ProCom ML100TPA-B Ventless Propane Infrared
This compact infrared heater runs on liquid propane and produces up to 10,000 BTU, suitable for small to medium rooms. It includes a thermostat control with High/Medium/Low settings for adjustable output. The unit is designed to mount on a wall or stand on included base feet, offering flexible placement. The white finish and slim profile aim to blend with residential spaces while providing direct radiant heat rather than heating air. Safety features common to ventless propane infrared heaters typically include oxygen depletion sensors and tip-over protection—confirm model-specific certifications and safety details before installation.
ProCom MN100TBA-B Ventless Natural Gas Blue Flame
The ProCom MN100TBA-B is a blue flame ventless heater running on natural gas with a 10,000 BTU output, designed to heat spaces up to about 500 sq. ft. Like the infrared model, it has a built-in thermostat and multiple heat settings for zoning. Blue flame heaters warm air directly and can be efficient for whole-room heating. The unit ships with wall mounting hardware and base feet for floor placement. Confirm local codes for ventless natural gas appliance use and ensure adequate room ventilation where required by regulations.

The L.B. White Tradesman 170N is a high-output forced air natural gas heater made for industrial and construction settings. Rated for 125,000–170,000 BTU/hr, it uses direct-fired technology aimed at large, open spaces like warehouses or job sites. Notable features listed include electronic spark ignition, diagnostic lights, and a durable tri-shield coating for abrasion and corrosion resistance. This unit is intended for outdoor or well-ventilated areas and is not a household indoor ventless heater. Verify jobsite ventilation and fuel connections before deployment.
MIZUDO Natural Gas Tankless Water Heater
The MIZUDO tankless unit is a natural gas on-demand water heater delivering up to 4.3 GPM and 100,000 BTU. It heats water within seconds and is designed for indoor installation feeding 2–3 low-flow fixtures. Features include an oxygen-free copper heat exchanger for faster heating and UL/CSA certification for third-party safety compliance. The tankless design reduces standby energy use because the burner activates only during hot water demand. Confirm proper venting, gas line sizing, and local code compliance when installing an indoor tankless gas appliance.
Bradford White Natural Gas Control Valve
This Bradford White Icon 2.0 replacement gas control valve is a 1″ millivolt-powered unit intended as an OEM replacement for residential water heaters. It features advanced temperature control for accurate water setpoints, pilot-on indication, and simplified lighting instructions. The millivolt power source means it requires no external electrical supply, useful for installations where electricity is not available. The product notes universal replacement compatibility and available service kits for prior ICON versions—verify model compatibility with your water heater before purchasing replacement parts.
Buying Guide
When selecting a white gas heater or related gas heating equipment, consider the following key factors to match the product to your needs.

Fuel Type And Availability
Identify whether the space uses propane (LP) or natural gas. Propane units like the ProCom ML100TPA-B require liquid propane supply, while the ProCom MN100TBA-B and many residential units operate on natural gas. Industrial models and tankless systems have specific gas line size and pressure requirements.
Intended Use And Coverage Area
Match heater BTU output to the area. Small ventless space heaters rated around 10,000 BTU are for rooms up to several hundred square feet. Large forced-air units deliver tens to hundreds of thousands of BTU for job sites or warehouses. Tankless water heaters specify GPM and fixture capacity rather than square footage.
Ventless Vs. Vented
Ventless heaters (blue flame or infrared) release combustion products directly into the room and may require oxygen depletion sensors and adherence to local codes. Vented or direct-vent appliances exhaust combustion gases outdoors and are typically preferred for indoor installations where permitted. Confirm local regulations and ventilation needs.
Safety Features And Certifications
Look for third-party certifications (UL, CSA) and safety features like oxygen depletion sensors (ODS), tip-over shutoff, overheat protection, and pilot safety systems. For water heaters and replacement parts, ensure OEM compatibility and certification to reduce installation risk.
Installation Requirements
Check gas line sizing, venting, clearance to combustibles, and electrical needs. Millivolt-powered water heater controls can operate without external power; other systems may need 120V connections or battery ignition. Professional installation is often required for gas appliances to meet code.
Efficiency And Operating Costs
For space heaters, efficiency depends on heating method—radiant infrared may feel warmer at lower air temperatures, while blue flame units heat room air. Tankless water heaters save standby energy by heating on demand but require adequate flow and BTU capacity.
Durability And Intended Environment
Industrial heaters like the L.B. White Tradesman are built for rugged environments with heavy-duty construction and diagnostic systems. Residential space heaters prioritize aesthetics, compactness, and quieter operation. Choose materials and finishes suited to usage conditions.
Replacement Parts And Serviceability
For water heaters and controls, confirm availability of replacement valves, pilot assemblies, and service kits. Products that list OEM replacement numbers and compatibility simplify repairs and maintenance.
Comparison Perspectives
- Small Indoor Rooms: A 10,000 BTU ventless heater (infrared or blue flame) offers compact, targeted heating with thermostat control.
- Whole-Home Water Heating: A tankless natural gas unit is appropriate if peak GPM and burner capacity meet household demand and venting is available.
- Large Open Spaces: Choose high-BTU forced-air industrial heaters designed for outdoor or ventilated areas; they are not suitable for standard indoor living spaces.
- Repair & Maintenance: For existing water heaters, OEM control valves and pilot assemblies ensure compatibility and simplify servicing.
Before purchasing, verify product certifications, local code compliance, and whether professional installation is required. Match the heater type to the space, fuel availability, and safety priorities to select the most appropriate white gas heating solution.
