Best Condensing Tankless Water Heater in 2022 – Reviews & Buyer Guide

These days, the best condensing tankless water heaters are all the rage. As a result, the topic of what is a condensing tankless water heater emerges. A condensing tankless water heater is a variant of the gas-fueled tankless water heaters. These tankless water heaters use natural gas and propane as fuel to power their operations. This leads to the second question: why was it given that name?

A condensing tankless water heater is named so as it doesn’t just heat the water using gas and propane combustion. It also uses the exhaust gases and vapors that arise as a by-product of Propane and Natural gas combustion. Using these hot vapors, the heat is transferred from the vapors to the water by a second heat exchanger. During this process, the exhaust gases and vapors cool down and condense at the bottom of the unit from where it is drained. Hence leading to its name.

Our Recomendation for Top Condensing Tankless Water Heaters

Best condensing tankless water heaters are known as the high-end but smart choice for a tankless water heater. The reason they are so popular is that being a gas tankless water heater allows higher and sustainable hot water capacity. Moreover, the cost of its operations is lower than any other tankless water heater which ensures the highest savings.

Dual heat exchangers are used in a condensing tankless water heater. Where one heat exchanger or the primary heat exchanger is responsible for most of the heating process of bringing the water to the desired temperature. The primary heat exchanger uses natural gas combustion to heat the water. On the other hand, the second heat exchanger is present preceding the primary heat exchanger. Hence the cold water first enters the secondary heat exchanger which heats it to a lukewarm level making it easier for the primary heat exchanger to do the rest. The secondary heat exchanger uses exhaust gases and vapors and transfers heat from them to the water.

As the condensing tankless water heater also uses its hot vapor to heat the water hence it can give a higher energy efficiency of above 90%. Unlike regular non-condensing units which only give an energy efficiency of 80-85%. This may not look like much but its effect becomes more pronounced in the following years.

A Condensing tankless water heater also faces the problem of condensate. As it removes heat from the hot vapors, the vapors condensate to form acidic water that can gather at the bottom of the unit and can damage the tankless unit. Hence, a condensate drain must be installed to flush this condensate into the drain.

    Buyer Guide: what to look for in the Best Condensing Tankless Water Heater

    1. Condensing VS Non-Condensing Tankless Water Heater:

    Gas tankless water heaters are available in two types: condensing and non-condensing. They use natural gas and propane to propel their operations. Typically, all gas tankless water heaters are non-condensing tankless water heaters unless they explicitly mention condensing. This is because condensing technology is still a newer addition to the market. As a result, non-condensing tankless water heaters are the most common.

    Let us go over some of the differences between condensing and non-condensing tankless water heaters.

    Condensing Non-Condensing

    1. It uses a dual heat exchanger* 1. It uses an only one heat exchanger

    2. Can work with PVC Schedule 40 venting 2. Require expensive stainless steel concentric venting

    3. It Gives an energy efficiency of 90-97%. 3. Able to give an energy efficiency of 78-85% only.

    4. It utilizes copper and stainless steel heat exchangers to combat hot corrosive vapor and fumes. Especially for the secondary heat exchanger which uses these fumes to heat the water. 4. Unless your locality has hard water problems, a cheaper heat exchanger can also do the work. It is safe from the risk of heat exchangers corroding from acidic and corrosive fumes.

    5. Tt is more expensive than the non-condensing water heaters as it uses durable and dual heat exchangers. 5. It is less expensive as it uses a single heat exchanger.

    6. Need condensate drain to drain the acidic fumes that condense as a result of condensing process. 6. Doesn’t need any kind of condensate drain as no condensing process takes place.

    7. Highest performance in tankless water heaters due to the working of its dual heat exchangers 7. It has a higher performance than an electric tankless water heater but less than a condensing tankless water heater.

    Note: * heat exchanger and heating elements are not the same. A single heat exchanger can have multiple heating elements. Hence a tankless with more than one heating element does not mean that it is a condensing unit.

    2. Condensate Drain and neutralizer

    A condensate Drain is an essential part of a condensing tankless water heater. So it becomes crucial to know that whether it comes with the condensate drain or you have to install it separately.

    A condensing tankless water heater will not function correctly without a condensate drain. The reason is that a condensing tankless water heater diverts the hot fumes and vapor produced by Natural gas or propane combustion to the secondary heat exchanger instead of expelling them outside. This way the extremely hot fumes (300°F) are used to transfer heat to the water using the secondary heat exchanger. This results in quick cool down of fumes, which upon cooling takes the form of cooled gases that are expelled through the vent and acidic water which gathers at the bottom of the tankless unit.

    From here starts the work of a neutralizer which neutralizes the acidic nature of the condensate. This is the way through which a condensing tankless water heater protects itself from damage from acidic water. While a condensate drain is needed to drain the neutralized water into the drain line. The condensate must be neutralized before it is drained or else it will corrode the drain pipes and damage your house plumbing system. So be sure to install a condensate neutralizer if it doesn’t come with the unit.

    3. Heat exchanger composition

    Normally, in a tankless water heater, the vents are the most likely to suffer from corrosion. Because of the hot and acidic vapor which are released through them to the outside. But this is not the case with a condensing tankless water heater. A condensing tankless water heater cools these vapors by transferring their heat to the water. While a neutralizer removes the acidic nature of vapors. Hence, you don’t need to use stainless steel vent pipe to exhaust the vapor anymore. A standard PVC schedule 40 can do the same job.

    In addition, the heat exchangers are the ones who suffer the highest level of corrosion in a condensing tankless water heater. As a result, the heat exchanger composition in a condensing tankless water heater must be examined. Heat exchanger made of Stainless Steel is the best to fight against corrosion while copper heat exchanger comes at second number to fight against corrosion. So, a condensing tankless water heater with copper or stainless steel components for a longer duration.

    4. Understanding a tankless water heater hot water capacity

    Most of the time, tankless water heater hot water capacity is misunderstood. Mostly because it is not properly conveyed to the customer. A tankless water heater can provide its claimed hot water capacity but only in certain circumstances. When the entering water is lukewarm rather than frigid. In other words, when the temperature difference between the incoming water and your desired hot water is not too much.

    Hence you can expect to get different hot water capacities based on this temperature difference. The same tankless water heater will give more hot water in a warmer region than compared to a colder one.

    The reason is that a tankless water heater cooks water to your desired temperature. Hence, if the temperature difference is less than the tankless water heater can do this quickly which results in higher hot water capacity. While a larger temperature difference will take more time hence lower hot water capacity.

    Now, the question comes that how can we know this without actually buying the tankless water heater. The answer is the Specification sheet. Each tankless model comes with a Spec sheet, you can also look it up online. In the spec sheet, you can see the temperature rise and flow rate chart that tells you how much hot water can a specific model of tankless water heater provide you based on the incoming water temperature. While you can find the incoming water temperature by putting the thermometer under a flowing tap or faucet.
