Comparing Similar Outdoor Heaters
Rheem RTG 8.4 GPM Outdoor Natural Gas Tankless Heater
The Rheem RTG-84XLN-3 matches the Camplux at 8.4 GPM and uses natural gas for outdoor installation. It differs by offering WiFi connectivity for remote control, which the Camplux lacks. The Rheem unit is slightly wider at 13.5 inches compared to the Camplux’s 6.5 inches, making it bulkier for tight spaces. Both deliver similar heating power, but the Rheem adds digital precision and smart features. If you want app management and precise temperature settings without sacrificing flow rate, the Rheem is a strong choice. It suits buyers who prioritize modern control options over the Camplux’s simpler mechanical interface.
A. O. Smith 10 GPM Outdoor Condensing Tankless Heater
The A. O. Smith ATO-540H-N offers a higher flow rate of 10 GPM compared to the Camplux’s 8.4 GPM. It uses condensing technology, which can improve efficiency, while the Camplux is non-condensing. The A. O. Smith is significantly larger, measuring 17.8 inches wide and weighing 59 pounds, versus the Camplux’s compact 6.5-inch width and 39 pounds. It includes a remote control, adding convenience. This model suits households needing maximum hot water volume and efficiency. If you have the space and need higher output, the A. O. Smith is better. Otherwise, the Camplux remains more compact and easier to install in standard setups.
Ranein 8.5 GPM Outdoor Natural Gas Water Heater
The Ranein RHO19K-NG is marketed as an 8.5 GPM unit, slightly higher than the Camplux’s 8.4 GPM. However, its attributes list 5.0 GPM, creating a discrepancy. It is wider at 15.1 inches and heavier at 44 pounds compared to the Camplux. The Ranein includes anti-freeze features, similar to the Camplux. It is designed for low-elevation outdoor use. If you need a budget-friendly option with similar outdoor durability, this model fits. However, the conflicting flow rate specs make it less reliable than the Camplux. Choose the Camplux for clearer specifications and proven 8.4 GPM performance in natural gas setups.
APUS 190,000 BTU Outdoor Natural Gas Water Heater
The APUS AP-AWH-W26NG provides 190,000 BTU, slightly less than the Camplux’s 199,000 BTU. It shares the same compact dimensions and weight, making it a direct size alternative. The APUS includes app management for remote control, a feature the Camplux does not highlight. It is designed for whole-home outdoor hot water needs. If you want smart home integration and similar physical footprint, the APUS is a good option. The Camplux offers higher BTU output and more detailed safety certifications. Choose the APUS if app control is essential, or stick with the Camplux for higher heating power and verified safety standards.
Rinnai 7.6 GPM Outdoor Natural Gas Water Heater
The Rinnai REU-VE2737WD-US-N has a flow rate of 7.6 GPM, lower than the Camplux’s 8.4 GPM. It is wider at 14.1 inches and heavier at 53.3 pounds, making it less compact. The Rinnai uses non-condensing technology like the Camplux. It is known for strong warranty coverage and reliability. If you prioritize long-term durability and brand reputation over maximum flow rate, the Rinnai is suitable. The Camplux delivers more hot water and is easier to fit in tight spaces. Choose the Rinnai if you value warranty support and steady performance, accepting the lower GPM output for peace of mind.
MIZUDO 10.3 GPM Indoor Natural Gas Tankless Water Heater
The MIZUDO WCIU-HW199A1G-NG-M0 is designed for indoor installation, unlike the Camplux’s outdoor focus. It offers a higher flow rate of 10.3 GPM and 199,000 BTU. It includes app control for precise management. The MIZUDO is wider at 15.9 inches and heavier at 55.5 pounds. If you need indoor whole-house hot water with smart features, this model is appropriate.
