Some tankless water heaters are better than others. Here's a quick guide to some of the best.

We've written many propane tankless water heater reviews, but at the end of the day, it all comes down to value. What will save my customers the most money? What will provide my customers with the most power? In short, what do we consider the very best products on the market?

Reviews of a sampling of the Best Propane Tankless Water Heaters

Here you can take a quick look at the features offered by the different propane models. 

I've put together a few propane tankless water heater reviews to help you make up your mind. Good luck, and happy hunting!

1. Takagi T-KJr2-IN-LP Indoor - Best of the Best

 When it comes to all-purpose tankless water heaters, it's hard to beat the T-KJr2-IN-LP. It's a cut above the rest in everything from power to price, and it's a unit that will be in your family for years and even decades to come. 

Why is it our top pick ?

Let's start with raw numbers. The T-KJr2-IN-LP is no slouch, delivering up to 6.6 gallons per minute (GPM) and requiring only 140,000 BTUs to operate. This translates to an 81-83 percent energy factor depending on where you live and how often you use your unit.

While none of these numbers are the individual best for propane tankless water heaters, it's hard to beat them when they're all considered together.

For example, other units may offer a higher GPM but require more BTUs, or they may have a better energy factor in exchange for a lower flow rate. The T-KJr2-IN-LP makes a name for itself by offering good numbers for all its features.

Speaking of features, you won't lack for those either. The T-KJr2-IN-LP comes with dials, remotes and inlet and outlet thermistors to ensure that you're always getting the best performance from your unit.

As I've said before, it doesn't get much better than the T-KJr2-IN-LP. While it doesn't offer the most impressive numbers on an individual scale, they all come together to make an excellent all-around unit.

It's also a unit covered by a certified Takagi warranty for 10+ years, so it's a tankless water heater that will not only give but keep giving for years to come.

Here's an overview of its specs:

- 6.6 GPM
- 140,000 BTUs
- 81-83 percent energy factor
- 6.7 x 13.8 x 20.3 inches
- 38 pounds

In terms of power, value, longevity and energy efficiency, the T-KJr2-IN-LP is simply unbeatable.

What's the Bottom Line?

All in all, I'd recommend the Takagi T-KJr2-IN-LP to just about everyone, and that isn't something I say lightly. Check it out on Amazon and see for yourself how much it can improve your life.


2. Eccotemp FVI-12-LP  - Best Value for Money

 Perfect for smaller homes and apartments, the FVI-12-LP is a great choice for those who don't want or need excessive amounts of hot water. While it's more than enough to handle 1-2 bathrooms at a time, it won't guzzle power just for the sake of having power.

Why is it our top value for money pick?

So what kind of performance can you expect from the Eccotemp FVI-12-LP?

- Its flow rate is 3 GPM, a number that's lower than average but still enough to run simultaneous showers.

- It requires only 74,500 BTUs, a number significantly smaller than other units that can demand upwards of 199,000 BTUs.

- It's 4 x 15 x 24 inches and 20 pounds, so it can be installed just about anywhere.

It should also be noted that the FVI-12-LP is a "point of use" unit, meaning that you can install multiple boxes throughout your home to boost their power. If you find that one FVI-12-LP isn't enough, simply buy another one! They're very affordable and not a strain on the budget at all.

Here's an overview of its specs:

- 3 GPM
- 74,500 BTUs
- 4 x 15 x 24 inches
- 20 pounds

Generally speaking, if you're in a small home or cottage, the FVI-12-LP is the tankless water heater for you.

What's the Bottom Line?

This is the unit you want for smaller homes and offices. Not everyone needs gargantuan amounts of hot water, and that's okay; the FVI-12-LP exists specifically for those who want to save money and energy with a unit that won't suck up power just for the sake of being powerful.

It's a unit that will serve multiple bathrooms at once and not make a big deal out of it.

Don't let its small stature fool you. The FVI-12-LP has been satisfying customers since it first hit the market, and you can see those figures for yourself on Amazon. Get clicking!

Expensive but the safest of all.

Families, this one is for you. The Takagi T-K4-IN-LP is one of the safest tankless water heaters on the market, making it the perfect choice for people with families or just general safety concerns.

For starters, it's a unit that allows for indoor installation. Many propane tankless water heaters have to be vented outside to prevent the build-up of harmful fumes, but the T-K4-IN-LP deals with those through a special condensing system that will keep you and your children safe as houses.

