Tankless VS Tank Water Heater...3 Myths DEBUNKED! - Twin Plumbing

I have a tankless water heater and I love it. It is true, you dont have instant hot water, but once you have hot water you have endless hot water. No more worrying about people using up all the hot water.

[@bobnothing4921]

I did dual tankless (they have a cable that they talk to each other through so only 1 is used unless the second is needed) and I've never hit a high enough demand to turn on the second tankless. I guess at least I have an automatic backup if one dies. That said, I need to replace my whole home water pressure regulator as if you run more than a couple of showers at a time you run out of pressure, so if I get my pressure issue resolved it might be enough load to trigger the second. I believe mine are 9GPM.

Don’t let this video scare you! While this info may be correct, there’s no beating a tankless water heater. Especially for large families. If anyone’s on the fence, don’t be. Tankless water heaters are Lifechangers. I have installed many of these and I’ve never had a single complaint. Everyone loves them. While it may not be instant hot water it is continuous hot water for as long as you need it. I have a family of five and we used to get mad at each other for running out all the hot water. That conversation ended 10 years ago when we installed our tankless. While there may be a little maintenance, it’s very minimal.

To avoid waiting for hot water and preventing the cold water sandwich, I have a tankless hot water heater that feeds a small (7 gal) electric water heater. There is marginal standby loss and because the water is already heated by the tankless, the cost to operate has actually been less than running a recirc pump. It's worked great, especially with 6 people taking showers in the morning. The setup is also used for in floor radiant heat - it's an open loop system and we haven't had any issues heating the house and taking showers, even when it's -10 out. An added advantage is the system is designed to pull heat out of the floors during the summer whenever we use hot water!

JB I kind of get what you're saying but can you give more specifics? I'm shopping for a new heater and like the sound of what you're saying. Thanks

[@JB-nf8nk]

@@bdyt Not sure what more specifics you're looking for... It's an open loop system with 2 zones. I use a Takagi water heater with 3 Armstrong pumps running the primary loop and secondaries. The hot water makeup runs through the radiant loops for a bunch of reasons and feeds a 7 gal electric water heater through a mixing valve. Radiantec has a bunch of examples of an open loop system that could answer your questions - my system is much different but the same in principle.

Tankless Bosch was a disaster for me in rural Montana. First problem was that I needed to upsize my flue a lot to meet installation specs. That let in lots of cold air in subzero temps which eventually froze the innards and caused a huge leak. Luckily it happened just as we got home from skiing and I was able to save the house. We also found that these were never really made for really cold well water. It just takes too long to heat vs some southern California installation. It would heat it up, but it took forever to get the hot water started at the bathtub level. This also caused a huge added load of cold water into our septic system. Good for city slickers in warm climates with tepid water systems. Not good for us.I was SO happy to get rid of the thing and go back to a conventional water heater.

The existing plumbing lines where it was installed were less than optimally routed. That caused at least some of the large delay I discovered and fixed that in a recent remodel. But I bought two electrics without even considering a tankless. There were also other issues to consider in our home with drafting and the creation of negative pressures caused by the huge flu required for the propane flames and how they reacted with our wood stoves. Never again for me. Hope you do better.

[@troyhickman8577]

We have both systems and we are on a well with a whole house generator. Our tank unit is a A.O. Smith (75 gallon ) and we have two Noritz tankless. Both systems have served us well but our water is highly processed. The conventional tank is used in our 4,500 square-foot home and the two tankless units are used in our detached 2,500 sf garage with guest quarters. One tankless is used for potable water and the other is used for a radiant heated floor with a glycol mix on a closed loop system. Both system are supplied from a 600 gallon whole house reverse osmosis system along with a Kinetico softeners, iron tanks to remove iron, calcite tank to manage PH along with a multi-stage filtration system, and chlorinator. Hands down I prefer the A.O. Smith! First and foremost, water quality is everything to a tankless water heater. The tankless are fine but are slow to heat. There is more maintenance with a tankless and they are far more costly to repair and/or replace. Our A.O. Smith is 16 years old and it still going strong, likely due to the reverse osmosis and having a neutral pH. Tankless water heaters are far less forgiving on water quality and can be temperamental if you don't have clean regulated voltage. Power surges can wreak havoc on them. Loose power, no hot water. Warranties mean very little and you will jump through many hoops in trying to make a claim. They definitely have their place and they work well in our situation. One last thing, tankless water heaters can leak as well. Hope it helps.

