Buying Guide: How to Choose the Best Tankless Water Heater

If you’re looking to buy a tankless water heater, there are some things you need to consider before hitting the store. It’s important that you do your research before dropping hundreds or even thousands of dollars on your next hot water system.

Here are many things to consider when choosing your next tankless water heater:

  • Power
  • Warranty
  • Energy
  • Temperature Capacity
  • Efficiency
  • Multiple Outlets
  • Access Panels

Power

Ensure that it’s gas-powered. While there are some electric tankless water heaters on the market, they tend to be less energy efficient than their gas counterparts (the majority of tankless systems available today use natural gas). If you have a well, you’ll save even more money with a gas system since you won’t have to pay for an electric line installation to your home.

Warranty

Find out what kind of warranty is available. The best tankless water heaters have at least a 10-year warranty, but many manufacturers offer longer warranties than that. Additionally, if you’re buying the system through an authorized dealer, you may qualify for free installation and any other special offers or coupons that they may be running.

Energy

Compare the energy factor of different tankless water heaters to find the most efficient system for your home. The higher the EF, the more you can expect your tankless unit to save you on fuel costs over time. Most systems should have an EF of at least .90, with some even reaching as high as .95 or higher.

Temperature Capacity

Look for a tankless system that has a temperature capacity of at least 120 degrees Fahrenheit, but preferably 140 degrees F or above. The hotter your water, the less often you’ll have to run the shower to get the temperature you want. You may even be able to install multiple tankless systems in one home with certain brands.

Efficiency

Make sure that the tankless water heater you purchase is Energy Star Certified, which means that it meets or exceeds federal guidelines for energy efficiency. Remember, buying a tankless water heater might cost more upfront than a traditional storage model, but it will pay for itself within five years based on your monthly energy savings.

Multiple Outlets

For families with more than one bathroom, look for a tankless water heater that has multiple outlets. These typically come in packs of two or three and will be installed next to each showerhead.

Access Panels

Lastly, you’ll want to make sure that your new tankless unit comes with access panels on the outside (for maintenance purposes) and is energy efficient enough to qualify for a tax credit.

FAQs

  1. Do mini tankless water heaters work?

That answer is too simple though because the “mini” part of the name causes some people to ask if it’s not an oxymoron since a tankless water heater certainly does not look mini by any stretch of the imagination. The more accurate description for this type of water heater is “condensing”.

  1. What brand of tankless water heater is most reliable?

– All brands seem to be unreliable to some degree but you should go for the suitable one according to your necessity.

  1. What is bad about tankless water heaters?

– Tankless units heat on demand and do not hold water at a hot temperature. They typically have a lower efficiency than tank units, provide less hot water for the household than traditional tank-style units, and typically cost more to install.
