Martin MDV12P Direct Vent Propane Heater (11,000 BTU)
The Gold Standard for Cabin and Tiny House Heating
The Martin MDV12P is our #1 recommendation for homeowners and off-grid enthusiasts who need a "set-it-and-forget-it" heating solution. Delivering 11,000 BTUs of consistent, dry heat, this direct-vent unit is specifically engineered for spaces up to 350 sq. ft.—making it the perfect fit for primary bedrooms, well-insulated cabins, or workshops.
Why the MDV12P Beats the Competition
While other heaters rely on noisy fans or complicated electrical hookups, the Martin MDV12P is a completely powerless system. Using a precision Piezo ignition and a built-in thermostatic dial, it provides silent, radiant heat that keeps your pipes from freezing and your space cozy, even during a total power outage.
- No Electricity Needed: Perfect for off-grid living or as a fail-safe backup during winter storms.
- Direct-Vent Technology: All combustion air is drawn from outside and exhausted back out, meaning zero indoor moisture buildup and 100% safety from CO gasses.
- Die-Cast Aluminum Grill: The heavy-duty front grill is designed for maximum heat transfer while staying cool enough at the back to protect your walls from scorching or discoloration.
- Precision Comfort: Unlike "on/off" heaters, the Martin thermostat modulates the flame. As your room reaches the set temperature, the flame lowers automatically to save fuel and maintain a steady environment.

Frequently Asked Questions:
Can I install the Martin MDV12P in a bedroom?
Yes. Because it is a "Direct Vent" unit, it is sealed from the room’s air and is CSA certified for use in bedrooms and bathrooms where "vent-free" heaters are often prohibited.
Does it come with the vent kit?
Yes, the MDV12P includes a complete telescopic vent kit that fits standard exterior walls. No extra chimney or venting parts are required.
Can I run this on a 20lb BBQ tank?
Yes, though for full-time winter use, we recommend a 100lb tank or an auto-changeover regulator to ensure you don't run out of fuel during a cold snap.
Do they come with a Warranty?
Martin heaters (manufactured by Bismar) come with a two-tiered warranty that is very competitive for the industry, particularly regarding the core heating element. 1-Year Limited Warranty: Covers all functional parts and components against defects in materials and workmanship. Lifetime Warranty: Covers the combustion chamber (the most critical part of the heater)
