How alternatives differ from ECCOTEMP
Ranein 8.5 GPM Outdoor Natural Gas Water Heater
The Ranein 8.5 GPM unit offers a higher flow capacity than the 7.0 GPM Eccotemp, making it suitable for larger households with simultaneous water demands. It shares the outdoor natural gas installation requirement, so venting needs remain minimal for both. However, the Ranein model is slightly narrower, measuring 15.1 inches wide compared to the Eccotemp’s 17.1 inches. This compact footprint may benefit tight outdoor spaces. The Ranein is ideal if you need extra gallons per minute without sacrificing outdoor convenience. You get more hot water volume, but the trade-off is a different brand ecosystem and potentially different warranty terms. Check your specific flow requirements before choosing this higher-capacity option.
APUS 190,000 BTU Outdoor Natural Gas Water Heater
The APUS 190,000 BTU heater provides app control, a feature the standard Eccotemp model does not explicitly list in its included accessories. Both units are designed for outdoor natural gas use, ensuring similar installation flexibility. The APUS is significantly narrower at 6.54 inches wide, offering a much slimmer profile than the Eccotemp’s 17.1-inch width. This makes it a better fit for confined wall spaces. The APUS targets buyers who want digital management of their water heating. You gain smart connectivity but may sacrifice the included remote control and specific sensor technology found in the Eccotemp. Choose this if app integration is a priority over physical controls.
Rinnai 7.6 GPM Outdoor Natural Gas Water Heater
The Rinnai RE199eN delivers a higher flow rate of 7.6 GPM compared to the 7.0 GPM Eccotemp, providing more consistent hot water for larger homes. Both are outdoor natural gas units, so installation requirements are similar. The Rinnai is slightly narrower at 14.1 inches wide but taller at 24.6 inches high, contrasting with the Eccotemp’s 26.2-inch length. It weighs more at 53.3 pounds, indicating a more robust build. This model suits buyers prioritizing long-term durability and brand reputation. You get increased flow and a premium build, but the trade-off is a higher initial investment and a different physical footprint. It is ideal for those seeking maximum reliability in an outdoor setting.
Westinghouse 8.1 GPM Outdoor Natural Gas Heater
The Westinghouse 8.1 GPM heater offers a higher flow rate than the 7.0 GPM Eccotemp, ensuring better performance for whole-home applications. Both units are designed for outdoor natural gas installation, maintaining similar venting simplicity. The Westinghouse is wider at 17.1 inches, matching the Eccotemp’s width, but it is taller at 26.8 inches. It weighs less at 42 pounds, making it slightly easier to handle during installation. This model is best for users who prioritize stable temperature control and higher flow. You gain more gallons per minute but lose the included remote control and specific sensor technology of the Eccotemp. Choose this if flow stability is your primary concern.
Rheem RTG 9.5 GPM Outdoor Natural Gas Tankless Heater
The Rheem RTG 9.5 GPM provides the highest flow rate in this comparison, significantly outperforming the 7.0 GPM Eccotemp. Both are outdoor natural gas units, but the Rheem includes WiFi connectivity, a feature not listed for the Eccotemp. The Rheem is narrower at 13.5 inches wide and shorter at 20.8 inches high, offering a more compact vertical profile. It weighs less at 39.3 pounds, facilitating easier mounting. This unit is ideal for large households needing maximum hot water volume. You get superior flow and smart features, but the trade-off is a different brand experience and potentially different warranty coverage. It is the top choice for high-demand outdoor setups.
Rinnai 7.5 GPM Outdoor Natural Gas Tankless Water Heater
The Rinnai RUS75eN offers a 7.5 GPM flow rate, slightly higher than the 7.0 GPM Eccotemp. Both are outdoor natural gas heaters, requiring similar installation conditions. The Rinnai is narrower at 14.5 inches wide but significantly taller at 35 inches high, creating a distinct vertical footprint compared to the Eccotemp. It lacks listed weight data, but its build suggests durability. This model suits buyers who prioritize flow and brand reliability over compact size. You gain a bit more flow and a premium brand, but you lose the included remote control and specific sensor technology of the Eccotemp. Choose this if you have the vertical space and want a trusted name in tankless heating.