The T-K4-IN-LP also comes with several safety features like exhaust and water temperature controls. If you don't like what your unit is doing, simply turn a dial and change it.

Best of all, however, is the fact that the T-K4-IN-LP is strong enough to handle all the demands of the modern family. You'll receive upwards of 8 GPM with this model, and you'll still enjoy an 82 percent energy factor to boot.

Check out the T-K4-IN-LP on Amazon. If you aren't amazed by its power and safety measures, I'll retire from the HVAC industry.


5. Takagi TH3DV TH3 Series 199000

When nothing but the strongest unit will do, turn to the TH3DV.

Its biggest selling point is its flow capacity; you'll enjoy a whopping 10 GPM when you use this product, more than three times as much as other tankless water heaters on the market.

You'll also receive water pressure of 15-150 PSI.

Another excellent feature of the TH3DV is its internal condensing system.

Like several other Takagi models, it can also be installed indoors, so you won't have to worry about mounting it outside or installing expensive stainless steel venting kits.

What's the Bottom Line?

The absolute best thing about the TH3DV, however, is its self-diagnostic technology. It's a powerful whole-house unit that can regulate itself, and that translates into increased comfort and convenience for you.

Check out the TH3DV on Amazon. Let it wow you. Then come back and tell me what you think.

Let's cover the basics of tankless water heaters to make sure we're all on the same page.

What Are Propane Tankless Water Heaters?

Most homes have a hot water tank. It's usually located in a basement or closet, and it keeps hot water ready and waiting to be delivered through your pipes whenever you turn on your faucet.

Tankless water heaters work a bit differently. Instead of storing hot water remotely, it simply heats up cold water as it travels to your sink. This means you won't waste energy by keeping basement water hot for no reason, and it's also more hygienic since your water isn't sloshing around a rusty tank and picking up sediments along the way.

There are three main types of tankless water heaters:

  • Natural Gas
  • Propane
  • Electric

Pros

  • You'll save money. Without a water tank constantly maintaining the temperature of its stored, unused water, you can save hundreds on your energy bill each year.
  • You'll help the environment. Again, water tanks are big and wasteful, and tankless water heaters eliminate them entirely.
  • You'll improve the sanitation of your water delivery system. Say goodbye to miniscule particles inside your tank mixing with your drinking water!

Cons

  • Tankless water heaters cost a bit of money upfront. You'll have to consider them an investment for the future.
  • Since they heat your water using a live flame, propane units require special venting systems to prevent the build-up of harmful fumes within your home. These vents can cost time and money to install and maintain

As you can see, there's a lot to keep in mind as you browse tankless water heaters. Try not to make a hasty decision. Do your research and look at all factors before signing on the dotted line.

  1. Do any of these tankless water heaters have a way to work with hydronic heating and also domestic hot water
    I have a Polaris right now that keeps 180° hot water or 160 not sure that recirculates hot water to my fancoil area that heats the house and then I have her tempering device that temperature water back down to 140 for my domestic water for a shower . Do we need the tankless water heater’s work with that type of system

    • Hi Jim,

      The short answer is that it is possible to integrate the two. Rheem claims to have the only system of its kind manufactured by their experts, but it is entirely possible, in my opinion, that most tankless water heaters could be integrated with an existing hydronic heating system.

      1. Tankless Water Heater
      The tankless water heater serves two purposes in the hydronic system: it provides continuous hot water for use throughout the home. When a call for heat is made, the tankless water heater also acts as the heat-source for air handler, providing both hot water and heating for the home simultaneously.

      2. Hydronic Air Handler
      The hydronic air handler features a hydronic heating coil in place of either electric heating elements or gas-fired heat exchangers. When in heating mode, the hydro pump circulates hot water between the tankless water heater and the hydronic coil.

      3. Cooling Coil
      In Cooling mode, the cooling coil operates the same as any other heating and cooling system.

      We wish you the best in trying to make this work. Keep us posted. Happy Hot Watering! DEK

  2. Can a tankless be used inside double wide mobile home.

    • Hello Rick!

      A tankless water heater can be used in a mobile or manufactured home, single-wide or double, it does not matter. You just need to find the correct size and have the appropriate size gas line, or correctly rated electrical wire and breakers if you only have electricity. If you have a gas supply, simply choose the correct unit for propane (http://www.tanklesshub.com/best-propane-tankless-water-heaters-reviews/) or natural gas (http://www.tanklesshub.com/natural-gas-tankless-water-heater-reviews-best/) depending on what you have. Most of the brands we review, including names like Rinnai, Rheem, Takagi, and Bosch, all carry units that would work well with mobile or manufactured homes.

