Greenworks 60V Cordless Patio Heater
Best OverallPros
- Excellent heat output for its size
- Works with all Greenworks 60V batteries
- Quiet operation with no fumes
Cons
- Battery and charger sold separately
- Not as effective in windy conditions
The Greenworks 60V Cordless Patio Heater is the most popular model in the lineup, offering 48,000 BTUs of heat from a compact, portable unit. It uses the same 60V battery platform as Greenworks lawn mowers and leaf blowers, making it a natural addition for existing users. Owner reviews consistently praise its ability to warm a 10x12 foot patio area for up to two hours on a single 4.0Ah battery.
This model features a 360-degree heat reflector that distributes warmth evenly, and the integrated tip-over switch adds safety. The main drawback is that the battery and charger are not included in the base price, which increases the initial investment for new users. However, for those already in the Greenworks ecosystem, this is a seamless upgrade.
Greenworks 80V Commercial Patio Heater
Best for Large PatiosPros
- Highest heat output in the range
- Wider heat radius for larger areas
- Commercial-grade build quality
Cons
- Heavier and less portable
- Shorter runtime than 60V models
The Greenworks 80V Commercial Patio Heater is designed for larger outdoor spaces, delivering 60,000 BTUs with a 15-foot heat radius. It uses the high-capacity 80V 8.0Ah battery, which provides about 1.5 hours of runtime on the highest setting. This model is built with a heavier gauge steel frame and a larger reflector head, making it suitable for commercial patios or large residential decks.
Owner reviews note that it performs well even in light breezes, though it is significantly heavier than the 60V model. The 80V battery platform is less common than the 60V, so replacement batteries are more expensive. It is best for users who prioritize maximum heat output over portability and runtime.
Greenworks 40V Compact Patio Heater
Best for Small SpacesPros
- Longest runtime of any model
- Lightweight and easy to carry
- Uses affordable 40V batteries
Cons
- Lower heat output limits coverage
- Not suitable for large groups
The Greenworks 40V Compact Patio Heater is the smallest and lightest in the lineup, making it ideal for balconies, small patios, or camping trips. It produces 30,000 BTUs and runs for up to three hours on a single 4.0Ah battery. The compact design includes a folding base and a carry handle, so it is easy to store and transport.
Owner reviews highlight its impressive runtime and low weight, though some note that the heat radius is limited to about 8 feet. It is best for individuals or couples who need targeted warmth for a small seating area. The 40V battery platform is more affordable than the 60V or 80V systems, making this a budget-friendly entry point into cordless heating.
Greenworks 60V Tower Patio Heater
Best Design & CoveragePros
- Tall tower design for better heat distribution
- Longer runtime than standard 60V model
- Stylish appearance for modern patios
Cons
- Bulky and harder to store
- More expensive than the standard model
The Greenworks 60V Tower Patio Heater features a tall, cylindrical design that stands 6.5 feet high, providing heat at a higher elevation for better distribution around the patio. It produces the same 48,000 BTUs as the standard 60V model but offers a slightly longer runtime of 2.5 hours due to a more efficient heating element. The tower design also includes a built-in timer and three heat settings.
Owner reviews appreciate the modern look and the even heat distribution, though some find it bulky to move around. The taller design makes it less stable in strong winds compared to the lower-profile models. It is a good choice for users who want a permanent-looking heater that blends with outdoor furniture.
Greenworks 80V Portable Patio Heater
Best for Camping & TravelPros
- Compact and portable with carry case
- Runs on powerful 80V battery
- Good heat output for its size
Cons
- Short runtime on high setting
- 80V batteries are expensive
The Greenworks 80V Portable Patio Heater is designed for on-the-go use, featuring a compact form factor that fits into a carry case. It produces 40,000 BTUs and runs for about one hour on the highest setting using an 80V 8.0Ah battery. This model is ideal for camping, tailgating, or heating a small area away from home.
Owner reviews note that it is easy to pack and set up, but the runtime is limited compared to other models. The 80V battery platform provides more power but at a higher cost. It is best for users who already own 80V Greenworks tools and want a portable heating option for outdoor adventures.
What to check before buying a Greenworks patio heater
Battery platform compatibility is the most important factor. Greenworks offers 40V, 60V, and 80V systems, and each requires its own battery and charger. If you already own Greenworks tools, choose a heater that uses the same voltage to avoid buying new batteries. Heat output, measured in BTUs, determines how large an area the heater can warm. A 30,000 BTU heater covers about 8 feet, while a 60,000 BTU model covers up to 15 feet. Runtime varies by battery capacity and heat setting, so consider how long you typically use the heater in one session. Weight and portability matter if you plan to move the heater around your garden or take it on trips. Safety features like tip-over switches and cool-touch handles are standard on all Greenworks models.
Mistakes to avoid when buying a cordless patio heater
One common mistake is buying a heater without checking the battery ecosystem. If you buy a 60V heater but only own 40V tools, you will need to purchase a new battery and charger, which can cost as much as the heater itself. Another error is underestimating heat output needs. A 30,000 BTU heater is fine for a small balcony but will not warm a 12-foot patio. Buyers also overlook wind exposure. Cordless heaters work best in sheltered areas, as wind can dissipate heat quickly. Finally, do not ignore runtime. If you host long gatherings, choose a model with at least 2 hours of runtime on the highest setting, or buy a second battery to swap out.
