10 Best Propane Shop Heaters 2026 in the United States

The Rinnai EX08DTP is a propane-powered indoor wall furnace designed to efficiently heat spaces up to 1600 square feet with an 8,000 BTU output. Its advanced modulating technology allows it to adjust heating in small increments, helping maintain a steady, comfortable temperature between 60 and 80°F. This feature makes it energy efficient, which can save on fuel costs over time. The heater uses a reliable electronic spark ignition, eliminating the need for matches or pilot lights, and it includes a variable speed inducer motor that quietly distributes heat using forced air.

Safety is a strong point here: the unit has a cool-to-the-touch exterior, child lock, and self-diagnostic systems that automatically shut down the heater if any issues like failed ignition arise. This provides peace of mind for indoor use, especially in homes with children. However, the heater is designed for wall mounting and weighs 53 pounds, so it’s not portable and requires professional installation, which might add to initial setup costs. While it’s great for bedrooms or similar sized rooms, it’s not intended for larger or outdoor areas.

This Rinnai model is well suited for someone looking for a quiet, energy-saving propane heater for indoor spaces that is safe and easy to control via its electronic thermostat and timer settings. Buyers should be prepared for the wall installation process and consider the service support needed.

The Rinnai EX11CTP is a propane-powered, wall-mounted indoor heater designed for spaces like bedrooms, home offices, or small commercial areas. It offers a solid heat output of 11,000 BTUs, which can comfortably warm an area up to around 3,200 square feet using convection heating. The direct vent design improves indoor air quality by safely venting combustion gases outside, making it safer for home use compared to unvented heaters.

It features an electronic spark ignition and a precise electronic thermostat adjustable between 60°F and 80°F, allowing for consistent temperature control. The heater also includes useful smart features like a timer, a child lock for safety, and self-diagnostic electronics that help maintain reliable operation by shutting down or restarting if issues occur.

At 57 pounds and with wall-mount installation, it strikes a balance between portability and a permanent heating solution, suitable for homeowners who want a fixed but efficient propane heater. Although it is designed strictly for indoor use and requires proper venting, making installation more complex than portable models, it remains a dependable choice for those needing steady, efficient propane wall heating with safety and smart control features. Note that this model has been discontinued and replaced with a newer version, so support or parts may be limited.

The Mr. Heater Propane Unit Heater MHU80LP delivers a powerful 80,000 BTU per hour, making it well-suited for heating spaces up to 1000 square feet. With forced air as its heating method, it ensures a consistent and effective distribution of warmth, which is ideal for larger shop areas. The heater's spark ignition with a self-diagnostic control module adds reliability and ease of use, reducing troubleshooting time in case of issues.

Furthermore, the included angle brackets simplify the ceiling mount installation, allowing for flexible placement within the shop environment. However, the unit's 90.1-pound weight may pose challenges for portability, making it less convenient to move once installed. While the 4-inch flue size and 1/2-inch gas connection are standard, they need proper setup, which might require professional installation.

On a positive note, the product comes with a generous warranty—three years on parts and burners, and ten years on the heat exchanger—indicating the manufacturer's confidence in its durability. This heater is a strong candidate for those needing a robust and efficient heating solution for larger spaces, provided they can manage the installation.
