It uses a windproof USB lighter for ignition and includes a shut-off valve and tip-over safeguard. The design emphasizes portability and straightforward operation, making it suitable for temporarily heated greenhouse bays or patios where quick heat boosts are needed.
Mr. Heater Original Tank Top Radiant Heater
This multi-directional radiant heater mounts to a 20 lb propane tank, offering a range of BTU outputs (45,000–36,000–30,000) via its regulator. It is designed for easy portability, with a focus on direct, focused heat for targeted spaces within a greenhouse or work area. A tip-over safety switch helps prevent accidents, making it a practical option where space is at a premium but robust heat is needed.
Cuisinart Portable Tabletop Patio Heater
With 11,000 BTU, this compact table-top heater warms up to 30 square feet and uses a reflector top plate to distribute heat evenly. Built-in safety features include an anti-tilt automatic shut-off and a burner screen guard, allowing tabletop use in patios or sheltered greenhouse sections. Its portable design makes it ideal for supplemental warmth at bench stations or small work zones inside a greenhouse.

The Avenger FBDTP30 provides infrared warmth with 30,000 BTU output, designed for quick heat rise in outdoor areas or greenhouses. It features adjustable heat direction up to 45 degrees, a safety shut-off valve, match-light ignition, and a safety tip switch to shut down if tipped. This model balances portability with focused, radiation-based warmth for faster comfort in cooler zones of a greenhouse or patio setup.
Buying Guide
- Space and BTU needs: Larger greenhouses require higher BTU units with even heat distribution. Consider whether you need radiant, forced-air, or infrared warmth for your space.
- Ignition and safety: Pulse or match-light ignition options affect startup reliability. Look for tip-over switches, overheat protection, and automatic shut-off on power loss for safety compliance.
- Portability vs. stability: Tabletop and compact models offer portability for small zones, while larger floor-standing units stay put in bigger spaces. A stable base and durable housing extend lifespan in humid greenhouse environments.
- Fuel and maintenance: Propane availability, regulator quality, and hose connections influence performance and maintenance. CSA or UL certifications provide added assurance for safety standards.
- Heat distribution: Radiant setups heat objects and plants directly; forced-air units spread warmth more broadly, which can be advantageous for entire greenhouse bays. Infrared pans heat quickly with targeted warmth and lower air movement.
- Quiet operation: If the space is occupied by plants sensitive to heat or people working nearby, consider units designed for quieter startup and operation.
- Installation considerations: Ensure proper ventilation in enclosed greenhouses when using propane heaters. Follow manufacturer guidelines for clearance from combustibles and secure mounting where applicable.
When selecting a propane heater for a greenhouse or workshop, align BTU capacity with space size, decide on heat delivery type, and prioritize safety features and certification. The options listed above cover a range of use cases from portable warmth to large-area coverage, helping users maintain comfortable conditions in cooler seasons without compromising safety.
