Martin Propane Heater Review | Everything You Need to Know

• Built-in thermostat. Most wall heaters include one to hold a constant room temperature.
• Adjustable heat. Propane models let you dial in the exact heat level you want.
• Heavy-duty grill. A quality wall heater often uses durable materials like die-cast aluminum for safety and longevity.
• Glass-ceramic window. Some models include one for a view of the flame and added aesthetic appeal.
• Piezo ignition. Common on propane heaters for easy, reliable starts with no electricity required.

A built-in thermostat reduces thermal swings throughout the day.

Generally needs less upkeep than other heating systems.

A modern look that complements most room decor.

Piezo ignition means the heater runs through outages.

Martin's direct-vent system puts the heat it produces to use in the room rather than losing it to the venting process, cutting down on wasted fuel. The built-in thermostat holds a steady temperature without constant manual adjustment, which also conserves fuel.

Propane burns cleaner than oil or coal, which helps reduce a home's overall combustion footprint. Even heat dispersion across the room means you're less likely to need a second heating device to cover cold spots.

Unlike a bulky standalone heater, a wall-mounted unit installs directly onto an exterior wall, freeing up floor space entirely, a real advantage in smaller rooms. The fireplace-style design adds a genuine aesthetic touch rather than just functioning as equipment.

The included installation manual makes the process manageable even for someone with modest DIY experience. The compact footprint doesn't come at the cost of performance, with strong heat dispersion and a heavy-duty grill for durability.

The upfront cost of a Martin propane heater is offset over time by savings on energy bills. Adjustable heat settings and the built-in thermostat mean you use only the fuel needed to maintain your target temperature.

Propane is generally cheaper to run than electric resistance heat, and the heater itself needs minimal maintenance. The die-cast aluminum grill holds up over time, and piezo ignition keeps operation simple and reliable.

In homes, a wall heater provides cozy, consistent warmth even through the coldest stretches. For remote cabins, propane's independence from grid electricity makes it a genuinely practical choice.

Garages and workshops benefit from a robust, reliable heat source too. With a heavy-duty grill and CSA certification for the US and Canada, Martin heaters are built to handle a range of environments, with built-in overheat protection keeping operation safe across all of them.

An oxygen depletion sensor monitors room oxygen levels and triggers an automatic shutoff if they drop too low, adding a layer of protection even in smaller, enclosed spaces.

The built-in thermostat and the overheat protection are two separate features working together: the thermostat holds your set room temperature by adjusting the flame, while a dedicated overheat safeguard independently shuts the unit down if internal temperature runs higher than it should, regardless of the thermostat setting.

Certification matters when it comes to safety. Martin propane heaters are CSA-certified for use in both the US and Canada, meaning they've passed rigorous, standardized testing for residential use.

That certification is a meaningful signal: it means the heater has been independently tested against recognized safety standards, not just the manufacturer's own claims.

Direct-vent heaters expel combustion gases directly outside, so no harmful fumes ever enter the living space. Drawing combustion air from outside rather than the room also means indoor air quality stays unaffected.

That sealed design doesn't come at the cost of comfort: Martin's direct-vent heaters still deliver consistent, adjustable heat with efficient dispersion throughout the room, with minimal fuel wasted in the process.

• Martin wall heater unit (direct-vent gas heater)
• Installation kit (included with the heater)
• Drill and appropriate bits
• Screwdrivers (flathead and Phillips)
• Level
• Measuring tape
• Gas fitter tools (for a licensed professional connecting to an existing gas line)
• Safety gear (gloves, goggles)
• Sealant

Step 1: Choose the Location

Select a spot on an exterior wall where the heater can disperse heat effectively. Confirm the wall thickness can accommodate the direct-vent assembly, and check for any obstructions on the exterior side where the vent terminal will sit.

Step 2: Prepare the Wall

Mark the vent pipe position using the installation manual's template, drill a pilot hole, then cut the opening. Make sure it aligns precisely with the heater's vent specifications.

Step 3: Mount the Heater

Position the heater and use a level to confirm it's straight. Mark the mounting points, drill holes for the anchors, and secure the heater with the screws from the installation kit.

Step 4: Install the Vent Pipe

Assemble the vent pipe per the manual and feed it through the wall, confirming it extends properly to the outside. Seal around it on both the interior and exterior sides to prevent drafts and keep the system sealed.

Step 5: Connect the Gas Line

If you're connecting to an existing propane or natural gas line, this step calls for precision and should be handled by a licensed gas fitter to ensure a secure, leak-free connection. Once connected, the piezo ignition makes lighting the unit straightforward.

Step 6: Final Adjustments and Testing

Once installed, check the thermostat and confirm it's reading room temperature accurately. Adjust the flame and heat settings to your preference. On visor models, the glass-ceramic window lets you watch the flame adjust as it works.
