Best Tankless Water Heater Comparison Chart

What is a Tankless Water Heater?

A tankless water heater is basically a water heater that does not store hot water in a tank. Instead, this heater heats water as it passes from the source to the points of use, ideally meaning you get hot water on demand. Tankless water heaters are often small in size, sometimes small enough to be transported for a camping event. When it comes to prices, though, tankless water heaters tend to be expensive.


How Do They Work?

As already stated, tankless water heaters lack a water tank, thereby heating water as it flows towards points of use such as the shower or the faucets. The tankless models mainly rely on electricity, liquid propane or natural gas for heating. All of the above elements have their own pros and cons but natural gas and electricity powered heaters are the most popular in the market.
Technically, a tankless water heater’s performance depends on several things. The heater’s stipulated water flow rate, for instance, can guide as to how powerful or incapable a tankless heater is. Usually, the flow rate is measured in terms of gallons per minute, with higher flow rates indicating a better performance from the heater. On average, a good tankless water heater should be able to deliver a water flow rate that can supply the faucets, the shower, and the dishwasher.
All tankless water heaters use the same mechanics despite the fact that gas powered heaters tend to be more powerful. Usually, most heaters have a flow sensor that triggers the burner to warm the heat exchanger. As water comes in, it encircles the warm heat exchanger and leaves for the point of use when it is already hot as necessary. Gas powered heaters, however, release combustion gasses at the end of this process. For safety reasons, therefore, every home with a gas tankless heater requires a venting system to help eliminate the unwanted gasses.
Energy Efficiency

Tankless water heaters are undoubtedly great at conserving energy. For one, they lack a tank, meaning that no heat is wasted while the heater would be in a standby mode. On the other hand, energy star certified heaters are designed to have a secondary heat exchanger for improved energy efficiency.

Best Tankless Water Heater Buying Guide

tankless water heater buying guideTankless water heaters are increasingly becoming popular in the US and other countries where they were less popular in the past. Their great energy efficiency and cost effectiveness, in the long run, are the main reasons people now prefer them over the tank water heater models. Tankless models are also easy to install, even when your last water heater was a tank model. With that in mind, let us look at reasons why you should probably buy a tankless model as your next heater, and how you can effectively get the best tankless water heater at your budget.

Endless Hot water

When switching to a tankless water heater, keep in mind that you will no longer worry about running out of hot water in the house. You don’t have to wait for a half an hour as you wait for a heater to heat enough water for showering. Instead, your shower head, your spa or faucets can now have hot water at all times as long as you have the right tankless water heater in your house. The only thing you need to keep in mind, however, is that the best tankless water heater for your home will be one that can supply enough water for all your needs. And since we don’t compare tankless heaters based on gallon size, the water flow rate should be your biggest concern in this case.

Space Saving

Tankless water heaters are relatively smaller than tank water heaters. You can install the machine in a small space within your garage and have the rest of the space for other purposes. Their small sizes are as a result of the lack of a tank. Despite their small footprints, however, there are tankless water heaters that can’t be installed indoors for safety reasons.

Energy Efficiency

The most convenient tankless water heaters in the world are mainly tankless models. Their lack of a gallon tank that would waste energy while on standby mode helps tankless models save a lot of energy. In fact, the average energy efficiency rate of a tankless water heater is 80%, which is 13% more than the average energy efficiency in a traditional tank model. Tankless water heaters that are energy star rated are especially great energy savers, with some of them having an energy efficiency rate of 99%. In the end, someone with a tankless water heater can save up to $400 in energy bills per year.

High Quality

While an average traditional water heater can barely last for 12 years, the average tankless model will perform efficiently well for up to 30 years. With such long service lifespan, you can always offset the high installation costs with annual energy savings in the long run.
With the multiple benefits a tankless water heater provides, it is important to only settle for the best among the best whole house electric tankless water heaters in the market. A good water heater can, in any case, improve your home’s resale value. That is not the problem, though, but identifying the best tankless water heater for your needs at home. With that in mind, continue reading as we help you make the right choice for an appropriate tankless water heater for your home.

