Buying a Hot Water Heater is Complicated

buying a hot water heater can get complicated Buying a hot water heater should be easy, right? But it’s not, buying a hot water heater can get really complicated.

So the first question is when should you buy a new hot water heater? That depends on how old your current hot water heater is and hopefully you know the answer. Hot water heaters generally last 8 to 12 years, with less expensive ones failing faster than water heaters made with higher quality parts. For example, more expensive water heaters have two anode rods that rust out and protect your tank (learn more about anode rods). Water heaters also last longer when you drain and flush the tank every year to remove the sediment, and replace the anode rods as needed.

Factors to Consider When Buying a Hot Water Heater

If you are getting close to needing a new hot water heater, then consider replacing yours this month because … there’s a federal tax credit for installing energy efficient hot water heaters but it ends December 31, 2013. So here are the decisions you need to make when buying a new hot water heater, along with a fun infographic from the Department of Energy (DOE).

  • What type of fuel do you use for your hot water heater? Solar (tax credit until 2016) and heat pumps are much more energy efficient. If you have an electric water heater, do you have an opportunity to switch to gas?
  • Do you have enough hot water today? The capacity of your hot water heater affects how long a shower you can take (or 2 at once) and heating bills. You might benefit from increasing (or decreasing) your hot water capacity and this becomes more critical when switching to a tankless hot water heater.

Here’s the list provided to Oregon homeowners and don’t get confused by their “state tax credit” which is in addition to the federal tax credit.
  • What other factors should you consider when buying a hot water heater? A hot water tank takes up a lot of space, so switching to a tankless water heater could free up space.
