Mr. Heater MHS30T Double Tank Top Propane Heater Review: The Ultimate Portable Heat Solution?

There’s a specific kind of chill that settles in as the sun dips below the horizon, one that can cut an otherwise perfect evening short. I remember one particular autumn night, huddled around a fire pit with friends. The conversation was flowing, but so was the cold air, seeping through our jackets and making us inch ever closer to the flickering flames. The front of us was toasty, but our backs were freezing. It’s a familiar story for anyone who loves spending time outdoors—on the patio, in the workshop, at a tailgate, or even in a hunting blind. The challenge is always the same: how do you get powerful, targeted heat exactly where you need it without a complicated, permanent, or expensive setup? This dilemma is what sends so many of us searching for a portable, potent, and reliable heating solution. It’s this exact problem that the Mr. Heater MHS30T Double Tank Top Propane Heater promises to solve, and we were determined to see if it lived up to that promise.

What to Consider Before Buying a Patio Heater

A patio heater is more than just an item; it’s a key solution for extending the usability of your outdoor spaces into the cooler months. It transforms a chilly, uninviting patio or deck into a comfortable oasis for relaxation and entertainment. The primary benefit is straightforward: warmth. But beyond that, the right heater provides convenience, portability, and efficiency, allowing you to bring comfort to construction sites, fishing spots, or any outdoor area that needs a blast of heat. Without one, you’re often at the mercy of the weather, forced indoors when you’d rather be enjoying the fresh air.

The ideal customer for this type of product is someone facing the need for powerful, directional, and portable heat in an outdoor setting. This includes homeowners with patios, DIY enthusiasts working in unheated garages or workshops, campers, fishermen, hunters, and contractors on job sites. They value simplicity, raw power, and freedom from electrical cords. Conversely, this type of open-flame, radiant propane heater might not be suitable for those who need to heat an enclosed, unventilated indoor space, as it’s designed for outdoor use only. It’s also not for someone seeking a decorative, ambient heat source like a flame tower. For those users, electric infrared heaters or larger, more aesthetically focused pyramid heaters might be better alternatives.

Before investing, consider these crucial points in detail:

• Dimensions & Space: Consider the heater’s footprint and the area you need to heat. A tank-top model like this one is compact, mounting directly onto a 20 lb. propane tank, saving floor space. However, ensure you have adequate clearance from combustible materials, as radiant heaters get extremely hot at the source.
• Capacity/Performance: Performance is measured in British Thermal Units (BTUs). The 30,000 BTU output of the Mr. Heater MHS30T Double Tank Top Propane Heater is substantial for a unit of its size. Consider if you need variable settings to adjust the heat level and fuel consumption for different conditions, a feature this model offers.
• Materials & Durability: Look for sturdy construction, particularly in the burner heads, safety guards, and mounting bracket. Stainless steel and high-quality metal components resist rust and degradation from high heat. The longevity of the unit often comes down to the quality of these core parts.
• Ease of Use & Maintenance: How easy is the heater to set up, ignite, and shut down? A direct-mount system is typically very straightforward. Models with match-lit ignition are simple and reliable, requiring no batteries or electricity, but they are less convenient than push-button igniters. Long-term care is minimal, usually just involving keeping the burners clean and checking connections.

Understanding these factors will help you choose a heater that not only meets your needs but provides safe, reliable warmth for years to come.

While the Mr. Heater MHS30T Double Tank Top Propane Heater is an excellent choice for portable power, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Unboxing a Utilitarian Powerhouse

Pulling the Mr. Heater MHS30T Double Tank Top Propane Heater from its box, the first impression is one of pure utility. This isn’t a design-centric piece meant to blend into high-end patio furniture; it’s a tool, and it looks the part. The construction feels solid and no-nonsense. The dual burner heads, protected by sturdy wire guards, are the main event, mounted on a robust bracket designed to grip a 20 lb. propane tank securely. At just 6.6 pounds, it’s surprisingly lightweight, reinforcing its portable nature. Assembly is practically non-existent. Our experience mirrored that of many users who noted it was “up and running in a couple of minutes.” You simply screw the heavy-duty bracket onto the heater body (screws are included, though one user reported them missing in a damaged box) and then attach the entire unit to the propane tank. The POL connection is a standard, robust brass fitting that requires a firm hand to tighten properly—a point of confusion for some new users, but a necessary safety feature. Compared to larger, more cumbersome patio heaters, the sheer simplicity and immediate readiness of this unit are its most striking initial features. You can see its compact and functional design for yourself online.

