3 Things They Don't Tell You About Tankless Water Heaters (On Demand Water Heaters) 

Glad you guys are back. Been there from the beginning

It`s Great to follow your Journey as before but without the Idiots that give you a bad time. People like that should stay away. keep up the great work you do i shall carry on Following you both with Family best regards

So glad I can see your videos again

I like my gas water heater with it's pilot light, the pilot light contrary to claims does NOT "waste" gas, in fact, that little flame is enough to keep my 30 gallon tank at the set temperature alone, until I draw about one gallon of hot water out, then the main burner comes on, but the rest of the time the pilot keeps the water hot. If I had the electronic ignition BS they sell now, that main burner would be cyling on and off 24/7 wasting even MORE gas than they claim the little pilot does. I dont know why you worry about that SMALL amount of "parasitic" heat in a closed utility room, in the cold months you'll be happy to have any BTU's that come from anywhere! My water heater is in the basement, it's insulated, I don't feel the outside of the tank is at all hot

Great content, super glad your back. You were missed. Stay safe .

I remember seeing you install that tankless heater and thought you were crazy. Personally I think a heat pump water heater is the best way to go. They are generally better insulated than regular tank heaters, and heat water much much more efficiently than a resistance heater. Plus, during the summer, they actually act as an air conditioner. In my first house I installed one in my basement which was half garage. During the summer it kept the garage at a nice cool 70 degrees, while heating the water for pennies.

Thank you Jesse very informative. Looking forward to future vids.

Yup We love our Ecosmart 27kw tankless heater but knew in advance to have a 400 amp service installed so we have no power issues. Immediate endless hot water for the win.

I thought the most important room was the kitchen?????? 😁

Boop Thanks for uploading more episodes!! To me Blissful moments!!

Great explanation! Do you have to treat the water coming from your well to keep it from having a hard water buildup in this system?

Amazing work. I love your house update videos!

I'm excited you are back, I've missed learning from you. Love to house.

its so funny in germany we have standart 100kw conections to the houses. its a 240 V to ground 3 phase system. In the hous where i grew up there where 3 24 kw tankless heaters. Its normal, hot water tanks are more of a rarity. Very interesting how different the systems are

Awesome information as always.

WOW Ya'll are back I missed YA!!!

Jesse great update

Thanks for another great video!

My tankless is built in that same "box" but different color, brand, and guts. Mine is also 199kbtu but rated at something just shy of 12gpm, stainless internals and no mini tank. I've had it for 6+ years and its been flawless with just flushes (vinegar). It's massively oversized for my home but should be able to run all hot water at once without issue in the house.

Good information.

Didn't you guys, at one point have a 3-Stage water filter for your well water?

i beleive all "tankless" hot water units have a 1 or 2 gallon water tank that is kept hot

Tankless units were used in The UK in 60,s

Take off the tape and the combi boiler reads HTP

And… so nice to follow the journey again! ❤

great up grade. Talk to your plumber about the anode rod in your electric water heater . should be checked every so often If it goes minerals will attack the tank & leak. Where I used to live I had to change every year . Alot of people don't know about this . Glad you guy's came back .

i'm another one glad u kid's r back.

Two littles? When we left there was one as I recall. But congrats of the family expansion. Glad you guys are back.

Been a journey - glad you're coming along one day at a time 👍🙏🇺🇲

Glad you guys are here!!

We missed you, we learnt a lot from you and then you were gone.

Welcome back

Amazing job Jesse, your mechanical room layout is topnotch and looks great. Hope your life issues have simmered down to a manageable level.

Careful with hot water loop with copper because at each 90 particles hit the wall with some force. Learned the hard way with in slab leak. Suggest looking at Upinor PEX with distributor Valve which feeds the outlet directly with minimal 90 angles.

Glad to see you back in the grove. Hoping this means your other troubles have been taken care of. Great job calling them out and taking care of business.

Rinnai tankless here. 199,000 BTU on propane. Just plugs into a 110v outlet. They are amazing. I have 2. 1 for our radiant floor heat and the other will be for domestic hot water with dedicated return loop.

You would not exceed 200 amps unless every element on range on max

i sure glade to se y-all back enjoy watching you and Alissa build your dream house . Been watching you all from the very beginning. We kelp checking on to see what happened to you.Very glad you found a way to solve the problem.If it take turning off comments I understand !

Great show

They make a system to circulates the water from the hot back through the cold until hot water is achieved. It can be activated with the same switch as the lights.

I have been installing 24 kilo Watts electric water heaters. These work fine for a 2 bathroom family of 4 households in the north east part of the country. A 36 KW seems like overkill. I can see you switching to natural gas anyways.

Are you still at the same stage in the build since before you left RU-vid? How does that function with kids?

True story... When my 5 girls were little and mom was a school bus driver, Mom would shower and leave, the girls would all shower and poor old dad would get no hot water from the 40 gallon hot water heater. I installed an Aquastar Tankless hot water heater and no more cold showers for me. Thanks for the memories Jessie!

Thank you for all your videos. Keep up the hard work.

I think you underestimate hot water usage with a family. A 50 gallon gas water heater is empty after two showers in my house.

Sure love you doing videos again ❤🎉

Keep up the good work love the videos

glad to have you back regulary and that you turned coments back on, fingers crossed that the skidmarks stay away.

Good to see you again. Lots of fun to come.

great video. thanks!

why not solar panels to ehat the water?

Thanks 🚿

In Europe (The Netherlands) we use two concentral metal pipes, cold input air through the outer pipe and hotter burned gasses through the inside pipe, you need only one hole through the roof and also some heat transfer to the input air. On the roof, the output pipe sticks out above the inlet for the input air to avoid circulation of burned gasses.

