Greenworks vs Ryobi Patio Heater: Which Cordless Heater Is Better?
Both Greenworks and Ryobi offer cordless patio heaters powered by their respective 40V battery platforms. These heaters are ideal for decks, patios, and camping where a gas tank or electrical outlet is not convenient. The key differences lie in heat output, runtime, and the value of the battery ecosystem you may already own.
Ryobi's 40V heater generally produces more heat (15,000 BTU vs 12,000 BTU) and offers three heat settings versus Greenworks' two. This gives Ryobi an edge for larger spaces or colder evenings. Greenworks, however, is often priced lower and is a solid choice for those already invested in their 40V system for lawn tools.
Heat Output and Coverage
Ryobi's 15,000 BTU output is noticeably stronger, capable of warming a 150 sq ft area. Owner reviews consistently note it feels warmer at a greater distance. Greenworks' 12,000 BTU is adequate for a 100 sq ft space, making it suitable for a small patio or direct personal heating. If you need to heat a larger gathering area, Ryobi is the clear winner.
Runtime and Battery Compatibility
Both heaters run on 40V batteries, but they are not cross-compatible. Ryobi claims up to 4 hours on low with a 4Ah battery, while Greenworks claims up to 3 hours. In practice, runtime depends on the heat setting used. Ryobi's three settings offer more flexibility to conserve battery on milder days. Neither heater includes a battery, so factor in the cost of a starter kit if you are new to the platform.
Build Quality and Portability
Both heaters feature a similar tower design with a metal stand. Ryobi's build feels slightly more robust, with a wider base for stability. Greenworks is lighter (8 lbs vs 9 lbs), making it slightly easier to move. Both are rated for outdoor use but should be stored indoors when not in use. Ryobi's 5-year warranty is a year longer than Greenworks' 4-year coverage.
What to Check Before Buying a Cordless Patio Heater
- Battery Ecosystem: If you already own 40V tools from Greenworks or Ryobi, buying the matching heater saves on battery costs.
- Heating Area: Measure your patio or deck. Ryobi is better for areas over 100 sq ft.
- Runtime Needs: Consider how long you typically use the heater. A larger battery (6Ah or more) will extend runtime for both models.
- Heat Settings: More settings give you better control over warmth and battery life.
Mistakes to Avoid
- Ignoring battery cost: A heater without a battery is useless. Factor in the price of a battery and charger if you are starting fresh.
- Overestimating coverage: Cordless heaters are less powerful than gas models. Do not expect to heat a large open area on a windy night.
- Forgetting wind: Both heaters are less effective in strong winds. Position them in a sheltered spot for best results.