We built our house about 11 years ago. We put in a tankless water heater at the time. It's been great. We have 3 bathrooms and all can use the shower at the same time. I've done the required maintenance and have soft water, both important. We had tank heaters before and like this so much better.

I love my tankless water heater. It does take a little longer to get hot water, but it literally never runs out. It takes up practically 0 space, is stupid easy to install by yourself. I paid $1000 dollars for my rinnai, the comparable tank was $700. I did an interior install so I used the existing ducting and gas line. I love it.

[@vwspicer]

It is rare that the existing gas line and vent is sufficient for a tankless. Most standard natural gas water heaters 35 to 45 thousand BTUH. A tankless heater may be rated 180 thousand BTUH and requires a larger gas supply line. Some models also require special venting. You were lucky you could use the existing setup.

[@Balticblue93]

It is unbelievable with all the haters posting on here. There is no magic to install a tankless water heater as long as you follow code and some common sense. The math is actually quite simple and the home owners can pull their own permits around this area. Condensing units have a few extra items. I still prefer the concentric models that are mid efficiency. But I also install a recirculating valve, scale filtration system and a water softener. Rinnai or Rheem are the most popular in these parts. You can easily buy them online and not have to pay insane markup.

[@A-RonHubbard]

@@vwspicer There's no way on God's green earth he didn't have to change something on the supply and vent side of things. For starters, a gas powered tankless that uses over 110,000 BTU will need a 3/4 supply line and also use a 5 inch vent - either atmospheric or powered. No residential water heater I know of needs these things. They all use a 1/2 supply and a 3 inch vent line. Sorry, @iangreenlee2330, but I call BS.

[@dominicd4999]

Your video was great and informative and I agree with everything you mentioned. I am a licensed Refrigeration Mechanic and Heating Technician in Toronto Canada for 20 years. I also am Nate certified in the USA as I used to work for Lennox Canada. There are positive and negatives for both tank and tankless, but I will never go back to a tank after installing my Rinnai tankless. It is quiet, small/out of the way, I can get endless hot water after the initial delay, but most important, it delivers clean water. The amount of bacteria and calcium that builds up in a tank is incredible, especially bacteria if a tank is set to low. Tankless units MUST be maintained yearly and have a higher repair/maintenance cost associated with them due to the complexity and amount of components. Tanks also require maintenance, but are always overlooked. They should also be flushed yearly and T&P should be manually opened and closed to prevent calcium build up. I know are aware that tanks also require maintenance, you just left it out of your video. Maintenance/repairs/installation are a fraction for me compared to a homeowner, but my Rinnai has been running problem free for 11 years now. Companies I have worked for installed all tankless brands and I would ONLY recommend Rinnai. Great video.

[@Balticblue93]

@@accidental_relevance That is fair, my first house did not have a recirculating valve and it didn't bother me either. It took exactly 59 seconds to have FULL temp water in the farthest faucet. But once I tried the recirculation valve at a friends house, I immediately installed one. I think my next system will for sure be a Navien instead of a Rinnai or Rheem (even though I love both and have owned both, currently a Rinnai). I can understand your concern about the water, but remember it is being recirculating, so it is just sitting there. I am not talking you into it, just saying. But I also have mostly PEX, a full home house filter, a scale filter and water softener. Plus my LG refrigerator has a filter, so my drinking water is nearly perfect based on the two tests I have had done. Nice talking to you!