      Hope that helps! If you purchase and install one, I’d like to hear your story. We are in the process of putting up a new page on the site of tankless owner stories and would love to hear yours.

  4. I am looking to install a tankless propane hot water heater in a small cabin we recently had built on small island in Alaska. Needless to say, I am not going to find a certified technician to install the unit. I am moderately handy but certain not an expert or professional. The Takagi T-kjr2 seems like the best model. In your experience, how easy is it to install? I know that I am risking the warranty to install myself. Do you have any other suggestions?
    Thanks.
    Peter (e-mail pbunitsky@jwburns.com)

    • Hello Peter,

      I can certainly relate to wanting to install a tankless unit in your cabin, as I did that 3 years ago in my cabin in the mountains of Arizona. However, I had a certified technician install it. Our cabin has a propane tank which we only use for our heaters and now our tankless water heater. Since you are saying you have a small cabin, the Takagi T-kjr2 should work great. Installation isn’t too difficult, but you will want to be comfortable. The instructions found in this manual (https://images-na.ssl-images-amazon.com/images/I/D12vjBFf5XS.pdf) should prove helpful to gauge your comfort-level. Probably the biggest issue in installation is to make sure your venting is done right and that your vent has a back-flow preventer so as not to allow the colder air from the outside to flow back to the unit. It is often suggested to install your venting first to ensure you place the unit in the right spot. It is helpful not to have too many twists and turns in the venting.

      Hope this helps!

  5. Can Pex tubing be used as a hot water line or cold water supply to any tankless propane unit? I am looking at instructions for some models for a small cottage, 2 showers at once max use. Some of the instructions say must be copper or CPVC for the water line. Others say no plastic line, but have not seen PEX mentioned. Was planning on PEX, with sharkbite to copper to make it easier. But I could do all copper, as is the rest of the house.

    • Great question, PJS! Pex can be used. I had almost all my copper tubing in my mountain cabin replaced with Pex supplying all the hot water to my two bathrooms and kitchen. That said, you should always follow the manufacturers recommendation for the type of piping that affixes directly to the unit. What you planned sounds like a viable plan.

      Drain the Tank! Happy Hot Watering!

  6. Scott Rischmueller May 24, 2018 at 5:47 pm

    Question, what Company/Model/Unit did you go with in your Arizona Mountain Cabin? Any issues with elevation?

    • Hello Scott, I purchased and had my plumber install a
      Rinnai RL75iP Propane Tankless Water Heater. Altitude is not a concern, but since my cabin is at 7600 feet and the ground water is much cooler, I chose this unit because is has 7.5 gpm flow rate in warmer climates, giving me about a 5 gallon per minute flow rate at my cabin. This is sufficient for my two bathrooms and kitchen. I always have hot water. 🙂

  7. Hi DE

    Does the Takagi really need Stainless Steel venting?

    Cheers
    Dave

    • Hello Dave, Sorry for the delay in my response. Per Takagi’s Users Manual, there is NO specification that it must be stainless steel, but that is recommended for longevity/endurance, especially in cold weather situations. No one wants any leakage in their water heating venting and stainless steel is typically the best assurance against that. Hope this helps.

      Happy Hot Watering!

  8. I am purchasing a house that has propane as the fuel source and want rid myself of the hot water tank and burn up expensive propane just to keep a tank warm. The house is a 4 bedroom and 3 full baths, but only for my wife and I. We occasionally have guests and want to make sure they all have hot showers. I would like a unit with recirculating technology and that I am impatient waiting for hot water.
    What would be the best unit for my house?

    • Hello again, Jim,

      Apart from the number of bathrooms and the volume of usage, the next most important piece of information is the location of your home. Colder locations would require a bigger unit to produce enough gallons per minute to accommodate you and your wife and a house full of guests. Then you have to ask, how often will more than 1 or two showers be running at once? Also, where is the water heater in proximity to your bathrooms? Will the water heater be installed indoors (which would require proper ventilation) or outdoors? In my vacation cabin, which is in a cooler climate, I have two bathrooms (one with a shower and one with a tub). We installed the indoor propane powered Rinnai RL75iP (https://amzn.to/2JJkpFq). When we go to the cabin we usually have from 4 to 8 guests (sometimes up to 12) and we always seem to have hot water for all the guests. Since most people take showers, folks are taking showers one after the other or at different times during the day. That said, when I’m running the bathtub and the shower at the same time, there’s enough hot water generated for both. Therefore, I recommend at a minimum you get a unit that produces 7.5 – 8 gpm of flow in warmer climates especially since it’s just the two of you most of the time. The beautiful thing about tankless, is that even if you have 10 people taking back to back showers, you will never run out of hot water like you would with the old tank unit.