Performance Deep Dive: Putting the Mr. Heater MHS30T to the Test

A heater’s worth is measured in warmth and reliability. We put the Mr. Heater MHS30T Double Tank Top Propane Heater through its paces in various outdoor scenarios, from a chilly open patio to a semi-enclosed workshop, to understand its real-world capabilities, usability, and safety features. This is where the unit truly reveals its character—a blend of raw power and simple, effective design.

Heat Output and Performance: The 30,000 BTU Powerhouse

The headline feature of this heater is its 30,000 BTU maximum output, and we can confirm it is formidable. Firing up both burners on the high setting creates an immediate and intense wave of radiant heat. Standing six to eight feet away, you can feel a distinct, comforting warmth that cuts right through cold air. This isn’t a gentle, ambient heat; it’s a powerful, directional blast that does exactly what it’s supposed to do: warm people and objects directly in its path. We found this incredibly effective for creating a “zone of comfort” on a patio. By swiveling the two heads, we could aim one towards the seating area and another towards the person grilling, effectively doubling its coverage area. One user mentioned it “really kicks out the heat in my hunting blind,” and we can easily see why. Even on the lowest setting of a single burner (10,000 BTU), it provides enough heat to take the edge off in a small, targeted area, making it surprisingly versatile and fuel-efficient. One user confirmed this, noting “minimal propane usage even at highest output levels.” However, it’s crucial to understand the nature of radiant heat. As another user rightly pointed out, if you’re “out in the open with no buffer from wind,” the heater struggles to be effective unless you are very close. Wind is the enemy of radiant heat, and this unit is no exception. In a garage, workshop, or on a patio with at least one wall to block the wind, its performance is stellar. The sheer power and adjustability are what make this a feature that really sets it apart from less powerful options.

Design, Portability, and Setup: Simplicity in Action

Mr. Heater has perfected the art of simple, effective design with the MHS30T. The entire setup process, from unboxing to ignition, took us less than five minutes. The unit mounts directly onto the collar of a standard 20 lb. propane tank, the kind you use for a gas grill. The bracket is sturdy and holds the heater securely, creating a stable, self-contained unit. Its 6.6-pound weight makes it effortless to carry and mount. This grab-and-go portability is a massive advantage. We easily moved it from the back patio to the driveway for a small project, something that would be impossible with a traditional stand-up heater. The swivel heads are not a gimmick; they are a genuinely useful feature that adds a layer of practical functionality, allowing you to direct the heat precisely. The POL connection, which some users struggled with, is a left-hand thread fitting that needs to be tightened firmly with a wrench. One user noted their initial trouble but called the company and was told to push harder, which worked. This tight fit is by design to ensure a leak-proof seal, and once you understand that, it’s a non-issue. The match-lit ignition is another aspect of its simple design. While it lacks the modern convenience of a push-button piezo igniter, it also means there are no electronics to fail, no batteries to replace, and no complex parts to break. It’s a reliable, old-school approach that fits the heater’s rugged, utilitarian ethos. The sheer ease of getting this heater set up and blasting heat is a major selling point.

Operational Nuances and Safety Features

Operating the Mr. Heater MHS30T is intuitive. Each burner has its own control knob with settings for low, medium, and high. You can run one burner or both, giving you incredible control over both the heat output and your propane consumption. On a full 20 lb. tank, Mr. Heater estimates a run time of about 14.5 hours with both burners on high. In our testing, running a single burner on low extended this time significantly, making it an economical choice for longer periods of use. The lighting process is simple: push in and turn the knob to your desired setting, then use a long match or lighter to ignite the burner. The most critical feature, however, is the tip-over safety shut-off. We tested this by carefully tilting the entire unit while it was running. As promised, the moment it reached a significant angle, the fuel flow was instantly cut off, and the flames extinguished. This is a non-negotiable safety feature for any propane appliance, and we were pleased to see it work flawlessly. It provides essential peace of mind, especially when the heater is used in active areas like job sites or family patios. This commitment to safety, combined with its straightforward operation, makes the heater accessible even for those unfamiliar with propane appliances, provided they read and follow the clear instructions.

Durability and Potential Concerns: A Look at Longevity

The overall build of the Mr. Heater MHS30T Double Tank Top Propane Heater feels robust and designed for longevity in outdoor environments. The metal bracket, chrome reflectors, and protective cages are all made from heavy-gauge materials. However, our analysis of user feedback uncovered some legitimate concerns regarding quality control. While the vast majority of experiences are positive, a few users reported serious malfunctions right out of the box. One described a burner making an “ugly noise” before “getting red hot in the back side” and melting plastic. Another mentioned that after less than a year, one side produced a “huge flame” that wouldn’t go away. These incidents, while seemingly rare, are serious and point to potential inconsistencies in manufacturing. We did not experience any such issues during our testing; our unit performed perfectly. However, it’s important for potential buyers to be aware of these reports. The heater comes with a 1-year limited warranty, which should cover such defects. We recommend thoroughly inspecting and testing the unit immediately upon purchase in a safe, outdoor location to ensure both burners are operating correctly, with a clean, controlled flame and no unusual noises or overheating of components behind the reflector shield.