I spend my days repairing all kinds of hot water systems and do warranty work for a couple of brands. My biggest piece of advice for anyone looking to install/upgrade or modify a hot water system is to keep it simple. The more complex the system the more things can and do go wrong. An example is a domestic house with all of the following in one system: Solar roof panels (prone to damage from hail, icing, etc) run by a pump (can burn out, or have other issues such as faulty back flow valves) and control panel (burn out) attached to a storage tank (normal tank issues, leaking etc) with a tankless backup (PCB, fans, gas valves, water flow senors etc) Fitted with a solar tempering valve. (Require replacement every 5 yrs) This is a very expensive hot water system to install and will require a load of maintenance meaning you might never make back any costs from the installation before something needs to be repaired or replaced. An electric storage tank is extremely simple (it's basically an oversized jug) and cheap to intall and repair, even if requiring replacement (compared to tankless) Even a tankless system with the simple addition of a bathroom remote gains me so much extra callout work.

[@Moshavnik7272]

Our Navien tankless has worked perfectly for 5 years. We have saved on energy bills and and it has been worth it. Not having a tank to worry about how long before it starts to leak and needs to be replaced. This happened to us twice and both times in bad weather on a holiday! The tankless installation was done well and we also gained space in the closet the tank took. The only maintenance needed is a once a year vinegar flush. We have a water softener so we have much less sediment than usual.

[@TheFlatlander440]

I have a tankless water heater and love it. I will say one main advantage of a tank water heater with a battery igniter is when the power goes out (no generator) and you're on city water, you still have hot water. Found that out during Hurricane Sandy before I went tankless. We were out of power for 9 days but I still had hot water for bathing. Now I'm tankless and have a Generac natural gas generator so no worries now.

When I put a timer on the re-circulator pump to only run when we took showers in the evening or when we first got up in the morning it cut my electric bill by $70/month.

Your video leaves the impression that you think that installing a tankless water heater is not a good idea. A tankless is not for everyone. There are disadvantages over a tank type as you point out, but there are also advantages. A more balanced analysis would have been more helpful. What I like about my high efficiency Rinnai tankless is: 1) The cost of operation is much lower for our household of just two people 2) It takes up much less space in my small garage 3) It doesn't need to be turned off and drained when we leave home for months, and then relighted on return 4) It has a service life twice that of a typical tank heater (if flushed with vinegar yearly) 5) It's very quiet

You can use the pumps to circulate water to keep pipes hot but it costs a lot more in utilities than you might think. Hot water pipes aren't insulated and the added costs of running a pump. Just locate tank/tanks closer to the demand.

The main reason to go tankless is unlimited hot water, not cost. They require good water quality and annual descale, trap cleaning. A home owner can learn to do this if inclined. Combustion chamber needs to be cleaned also but frequency depends on gas, cleanliness of intake air and how well tuned combustion is. Heaters with flue pipes have high standby losses up the flue. Electric tanked heaters are efficient but can be very expensive to run depending on utility rates and have slow recovery. Indirect stainless tanks are the least maintenance, have almost zero standby loss and provide instant hot water if installed correctly. But they require a boiler. Point of use electric require large electric loads, scale up quickly and are usually not recommended.

I recommend against the recirculating pump. For a tankless water heater that requires the heater function to work almost full time completely eliminating the energy savings of the hot water on demand provided by the tankless water heater. If you want instant hot water, plan for an under counter heater. Much cheaper.

The recirc pumps have timers on them so you can set it to run only during peak times when you have the need for instant hot water keeping it from running all the time and putting unnecessary wear and tear on the tankless unit. Does hurt your overall savings but not that much.

[@jeffreymurdock8366]

@@nickgafa8527 just a hint on this thing you're saying and why it doesn't make sense. When the water is flowing the burner is on until the safety kicks in and shuts the burner off. At that point the water is hot enough to burn you. To restart the burner the water flow has to stop. All timers have a minimum number of minutes between events but you would only need about 1 minute of run time for the circulation pump per 10 minutes off time roughly. I believe the time minimum on pumps is 10 minutes. That is why a circulation pump isn't a good thing. On a regular water heater the water will never get above what you set it for on the tank. Now all this depends on the brand and model tankless setup you have but for the most part it's the way it goes.

[@rebeccabogardus4138]

I agree, with a recirculating pump the water in the pipes is being reheated regularly, effectively making your pipes into hot water storage, ie you have turned your pipes into a hot water tank! And with the volume vs surface area of the pipes compared to a tank I expect it would be quite inefficient to keep water in pipes warm.

