A higher wattage translates to a faster heating rate, as more energy is being forced into the water per second. Decoding the Specifications: Wattage and Tank Size To predict how long your unit will take, you must first look at the label.
These times assume the unit is starting with a completely empty tank; if there is residual warmth in the tank, the duration will be significantly shorter. The math boils down to the energy required to raise the temperature of a specific mass of water, which is why recovery rates are usually listed in gallons per hour.
