Mr. Heater MHS30T Double Tank Top Outdoor Propane Heater (F216600)

Check Price on Amazon

This double tank-top heater head features two independently operated swivel burner heads and adjustable heat output between 10,000 and 30,000 BTU. Each burner can be controlled separately to direct heat or conserve fuel when partial coverage is sufficient. The swivel heads allow for directional heating which is useful on patios or around seating areas.

Key technical points: the unit mounts directly to a standard 20 lb propane tank, the two burners provide flexibility for targeted heating, and the adjustable settings allow you to match output to conditions. As a tank-top style assembly, it is primarily for outdoor use and requires proper ventilation and stable mounting on the cylinder.

Mr. Heater MH540T 540-Degree 45,000 BTU Radiant Tank Top Portable Propane Heater

Check Price on Amazon

The MH540T is a high-output tank-top radiant heater head that offers up to 45,000 BTU with three adjustable power levels (45,000 / 36,000 / 30,000 BTU). Its design includes a 360° burner paired with a 180° swivel bracket, described as “540° radiant coverage,” to warm people and objects directly rather than just heating the air.

Safety features include a tip-over shutoff switch. The assembly is designed to mount on a standard propane cylinder and is intended for outdoor events like tailgating, sporting events, and porches. Because of its higher output, it is suited to larger open areas and situations where quick heat is needed.

Avenger FBDTP30 Infra-Red Tank Top Outdoor Heater, Double Burner

Check Price on Amazon

The Avenger FBDTP30 is a double-burner infrared tank-top heater head with three heat settings and swivel burners capable of up to 45° directional adjustment. It connects to a standard propane tank and is designed for portable outdoor heating for camping, patios, and similar use.

Notable attributes include a front and rear wire guard for operator safety, an automatic safety control valve that shuts off gas if the flame goes out, and a tip switch to stop operation if the unit tips. Its match-light ignition does not require electricity, which can be useful in off-grid settings.

elysia 46,000 BTU Patio Heater Burner Head Replacement Assembly

Check Price on Amazon

This replacement burner assembly targets patio heater owners needing a durable upgrade or repair. Constructed from 304 stainless steel with a double-cover burning mesh design, the assembly prioritizes corrosion resistance and extended service life.

Features called out include stainless fasteners, upgraded thread interfaces for structural stability, and an included adjustment knob and ignition button that are CSA certified. The unit is described as fitting specific pole dimensions (noted as 2.55″ pole fit), so confirming compatibility with your heater model and pole diameter is essential before purchasing.

Generic 3″ Pole THP-Burner Fast Start Tall Heater Complete Assembly

Check Price on Amazon

This complete burner head assembly is for tall patio heaters and includes a piezo electric igniter (battery required), control knob, and a design intended to replace several tall heater models. It’s marketed as a fast-start, non-pilot unit to modernize older heaters or repair failed burners.

Key considerations include verifying fit with your heater’s pole diameter and model numbers listed by the manufacturer. The presence of an electric igniter offers a convenience upgrade over match-light systems, but battery installation and compatibility should be checked during installation.

Buying Guide: How To Choose The Right Propane Heater Head

Selecting the appropriate propane heater head involves matching output, safety features, compatibility, and intended use. Below are practical considerations to compare models and assemblies.

1. BTU Output And Coverage

BTU indicates heating power. Lower-output heads (10,000–30,000 BTU) are suited to small seating areas and directional heating. High-output heads (30,000–45,000+ BTU) deliver heat for larger open spaces. Consider whether you need radiant heat for people and objects or convective heat for air volume.

2. Burner Configuration

Options include single, double, and 360° burner designs. Double burners and swivel heads allow directional control and partial operation to conserve fuel. 360° or wide-coverage heads are better for centrally located, multi-person spaces.

3. Mounting Type And Compatibility

Tank-top assemblies mount directly to a standard 20 lb propane cylinder. Replacement burner heads and tall heater assemblies often require matching pole diameters and model fitment. Verify physical dimensions and mounting threads before purchasing to avoid incompatibility.

4. Materials And Durability

Stainless steel components and corrosion-resistant hardware increase longevity for outdoor use. Look for solid brass valves, stainless fasteners, and protective guards to minimize degradation from weather and heat cycles.

5. Ignition System And Controls

Ignition types include match-light, piezo electric, and electronic/trigger. Electronic igniters and piezo systems simplify operation, while match-light can be reliable off-grid. Adjustable control knobs, flame locks, and pressure regulators improve flame stability and user control.

6. Safety Features

Essential features include tip-over shutoff, flame-out safety valves, and heat shields. For replacement parts, confirm that valves and controls meet relevant safety certifications (CSA, etc.) and that protective guards are present to prevent burns and accidental contact.

7. Intended Use And Portability

For camping and tailgating, choose lightweight, compact tank-top heads with match-light or reliable igniters. For permanent patio installations or frequent entertaining, consider durable replacement assemblies and high-output units with wider radiant coverage.

8. Fuel Efficiency And Flame Control

Models with adjustable flame control and multi-stage settings allow fuel conservation and better temperature management. Pressure regulators and consistent ignition systems help maintain flame stability and efficient burn rates.

9. Ease Of Installation And Maintenance

Tank-top heaters typically require minimal tools, while replacement burner assemblies may need disassembly of the heater top and pole. Check whether batteries are needed for igniters and whether replacement parts (igniter button, knob, or burner mesh) are available.

10. Compatibility With Outdoor Conditions

Consider wind exposure, rain, and salt air. Look for protective guards, heat shields around hose connections, and weather-resistant finishes. Some designs include top and bottom heat guards to prevent component overheating and protect surfaces.

Comparison Perspectives

When comparing models, weigh the following perspectives:

• Performance vs. Portability: High-BTU units provide rapid warmth but are bulkier and consume more fuel. Tank-top doubles give flexibility with moderate portability.
• Safety vs. Convenience: Electronic ignition and flame sensors add convenience; mechanical safety switches provide passive protection. Choose a balance aligned with usage patterns.
• Replacement vs. Full Unit: Replacing only the burner can be cheaper and extend life, but ensure fit and certification. Buying a full, matched assembly reduces fitment risk but may be pricier.
• Material Longevity vs. Initial Cost: Stainless components and brass valves cost more upfront but reduce long-term maintenance and replacement frequency.

Use the above considerations to match the heater head to your space, expected usage, and maintenance preferences. Confirm model fitment and safety certifications before purchase or installation.