The hot water heater was constantly flashing a code 11 when the hot water stopped. Had a certified repair technician come out to look at it. The expert simply said it could "be any number of things" based on the error code. Needless to say we never fixed the issue before selling the home. The take away is that if it works it is great but when you run into problems it can be extremely difficult to diagnose the problems with these. You could end up paying a lot of money in trip costs for technicians to figure the issue out by trial and error. The house was under warranty and even with all trip costs pre-paid they still never got it fixed for us.

[@georgesealy4706]

Recently my hot water tank began leaking after 15 years. So it had to be replaced. I chose tankless. First of all, tankless will be cheaper on a monthly basis because I am a single person in my home. With the tank unit I was heating the water 95% of the time for no reason. Now I only heat the water when I need it. The numbers: to replace the water heater with another tank unit was going to be $550 for the unit plus $720 installion. The units had a 6-10 year warranty period. The tankless unit plus the accessories mentioned in this video came to about $800, the plumber was $400 and the electrician to run increased power $650. So basically, the tankless unit cost about $580 more to install. However, with appropriate maintenance the tankless unit could last 20 years. I estimate the monthly savings in power to be $20 (because I am a single person). So the breakeven point to cover the additional cost of the tankless is about 2 1/2 years. For me, tankless was the best alternative. But for other situations, the conventional tank system might be better.

[@craigerickson1910]

Tankless unit last 20 years? I think that is super conservative. If you maintain it and flush every year or two depending on hardness of your water (check with your water company to get analysis) you should get 30 or more years from a modern tankless.

A couple significant things left out of this… 1) Tankless water heaters - properly maintained - will last 20-25 years on average (it’s not unheard of to see residential units lasting upwards of 30 years). Compare that to the average lifespan of a traditional tank-style water heater that lasts only 8-12 years on average and you’ll be spending far more money (not to mention time and hassle) on your tank-style heater over the long haul. 2) Tank-style water heaters can often leak causing hundreds, if not thousands of dollars in damage when they do. This is a risk that just doesn’t exist with a tankless water heater. 3) Tank-style water heaters lose capacity as they get older, so you’ll find yourself with less and less available hot water as the unit ages. 4) Tankless is just better for almost everyone. The important thing is to make sure you get a unit that will meet the demands of your living situation.

The building code requires that the water heater sit in a pan that is drained outside. If a leak does cause a lot of damage the house was poorly designed/built in this respect. A tankless water heater can leak and cause extensive damage if it is not outside or situated properly also.

If you still have this old water heater, it more than likely needs a new "dip Tube", that is the tube that takes the cold water towards the bottom of the water heater tank to heat it.

Thanks for the video. Been looking into tankless. I agree with the myths. Tankless do require more maintenance, could lengthen the time to receive hot water by 5-10 seconds (1/2" tubing within the unit times the length =? gallons of water to flush through) The savings was a little muddy in the explanation. The run for the gas pipe is the same for either tank or tankless. Both are going in the same location. Equal cost. Venting could be different. Tankless last twice as long if both systems are equally maintained. You are correct, the savings is 90% efficient vs. tanked 50% efficient has all king of factors that play with the numbers. One thing to think about is climate zones. Texas water is already 60+ degrees whereas Montana water is 45 degrees. This will reduce the flow rate because the tankless has to move the water slower to give it time to get up to 120 degrees.

It's a bit counter-intuitive on how to increase the water temperature when taking a shower if you have a tankless system...

After installing the tankless, that bill dropped to about $35. And that was using an %80 efficient machine. Saved $9,000 over 15 years.

When we moved to our present location, an urban condo, it has an electric 40 gal. tank. When it goes, a tankless makes no sense. It would require upgrading the present 30 amp supply, and the electricity savings would never pay back the costs involved in switching.

