Understanding Water Heater Recovery Rate
The recovery rate is the speed at which a water heater can heat the water back to the desired temperature after it has been used. It is generally measured in BTUs per hour. A higher recovery rate means your water heater will bring your water back up to the desired temperature more quickly.
Factors Affecting Recovery Rate
| Factor | Description | Impact on Recovery Rate |
|---|---|---|
| Water Heater Size | The size of your water heater determines the total amount of water to be heated. | Larger units take longer to recover. |
| Recovery Rate (BTU/hr) | The rate at which your water heater heats the water. | A higher BTU/hr rating results in a faster recovery rate. |
| Temperature Rise | The difference between the incoming water temperature and the desired water temperature. | A higher temperature rise requires more time and energy to recover. |
How to Estimate Recovery Time
The recovery time is calculated using the following formula:
Recovery Time (hours) = (Water Heater Capacity (gallons) × Temperature Rise (°F) × 8.34) / Recovery Rate (BTU/hour)
This formula calculates how many hours it will take for your water heater to raise the water to the desired temperature.
