As a professional in the field of home appliances, particularly with expertise in water heating systems, I can provide you with a detailed explanation regarding the recovery rate of a hot water heater.

The recovery rate is a critical performance metric for water heaters. It refers to the rate at which the water heater can **raise the temperature of the inlet water by 90 degrees Fahrenheit**. This measure is particularly important because it indicates how quickly a water heater can replenish hot water after it has been used. The recovery rate is typically expressed in gallons per hour.

Understanding the recovery rate is essential when selecting a water heater for your home or business. It helps you determine whether the unit will be able to meet your hot water demands, especially if you have multiple fixtures running simultaneously or if you have a large family.

Typical 50-gallon water heaters have recovery rates in the range of 40 gallons per hour. This means that they can heat 40 gallons of water to the desired temperature in an hour. However, this is just a starting point. The actual recovery rate can vary based on several factors, including the efficiency of the water heater, the temperature difference between the inlet water and the desired outlet temperature, and the capacity of the tank.

For households with higher hot water demands, there are heavy-duty models available that boast recovery rates as high as 50 to 60 gallons per hour. These models are designed to provide a continuous supply of hot water, even during periods of high demand. They are particularly useful for larger homes, commercial applications, or situations where multiple showers or appliances are being used at the same time.

When considering a water heater, it's also important to look at its first-hour rating (FHR). The FHR is the total amount of hot water a water heater can provide during the first hour of operation, based on a specific recovery rate. This rating takes into account the size of the tank and the recovery rate, giving you a more comprehensive understanding of the water heater's performance.

In summary, a good recovery rate for a hot water heater depends on your specific needs and usage patterns. For most households, a recovery rate of 40 gallons per hour is sufficient. However, for those with higher demands, looking into models with recovery rates of 50 to 60 gallons per hour may be necessary. Always consider the FHR and the overall efficiency of the unit to ensure it meets your requirements.