I went tankless, when the old one gave up, As handyman I did it myself. The unit cost me $200 plus 6 Ga Wiring and replacing to 50 Amp breakers. But if you have to hire someone or two, its to expensive. You are right to stick with the original sistem

[@johnnemesh5459]

I have a gas tankless. My bill last month for natural gas was $25. (water heater is the only gas appliance in the home) Yeah, it's REALLY inexpensive, and we NEVER run out of hot water. This has been a blessing...living with my brother and his gf, we OFTEN fought over hot water usage before this was installed. It also takes up SIGNIFICANTLY less space than the old water heater. Also, if you are charging people $1400 to install a $600 water heater, you are ripping them off, BADLY. Usually it's around $1000 installed for a $600 unit...and it only takes about an hour, MAYBE two of labor. Remind me never to do business with you guys.

We're about to install 3 tankless 3-Phase units in our house. One for the kitchen, mounted next to the sink, another bigger unit will be between 2 adjacent bathrooms serving them both and the nearby laundry and the 3rd will be a smaller one in the guest unit at the other end of the house. Position is key as our previous gas instant (tankless) heater was mounted miles from anywhere and we were using 5+ litres every time we needed hot water. Very wasteful. Now we'll get near instant heating at all taps (other than laundry) and unlimited for our family.

My experience with tankless in Mexico was not good. I had hard water and it caused a lot of problems with the tankless system. I also have a hybrid system with rapid heating and a small tank, it also develops mineral deposits fast because of the rapid intense heating. I prefer old fashioned tank water heaters, less cost and maintenance imho.

[@MrJamespeyton]

I installed a tankless water heater about 40 years ago. If I had a tank type heater, I would be on my 3rd water heater now. You really don’t need to maintain it if you have soft water. I have yet to flush my tankless water heater in 40 years and it’s still going strong. The 3 things you need for long life of the unit and efficient operation are: 1. A water softener, this prevents any scale buildup within the water heater and allows the water to heat faster. 2. A good water regulator. This provides a predictable flow rate because the water pressure remains constant. My water heater runs at a ideal flow rate of 2.5 g.p.m. and the water regulator allows me to adjust the flow rate due to a predictable pressure. 3. A good whole house filter. This will keep out sediment out water breaks which may occur outside the home. I use a carbon filter which also serves to remove chlorine. Another helpful tip would be to install a water pressure gauge upstream and downstream of your water regulator so that you know when it wears out. This will tell you the pressure entering your house compared to the regulated pressure. When the water pressure downstream of your regulator begins to exceed the set pressure then it is time to replace the regulator. With these conditions your tankless water heater can last a very long time with minimal maintenance. The initial investment is higher but if you plan on staying in your home for a long period of time, it’s well worth it. I know I’ve saved several thousands of dollars over the lifetime of my water heater.

[@USMC6976]

My son introduced me to tankless water heaters about 20 years ago. I bought a new house (brand new construction) and had them remove the tank and replace it with tankless. I built a new home and went all electric with my BOSCH electric tankless I paid $800 for 11 years ago. Installed it myself, and it is still going strong. It is fed from a well. It provides hot water just as fast as any tank would. Unless you are paying to circulate your hot water, there is always a slight delay between turning on the hot and getting hot.

The tank water heater versus tankless savings varies on the number of people in the house. My gas bill dropped by an average of roughly $60 a month when I went to a tankless set up. Now I only have 2 people in my place. The size tankless is determined by the number of bedrooms and people in the residence. For us a 12 liter minute water heater worked perfect. The original water heater was a 29 gallon. Also you have unlimited hot water with a tankless water heater. Also our tankless setup had to be adjusted a couple times a year to allow for temperature change. A more expensive tankless water heater has the ability to adjust the flame automatically to the temperature you set it at. In my opinion tankless is the way to go.

It used my current 1/2" gas line and had a built in external circulation pump that I had setup to run on a schedule. It lasted 13 years and I replaced it with the newest Navien model. I have it setup up with a motion sensor and relay switch to turn on the built in circulation pump when I walk into the furthest bathroom (the only one far enough away to need circulation for instant hot water). I love my Navien tankless water heater.

[@BrookBowenVideos]

If you install two tank style water heaters, side by side, you get unlimited hot water. Tank one takes cold water and warms it, and tank two takes the warm water and heats it. The only issue is that it takes twice the space but its a great solution if you want unlimited hot water. My bill stayed about the same.

