How Each Alternative Compares

Camplux BW158B Portable Propane Heater

The Camplux BW158B matches the Ranein 6L at 1.58 GPM flow rate and propane fuel. It shares the outdoor installation location but weighs 13 pounds, which is heavier than the Ranein’s 9.92 pounds. Its dimensions are narrower at 5.1 inches wide, making it more compact for storage. You get similar low-pressure performance for camping showers.
