![Best Tankless Water Heater 2024 [don’t buy one before watching this]](/img/1.gif)
This was an exact replacement for the old one that lasted about 10 years. ruclips.net/user/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Simple and informative. Thank you for respecting my time.
thanks for the quick and fast guide! got a pretty rusty water heater when we bought the house so i got here while doing research on tank vs tankless :)
Thank you. Very informative.
2+2 is 4 -1 thats 3 “QUICK MAFS!”
That killed me.
Really good video too!
I just got an Stiebel Eltron DHC E 12KW For a one bedroom one bath apartment And I am frustrated because it’s good for a faucet but not good for a shower, however the water pressure where I live it’s insane, thanks to your video now I understand the importance about GPM, I will be checking on a Tempra plus 12. I reside in Miami. Thank you so much 😊
insanely high pressure or low in Miami?
Hi.... Using LP...., what do I need for single point of use, single bath?... Thanks
Installing an outdoor shower on a pool bathroom in Houston. What would you recommend from a tankless perspective? Gas, electric what model and size? I suspect the shower will rarely get used but the sink for hand washing will be used most often.
Thanks,
Electric could cost less upfront but if it will be installed outside there needs to be in some sort of shelter from the elements. The added cost of electricity might be negligible if it is not going to be used very often. A gas heater can be installed outdoors without venting, but on the off chance it gets below freezing out in Houston you will need to take extra precautions such as draining the unit and insulating the pipes!

lmao That 'Quick Maths' comment is gonna be under-rated. I seen what you did there.
I'm not sure if i need a meter upgrade, I'm getting conflicting info from different sources. I have a 250cf/h meter with 7" water column, the tankless unit is the first unit from the meter 40' away on a 1" black iron line. total btu requirement for the home is 330btu excluding the fireplace that is never used, 380 btu with the fireplace. rinnai, rheem, ao smith, and 3 plumbers I've called seem to think that upgrading the meter didn't make any sense, and that my current meter should support my gas requirements, only my gas company seems to think I need to upgrade.
You are the coolest person to talk about such stuff😆
the backwards lid looks dope yo
I'm building a new house. I want to buy an electric tankless water heater, but I am worried it will cause problems. Mainly, I want to put it in a small 3' x 4' room I will also use as a pantry, but NOT if an electric water heater emits water vapor/condensate that could create a humid environment that could breed mold. Would it be safe to install the electric tankless water heater in the small pantry? Or would I be at risk of creating a haven for mold? Thanks!
Hi, I live in the UK. I wanted to install Stiebel Eltron DCE-X 10/12 Premium electric tankless water heater in my bathroom to feed the basin and the shower. I talked to their technical team and they told me I could have any shower with this unit. Yet when I was about to install it, the plumber told me it was not going to be good enough for a shower. I contacted Stiebel-Eltron again, and they said that running the unit at its max capacity the best I'd get was 7 Liters per minute, which meant I could not have a shower that would demand more than that flow rate or I'd gate temperature fluctuations. The thing is that all showers on the market at a 2 bar pressure (which is what I have in my flat) deliver almost 20L/m. I'm very confused how Stiebel-Electron can then say their unit is suitable to feed a shower? Am I missing something? Is this unit not fit for showers? Or can I fix this issue installing a water flow restrictor in the shower? Can I even have a thermostatic shower with this water heater? I'd be extremely grateful for your guidance. Thank you!
There are shower heads on the market that have a flow rate of only 5L/minute. Just look for “water saving shower head”. As they are made for such low flow rates you may not notice much difference to a regular head. A thermostat is not really necessary because you can set the maximum temperature directly on the heater.
TFS!
Do gas tankless run at full capacity at all times or is there a point where the BTU throttle down ?
It should run at full capacity unless there is something wrong with the unit. I used to have one and it was great! me and my family used it for years without any problem.
Ll.p
I'm curious about the costs of running a central gas water heater as opposed to electric point-of-use tankless in the kitchen bathroom, and laundry room.
I know that one must consider things like water hardness and pH (softening systems) with the POA tankless but overall, how would you say the two systems would compare in cost?
Tell me more about your unit sizing

Thank you for your help.
I need either an Electric or Propane (perfer Electric)... to go into my Vintage Tiny Travel Trailer... Small Shower and Kit. Sink.
I need 120v... Do you have any suggestions?
I need something very small under the sink for hot drinks
Great Video... Excellent Information... (love your voice).
As far as the "Movement" of the video ... (I'm an Acting Teacher)... you need to
"Show more, than just Tell"...
What are some reliable brands to consider? I know Rinnai, but they are so expensive.
I'm looking at the Noritz AZ-SV (Japanese company which invented the tankless) & the Navean a close rival, also a Japanese made unit. Both have high grade stainless steel heat ex-changers but the Navean has a built in recirculating pump
What about electric amp requirements. Want one for the whole house and most require 150 amps and 36kw
Very true! Electric hot water heaters typically require a dedicated 30-amp, 240-volt breaker
Anybody out there? It is Dec 2022, I need help with if this is good for me
So by your calculation, I'm getting 5 gal.s in 100 seconds, 100 sec./5 = 20 sec.s, 20 sec.s x 60 = 1200 GPM!
You are just plugging gas models and knocking electric. With most homes now only needing hot water for showers bathroom sinks and intermittent kitchen sink. As washing machines, and dishwashers all run on only cold water feeds these days the direct hot water demand especially for 2 people or smaller households. They eliminate lots of unnecessary plumbing with traditional tank systems and much less to go wrong. Definitely way to go for lots of situations
It took 55 seconds for me to fill up a Home Depot 5 gallon bucket. So my output is a little over 5 gallons in 60 seconds or over 5 gallons per minute. Don't need to do the fancy math. Just common sense will get you there.
some people don't have common sense
Yeet
@@PEXUniverse
I have never SEEN ANY of these Tankless water heaters put out 5 Gal per minute! Have you PEX Universe?
@@PEXUniverse
Is this response... a Compliment or an Insult?
5 GALLONS in less a minute from an internal house faucet? What is your water pressure regulator set at, firehose?
This guy's got naturally wide shoulders. If he worked out he'd have a sick physique
Electric water heaters can use Wind and Solar power. But a gas unit can't
Cute as
Huh lol
Iron your shirt
To much trash talk. Get to the point
Your English is terrible - is that an Asian accent? I can't understand what you are saying.
Get an mature guy to present instead of this young guy who speaks too fast.
🙄
Ok boomer.
If he is talking too fast for you, you can change your video speed by tapping the 3 dots on the upper right hand corner of the screen. This brings up multiple menu selections. Tap the title " playback speed" & you can slow or speed up the video
Most of the time, I choose 2x ( the highest) but decreased to 1.5x this time so he was talking faster than most others!
Thanks, RUclips, for this option :-)
I don’t think he talks fast at all.
