Things to consider when choosing a tankless water heater

  • Flow rate: This is the amount of water that the heater can deliver per minute. A higher flow rate is necessary for larger homes or homes with multiple bathrooms.
  • Fuel type: Tankless water heaters can be powered by electricity, natural gas, or propane. Choose the fuel type that is most readily available and affordable in your area.
  • Energy efficiency: Tankless water heaters can be very energy-efficient, but it is important to choose a model with a high Energy Star rating.
  • Warranty: Choose a heater with a long warranty so that you are protected against any defects.