      As for having units with water re-circulation built in, there aren’t too many units or brands that have that capability. The better ones do not. Some lower priced brands throw that in, I believe, to make their heaters have other bells & whistles, but these generally aren’t known for the water heating functionality. Rinnai and Takagi are two of the best brands for whole house propane units: Rinnai RL75iP (https://amzn.to/2JJkpFq) 7.5 gpm, Rinnai RL94iP (https://amzn.to/2l2mX6C) 9.4 gpm, Takagi T-K4-IN-LP (https://amzn.to/2JJ9jQr) 8 gpm, or Takagi T-H3-DV-P (https://amzn.to/2LM5gnc).

      With regard to recirculation for instant hot water, my recommendation is the Watts 500800 Instant Hot Water Recirculating System with Built-In Timer (https://amzn.to/2t4zbzn). Because you don’t want to have hot water recirculating in your home all day and all night, which would make your tankless unit run all the time, this little, easy to install, very quiet, recirculating pump enables you to set recirculation to occur just before you normally take showers in your home. For instance, if you normally wake up at 6 am and shower by 6:15 am, then you can set your pump to only bring hot water to the tap beginning at 6 am , but ending at 6:30 or 6:45. That way, as soon as you turn on your shower, you will have “instant” hot water. At my cabin the tankless unit is in the same room as the downstairs bathroom with tub. The unit is approximately 10 feet from the tub and the shower is directly overhead on the 2nd floor. We need no recirculation pump as water is hot at the taps of both within seconds.

      I hope this information helps you in your decisions!

      Let us know, after you install your system, how it is working for you.

  9. I currently have an LP ventless water heater. I live in the country in Southern Minnesota. My local Lowes guy says I am not a candidate of a tankless heater. What are your thoughts?

    • Hi Janine,

      Given what you explained to me you can check out my Propane Tankless Water Heater Page at http://www.tanklesshub.com/best-propane-tankless-water-heater-reviews/.

      Given that you are in Minnesota and the ground water is cooler, I would recommend the following units that in warmer climates are rated from 9.0 to 10.9 GPMs. The lower would ensure you could run 3 showers simultaneously, while the higher GPM would ensure up to 4 showers.

      Takagi TH3DV TH3 Series
      10 GPM Check Price

      Rheem RTGH-95DVLP
      9.5 GPM Check Price

      Rinnai RL94eP
      9.4 GPM Check Price

      Rinnai RUC90iP (New)
      Rinnai is always improving as are the other companies. I haven’t had a full review on this unit yet, but it may be a good fit. 9.0 GPM Check Price

      Rinnai RUR98iP (New)
      Again, I haven’t had a full review on this unit yet, but it comes with a recirculation component on a timer that ensures hot water at your showers when you need it most. 9.8 GPM Check Price

      Rheem is a good brand and make a good unit, but Takagi and Rinnai are primarily Tankless manufacturers first and would advise you toward them first.

      Happy Hot Watering!

      Doug K.

    • Janine,

      Well, your Lowes guy I’m sure has the best intentions, but it really depends on each individual situation. So to clarify, you have a propane tank water heater that is ventless? Where is it located in your house? If you don’t have a way to vent a propane tankless water heater that you would put in your house, you can always get a ventless unit that can be installed outside. The trick would be to have it placed under an eave so has to protect it somewhat from the elements. The only reason I can really think of that would make your situation not conducive for a tankless system is the initial financial cost. Because you are in Minnesota (a cooler ground-water climate), you will need to choose a more robust unit to bring the cooler ground water up to the desired hot temperature. Therefore, if you determine the number of showers and sinks you regularly run simultaneously, I can recommend the best units for you. Let me know more about your situation.

      Yours,

      Doug K.

  10. Greetings Doug,

    We live in a rural area of WV and are looking to replace our electric water heater with a tankless propane model. We have been zeroing in on the Takagi T-KJr2-IN-LP, but wonder if this model is the right size for us.
    We are at 2400′ elevation and have a well to supply our water needs. The house is 1200 SQF, 2BR and 2BA. 95% of the time we only use one of the bathrooms, the exception being when we have guests visiting, so with a flow rate of about 6GL’s a minute, I would think that the Takagi should cover our needs.

