ProCom ML100TPA-B Ventless Propane Gas Infrared Space Heater
This compact ventless infrared heater is designed for indoor residential spaces and uses liquid propane. The manufacturer rates it at 10,000 BTU and suitable coverage up to about 500 sq. ft., with included wall mount and base feet for flexible placement.
Key features listed include thermostat control with High/Medium/Low settings, a slim modern profile, and mounting hardware. As a ventless appliance, it delivers direct radiant heat and does not require a chimney or venting system, but room ventilation and compliance with local codes are important considerations.
Considerations: check local codes for ventless propane appliance use, confirm propane supply and regulator compatibility, and evaluate required clearances for wall or floor placement.
ProCom MN100TBA-B Ventless Natural Gas Blue Flame Space Heater
This ventless blue flame heater operates on natural gas and offers up to 10,000 BTU output. It includes the same mounting options and thermostat control with multiple heat settings, intended for rooms up to approximately 500 sq. ft.
Features emphasize reliable thermostat control, a slim aesthetic for household spaces, and easy wall or floor installation using the included base feet and hardware. Blue flame operation produces convective and radiant heat, and may be preferable for continuous background warmth.
Considerations: natural gas connection requirements, local regulations for ventless appliances, and whether blue flame or infrared heating better suits the intended room layout and comfort goals.
L.B. White Tradesman 170N Portable Forced Air Heater
The L.B. White Tradesman 170N is a high-output portable forced-air heater intended for large, open work areas. Rated between 125,000–170,000 BTU/hr, it targets construction sites, garages, and warehouses where powerful temporary heating is required.
Listed features include direct-fired technology for high fuel efficiency, electronic spark ignition, diagnostic light for troubleshooting, and a durable tri-shield coated combustion chamber. This model is built for industrial durability and mobility rather than home installation.
Considerations: this is a commercial-grade unit requiring appropriate gas supply capacity, outdoor or well-ventilated use in many jurisdictions, and adherence to safety protocols for forced-air, direct-fired heaters.
MIZUDO Indoor Installation Natural Gas Tankless Water Heater
The MIZUDO tankless unit provides on-demand hot water with a maximum flow of 4.3 GPM and up to 100,000 BTU capacity, making it suitable for small homes or apartments serving 2–3 fixtures. It uses natural gas and is designed for indoor installation.
Key features include a copper heat exchanger for efficient heating, instant hot water delivery within seconds, and safety certifications (UL/CSA). The listing notes a 2-year whole unit and 5-year heat exchanger coverage from the manufacturer.
Considerations: sizing for simultaneous fixtures, proper venting and combustion air for indoor natural gas appliances, and professional installation to meet local code and gas line capacity requirements.
White‑Rodgers 37E73A-903 Gas Water Heater Thermostat Control
This listing is for a replacement thermostat control / Intelli‑Vent valve intended for natural gas water heaters. It’s specified as a replacement for model 37E73A-903 and designed for reliable temperature regulation and burner control.
The product targets homeowners or technicians performing repairs or replacements on compatible water heaters. Features typically include integrated pilot or ignition compatibility, temperature setpoint control, and safety shutoff functions common to OEM controls.
Considerations: ensure compatibility with your water heater model, follow manufacturer replacement instructions, and confirm local codes require a licensed technician for gas control replacements.
Buying Guide: How To Choose The Right White Gas Heater
Choosing the right white gas heater depends on intended use, fuel availability, room size, and local regulations. The guide below summarizes key considerations and comparison perspectives.
1. Fuel Type And Supply
Natural gas and propane are common fuel sources. Natural gaspropane
2. Ventless Versus Vented
Ventless heatersVented units
3. Heating Method: Infrared, Blue Flame, Forced Air
- Infrared
- Blue flame
- Forced-air
4. BTU Rating And Coverage
Match BTU output to space size and insulation quality. Small rooms typically require 5,000–12,000 BTU, while industrial spaces may need tens or hundreds of thousands of BTU. For hot water systems, flow rate (GPM) and BTU capacity determine simultaneous usage capability.
5. Controls, Thermostats, And Safety Features
Look for adjustable thermostats, multiple heat settings, electronic ignition or pilot systems, and built-in safety features such as oxygen depletion sensors (for ventless), flame failure protection, and thermal cutoffs.
6. Installation And Code Compliance
Installation complexity ranges from simple wall mounting to professional gas line and venting work. Always review local building codes for ventless device restrictions, required clearances, and licensing requirements for gas appliance installation.
7. Efficiency And Operating Costs
Efficiency depends on technology and usage patterns. Direct-fired forced-air units can be highly efficient for large open spaces, while ventless appliances often convert most fuel to usable heat in the room. Consider fuel price differences in your area.
8. Durability And Intended Use
Industrial models prioritize rugged construction and high output for job sites. Residential white gas heaters emphasize aesthetics, compact design, and quiet operation. Match the unit build and listed applications to your intended environment.
9. Replacement Parts And Serviceability
For water heaters and control valves, confirm part numbers and compatibility. Units from established manufacturers often offer replacement valves, pilots, and technical documents to simplify service and repairs.
10. Comparison Perspectives
- Residential comfort: consider ventless blue flame or infrared wall heaters for easy installation and concealed profiles.
- Small homes and apartments: tankless natural gas water heaters provide continuous hot water with compact footprints.
- Large open spaces or job sites: forced-air industrial heaters deliver high BTU output and robust durability.
- Repair and maintenance: OEM controls and pilot assemblies are key for reliable water heater operation.
