Why don't you tell us how much electricity it uses

[@KateMcKittrick]

Hi Scott, Thanks for this tutorial. I live in a ~1400 square-foot, 2.5 bath house in the mountains of North Carolina where the groundwater is full of sediment and runs between 52 and 54°F. My house came with a titan N-180 electric tankless hot water heater (manufacturing date 5/15) that draws 75 amps on two 40 amp breakers. I replaced the well pump in 2020 after the addition of a spin down filter between the well water intake and the whole house filter failed to solve the problem of having to change the whole house filter frequently. The spin down filter seems to be doing its job (not much sediment in the whole house filter) but the hot water heater fails intermittently. I hired a plumber last week because the heater was providing lukewarm water. The titan N-180 has three elements, the first of which had a mild amount of visible external scale. The plumber reset the two thermostats, but also said they had not been tripped. For reasons the plumber didn’t understand, I had and still have hot water following this intervention. I am considering replacing the Titan with a Stiebel Eltron. The plumber gave me an estimate for a Steibel Eltron 24, which requires a minimum of two 50 amp breakers. The estimate did not mention the need for electrical work. The Steibel Eltron 20 would work with my two 40 amp breakers but, in this climate, could provide one shower at a time. It’s essentially the equivalent of the Titan and I may consider it. The other option is liquid propane (natural gas is not available here). I have some gas infrastructure in place because a previous owner installed a gas logs fireplace. According to the gas company, I would need additional infrastructure as well as venting and a 120 V outlet provided by an electrician. Also, I am aware that some states are banning new gas appliances due to environmental concerns and protecting the environment is important to me. Finally, the tech at Titan advised me to ship the heater to them in Florida for a $60 repair. That seemed very odd to me. I would appreciate your perspective. Thanks.

[@scottnra]

@user-ib6wi9yw8w well this will be a long answer lol. So as someone who is in an all propane home, with Navien LP gas tankless, I will always recommend gas tankless over electric 100% of the time! You’re asking more from that Titan than it can give without blowing its brains out every time it runs. The Steible Eltron 24 or 28 would be a better choice but you WILL have to upgrade the power. At that cost, you might as well just get your LP Company to put in a l in sightly larger tank and drop in a Navien. Rinnai has relationships with most LP companies and they are a good unit, but the Navien is better in a lot of ways. I’ll be detailing them in a later video (So subscribe! Haha) A LP tankless uses about 100 gallons of gas a year for the average family. Now about the environment concern. All of this electrification stuff is more about lining pockets of politicians. Think about this, our electricity mainly still comes from coal or gas. If we put solar panels on every inch of farmland in the US we could not power it. (and we’d all starve) All of the big solar farms in my state of VA are on…FARMLAND! (Bad idea big time) Offshore wind is killing whales although nobody wants to talk about that. (You can look that up online though about all the dead whales washing up during the winter months) The “Save the Whales” crowd are the same bunch pushing offshore wind! And don’t look up the pollution of what happens when they need maintenance or break down and dump oil in the ocean. Batteries for all these electric cars come from China and have a look at largest polluter on the planet…China. Strip-mining worldwide and killing forest and wildlife for that lithium to go into the batteries. (We’re supposed to look the other way on that too I guess) Clean burning, Low NOx gas has been the best way to power stuff and make heat and hot water for decades now, and we are the middle east of Gas! (There just is not nearly as much politician greasing for that to be attractive to them on either side of the isle.) I do hope that helps and also helps you have a look at what’s the other side of the coin for what they call electrification/decarbonization Thank you for watching!

[@Scuba_Bro]

A 36kw from Rheem actually does a solid job in the winter here in MA… but to your point running the electrical was a huge pain in the ass. I had to run 8 gauge for each of the 4 heating elements to 4x 40 amp double pole breakers. We only have 2 bathrooms and can run both showers with it at the same time for 11 months out of the year. If you live in an area like we do where it gets cold from November to March then you’re crazy to get anything less than 36kw and ABSOLUTELY make sure it modulates! My Rheem has been doing great for us in a 2100 square foot home

[@barrycheshier4219]

Great info for the layman! Best advice from you to me: hire a professional to size and install unit. What do you think about using a recirculating pump that can be switched on and off at point of use? Give it a minute to get the hot water to the point of use and then use the hot water. Seems like an idea that might work and save on wasted water and gas/electricity costs, too.

