What To Look For In A Tankless Water Heater

It is important to remember when looking for a tankless water heater that these devices are unlike traditional water heaters as far as their operational standards go. This means that regular standards do not really apply, at least in regards to storing water for later use. The greatest advantage, of course, is the immediate and unrestricted use of hot water at any time you wish with no waiting time whatsoever. That said, you do have to pay attention to how such a heater is built, how easy it is to install, and the way they perform over time.

Installation

This is one of the most important things to consider when buying a tankless water heater. You really do not want to spend hours installing the device and connecting it to your water line via intricate systems of pipes that take up a lot of work and the use of a wide range of tools. Instead, a tankless water heater should be very easy to install, so easy that you can even take it apart if needed. It comes as no wonder that some of these heaters are portable given how easy many of them are to install.

Flow Rate

Another thing to consider is the flow rate because it determines how much hot water they can produce over a specific amount of time. Measured in GPM (Gallons Per Minute), a tankless water heater’s flow rate tells you how much water it can deliver up to a maximum standard. We should point out that the GPM value tends to range from an activation flow rate, which is the minimum flow rate required to activate the heating function, all the way up to the maximum it can produce.

Compatibility

It has to be said that most tankless water heaters can connect to virtually any faucet out there, with little to no limitations. Even so, it certainly wouldn’t hurt to check if this is the case with whatever water heater you’re thinking of buying before you make the purchase. One thing to keep in mind in this respect is that the line has to be perfectly connected and that it shouldn’t involve any improvisations because the hot water will most certainly cause it to fail over time.

Temperature

The temperature rise a water heater is capable of is definitely a crucial aspect to consider for practical reasons. This refers to the change in temperature of incoming and outgoing water, mainly how quickly it happens. If, for example, you set the temperature to 100 degrees F with a 50 degrees F incoming temperature, then the temperature rise a heater should provide is around 50 degrees and no less. Keep in mind that a greater temperature rise translates into a lower flow rate overall.

Size

A unit’s size tells you a lot about how much water it can process at any given time and how much space it will take up once installed. A water heater’s size also indicates how much electricity it requires to operate at normal standards. Some units, for example, require no venting whatsoever despite operating on 36KW platforms. Then again, if you decide to invest in such a powerful heater, then you most certainly have a plan on how to use it and what for.

Features

You should also keep track of any additional features a water heater provides because they may end up making all the difference in the long run. Some of these devices offer a truly reliable flow control while others offer safety locks and fully controllable heating methods. To some extent, you can even use the overall set of features to choose between similar tankless water heaters.

Construction

This might be a bit tricky if you’re not accustomed to water-related installations yet very important in regards to a unit’s durability. Similar to traditional water heaters, you should pay close attention to the materials used in the unit’s making and how ingeniously it is built. At the same time, you should make sure that it fits well into the kitchen/bathroom without requiring that you remodel its surroundings.

Manufacturer

It is important with tankless water heaters that you pay attention to the manufacturer. Unlike other appliances, water heaters are required to be fully operational 24 hours a day, which requires them to be sturdy and reliable. When it comes to reliability, the brand makes the unit most of the time, and if you go for a well-renowned manufacturer, you are unlikely to get anything than the absolute best. The key thing here is to pay close attention to reviewers and what they have to say on the matter.
