POINTS TO CONSIDER:
1. Are you shopping for a whole-house system or several point-of-use units? Keep in mind that point-of-use units can nicely supplement a whole-house system.
2. Size matters: Carefully measure the space where you’ll be installing your water heater to ensure that the unit will fit.
3. Efficiency: Fuel and heater type are important, but so is the capacity of the heater you choose. Be sure to select a unit that matches your family’s needs.
