Aim the warm stream across the open part of the room, ideally along the longer dimension, so it circulates before it reaches your work area.
Keep combustible products, gasoline containers, solvents, cardboard, sawdust, curtains, and vehicle covers outside the clearance distances listed in the manual. Never cover a heater, block its intake, or dry clothing directly on it.
Electrical work and combustion safety are part of the heater decision
Hardwired 240V models require the correct breaker, wire gauge, disconnecting method, and installation practices for the unit and local electrical code. A licensed electrician can verify the circuit and mounting method; that is a much better choice than treating a high-wattage heater as a simple plug-in device.
For propane units, follow all manual requirements for use location, ventilation, tank handling, hose inspection, and shutoff. Maintain working smoke and carbon-monoxide alarms where appropriate, and check local building, fire, and permit requirements before a permanent installation.
FAQs
What is the best heater for an uninsulated garage?
The best heater for an uninsulated garage is one with enough output for the added heat loss, or an infrared model that warms the work zone directly. Improve door seals and insulation first when possible. For a large, properly ventilated workspace, a high-output propane model may work; for an enclosed garage, a correctly installed 240V electric heater is usually the simpler choice.
How many BTU do I need to heat a 2-car garage?
A typical two-car garage is often about 400 to 600 square feet. Start around 20 to 30 BTU per square foot if it is insulated, or roughly 40 to 60 BTU per square foot if it is uninsulated, then add capacity for tall ceilings, severe cold, air leaks, and frequent door opening.
Are electric garage heaters worth it?
Electric garage heaters are worth it when you use the garage regularly, have a suitable 240V circuit, and want thermostat-controlled heat without combustion gases at the heater. A hardwired forced-air unit is especially practical in an insulated workshop. A 120V infrared model is better for direct warmth in a limited area than for heating a whole drafty garage.
What is the safest garage heater?
The safest garage heater is one that is correctly sized, installed, and used according to its manual. In an enclosed garage, a properly installed electric model with overheat protection and a thermostat avoids combustion gases. Keep required clearances, never block airflow, and use propane only where its ventilation and location directions are met.
How do I size a garage heater for my space?
Measure the garage floor area, note ceiling height and insulation, then use a planning range of about 20 to 30 BTU per square foot for insulated space or 40 to 60 BTU per square foot for uninsulated space. Increase the estimate for drafts, high ceilings, extreme cold, and regularly opened garage doors. Match the result to a heater’s stated output and installation requirements.
The InoKraft is the best all-around garage heater choice for 2026
For a frequently used, mid-size garage with the right 240V electrical supply, I would start with the InoKraft 7,500W for its thermostat range, ECO mode, remote, and directional louvers. For a larger insulated space, TEMPWARE or TURBRO adds coverage, while the DR. INFRARED HEATER is the better choice for direct warmth from a standard outlet.
The best garage heaters for winter are the ones that match your building, circuit, and safe operating conditions. Measure the garage, address major drafts, and choose the model whose output and installation requirements you can support safely.
