How to Choose Water Heater Size involves determining the appropriate capacity of a water heater to meet the hot water demands of a household. Factors influencing water heater size selection include the number of occupants, fixture count, and desired flow rate.
Selecting the right water heater size is crucial to ensure an adequate supply of hot water while avoiding energy waste and higher utility bills. Oversized water heaters can lead to standby heat loss and increased energy consumption, while undersized units may result in insufficient hot water availability.
