BTU (British Thermal Unit), a simple standard to measure how quickly and efficiently hot water is heated, refers to the amount of energy used to raise the temperature of one pound of water by one degree Fahrenheit. Since the water heater will have more power, it'll be able to heat the water more efficiently. In most cases, it's best to buy the heater with the higher rating.
