LifeSmart Infrared Quartz Heater
Type: Infrared Quartz; Power: 1500W. This unit is designed and marketed for coverage up to 1500 square feet and uses multiple infrared elements to distribute radiant heat.
The heater includes 6 infrared tube elements and caster wheels for mobility. Heat settings include high, low, and eco modes and the unit ships with a remote for temperature and timer adjustments.
Key attributes referenced in the product listing are targeted coverage for larger areas, ease of handling via metal casters, and variable power settings for energy management. Infrared elements provide direct radiant heating, often perceived as comfortable warmth for occupants and objects rather than relying solely on air circulation.

Type: Dual (Infrared Quartz + PTC); Power: 1500W. The Dr Infrared model combines infrared tubes with PTC ceramic heating for a broader heat profile.
The product highlights a dual heating system that aims to deliver up to 60% more heat than single-method units and lists coverage for a large room. It includes a high/low energy setting, a 12-hour auto shut-off timer, tip-over and overheat protection, and a quiet blower (claimed low decibel level).
Features of interest for large-space use include the combined technologies for both radiant and convective heating, a remote control for convenience, and safety cutoffs. The listed high pressure low noise blower supports circulation to help distribute heat across larger footprints.
LifeSmart Electric Tower Heater
Type: Infrared Quartz Tower; Power: 1500W. This tower-style heater uses infrared elements arranged in a vertical form factor to distribute heat and save floor space.
The listing emphasizes efficient and equal heat distribution via infrared heating technology and includes programmable heat settings and two remote controls. The tower design is intended to integrate into living areas while offering multiple programmable options for scheduled operation.

For larger rooms or open-plan areas, the tower format can provide steady radiant heat and convenience controls, though circulation-based spread may be enhanced by pairing with a ceiling fan or using doorways to promote airflow.
Heat Storm Phoenix HS-1500-PHX
Type: Infrared; Power: 1500/750W selectable. This model combines compact size with wall-mount or floor placement options and patented HMS technology intended to leverage ambient humidity for soft heat.
Manufacturer features include a patented heat exchanger with HMS Technology, two power modes, removable feet for floor use, and wall-mounting capability. The grill is described as safe to touch, indicating surface safety measures.
For coverage considerations, infrared heaters like this provide targeted radiant warmth and can be installed on a wall to free floor space and direct heat toward occupied zones. Removable feet allow flexible placement depending on room layout and heat distribution needs.
Dreo Space Heater
Type: PTC Ceramic; Power: 1500W. This PTC ceramic model emphasizes rapid heating and wide-angle oscillation for better room coverage.
Listed features include fast heating with Hyperamics Tech, 70° oscillation to spread warmth, a 12-hour timer, remote control, and a range of safety systems (tip-over, overheat protection, auto-off, flame-retardant materials). The product indicates effective coverage for rooms up to 250 square feet per its feature set, but the oscillation and quick warm-up are designed to improve perceived coverage.
PTC ceramic heaters typically excel at quick convective warming of air and can be useful when paired with strategic placement to circulate heat into adjacent spaces. Safety certifications (listed ETL in the feature set) are commonly used as a reliability indicator.
Buying Guide: Choosing An Electric Heater For 1500 Square Feet
Sizing and technology selection are key for a space around 1500 square feet. No single 1500W portable heater will reliably heat an entire 1500 sq ft open plan to uniform temperatures when used alone; practical deployment often involves multiple units or a higher-capacity HVAC solution. The guide below helps evaluate options by perspective.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Coverage And Realistic Expectations
- Rated Coverage vs. Real Coverage: Manufacturers sometimes state ideal coverage with optimal insulation and closed doors. Expect lower effective range in high ceilings, poor insulation, or open layouts.
- Single Unit Limits: A 1500W portable unit typically serves a large room or a 1-2 zone setup effectively, but not a full 1500 sq ft open area uniformly.
Heating Technology Comparison
- Infrared Heaters: Radiant heat warms people and objects directly; effective for spot heating and rooms where occupants remain in specific areas. Good for rooms with drafts where convective heat would be lost.
- PTC Ceramic Heaters: Provide fast convective heating, ideal for quickly warming the air in a room. Oscillation and fans help distribute warmth.
- Dual Systems (Infrared + PTC): Combine radiant and convective benefits to address both object and air temperature, often improving perceived coverage.
Placement And Distribution Strategies
- Multiple Units: For open-plan 1500 sq ft spaces, consider two or more strategically placed 1500W units to create overlapping warmth.
- Elevation And Direction: Wall-mounted infrared models can direct heat to occupied zones; tower or floor units with oscillation help spread warm air.
- Airflow Assistance: Use ceiling fans on low reverse or small circulation fans to move warm air from source to other parts of the room.
Energy Use And Controls
- Variable Power Modes: Two-stage or eco modes let you reduce wattage during milder conditions to save energy.
- Thermostat And Timer: Programmable thermostats and timers maintain setpoints and reduce runtime, improving comfort efficiency.
- Remote Control & Scheduling: Remote operation improves convenience and encourages efficient use by turning units off when not needed.
Safety And Certifications
- Overheat & Tip-Over Protection: Essential safety features for portable units; verify these protections are listed.
- Material And Surface Safety: Look for flame-retardant housings and cool-touch grills for areas with kids or pets.
- Third-Party Listings: ETL, UL, or similar listings indicate independent safety testing and are preferred.
Noise, Maintenance, And Durability
- Noise Level: Blowers increase circulation but can add noise; infrared-only units are typically quieter.
- Filters & Cleaning: Some units require occasional dusting of elements or filters for optimal performance.
- Build Quality: Steel-bodied or well-vented plastic designs differ in longevity for garage/workshop vs. living-room use.
Cost-Effectiveness And Use Cases
- Supplemental Heating: Portable electric heaters are best used as supplemental heat for occupied zones rather than whole-home replacements for large floor areas.
- Workshops And Garages: Rugged forced-air heaters with steel bodies are suitable for intermittent use in colder non-living spaces.
- Living Spaces: Infrared and dual-heat systems offer more comfortable low-oxygen-safe warmth for living rooms and bedrooms.
Comparative Checklist Before Buying
- Verify the manufacturer’s claimed coverage and compare to your room layout and insulation.
- Decide between radiant (infrared) and convective (PTC ceramic/forced air) based on whether you need spot heat or air warming.
- Confirm safety features and third-party certifications.
- Consider portability, mounting options, and how many units may be necessary to meet comfort goals.
- Review control options: thermostat, remote, timer, and power modes for energy management.
