A few things to keep in mind is that the warranty does not cover the repair costs, only the price associated with replacement.

All in all this is a solid tankless water heater that has brought satisfaction to many people who have purchased it.

Tankless Water Heater Buying Tips

Anytime someone researches a product, it’s good to have a few key areas to focus on. Not only will this help simplify the overwhelming buying process, but it will also help you key on the points that really matter to you. Here, we have compiled a list of the top points you should consider as you narrow down your top choices for a tankless water heater.

Quality

Quality is certainly an important feature for any product that you buy, but can be especially true when you are in the market for a tankless water heater. Keep in mind that the unit that you choose could mean the difference between a warm, relaxing shower or an unsatisfying one that goes cold midway through. Nobody wants to deal with that! When evaluating the quality of the unit consider the following:

  • What kind of materials are used? In tankless water heaters, brass and copper are often used because they are both durable Ensure that reviews indicate the material is long-lasting and there are no recorded issues of rusting or breaking after a few months.
  • What kind of attachments are required? Consider the quality of these items as well because if the unit is sturdy, but the attachments are not then that could likely mean issues in the future.

Safety

Safety is certainly a concern when it comes to tankless water heaters. While most are designed with safety in mind, you want to be sure about what is included under safety features. Some considerations:

  • Is there an automatic shut off? Not only can this help with safety, but also affordability.
  • Is there a digital thermometer that is easy and clear to read? This will ensure that you are heating the water properly and not scalding the individual while it’s in use.
  • Are instructions for installation clear? Be sure that you read over the instructions in their entirety. The reality is that many of these heaters outline safety restrictions during installation so that the unit is not at risk for catching fire or malfunctioning.

Capability

Many tankless water heaters have specific uses which should be understood prior to purchase. Knowing how to properly operate the unite will ensure that you are using it to its best ability and that you are getting what you paid for. Some considerations:

  • Is the unit identified as indoor or outdoor use? All units will indicate what their purpose is for. If they are intended as indoor use only, then you should recognize the installation and use restrictions. Keep in mind that some units are available for dual purpose.
  • How powerful is the water pressure? Often outdoor units operate on a considerably lower water pressure (although not always) make sure that you understand the pressure limitations and how that may impact your overall use of the heater.

Space

You definitely need to take into consideration the space that you have available for the unit as well as the size of the unit itself. Here are some things to keep in mind:

  • What kind of home do you live in? Some units are specifically designed for apartment use while others are better used in larger homes.
  • Do you have enough space to safely operate? Don’t ignore the restrictions when it comes to clearance required to operate the tankless water heater that you buy. Failure to do so could result in injury.
  • Can you store the unit if it is outdoor use only? Many of these units are pretty compact, but you should know where you will store the item when it’s not in use and ensure that it is stowed away safely.

Price

Price is something that many consumers rank as a priority. While it is certainly important, you need to be aware that you “get what you pay for”. This isn’t to say that you can’t find a quality tankless water heater for a good price, but you need to be weary of how price compares to quality. Keep this in mind:

  • What is your budget? Make sure that you have an established budget before you enter the marketplace. Offer a bit of a range so that you have some flexibility when it comes to comparison shopping.
  • What kind of features are you most interested in? Larger tankless water heaters may come at a hefty price, but you need to consider if you need a large tank or if a smaller tank will do the trick.
  • Do you want a multi-use unit? Sometimes, these units can cost more simply because they offer dual-use. Consider what you need for your situation and create a price point accordingly.

Warranty

All consumers should look up the warranty for any product that they have, but a tankless water is especially important if you consider how much you will likely use it in your everyday life. Here are some things to check out in the warranty:

  • How long is the warranty? Some warranties are only a year-long while others are at least a decade. The peace of a mind of a longer warranty may be worth the price.
  • What does the warranty cover? Be sure to read the fine print. Warranties usually come with two time periods: one for total replacement and one for part replacement. Also, the warranty doesn’t usually cover fees associated with hiring a professional to fix the repairs. Be sure to contact the manufacturer if the warranty is unclear.