[@scottnra]

Those on demand systems work great. They have some that use your cold water line as a return as well. This one even has a timer on it so you can set it for your peak times and then have it not run at all. amzn.to/2KhzTUT

Scott Gregg 👍 the next vid might be too late for me...the tank heater is developing a pin hole stain and the wife’s getting nervous. The Stiebel still your recommendation? Two bath ,3 people 24W or 29W? South Florida location. Update: bought the Stiebel Eltron 29w (had HD 10% coupon) did the plumbing install myself and paid for electric install...all in less $2k even using all “shark bite” hardware, still more than a premium tank (which is what I wanted) but the wife was really into tankless. Set at 115deg. Wife is happy again.

[@joniloumckinster111]

[@scottnra]

with about 18 years selling, installing and fixing tankless water heaters, I can tell you if you can have gas...GET A GAS ONE! Preferably a Navien. That is the best one on the market today by a good measure. They are not cheap and they are not DIY, but you'll be very happy for a long time. Keep in mind I don't know you and can't make a nickel off this recommendation. Have a nice day and thank you for the comment.

The video is 6 years old. Technology has changed but this is one of the most informative videos I've seen on KZbin. Scott, you have a way of delivering hours worth of information in 15 minutes. My son, who lives in Stuart Florida (2 baths, wife and 3 daughters = high hot water requirements ) needs to replace his 50 gallon tank soon. No gas, 200 amp service. Tank or tankless considering 2024 technology? Thanks, Charlie

[@scottnra]

@charlie2265 Look into SioGreen. They are FL based and their technology is pretty cool. I wish they made one in a 28kw and 32kw unit for the cooler climates. As for the rest of them, there really has not been much in the way of advancement. They all still use high-watt-denisty elememnts.

[@mikep95133]

I like my Seisco. It's a 28 kw unit. Model RA-28. 4 heaters. A whole house unit. I wired it up myself. Our water is well water for our town, but it's held in 6 tanks up on the hillside before it arrives here. So the water is very warm in the summer out here in the AZ desert. Sometimes warm enough to take a shower with cold only water. The research I did on Seisco showed that their warranty response to a problem was superior to everyone else. That's my experience with them as well. Our unit is 3.7 years old and works fine. Far cheaper than propane !!

[@scottnra]

It may be cheaper than Propane there but it is reversed in other areas of the country. Siesco is a great unit for sure and thank you for telling folks here how well it's working for you.

[@mikep95133]

@@scottnra The other reason I switched off of propane was because every time there is a house fire here, it's propane related. I sure hope it's cheaper. $2.40/ gallon here without delivery fees, which are 50 cents a gallon, just seems far too high.

[@scottnra]

ours is probably about that here. But it takes less $ of gas to make hot water than electricity in my area. This is NOT true for all areas haha. I also like cooking with gas. I use about 300 gallons per year, gas range, gas fireplace, gas grill, two gas tankless, and an infrared in the garage. (A lot of it goes through the GRILL! haha)

[@mikep95133]

@@scottnra Natural gas is a lot cheaper than propane here. But we don't have gas in our town, only in the town 40 miles away. Our isolation makes propane so expensive. I love grilling with propane. That's about all I use propane for. My propane furnace eats it fast. So I went to all electric heating this past winter. Worked ok. Propane really heats well.

[@00varietyshowjoe]

Thanks for the video. I'm planning out my next house and was considering buying an electric tankless, but after hearing your explanation of water temp rise, I realize that my Missouri well water is going to be far too cold for this kind of heater.

[@scottnra]

Correct! Do yourself a big favor and look into the NAvien NPE-A model GAS tankless water heaters. Even if you have to run it on LP gas, you are going to be be much more happy with it than any tank. I live in an area without natural gas. I put a 500Gal LP tank in the ground and use about 300 gallons per year. We run TWO tankless water heaters, a gas fireplace, a gas range, gas grill, and a Ir heater in the garage. Most of your gas use is from cooking and the fireplace. The average home will use about 100 gallons of LP a year for hot water...endless hot water. The Navien's SS heat exchangers will handle your temperature rise and well water just fine. I hope that helps.

