A cool evening should not require a trip for a propane refill. For a patio with a suitable electrical supply, Powerscale CozyRay 300 and CozyRay 600 offer a convenient way to bring adjustable infrared warmth to the seats you use most.
Electric and propane patio heaters both have a place outdoors. The useful comparison is not simply which one feels hotter. It is how you want to set up your space, control the heat, and prepare for the next evening outside.
Electric or propane: the quick answer
For a fixed patio seating area with suitable electrical power, Powerscale CozyRay 300 and CozyRay 600 offer 1500W infrared heating, four heat levels, touch and remote controls, and no propane refills. Propane can suit locations without convenient electrical access or applications requiring a higher-output heater.
A 1500W CozyRay uses 18 kWh over 12 hours at full power: approximately $3.30 at $0.1831/kWh. At $3.99/gallon, the assumed 20,000 BTU/h and 46,000 BTU/h propane examples cost about $10.47 and $24.07 for 12 hours. These are different-capacity examples, not equal-heat comparisons; local rates and settings change the result. See the calculations and price sources.
The main difference: electricity or a fuel tank
CozyRay 300 and CozyRay 600 use electricity to produce infrared heat. A propane patio heater burns fuel supplied by a cylinder. That difference changes the routine: electric heating requires a suitable power supply, while propane heating requires fuel checks, cylinder handling, and replacement or refilling.
For a regular dining spot or reading corner, removing the fuel-tank task can make outdoor heating easier to fit into everyday life. If your seating area is far from a suitable electrical supply, a propane model may offer more placement flexibility, subject to its instructions.

1. Skip propane refills and fuel storage
An empty cylinder can interrupt an otherwise simple evening. With CozyRay, there is no propane supply to check before guests arrive, no cylinder to exchange, and no spare fuel tank to store for heating.
This is a practical advantage for people who use the same outdoor space regularly. Once the heater is correctly installed and connected, the routine centers on choosing your heat setting rather than managing fuel.
2. Adjust the warmth without leaving your seat
Both CozyRay models provide four adjustable heat levels, with touch and remote control. Use the remote to change the setting as the evening cools, or use the touch controls when safely accessible.
That convenience matters at a dinner table, during a conversation, or when you are settling down with a book. Propane controls differ between models, so compare the actual features rather than assuming every fuel-burning heater operates the same way.
3. Keep more room for chairs, tables, and guests
A freestanding propane heater commonly occupies floor space for its base and fuel cylinder. A wall- or ceiling-mounted CozyRay installation can leave more of that floor area available for furniture and movement.
Plan the installation around the seating area and follow the model’s mounting instructions and required clearances. Wall mounting does not remove clearance requirements. If you prefer a tripod arrangement, confirm compatibility; the stand is sold separately.
4. Bring quick infrared warmth to the place you use
Both CozyRay 300 and CozyRay 600 offer up to 1500W of infrared heating. Powerscale lists a 2.5-second heat-up time for both models. This describes the heater’s response, not the time needed to warm an entire patio.
Infrared heat warms people and surfaces in its path. For a defined seating area, that makes positioning especially useful: aim the heater toward the area where people will sit. Distance, wind, outdoor temperature, and installation all affect the warmth you feel.
Propane heaters also deliver radiant heat, and some have substantially higher heat output. CozyRay’s appeal is convenient, adjustable spot heating; the same unit should not be assumed to replace every larger gas heater across an entire patio.
How CozyRay delivers warmth—and how propane patio heaters differ
CozyRay: electricity → heating element → infrared waves → people and surfaces. CozyRay 300 and 600 use electric heating elements to emit infrared electromagnetic waves. When your clothing, skin or nearby objects absorb that radiation, the absorbed energy becomes heat. You can feel radiant warmth without first raising the temperature of all the air around your seat.
Propane patio heaters: burning fuel → hot gases and heated emitter → convection and radiation. Burning propane heats gases and nearby air, which rise and mix with the surroundings. It also heats the burner or emitter surfaces; those hot surfaces radiate infrared energy toward people and objects. The balance between radiant and convective heat depends on the heater design. Propane patio heaters do not work only by warming air.
Why direct infrared warmth is useful on a breezy patio
Moving air carries away the portion of heat stored in warmed air. CozyRay’s directional infrared transfer does not depend on keeping that warm air around your chair: energy travels directly to surfaces within its path. This is a practical benefit compared with heaters that rely mainly on warming air.
