Factors in New Water Heater Selection

If you’ve noticed that your home’s water heating capacity is decreasing, resulting in cold showers and poor hot water flow around the house, it could be time to replace your hot water heater. This may also be the case if you’re looking to decrease your energy bills or have flooding or leaking issues with the current heater.

At My Buddy the Plumber in St. George, we can help you with everything involved in water heater replacement, from identifying the signs that it’s time to helping you choose the right heater option. There are a few water heater types out there, each with its own set of characteristics – here are some basics on what these styles are and some factors you should consider while making your choice.

Heater Type

Here are some of the primary choices when it comes to water heaters:

  • Conventional units: Also called storage tank units, these are the most common type of water heater in homes today. They contain a single insulated tank that heats and stores the water needed in the home, then distributes it as necessary to various fixtures.
  • Tankless water heater: A more modern option that does not store any water, removing the need for heating elements to keep water constantly hot. Instead, high-powered heating coils are used to heat water on-demand. They’ll not only bring you faster and more convenient hot water, they’ll also last longer and lower your energy costs in many cases.
  • Hybrid units: Also called heat pump water heaters, these are options that use heat from the air or ground around their area to heat water. They use electricity to draw heat from these areas, rather than creating it separately.
    • Efficiency

      When it comes to choosing which of the above options is right for you, efficiency will be one of your top considerations. This is true even when you’ve made your choice and are digging into specific manufacturers.

      The number to know here is Uniform Energy Factor, or UEF. The higher this number, the more energy efficient the unit is – these units will generally cost more up front, but will save you a lot of money on your utility bills over time. We can help you understand exactly how large this savings will be so you can calculate which is the right option.

      Size Considerations

      In addition, finding the proper size is very important. Your home only has a certain capacity for water heaters and related systems, and going too far above or below this threshold can lead to poor efficiency or poor water quality for those in the home.


      Finally, ask about warranties for any water heater manufacturer you are considering. These often offer you the ability to fix or replace elements at no cost. In many cases, it will make sense to purchase an extended warranty.