    The are no service techs listed near where we live, so could a local plumber install it and not void the warranty?

    What are your thoughts?

    Thank you!

    Claus

  11. What kind and size of installation area do you need for a tank-less propane hot water heater? I would like to locate the new heater in the closet we had our old electric water heater in. Are there any safety
    procedures beside venting that are required or needed?

    What is a hybrid tank-less water heater? Is there a propane hybrid tank-less?

    Thank You

    • Hi Linda,

      Thank you for your questions. If you have an outside propane tank at your home, then you can install and propane tankless water heater. You can certainly install it were you had your electric tank water heater, but you’ll need to do two things: 1) run a gas pipe line to the location and 2) have the proper ventilation. You will need to follow all the safety protocols for any gas appliance. All tankless water heaters are smaller than any tank water heater so the installation area where you have your tank would be sufficient.

      There a very few hybrid tank-tankless water heaters on the market and can be electric, natural gas or propane. They are not at all popular, meaning that people either go with a tank or a tankless heater. The Hybrid is combining a storage hot water tank with tankless, on-demand water heater. It’s meant to replace a tank water heater with the same size unit, but with a tankless water heater attached. Rather than the water in the tank being heated by traditional rods, the water is heated by a tankless water heater. However, as with any tank water heater, the water in the tank needs to continuously be reheated every time it drops below the desired temperature, which means more energy is spent when hot water is not being called to a faucet. We don’t review these systems on our site simply because they are not truly “tankless” systems.

      Hope this helps!

      Doug

  12. Hi, I’m considering tankless, but my experience with a cheap electric model was that when you change the flow, it changes the temperature (or shuts off if the flow is too low!). Is this a problem with these propane heaters, or will they maintain the same temperature over at least a range of flow? ie, will I be fighting to adjust pressure and temperature at the same time while taking a shower or washing dishes?

    Cheers
    Josh

    • Hello Josh! I think you may have answered your question when you said “cheap” electric model. I’m guessing you might be referring to an under-the-sink model, but regardless, the reviews we have are for units that maintain the temperature throughout the flow, even on low flow, especially after the hot water reaches the tap. I have a Rinnai 75 propane unit at my cabin in the mountains, and I’ve not had any fluctuations in temperatures when washing dishes and running the shower at the same time. The unit’s rated flow rate is the key as per the chart on tanklesshub.com’s home page. Hope this helps!

      Happy hot watering!

  13. Hi, I live in western NC and am on a well with a 6.5 gallon per minute recovery rate. Our master bath has a huge 166 gallon jacuzzi style tub which we’ve never been able to use with our existing 50 gallon electric hot water tank. Its just me and my wife and the occasional guest. We have an external 120 gallon propane tank dedicated for a gas log fireplace that could also support the tankless hot water heater. Are any of the heaters you recommend have a pilotless ignition so that propane isn’t being waisted keeping a pilot on? Given our limited well recovery rate and need for high volume can you help narrow the possible propane tankless heaters? Thanks!

    • Steve,

      Most of the newer, gas tankless water heaters on the market do not have a “standing pilot light” so there’s no worry that gas is being consumed when the water heater is not in use, but electricity is typically required to ignite. For instance, Rinnai tankless gas water heaters have a direct-spark electronic ignition. Once the hot water faucet is turned on calling for hot water, the system immediately electronically lights and begins heating. When not in use no pilot flame remains. Therefore, the system will not work if the power is off unless it has battery backup. I did look for units that simply ignite from water movement (hydropower), but they are few and far between. Bosch makes one that does that, but by far the most efficient and reliable are those with Electronic Ignition, which would be most of the units reviewed on our site. I personally have a Rinnai unit at my mountain cabin and it works like a charm and isn’t burning fuel while I’m away from the cabin for sometimes months at a time.

      Hope that helps you.

    • Steve,

      Sorry for the delay in our response. It is good that you would almost have a dedicated propane tank. I want give you a thorough answer to your question. Most pilotless ignition models require electricity, but there are a couple out there that ignite with water flow. Stay tuned as we review these to ensure our recommendation is sound.

  14. Thank you for writing this post, I’m looking to replace my old water heater but there are so many choices that I don’t know which one is the best. Your reviews are very exhaustive and through it I can easily choose the device I want.

  15. Great to hear! Hope your 2022 is starting out well.

  16. Yes, I have chosen the right water heater for my family through your article. I will keep reading our website