Gas Powered Vs. Electric Powered Heater

As you probably already know, the most popular tankless water heaters are either powered by gas or electricity. A gas powered heater is usually faster, more powerful and thus is able to deliver more hot water than an electricity model would. On the downside, a gas fired heater must vent combusted gasses, meaning you would have to incur additional installation costs for this purpose. Despite their additional installation costs, many people still tend to buy gas fired heaters. They are after all very reliable after all. But as you buy a gas powered heater; be keen to buy a model that does not require a pilot light for ignition. Instead, settle for a compact heater that is electronically ignited. Such models may be more expensive, but more energy saving in the long run.
Electric tankless water heaters, on the other hand, are cheaper, safer and reliable as well. They are also more convenient when you need a point of use tankless water heater, or when you need a portable heater for your summer house.

Size and Water Flow Rates

Think of a heater’s water flow rate when buying a tankless water heater. Tankless models don’t run out of the water after all, but instead, some of them may not have the capability to supply all the hot water you need at your home. Usually, a heater’s capability is measured in terms of BTU (British Thermal Units) ratings. In turn, these ratings determine the water flow rate a heater can achieve, and in the end, the number of showers and faucets a water heater can accommodate at any given time. A single shower, for instance, may need a flow rate of 2.3 gallons per minute while a sink 1.2 GPM. If you buy a heater with a flow rate of 6 GPM, you can, in turn, have a tool capable of providing enough water for two showers and a sink at the same time.

Tankless VS Traditional Water Heaters

Traditional water heaters are still very popular in the market. They are cheaper and advantageous in several ways. But are they any better than tankless water heaters? Well, it up to you to decide what water heater to have in your house. Read below therefore as delve into the main differences between tankless and standard traditional water heaters.
A tankless water heater basically relies on electricity or gas to heat water on demand. They lack a tank to hold pre-heated water but instead supplies hot water whenever you need it. A traditional water heater, on the other hand, preheats water and stores it in a tank of between 20-80 gallons. You can use that water for your showers, cleaning laundry or for washing dishes. When it gets depleted, however, the water heater begins to heat water again.

Tankless Water Heater Pros and Cons

Pros

  • Tankless water heaters are more energy efficient-In fact, studies show that you could save an equivalent of $200 or more every year on energy bills. Families that use less than 40 gallons of water in a day can, in fact, lower their energy bills by up to 35% as per research from Energy.gov.
  • Space saving-Tankless water heaters are much smaller in size, noting that they lack a gallon tank to hold preheated water.
  • Durable – An average tankless water heater can last for up to 30 years as opposed to traditional heaters that barely last 10 years.
  • Provides water as you need it-A good tankless water heater can supply enough water for your showers and sinks whenever you need it.

Cons

  • Higher Initial costs and installation

Traditional Water Heater Pros and Cons

Tankless Water Heater Installation

best electric tankless water heater
Deciding on what tankless water heater to buy is certainly not an easy job. Installing the water heater into your home isn’t simple either. Some tankless water heaters are actually very complicated, and making a mistake in the installation process can pose a great risk to your family. Most tankless water heaters, therefore, demand that you hire a licensed technician to do installation work for you. Fortunately, there isn’t anything the technician will do you can’t as long as you follow the installation procedure accordingly. In fact, you can effectively install your tankless water heater in the following quick steps.

Step One

  • Before you start installing the unit, observe a lot of caution in how you handle the supply lines and fittings that they will feed your heater. Ensure that your home is served with large gas supply lines (if the heater is gas fired). Check to confirm that the venting was done right or the electric on demand heater will be served by high quality wires. It is also advisable to use a special union connector as it helps with lime maintenance over the course of the heater’s lifespan.

Step Two

  • Turn off the water supply from the old heater supply system and in the main water supply system. Ensure you have a bucket near the supply line to collect water that is often left in the supply lines even after you switched off the main supply system.

Step Three

  • You will need a lot of keenness in this step as you prepare to disconnect the heat source of the old water heater. If the old heater was gas fired, ensure the supply valve is closed before making the disconnection. As for an electric tankless water heater, simply disconnect the appliance from the wall outlet. After that, disconnect the old heater and get prepared to install the new tankless model.

Step Four

  • Remove the tankless heater from the carton box, and place all installation accessories near you. Decide on the place to install the new heater and follow the manufacturer’s manual to install the heater accordingly. If you are installing a gas heater, ensure you have installed and connected the vent ducting system accordingly.

Step Five

  • Connect the water supply line and then switch on the gas supply line or plug it into a wall socket. Ignite or switch on the water heater and head on to the showers to check if you did everything right. Note however if the installation details become too complicated for you, call a technician immediately.