[@kc9scott]

I’ve seen dual-unit tank heater systems plumbed both ways. In a house across the street from where I grew up, they have a pair connected sequentially like you describe. In my current apartment, they just have a pair of heaters plumbed in parallel to supply the whole 16-unit building. They’re just (commercial line) 50-gallon tanks with 40,000 BTU/hr input, which is IMO too small for the task. Still, that pair of heaters doesn’t do too bad a job. There are YT videos about the pros/cons of each approach.

We have a tankless water heater with 3 people in the house. To get hot water for showering, I have to turn on the tap (to the hottest) for at least 30 seconds before the water warms up enough. At that point, I reduce the temperature down to a warm temp and use. When it comes to multiple people showering one after another, it's great. When it comes to washing your hands or using water for less than 30 seconds, you'll only have cold water.

[@atomictyler]

that's because you have long pipes to your faucet. the same thing will happen with a tank. there's nothing keeping the water in the pipes hot with a tank or a tankless. saying one is worse than the other is just pure lies. I have a tank water heater and also have to wait for the hot water because the water sitting in the pipes isn't being heated and thus cools off, especially in the winter. If I want cold water in the summer I have to wait for the water that's been sitting in the pipes to clear out too, but I don't blame that on any type of system, it's just thermodynamics.

[@seanseoltoir]

I suspect that the mini-tankless units that you are talking about are the electric models, not the ones that use natural gas... I live in an area where we are subject to power outages, often prolonged outages due to hurricanes, so having natural gas for various things in addition to electricity is just a lot more practical... By splitting the energy usage between natural gas and electricity, my emergency generator does not need to be as large... Plus, by converting it to run on natural gas, I don't even have to have 55g drums of gasoline sitting around the house in case (when) we loose power... While my neighbors were sitting in their dark houses and taking cold showers after our last major hurricane for 2 weeks, my house was lit, I had hot showers, was able to cook, and could keep the sleeping area of my house air-conditioned to 70F... Maybe 70F would be considered a temperature that you try to *warm* up your house to in the *summer* in Scotland, but here in Texas with our heat and humidity, it is considered a nice chilly temperature...

[@michaelbrennan5433]

Install a water softener helps. Can install probably 3 water heaters over 30 years for the cost of 1 tankless water heater. Water incoming temp will skew energy ratings like in the northeast.

I used the KZbin College advice for the plumbing part and an electrician provided the professionally installed electric service upgrade. With the inspection and all that said and done it still came in way lower than another oil fired unit. If you are thinking of an electric instant HWH, your still going to need the 220v service. Using 1.25 gallon per minute shower heads, for a family of four, never ran out of hot water.

I have had a tankless water heater for almost 20 years and it is still going strong. I run white vinegar through it every year for about 2 hours…..very simple procedure. Hot water tanks have to be maintained too and won’t last 20 - 30 years. Here is a delay in getting the hot water but once I have it I can have my two teenage girls shower forever, wash the car with hot water when they are done, turn on the dishwasher after washing the car and then head up to take my own shower. Try that with a water heater tank. The only real downside that I have seen using a THWH is that if two people are showering at the same time I lose a LITTLE water pressure. I can live with that. My THWH also uses 74 watts to operate. That means I can EASILY power it with my generator during power outages (using a transfer switch). I would never go back to a tank.

We moved into a new house last year that was built in 2014, and it already had a tankless water heater. The "instant hot water" is definitely false, as it takes quite a while for most of our outlets to heat up, and we only have a 1 story house. In fact, we probably use more water simply because I end up letting the water run until it actually heats up, which can take seemingly forever (and also probably throws any savings we would have right out the window). I'll be looking into one of those re-circulators though to see if something like that could alleviate the issue. I'll also have to look at doing regular maintenance on it as well. Before we even moved in we had to replace the circuit board in it as it went on the fritz between the time we bought the house and we actually moved in, but I never even thought about doing routine maintenance on it. I'll have to look at getting a plumber out here once a year or so to check things over to make sure everything works properly.
