Types of Water Heaters

It’s a good idea to know the different types of water heaters available before you purchase one:

  • Conventional storage water heaters
    Offer a ready reservoir (storage tank) of hot water
  • Demand (tankless or instantaneous) water heaters
    Heat water directly without the use of a storage tank
  • Heat pump water heaters
    Move heat from one place to another instead of generating heat directly for providing hot water
  • Solar water heaters
    Use the sun’s heat to provide hot water
  • Tankless coil and indirect water heaters
    Use a home’s space heating system to heat water
Selection Criteria

When selecting the best type and model of water heater for your home, you also need to consider the following:

  • Fuel type, availability and cost
    The fuel type or energy source you use for water heating will not only affect the water heater’s annual operation costs but also its size and energy efficiency.
  • Size
    To provide your household with enough hot water and to maximize efficiency, you need a properly sized water heater.
  • Energy efficiency
    To maximize your energy and cost savings, you want to know how energy efficient a water heater is before you purchase it.
  • Costs
    Before you purchase a water heater, it’s also a good idea to estimate its annual operating costs and compare those costs with other less or more energy-efficient models.
