The best natural gas heater depends on your room size, preferred heat style, and whether you need thermostat control or fuel flexibility. The Mr. Heater 30,000 BTU model is suited to larger areas, while the ProCom 10,000 BTU models are better for spaces up to 500 square feet. Prices vary by model and seller, so compare features and installation requirements rather than relying on a single price estimate.

Mr. Heater 30,000 BTU Blue Flame
This natural gas heater produces 30,000 BTU per hour and is listed to heat areas up to 1,000 square feet. Its battery-operated electronic ignition is supplied with a battery, so the listed ignition feature does not depend on a household electrical outlet.
Best for: Buyers heating a larger space who want electronic ignition. It was selected for its higher output and stated coverage. Compare the room’s layout and insulation with the coverage claim before choosing a heater.
Consideration: The provided features do not list thermostat control or multiple heat settings. Choose another option if those controls are priorities.
ProCom 30,000 BTU Infrared Plaque Heater
This ventless infrared plaque model uses natural gas only, has a maximum output of 30,000 BTU, and is listed for spaces up to 1,200 square feet. It requires no electricity and uses push-button piezo ignition. Manual controls provide Low, Medium, and High settings. An oxygen depletion sensor is listed with automatic shutoff.
Best for: Buyers seeking a high-output natural gas heater with manual settings and no electrical requirement. Its listed coverage is the largest among these five options.
Consideration: It is natural-gas-only, so avoid it if you need a propane-capable model. Manual controls may also be less suitable for buyers who specifically want thermostat operation.
ProCom 10,000 BTU Infrared Plaque Heater
This compact infrared model uses natural gas and is listed to heat up to 500 square feet. It has thermostat control with High, Medium, and Low settings. The product information says it can be mounted on a wall using included hardware or placed on the floor with included base feet.
Best for: Buyers who want a smaller heater with thermostat control and flexible placement. It is a practical comparison choice for an office, bedroom, or living room within the stated coverage range.
Consideration: Its 10,000 BTU maximum output is lower than the 30,000 BTU options, so it may not suit a larger or harder-to-heat area.
ProCom 10,000 BTU Blue Flame Heater
This compact blue-flame heater uses natural gas, produces up to 10,000 BTU, and is listed for rooms up to 500 square feet. It includes thermostat control with High, Medium, and Low settings. The listed placement options include wall mounting with included hardware or floor placement using the included base feet.
Best for: Buyers looking for a small-space natural gas heater with thermostat control and blue-flame technology. It offers the same stated capacity and placement options as the ProCom infrared model, making heat style a key point of comparison.
Consideration: It is designed for smaller areas based on its listed capacity and coverage. Consider a higher-output model for larger rooms.
30,000 BTU Dual-Fuel Wall Heater
This vent-free wall heater is listed for natural gas or propane, with infrared heating, 30,000 BTU per hour, and coverage up to 1,000 square feet. It has electronic spark ignition and thermostatic control. The listed safety features include an oxygen depletion sensor and automatic shutoff; the product information also states CSA certification.
Best for: Buyers who want the option of natural gas or propane and prefer thermostat control. It was selected for its fuel flexibility compared with the natural-gas-only models.
Consideration: Confirm which fuel you will use and follow the product instructions for that fuel. Choose a natural-gas-only model if dual-fuel capability is unnecessary.
Buying Guide: How to Compare Natural Gas Heaters
What size heater should you choose?
Start with the manufacturer’s stated coverage area, then consider room layout, ceiling height, insulation, and drafts. The products here range from 10,000 BTU models listed for up to 500 square feet to 30,000 BTU models listed for 1,000 or 1,200 square feet. Coverage figures are product claims, not a guarantee of equal heating in every home.
Do you need thermostat control?
Thermostat control is listed on both 10,000 BTU ProCom models and the dual-fuel wall heater. The 30,000 BTU ProCom infrared plaque heater instead has manual Low, Medium, and High settings. Choose thermostat operation if adjusting output automatically is important; choose manual controls if distinct fixed settings meet your needs.
How do heat type and fuel affect the choice?
Infrared plaque and blue-flame models are different heat styles. Compare the product type that fits your preference, but do not assume identical performance beyond the listed specifications. Four models are described as natural-gas-only; the wall heater is listed for natural gas or propane.
What should you check before buying?
Confirm fuel supply, ignition method, placement options, and the installation instructions. Vent-free heaters may be restricted by local rules or by the conditions of a particular room. Check local requirements and the manufacturer’s safety guidance before purchase and operation. Prices can change by seller and model; compare current listings for the exact product configuration.
