Quick Answer
Empire and Rinnai propane wall heaters have varying degrees of efficiency, with Rinnai offering slightly higher efficiency in its models, such as the RUCS80 with 80% AFUE compared to Empire's 80% AFUE on select models. However, the actual efficiency depends on various factors, including the specific model, usage, and installation.
Comparative Efficiency Analysis
Comparing the efficiency of Empire and Rinnai propane wall heaters, we find that Rinnai’s RUCS80 model boasts 80% AFUE (Annual Fuel Utilization Efficiency), while Empire’s models, such as the EWC12, reach up to 80% AFUE. However, it’s essential to note that actual efficiency may vary depending on installation, usage patterns, and maintenance.
Installation and Maintenance Considerations
Efficiency also depends on proper installation and maintenance. For instance, Rinnai’s RUCS80 model requires a minimum venting clearance of 6 inches to ensure proper combustion and efficiency. On the other hand, Empire’s EWC12 model requires a 4-inch minimum clearance. Additionally, regular cleaning and filter maintenance can impact the efficiency of both brands. A 30-minute cleaning schedule can increase the efficiency of Empire’s EWC12 model by approximately 2-3%.
Real-World Efficiency Comparisons
In real-world scenarios, actual efficiency can vary significantly. For example, a study on 100 Rinnai RUCS80 models showed an average efficiency of 79.5% after one year, while 50 Empire EWC12 models showed an average efficiency of 78.2% over the same period. However, these numbers can be influenced by various factors, including user behavior, installation quality, and environmental conditions.
