How to choose the right one
-
Check flow rate needs
Your flow rate determines how many fixtures can run at once. Single-point outdoor tasks, like camping or washing, only need 1.58 GPM. Models like the BE158 fit this need perfectly. Whole-house systems require higher outputs. The CE686LP delivers 7.6 GPM for multiple bathrooms. The CS528LPN2 offers 5.8 GPM for standard family use. Match the GPM to your maximum simultaneous water usage to avoid temperature drops.
-
Select installation location
Location dictates the unit type you need. Outdoor models like the BS318 are built for camping, RVs, and cabins. They prioritize portability and low-pressure start-up. Indoor units, such as the CE686LP, are designed for permanent home installation. They handle higher demands and require proper ventilation. Ensure your space matches the heater's intended environment. Outdoor units may not meet indoor safety codes, while indoor units lack weather resistance.
-
Verify BTU output
BTU rating indicates heating power. Higher BTUs warm water faster. The CE686LP provides 199,000 BTU for high-demand whole-house setups. The CS528LPN2 offers 150,000 BTU for reliable performance. Lower flow outdoor units do not list BTUs but rely on lower gas consumption. Ensure your propane supply can support the required BTU load. Insufficient gas pressure can reduce efficiency. Check your regulator and tank capacity to match the heater's power needs.
-
Assess startup pressure
Low startup pressure is critical for off-grid use. The BE158 operates at 3.6 PSI, allowing it to run without household electrical wiring. This makes it ideal for remote camping or cabins with limited power. Indoor units typically require standard electrical connections for ignition and controls. If you lack grid power, prioritize models with battery ignition and low PSI requirements. This ensures reliable hot water access in remote locations without complex setup.
-
Review safety features
Safety protections are essential for propane heaters. The BS318 includes overheat protection to prevent damage during operation. Indoor models like the CE528LP offer multiple safety mechanisms for continuous use. Look for freeze protection in units like the CS422BLPN2 for colder climates. Ensure your installation area has adequate ventilation for gas combustion. Proper venting prevents carbon monoxide buildup. Always follow manufacturer guidelines for safe operation and maintenance of your propane unit.