[@augustodasilva268]

Very informative thank you. Up here in Canada, gas is the way to go for the reasons you have pointed out. Also the cost of electricity here would make running an electric instant water heater almost prohibitive, not even mentioning the cost to upgrade the panel.

[@michaelhubbard9907]

Thanks for the info. We live in Maine, which leads itself to a gas-fired unit. However, we have solar heating (vacuum tubes on the roof) that heats a 300-gallon solar tank. The well water loops through that before going to the boiler. We are now installing solar pv, so I am still leaning toward an electric tankless.

[@scottnra]

STOP! I have news for you. The Navien gas tankless water heater has a setting that is for working with solar or geo systems. It will let you feed hot water from your storage tank THROUGH the Navien, and only operate the burners if the water is not already to the set point temperature! That is your PERFECT solution and there are no other tankless water heaters on the market built to run like that. Find a local Navien Expert and have them work with your solar guy. (Plus electric tankless would be a huge draw on your PV system you don't need.!)

Not done watching the video, 3/4 in, but this is seriously useful info to learn about! The bubble stuff makes total sense, and I didn't even realise some electric tankless heaters don't vary the heat output per element like you described here! Dang, need to keep studying. Thanks!

[@cdgarrett1]

I’m in Henrico VA on city water. I have a small 2 bedroom home to myself. The only things I use hot water for is the shower and to wash dishes. The washer I only use cold water. I’m going to upgrade to a 200 amp breaker box when I get the power run underground. The place I would mount the tankless unit would be a very short distance from both the kitchen sink and the shower, between them.

[@scottnra]

I'm in Hanover and been training plumbing contractors for years in the area. Most around here have little to no respect for electric mainly because they don't understand it. This means that finding a good installer can be a real challenge and even worse if it needs maintenance. You sound like a good candidate for it. You'll need to consult an electrician about the power. Personally I am a much bigger fan of gas but know not everyone has it available. If you have gas, Look at a smaller NAvien and overall you will be a lot happier.

[@cdgarrett1]

Scott Gregg If gas can be from a propane tank then maybe that may work but there is no gas in this community that I know of. I may also have to reconsider the location I want the heater installed. I was thinking it could be mounted inside the stud wall instead of on the surface. Plus it seems to need a separate breaker box other than the house panel box. I may have to see if it can be mounted inside, hidden in a kitchen cabinet like some smaller under the counter tank heaters are.

[@cdgarrett1]

Scott Gregg if you were offering me a job to be trained as an installer, thanks that could be a possibility if I don’t have to have certification or a license.

[@erwinbordallo]

Hi Scott! You should be an instructor! I live in a tropical climate and am installing an 18kW tankless electric water heater. Because this unit is not within sight of the Circuit Breaker panel, Irealize I need to provide a disconnect safety switch. My understanding for installation purposes on these type of units is that each heating element will require (1) 2-pole breaker for every heating element the unit has. If you have (1) heating element, you'll need (1) 2-pole breaker... If you have (3) heating elements, you need (3) 2-pole breakers, etc... Now, if you need to install a disconnect safety switch inbetween your breaker panel and your tankless electric water heater and say for simplicity, you have a (2) element tankless water heater, you will need a 4-pole single-throw diconnect swtich, right? The NEC says that all ungrounded cunductors shall make/break their respective connections SIMULTANEOUSLY. Therefore, having (2) separate 2-pole disconnect safety switches will not satisfy the SIMULTANEOUS make/break requirement. How is everyone getting around this dilema? You can find a 4-pole disconnect switch, but it won't be a light/general duty unit. The only ones I could find were of the Heavy Duty NEMA 3R type costing around $1500+ (Three times the cost of the water heater). The only alternative I see is installing a subpanel near the breaker and having your (2) 2-pole breakers contained within. Of course, you'll have to install an 80-100A branch feeder breaker as well as increase your wire capacity size to feeder sizes. How would you handle this? No one seems to want to answer this question leading me to believe the subpanel is the only feasible and practical way to go. Thanks for ANY input you can provide me.

Nice video. One complication with well water is that the flow rate is constantly changing as the pressure tank fills and drains. The water heater must constantly hunt for the right power level. My water heater does not slam on and off, but when it is running, I can hear the utility's transformer humming.