What Other Users Are Saying

Synthesizing feedback from a wide range of users provides a balanced view of the Mr. Heater MHS30T Double Tank Top Propane Heater. The overwhelming sentiment is positive, with many praising its powerful heat output and simplicity. One user summed it up perfectly: “Puts out great heat, easy to install.” Another highlighted its value and efficiency, stating it’s a “Solid value for money. Minimal propane usage even at highest output levels.” The portability is also a frequently mentioned benefit, with one person finding it “Amazing! I used this when I go fishing. Pretty handy I must say.”

However, the feedback isn’t universally glowing. The most concerning comments revolve around product defects and safety. One user had a frightening experience with a brand-new unit where a burner malfunctioned, got red hot, and began to melt plastic components. Another reported a similar issue with large, uncontrolled flames after less than a year of use. These reports, though in the minority, highlight a potential for quality control lapses that buyers should be aware of. Minor issues like a beat-up box or missing mounting screws were also mentioned, suggesting potential issues in the shipping and handling process.

How Does the Mr. Heater MHS30T Compare to the Alternatives?

The Mr. Heater MHS30T occupies a specific niche of raw, portable power. To understand its place in the market, it’s helpful to compare it to other popular outdoor heating solutions that cater to different needs and preferences.

1. Pamapic 48,000 BTU Pyramid Flame Patio Heater

The Pamapic Pyramid Heater is a completely different beast. It prioritizes aesthetics and ambient warmth over directional, portable heat. With a stunning visual of a flame dancing inside a quartz glass tube and a massive 48,000 BTU output, it’s designed to be a centerpiece on a large patio, creating a wide circle of gentle warmth and light. While more powerful overall, its heat is less focused than the Mr. Heater’s radiant output. It’s also large, heavy, and semi-permanent. Someone would choose the Pamapic over the Mr. Heater for entertaining on a stylish deck where visual appeal and 360-degree ambient heat are more important than portability and targeted heating for a workspace or campsite.

2. Briza 1500W Infrared Electric Patio Heater

The Briza Infrared Heater represents the electric alternative. Its 1500W output is equivalent to about 5,100 BTU, significantly less powerful than the Mr. Heater. However, it offers key advantages: it can be used both indoors and outdoors, it produces no fumes, requires no fuel tanks, and can be mounted on a wall, ceiling, or stand. This makes it ideal for enclosed patios, workshops, or garages where using a propane heater would be unsafe. A user would choose the Briza if they have easy access to an electrical outlet, require a heater for both indoor and outdoor use, and prioritize silent operation and zero emissions over the raw power and off-grid portability of the Mr. Heater MHS30T.

3. DR. INFRARED HEATER DR-238 Carbon Infrared Outdoor Heater

Similar to the Briza, the Dr. Infrared Heater DR-238 is an electric option, but it’s built for more permanent, heavy-duty applications like restaurant patios, garages, and decks. It offers three heat settings (900W, 1200W, 1500W) and is designed to be wall or ceiling-mounted, providing consistent, targeted infrared heat. Its key advantage is remote-controlled convenience and a weatherproof design that can withstand the elements. This is a “set it and forget it” solution. Someone would opt for the Dr. Infrared heater if they need a permanent heating solution for a specific outdoor zone and value the convenience of remote operation and the safety of an electric system over the mobile, high-output capability of the propane-powered Mr. Heater.

Our Final Verdict: Is the Mr. Heater MHS30T Worth It?

After extensive testing and analysis, our verdict on the Mr. Heater MHS30T Double Tank Top Propane Heater is overwhelmingly positive, with a few important caveats. This is not an elegant patio accessory; it is a brutally effective and highly portable heating tool. For anyone who needs to blast a significant amount of heat into a specific outdoor area—be it a job site, garage, fishing spot, or patio—its 30,000 BTU output and directional swivel heads are simply unmatched in this form factor. The simplicity of its design, from the direct tank mounting to the match-lit ignition, is a strength, ensuring reliability and ease of use where it matters most.

It is the ideal solution for the user who prioritizes raw power and portability above all else. However, the reports of quality control issues cannot be ignored. While our test unit was flawless, we recommend a thorough inspection upon purchase. If you need a no-fuss, no-frills heat cannon that you can take anywhere, this is hands-down one of the best options available. For its intended purpose, it delivers exceptional performance and value.
