Why Martin Wall Heaters Are the Best on the Market
Key Takeaways
- Martin Wall Heaters balance affordability, efficiency, and durability, with models from 8,000 to 20,000 BTU covering rooms of various sizes
- Martin's piezo ignition and self-powered millivolt thermostat need no electricity at all, unlike Rinnai's models, which require continuous power and shut off gas during an outage
- Mounting a Martin heater is manageable DIY work, but the propane or natural gas connection itself needs a licensed professional
- Mr. Heater's Vent-Free Blue Flame and the Rinnai EX38CTN both offer higher BTU output for larger rooms, at the cost of either reduced durability or a higher price and electrical dependency

Choosing the right wall heater matters for keeping your home warm and comfortable. With plenty of options out there, Martin stands out for striking a strong balance between price and performance. There are cheaper alternatives and more powerful ones, but a Martin Propane Heater gives you a genuinely solid combination of both.
Understanding Wall Heaters
Wall heaters earn their popularity through space-saving design and efficient heating, without eating into your floor space. They come in electric, gas (propane or natural gas), and occasionally oil-powered versions.
Electric wall heaters run indefinitely as long as the power stays on, but that's also their main limitation: no grid power means no heat. Gas wall heaters, propane especially, are a common choice for off-grid living, mobile homes, and anywhere reliable electricity isn't guaranteed, typically with stronger heat output than a comparable electric unit.
Why Choose Martin Wall Heaters?
Energy Efficiency Martin Wall Heaters run at roughly 80% efficiency, keeping fuel costs reasonable while delivering solid heat output, generally more efficient than a comparable electric wall heater per dollar of operating cost.
Solid Heating Capacity With models ranging from 8,000 to 20,000 BTU, Martin's lineup covers rooms of different sizes, producing warm air quickly and distributing it evenly without an oversized price tag.
Safety Features Safety centers on sealed direct-vent combustion, which keeps the flame from ever touching room air, backed by overheat protection and an oxygen depletion sensor. Since the unit is permanently wall-mounted, there's no tip-over risk to design around in the first place.
Durable and Reliable Built from quality materials for a long service life. Mounting is manageable DIY work, but the gas connection should be completed by a licensed professional. Maintenance needs are minimal once installed.
Types of Wall Heaters
Propane Heaters Highly efficient and effective for larger spaces. Tank-fed, which makes them a strong fit for off-grid living or anywhere without reliable electricity, with robust heating and no grid dependency.
Natural Gas Heaters Connected directly to a utility gas line for consistent, cost-effective heat. A great fit for homes that already have natural gas service, well suited to whole-room or whole-home heating.
Electric Wall Heaters Simple and common. Smaller models may plug into a standard outlet, while higher-wattage units typically need a dedicated hardwired circuit. Good for heating individual rooms where running gas isn't practical.
The Best Wall Heaters Compared
Martin Propane Direct Vent Thermostatic Heater (20,000 BTU)
This heater warms both small and large spaces efficiently and evenly, connecting directly to a propane tank outside your home. Mounting the unit is manageable for a confident DIYer, but the propane line connection itself needs a licensed gas fitter. Since it doesn't need any electricity to run, it doubles as a genuinely useful emergency heater during power outages.
Mr. Heater Vent-Free Blue Flame (30,000 BTU)
This model offers a higher heating capacity, suited to larger rooms, with straightforward installation and decent safety features. Efficiency runs a bit lower than Martin's direct-vent models, and being vent-free, it releases combustion byproducts into the room, so proper ventilation and a working CO detector matter more here than with a sealed direct-vent unit.
Rinnai EX38CTN (38,400 BTU)
A powerful heater capable of covering a large room, with strong efficiency, user-friendly controls, and solid safety features. It costs more than the alternatives here, and unlike Martin's models, it requires continuous electrical power to run the igniter and fan, meaning it will shut off gas during a power outage. That's worth factoring in if backup heat reliability matters to you.

Frequently Asked Questions
Does propane have more heat per gallon than other fuels?
No, propane actually has fewer BTUs per gallon than heating oil (roughly 91,500 vs. 138,500 BTU per gallon). What makes propane appealing isn't raw energy density, it's tank-based portability, no need for a utility line, and reliable performance without electricity.
Can I install a Martin wall heater myself?
Mounting the unit is manageable for a confident DIYer using the included hardware. The gas connection itself, propane or natural gas, should be completed by a licensed professional to meet code and manufacturer requirements.
Which of these heaters works during a power outage?
Martin's propane and natural gas models both run on piezo ignition with no electrical connection needed, so they keep working through an outage. The Rinnai EX38CTN requires continuous power and will shut off gas if the power goes out.
Conclusion
Martin Wall Heaters offer a strong blend of efficiency, solid heating capacity, sealed-combustion safety, and low maintenance. Whether you need to heat a single room or want a reliable backup for power outages, they're a dependable choice. Mr. Heater's Vent-Free Blue Flame and the Rinnai EX38CTN both step up in raw BTU output for larger rooms, the trade-off being either reduced durability or a higher price with electrical dependency.
