Condensing water heaters have higher first-hour ratings and recovery rates than non-condensing models. The pump removes heat from the air outside the home and transfers it inside as a means of heating. A gas or electric water heater’s energy factor (EF) is a measurement that compares the amount of hot water the heater produces per day to the amount of fuel it consumes. Instead, tankless water heaters are rated for size by their “flow rate,” measured in gallons per minute (GPM). So, if you’re more concerned with having enough hot water and not running out, a gas water heater is best. Because the electricity is used to move heat from one place to another instead of converting that electricity directly into heat (as with electric-resistance water heating), the energy yield per unit of electricity input is much greater.