So glad you guys are posting again, i hope you keep it up. Sounds like we have some catching up to do!! The LITTLES sound so fun, i hope you two are ready for round 2 of this youtube thing!

Way too complicated for my reality. We have great quality water from northern Kalifornia plus sewer, electric and natural gas. You may want to do very careful research with regard to an exterior wood burner. From what I have heard, these use many times the amount of wood over having an interior wood stove.

Hi. Thats a nice looking technical room. Nice work! And thanx for all the information.

Excellent points, Jesse! Thanks for getting back to making great videos!

looks great. loving the build.

Jessie , it is good to see you again!

Thanks for filming Jesse! 👍😁

😊 Is there a “hot water on demand” for dummies? Talk to me like a fifth grader…

Doesn't the internal tank 9:42 represent a parasitic "cool" mode that you need to make up in the winter?

House update?

Jesse great update on things.

5:32 set up a clothesline and dry your clothes outside

Glad to see you guys back..

Love redundancy in systems

Thanks for the video 😊

Glad to see you guys back

👍

❤

glad to have you guys back

Nice system. We are getting gas on our road soon and we are getting ready to put in a system. We are finishing up a small duplex and will go with a heat exchanger tank for domestic hot water to have the capacity for both units. I’ll be putting in one of those circulating pumps to keep the water hot at both unit. I’m will be using 3/8” return going right back into the heat exchanger tank inlet. That’s a great price. We are going to heat our hydronic system to 130 F as our house is double stud foam filled walls. I have a friend that retired from a plumbing business he sold and he is going to do all my manifolds and setup.

I put in a tankless water heater water heater for my mother in the early 1980's. It used a metal exhaust pipe. Pilot blew out when the wind blew into the exhaust pipe. Didn't realize it until the heat exchanger froze. expensive to replace. Bought an automatic flue closer so it didn't happen again. I don't know if yours has something to prevent the cold from blowing in the exhaust but it sure is a worthwhile investment if it doesn't.

Very interesting and informative thank you. I’m so glad you are making videos again!! Love and blessings to you and the family! ❤

Amazing video as always. I always wondered if you ended up switching tour wanter plan since it used up so much space in your panel! Glad to see updates! Thank you

Glad you guys are back! Love your channel! Can't wait to start my own build with my wife.

It's great to have two you back. The videos that you produce really show how you decided to do something both pros and cons and are very useful as a result. I'm kind of interested to know if you considered heating the water using the boiler of your infloor heating and how that compared to what you ended up with. Those boilers are more than 90% efficient and you only need a water tank. Then you have one heater, can bring the air in and exhaust it out. Sure you don't have a backup to gas but you could back it up with a propane or just use propane. Add about 5k or more of solar with as much battery backup to get you through as many days without sun as you would figure to need for your area. Maybe if you're producing videos regularly, the solar and batteries could come out of that income. Solar's really workable these days if you can overcome the upfront costs. I know you had trouble with the batteries previously but maybe now they are better and require less maintenance.

Jessie is a perfect example of ,,,live, learn,,,practice, repeat = wow compared to Jessie of 2015!!!

Super fascinated to hear more about the mechanical room

Dito to what every positive comment is saying!

Just curious, what is the KERF logo?

Thank YOU for sharing.....

I love me some mechanical room

Is there enough room in case you have to work on or replace that pressure tank?

Really helpful video! We’re about to install a combination boiler so will disable the internal tank too. Like the fact that you tape out the non-contributing equipment companies. #followerfromdayone 😃

Alyssa & Jesse Missed you and your channel. Hope it 🚀 🌝 again. Cheers!

Nice to see you are back.

A few months ago my kids started taking their own showers and the electric bill spiked and mom and dad got some cold showers before we got them under control. I've thought about a hot water circulation pump too, but that seems like it would add to the thermal mass that the heater has to keep warm and would cause heat to leak into the walls of the house which would not be nice on those hot summer days. Maybe one that only runs in the morning and evening would be a good compromise.

Can I come over for a look? 😂

I'm pretty sure the intake T fitting should be rotated 180° so the open side is pointed down. That way when it rains it doesn't run down into the heater.

Welcome back! You have been missed in your absence. I am sorry that the trolls drove you from this medium. May they stay away from this time forward! I have the honor of upgrading both of my parents homes as well as my own from the 1920's. 1940's and 1950's.Your exploration into the current solutions to common issues will be invaluable as the upgrade process is applied in my situation. Thank you for coming back and closing these information loops.🦊Riki2Tails

I like being able to comment. Thank you.

Thanks for sharing your thoughts, ideas and videos. Definitely looks like you put some thought into developing this system. One small question, why the blue tape on the logos? One small suggestion, had a coworker that policed his sons shower time. Took a suggestion I gave him, put a 120v solenoid valve on the hot water to the shower and added a mechanical bathroom heat lamp timer switch to it wall mounted with the light switches, no where near the shower. His only complaint was it ran more than 10min. 😂 certainly glad he wasn’t my dad. Wishing you and your family the best. Looking forward to seeing more of your videos in the future.

What did you do with the old tankless unit??

Good to see you guys again.

good video!! and, glad ya'll are back!! Yup, the hype on these tankless water heaters caused many to jump in without doing any research.

You will have to pipe in a special hand valve circuit that you can turn and the water goes instantly cold! Or maybe be a nice Dad and make it where it just cools the water enough to give them the idea that Dad says shower time is over. Thanks for sharing. CB

This is so far away from the early days it's hard to link the two ... welcome back

Well done, I like it!