No= tank yes=tankless 4. is your tank in a spot where it can flood the house if it ruptures? No = tank yes= Tankless I hope that helps. Thank you for watching!

Scott, excellent info!! I live in S.

This heater has the following attached to it: two kitchen sinks, HE dishwasher, bar sink, outdoor sink, a single bathroom (w/shower, but rarely used, as it's a second guest bathroom), a laundry sink, and a clothes washer. Sounds like a lot, but it's rare any of those are used simultaneously and we don't use much hot water. Thanks again!!

Great information Scott, TYVM. What about "point of use" electric units? Say one per bath, one for laundry, one for kitchen? Tks

[@scottnra]

Winthorpe Good Question. By the time you pay for the units and all the new electrical work, you could have paid less for a propane unit for the whole house that would do a better job, and be easier to service. The main brands like Navien have local parts and trained service people. If you put something in that nobody knows how to or wants to work on, it's going to cost you later to replace them instead of fix them. Thank you for watching!

Scott thank you so much for the informative video and for the time that you put in it. It was on pint and answered lots of questions that I had. HOWEVER...... we just recently bought a house northern Nevada. Incorporated was two gas tankless water heater that served the entire three story. Mother in law occupies third floor master bath and bedroom. She has been complaining that hot water is not hot enough. With that said ... we are now renovating the master bath I see it as an opportunity to dedicate an electric tankless water heater for her. One shower head and 51 gallon bath tub. My question Scott is there any benefit to run existing hot water supply line to inlet of tankless heater? Haven’t found a heater yet in process though and doing my homework as well. I’m an electrical contractor and we will be hiring a plumbing contractor. Well water is as you said 45° F out of the tap. Out of the hot water tap we’re looking at 114° not hot enough for Mother in law. What is your take on this? I would be greatly appreciated for a little more of your time.

[@scottnra]

Aaron Casil What temperature are your tankless water heaters set at? There is not a human on this planet that can actually shower at 114/115. If you filled the tub with 114* water it would kill her. (Seriously) I think your issue might well be an adjustment on the shower valve. They have a scald guard behind the handle (if single handle) that allows you set the mix temp hotter! If single handle pope off the cap and look for a plastic piece with geared edges. Remove the screw, adjust the selector to a hotter position and put it back together. Let's start there first.

[@mmontgomery7069]

Take it from a licensed electrician.....if your breaker panel has enough spaces available, just add a 2 pole 100 amp breaker and install #2 SER cable (available at all local electrical supply stores). It'll have 1 black, 1 red, 1 white, 1 bare aluminum conductors in it. It'll save time trying to determine what you need for the tankless. Install a 125 amp 6 space main lug panel next to the unit. You're likely to need all 6 spaces to wire in the circuits to feed power to the tankless. Most of the ones I've hooked up required (3) 40 amp circuits for normal operation.

[@scottnra]

I always recommend hiring a licensed and insured LOCAL electrician to do that work. What if their breaker panel has enough space but is already at or over it's capacity? You can install a 100 amp breaker and run a 120 amp unit off of it through a sub panel? 99% of DIY'er have no business in their electrical panel in my opinion. Seems like a great way to help people burn down their house and void their homeowners policy... Please folks hire a local pro for that stuff or just don't do it at all.

Great video. We have a 16 year old 30 gallon electric Rheem tank water heater in very good and well maintained condition. However, the home insurance company says we must upgrade the water heater to maintain coverage. However, the utility closet is too small for todays water heaters because the manufacturers, in order to meet the new federal standards set in 2014, haven’t made a 30 gallon water heater small enough to fit. So we have to go to a electric tankless water heater. How many kW does a tankless water heater require?

[@scottnra]

It is going to depend on your area and number of baths in your house. Most likely 28kw or greater! If you are in the deep south, that's fine, if you are in a colder climate you need to look into propane gas tankless units like the Navien. You will be much better off in the long run. If you have to go electric, get one of these in the proper size: amzn.to/35iCry2

Ok, need a little help. I have an existing A.O. Smith EC 66 920 72 Gal. Electric Hot Water Heater. Would like to replace it with a tankless system.