Tankless Water Heater Maintenance

tankless water heater maintenanceA tankless water heater can last for up to twenty years. With proper maintenance, the heater could actually survive another ten years to give you a servicer that spans over thirty years. And given how cost saving these tools are; there is no possible reason as to why you shouldn’t make the effort to clean up and maintain your water heater regularly.
Usually, gas tankless water heaters need more maintenance when compare to electric water heaters. After all, they have a burner that could get clogged or a supply line that could get clogged by minerals from hard water. A clogged burner is, however, more dangerous, and it could cause fires or burning the water heater. On average, you should flush your water heater after one two to years. This way, you can eliminate the most common types of minerals that clog apertures in the water heater and ensure that it lasts for as long as possible

Procedure to Follow

  • Turn off the source of power; either the gas supply or plug the tool from the wall socket.
  • Add isolation valves in the in/out connections and then turn off the water connection supply that serves your home.
  • Attach the correct hoses to both isolation valves and a to a 5 gallon bucket that will act as a descaler. Also, place a submersible pump into the bucket. Connect a hose one side to the sump pump and the other to the heater’s inlet. Connect another hose from the pressure relief point on one side and the other to the bucket.
  • Add vinegar or your preferred limescale remover to the descaler bucket and add a gallon of clean water. Circulates the content for about 20 minutes as the limescale remover eliminates any mineral buildup from your tankless water heater.
  • Shut off the pump and remove the inline filter for cleaning. If it is already worn out, buy a new filter.
  • Clear the bucket for any remaining lime scale remover before placing your pump back to rinse the heater.
  • Empty the bucket and fill with clean water. Switch on the pump and run water through its system for about five minutes.
  • Disconnect the hoses and the pump before you switch on the water supply line and the power source once again.
When cleaning an electric powered tankless water heater, make sure to follow every step guided by the manufacturer. Be keen as well when handling the heater’s wiring system, so that you can have an easy time reconnecting everything back once you are done cleaning your heater.

Tankless Water Heater Problems and Troubleshooting

troubleshooting tankless water heater problems
In the next five minutes, let’s explore some of the most common problems your tankless water heater is likely to experience. We shall also look at the causes, signs and possible ways to troubleshoot the issues. But before we even delve into the topic further, note that many tankless water heaters don’t really supply hot water instantaneously. However, if the water heater really delays in warming your water, there is a big chance you have a problem.

Lukewarm Water or No Hot Water at All

  • This is a common problem in many homes, but it is also easy to fix. To start with, check if the power sources are well connected to the water heater. If power seems to be okay, check if the flame rod in your gas water heater generates a spark.
  • Confirm that the water heater is served with cold water at the minimum or higher flow rate. Sometimes the tap could be delivering water at a very slow rate, thereby prompting the water heater not to work. The water pipes could also be frozen, in which case the heater can’t heat your water accordingly.
  • If water is supplied at lukewarm temperatures, start by adjusting the water temperatures upwards. If that method fails to work, reduce the water flow rate and later check the shower head or in filter for clogging. In fact, it is always good to flush the tankless water heater once in a while to prevent such encounters.

Too Hot Water

  • This problem is mainly caused by temperature settings. However, a blockage in the filter or a clogged shower head can also make the water supplied feel hotter than normal. In such cases, clean the filter and unclog the shower heads to clear the way for more water to pass.
  • Note to check the temperature sensor as well, as sometimes a breakage could affect water temperature control.

Bruner does not ignite

  • If you just installed the heater, check if the gas type and gas lines properly matched. If the problem happened after months of use, here could be more than one reason for the cause.
  • Confirm that the frame rod is operational and that the wiring system is not loose or damaged.
  • Check for a short circuit or a faulty flow sensor.

Noisy Unit

  • Check for debris in the fan
  • Ensure that venting in your gas heater is properly working.

Conclusion

The best tankless water heater can serve you for twenty years or more without experiencing any problems. However, failing to service your unit and to troubleshoot problems promptly can drastically lower its service life. And as noted in the above tankless water heater reviews, some problems can damage your unit in just a matter of weeks, such as a burnt burner. All the same, tankless water heaters are the only sure bet for someone who wants an energy efficient and a well performing water heater. They are also easier to maintain, and better yet they can serve you for very many years.