Better suited to open patios than heating the air alone. CozyRay 300 and 600 deliver infrared warmth directly to people and objects within their heating path. On a breezy patio, this direct heating offers an advantage over relying mainly on warm air that can drift away.
5. Avoid fuel-leak and combustion risks at the heater
CozyRay 300 and CozyRay 600 operate without a propane cylinder, gas hose, or fuel-burning flame. That removes propane-leak and combustion-exhaust hazards from the heater itself, giving you a practical safety advantage in these specific areas.
Propane heaters burn fuel and require attention to fuel connections, ventilation, and placement. Incomplete combustion can produce carbon monoxide. The U.S. Consumer Product Safety Commission explains this risk; outdoor propane patio heaters must not be brought indoors.
Electric heating still involves hot surfaces and electrical risks. Correct installation, clearances, and operation remain essential. This comparison concerns fuel-related hazards, not a claim that every electric heater is safer in every situation.
No propane fuel odor or combustion exhaust
With CozyRay, there is no propane fuel to leak and no burner producing combustion exhaust. For a seating or dining area, that means warmth without a propane-related fuel smell from the heater.
A strong gas smell is not normal operation to tolerate. Propane is odorized to help people detect leaks, and the Propane Education & Research Council advises never ignoring that smell. If you suspect a leak, leave the area and contact your propane supplier or emergency services from a safe location. Carbon monoxide itself has no smell.
Properly operating propane heaters should not be described as always producing a severe odor. Likewise, electric heating cannot guarantee the absence of every smell; dust or residues may cause odors. CozyRay’s specific advantage is the absence of propane fuel and combustion at the heater.
What does IP65 add?
Both CozyRay models carry an IP65 rating: dust-tight construction and protection against water jets under the rating’s test conditions. It is a useful feature for an outdoor installation, but it does not mean the heater can be submerged or that every outlet and connection is weather-protected. Follow the product’s installation and electrical requirements.
What does 12 hours of heating cost?
At continuous full rated input for 12 hours, one CozyRay 300 or 600 uses 18 kWh, costing approximately $3.30 at $0.1831/kWh. A 46,000 BTU/h propane heater uses approximately 6.03 gallons, costing $24.07 at $3.99/gallon before tax.
These are examples for different-capacity heaters, not equal heat output or equal comfort. The large propane heater has roughly nine times the energy input of a 1500W electric heater; the 20,000 BTU/h example has about four times the input.
| Heater | Product price* | Energy used in 12 hours | 12-hour energy cost |
|---|---|---|---|
| CozyRay 300 · 1500W | $129.99 | 18 kWh | $3.30 |
| CozyRay 600 · 1500W | $129.99 | 18 kWh | $3.30 |
| Large propane · 46,000 BTU/h | $89.99 | Approximately 6.03 gallons | $24.07 |

About the 20,000 BTU/h example
**The smaller propane calculation assumes a 20,000 BTU/h fuel input for 12 hours: approximately 2.62 gallons at $3.99/gallon, or $10.47 before tax. This is an assumed comparison capacity, not the specification of the pictured tabletop heater. The comparison uses an assumed purchase price of $79.99. The calculation uses refill pricing, not disposable-cylinder retail pricing.
Calculation and price sources
Electricity: 1.5 kW × 12 hours × $0.1831/kWh = $3.30. Large propane: 46,000 BTU/h × 12 hours ÷ approximately 91,500 BTU/gallon × $3.99/gallon = $24.07. Small propane fuel equivalent: 20,000 × 12 ÷ 91,500 × $3.99 = $10.47. Calculations use unrounded consumption values.
The electricity benchmark is the EIA July 2026 U.S. residential average of 18.31 cents/kWh. The refill-price example is U-Haul South Montgomery’s $3.99/gallon plus tax, checked October 16, 2026. These are a national electricity benchmark and one local refill quote, not your specific tariffs. The propane energy conversion is approximate.
These examples cover 12 operating hours only. Lower settings and local prices change the result. Energy costs exclude equipment, installation, refillable cylinders, refill travel and propane sales tax. Actual electrical charges depend on your bill. Choose a heater configuration that meets your comfort needs before comparing costs.