The fixtures fed from this heater are; Master Bath: Ondine Shower system with Shower head-Shower Wand-3 Body Spray Jets, His sink, Her sink, Jacuzzi Tub; Guest Bath: Sink, Media Room Bar: Cup-sink. The Bar cup-sink and Guest Bath sink are sparingly used. At the Master Bath, it would be fairly rare that the Jacuzzi would be used at the same time as the shower, but it is possible that the shower would be in use at the same time as at least 2 sink. So that's what I'm holding as critical. I live in the Midwest, ground water temp charted at 52 Degrees yielding a water temp rise of 58-60 Degrees to 110. What size and or type of electric tankless water heater/system do I need or would you recommend?

Do you have a tankless electric water heater that you would recommend?

[@DeseretRider]

You misspoke (early on when addressing wire size and breaker size) --size 16 wire is extremely small---you can barely run your wrist watch on size 16 wire----You probably meant size 6 wire? which is rated at about 55 amps depending on the insulation of it's covering or sheath. The unit manufacturer will always list the amp rating of his unit and you must match that rating to wire size.

[@viper454545]

The guy said "a couple of number 6 gauge copper wires". Us in the electrical field know what he is saying. 70A breaker is absolutely fine on that. There is more to it for sizing wire and breakers which is why he recommends a pro, and I usually do to.

In your area, I think it work just fine. I'd still get a big 36KW model if you can. Might need some electrical upgrades, might not but it will give you a lot of hot water with your normal incoming water temps. This is about the best you can get in electrical Tankless: amzn.to/2U86620

You mentioned heating. I'm wondering if there is any system that will take an electric heater and use it as the driver for say a small house with 4-5 small baseboard type heaters? If so how small and unobtrusive could those heaters be and how do you design them? What kind of pumps would be required, activated how and how noisy? I have to admit the first videoI saw where the universal answer was don't do it yourself, your videos are full of good information. Thanks.

[@scottnra]

Definitely doable, but would take more than I can get into here. Everything to make that work already exists. It would have to be put together by someone that understands hydronics but it a simple HW Baseboard job with a Simple heat source. not a big deal Pumps are silent, relays click, Baseboard sometimes has expansion noise. No big deal. My thing about don't DIY it is simply because 99 out of 100 Homeowners (HOs) think they are better than they are and do about half of their homework before making a real disaster. I have seen a few HO jobs that were actually PERFECT! (but they are the exception not the rule.) The rest just b!tch about contractor pricing, screw up the works and then b!tch more when they have to pay someone to tear it all out and start over haha.

Scott, Thank you so much for this video! Even though it's over 3 years old, it is still very valuable and relevant information. Now may I ask you a question or two? (I hope you are still answering comments on this thread.) I recently bought a 2 bedroom, 2 bath condo in the Sarasota FL area. In the next several years, my wife and I plan to move there full time. Currently, it has a 38 gallon tank water heater installed on a 2 pole, 30 amp circuit. The condo building was built in the 1980s, with 150 amp service feeding the unit, and it's all electric - no natural gas. We have been looking at electric tankless water heaters and have softly landed on the EcoSmart 18, which is said to draw 75 amps. My electrician says the service to the condo won't support that size unit. What are your thoughts? Is that a good unit? Can you recommend anything better? Is a tankless even appropriate for that environment? Will my electrical service support it? Any other insights you may have would be appreciated.

[@scottnra]

Harold Crane Look up SioGreen and tell them I sent you! They are out of FL and the units look like a really great choice for that climate. They DON'T use immersion high watt density elements that will burn out eventually. As for power I'm not an electrician, but you might want to get a second opinion there. You may indeed need an upgrade. Thank you for watching!

Interesting info. Do you know if Rheem 18K offer Modulated power and or controlled flow rate?

@@scottnra I am interested in the Stieble one. The Rheem does modulate power but does not modulate water flow which sucks. I know I can get flow restrictors, but here in the north the water temp changes drastically from winter to summer, so I do not want a permanent device which will then impede me in winter. Keep up the videos :-)

[@gregsfishn]

Hello I recently had a rheem rtex 18 installed in my home and the unit works very well 2 showers no promblem at 112 degrees, my only issue is my lights flickering almost the whole time hot waters on. I was wondering if you think the Steibel Tempra 20 plus maybe a better option in this case and help the lights not continuously flicker while hot waters running?

