Mr. Heater vs. Martin Heaters: Which Is Better?
Key Takeaways
- Wall heaters make sense for supplemental heat, new spaces, or off-grid buildings where running ductwork isn't practical
- Martin's piezo ignition and self-powered millivolt thermostat have no battery dependency at all, while some larger Mr. Heater wall models rely on a battery for ignition
- Mr. Heater wins on upfront price, often under $200 for a 20,000 BTU unit, but burns through fuel quickly and has a shorter typical service life
- Martin costs more upfront but runs more efficiently, needs less maintenance, and commonly lasts 20-plus years

If you want a reliable heat source but don't want to spend fall splitting wood, a wall heater is worth a look. In theory it's a great option: lower installation cost than ducted systems, no floor space lost, and dependable heat. But electric wall heaters go dark during a power outage. So what's the better fuel source, which brand holds up, and is a wall heater the right call at all? Let's compare Mr. Heater against the Martin Propane Heater and see which fits your situation.
Why Choose a Wall Heater?
Wall heaters are a solid way to supplement your existing heat, warm a new or additional space, or heat an off-grid building entirely. Both Mr. Heater's smaller vent-free units and Martin's direct-vent line use piezo ignition, a manual, fully mechanical spark with no battery required. That means you're never dependent on grid power to start the unit. Some of Mr. Heater's larger wall models do use a battery-powered electronic ignition instead, which is worth checking before you buy if outage reliability matters to you, since a dead battery there could prevent ignition exactly when you need heat most.
For Mr. Heater, you'll need propane or natural gas depending on the model. Martin runs on propane or natural gas as well. Both connect directly to a tank or line outside your home. Here's how the two compare in practice.
Mr. Heater Performance
Mr. Heater's gas wall heaters are popular for being affordable, accessible, and easy to set up. A 20,000 BTU wall heater can run under $200, which is hard to beat on price. The trade-off is fuel consumption and longevity: these are thirstier heaters that don't last as long as a direct-vent unit under heavy use.
On average, a 1lb propane tank lasts around 4.5 hours of heating, depending on model and setting, while a 20lb tank lasts roughly 96 hours (about 4 days). During a cold winter stretch running the heater regularly, that means frequent refueling.
Given the lower price point, don't expect one of these to last indefinitely. Used as a regular winter heating source with proper maintenance, a typical unit holds up for around 5 years.
Martin Heater Performance
Martin's direct-vent propane heaters are some of the better options on the market. They connect directly to your propane tank, include solid built-in safety features (sealed combustion, overheat protection, an oxygen depletion sensor), and run efficiently. Propane itself is generally cheaper to run than electric resistance heat and produces fewer emissions than coal or heating oil, though the comparison to grid electricity varies by region depending on how your local power is generated.
Martin heaters cost more upfront, but they commonly last 20-plus years with heavy use and need very little ongoing maintenance. You generally get what you pay for. Read our full Martin heater review for more detail.
Frequently Asked Questions
Do Mr. Heater and Martin wall heaters need electricity to run?
Martin's direct-vent models use piezo ignition and a self-powered millivolt thermostat, so they don't need household electricity or a battery at all. Mr. Heater's smaller vent-free units also use piezo, but some larger wall models use a battery-powered electronic ignition instead, which is worth confirming if power outages are a real concern for you.
How long does a propane tank last on a Mr. Heater wall unit?
A 1lb tank runs roughly 4.5 hours depending on model and setting, while a 20lb tank lasts around 96 hours. During heavy winter use, expect to refuel often.
Which lasts longer, Mr. Heater or Martin?
A Mr. Heater wall unit used regularly through winter typically holds up for around 5 years with proper maintenance. Martin's direct-vent heaters commonly last 20-plus years, which factors heavily into the long-term cost comparison despite Martin's higher upfront price.
Choose the Wall Heater That Fits Your Needs
Martin heaters are the stronger choice for long-term savings, durability, and reliability. They cost more to purchase, but installing and maintaining them pays off over the life of the unit. If you need a budget-friendly option for occasional or short-term use, Mr. Heater's lower upfront cost is appealing, just plan for more frequent refueling and a shorter service life.
