Tradesman CP170NU Portable Propane LP Heater (Related Model)
The Tradesman CP170NU represents a closely related line in the Tradesman family, offering adjustable heat output from 125,000 to 170,000 BTU per hour. While designed for propane, its construction emphasizes durability and reliable start-up with a thermostatic control approach. The unit retains Wisconsin manufacturing quality and a heavy-gauge combustion chamber, supporting tough conditions on job sites or industrial spaces that use propane as a fuel source. Operators should consider fuel type compatibility with existing infrastructure and any ventilation requirements related to propane combustion.
Considerations include fuel supply stability, potential odor or ventilation needs, and operational costs tied to propane usage. The CP170NU can serve as a practical comparison point for users weighing propane-compatible heat options against natural gas units, particularly when existing gas lines or safety standards influence fuel choice on a given site.
InoKraft MaXheat MH125 125,000 BTU Propane Heater
The InoKraft MaXheat MH125 offers 125,000 BTU per hour with a portable design suitable for garages, job sites, and large workshops. It includes a 10-foot hose and regulator for convenient setup.

Buying Guide: Key Purchase Considerations for Natural Gas Forced Air Heaters
- Fuel compatibility and infrastructure: Natural gas units rely on an existing gas line and proper venting. If your space lacks natural gas, propane or kerosene models may be viable alternatives, but you should assess long-term costs and availability.
- Heat output and space size: Match BTU ratings to the target area, taking into account ceiling height, insulation, and airflow. Oversized units waste energy, while undersized units fail to maintain comfortable temperatures.
- Ventilation and safety: Direct-fired units require proper venting and adherence to installation codes. For indoor use, ensure adequate combustion air, venting clearances, and regular maintenance to prevent safety hazards.
- Durability and build quality: Look for heavy-gauge components, corrosion-resistant finishes, and durable casings designed for rough environments like job sites and warehouses.
- Ignition and controls: Electronic ignition, thermostatic control, and diagnostic indicators simplify startup and ongoing troubleshooting, reducing downtime on critical sites.
- Portability vs. fixed installation: Portable units offer flexibility on multi-site projects, while fixed units provide consistent heat with centralized venting. Consider space constraints and installation ease.
- Maintenance and parts availability: Choose brands with accessible service networks, readily available replacement parts, and documented service intervals to maximize uptime.
- Operating costs: Compare fuel prices, efficiency, and maintenance needs. Natural gas generally offers stable, predictable costs, but availability varies by location.
- Environmental and odor considerations: Propane and kerosene options may produce odors or variable combustion byproducts; natural gas typically yields cleaner combustion with less handling of fuel storage.
In summary, natural gas heaters deliver substantial heat for large, open spaces when a reliable gas supply is available. Propane and kerosene units provide versatile options where natural gas lines are absent or impractical. When selecting a heater, prioritize space size, ventilation, and long-term operating costs, and ensure installation by qualified technicians to maintain safety and performance standards.