[@scottnra]

Tempura modulates power better. Not knowing your house wiring it's hard to say but it should not do that. amzn.to/2PelDNr

[@christianleva4849]

Great video!I have a question for you. Can these heaters run continuously? Say 4-6 hours? Thanks

C C I don't do much with electric currently. As for Gas, I don't think anything comes close to what the Navien NPE-A model can do and in our climate would prefer gas almost all the time if possible.

hey scott, you have a recommendation in 2019? i've got a small 4 bedroom 2 bath house in sacramento, california. in the colder months (january to march ) the average temperature is 62° in the day, 44° at night

[@scottnra]

Check out this one. If your panel can take it, it should do great: amzn.to/2LDIb8s

[@mikeryan6277]

Good vid, I get the concerns about flow and understand that most shower heads deliver around 1.5 gpm so in the south ( Florida ) these will do well in a 2 bath home but how would it do in the same home as far as filling a Garden style tub? Way more flow from a tub spout vs a Shower head.

[@scottnra]

@mikeryan6277 In FL you can do a lot more with electrics than the northern tier states. Have a hard look at SioGreen. They are a FL based company and show a lot of promise in the electric market.

Very informative video. I, however, have purchased a 110v tankless point of use hot water heater and can't get it to work properly. We've even tapped into the hot water for the inlet to see if that made a difference as well. I just need it to work until the big tank reaches the other end of the house. Any clue what I may have done wrong? It's as though it's not even there.

[@scottnra]

Anna Lloyd 110V is not enough power to raise any decent flow noticeably. Classic case of manufacturer's overselling their products to consumers who don't know any better and are afraid to call a professional plumber. I know what you are trying to do.

Stiebel Eltron is pronounced "steebel" not "stybel". American here who lived in Germany for decades and worked on these units. These are good units. I would install a Stiebel over a Eco or Rheem. They have copper pipe internals that leak at joints. I Heat is a good one too.

Thanks for your concise information. I am looking at heating water for single shower and lav . thinking about Seisco RA-14 or Stiebel Eltron 230628. would appreciate your input. ground water temp in my area 67 deg

[@scottnra]

Hi John, Just from a support and service standpoint I'd go with the Stiebel Eltron but get a PLUS series. While that temp is pretty good, I don't know where you are but would rather go a bit more than not enough and the Plus" part of flow control is well worth a little extra upfront cost.

We've had several plumbers, with great reputations, that refuse to install electric tankless. They say that they require to many service calls over time. We currently have an electric, so converting to gas is pricey. We are home a lot during the day, but also get home together at night from activities and all need showers over an hour or so. What's your opinion? (We do have a gas furnace). We are in Maryland with 5 adults in the home. Space is an issue. We will be hiring a plumber but want to know what we're talking about.

[@scottnra]

There are a LOT of plumbers with great reputations that are still WRONG about tankless water heaters. Most of these have not taken the time to learn about them including how to install them correctly. A tankless water heater my the major manufacturers that require a lot of service calls was most likely not installed right to begin with. They are not for everyone but a person with a hot water demand like you have would be a great fit. Try Len the Plumber, or Tankless Concepts or go to the NAvien website and see if you can find a dealer in your area that is also a service provider.

[@farenlindsey1575]

I’m in northern Missouri. Need to run two showers at the same time in the evening. What type might you recommend that has the venting to avoid element burn out?

[@scottnra]

Faren Lindsey I would go with the Tempura+ always for an electric tankless application. You are going to need one with plenty of power for most of the year. This one should do a great job.

Hi, great video. We live in Plymouth Mass with well water feed. Inlet temp today is about 52 (don't kow what it would be in winter). Currently we have hot water that is heated through a coil in our oil furnace. We have a one bath house and have upgraded to 200 amp service. Have seen good reviews, including your video, on the Steibel Eltron electric heater. We don't have gas as an option so limited to electric. What size would you rec? Thanks, Mike and Maria Plymouth, MA

[@scottnra]

@mikea7350 I'd go the biggest you can given that water temp up there. The 36 here is as big as they come: amzn.to/3Jy3i9R You'll need some electrical work to power it correctly. You can also look at converting to a Navien Combi boiler on LP and ditching the oil all together to do both heating and domestic hot water. By the time you do the electric upgrades for the electric tankless and factor in your oil savings, I think you'll be money ahead! Thank you for watching!
