DHX 15-2 Plus POU Electric Tankless Water Heater 14.4kW 240V

For a long time I have been an evangelist of sorts for what I call POUET - Point Of Use Electric Tankless. I have done it in three house. Basically, it means having an electric tankless at virtually every water source. That's between 4-6 units per house. I'm a believer in POUET's ability to save water and power. PIus I love-love not waiting for hot water. I published an article once on Green Building Advisor. Phew! Be ready for a firestorm anytime you speak out on anthing different. I have bought...I dunno... maybe 2 dozen different units in my quest. This one is by far and away the best. It works great - but most properly sized units do that. Besides the great graphical interface, what is amazing is that this unit actually controls (slows) water flow to achieve set temperature. Amazing! Finally! I have a very unusual floating house with long exposed water line. It's winter right now and the incoming water can be near freezing. I set the temp to 102 for a shower, then watch the screen as the unit slows the flow down and down and down, from a start of 3.5 GPM down to .9 GPM (last night). This is something I used to have to do manually and tediously. Truly amazing! There is one thing that I wish it did better: As I said, I have a long, exposed water line. In the summertime, the incoming water can be quite hot. This unit has a unique feature in that it has the ability to tell you that the incoming water is hotter than the set temperure. In other words, it has a inlet temp sensor, but it only comes on in "over temp" conditions. Why not tell the inlet temp all the time? Inlet temp is a useful piece of info for tankless. I hope that made sense, but it may be TMI.

My "handyman ain't got a clue what he's doing" water heater replacement project turned out pretty darn sweet kids! I'm very proud of myself for taking this project on as it had e-v-e-r-y-thing that intimidates me. Plumbing & electrical work are something I shy away from & put off as long as I can. I must admit that I never turned the main power off but felt safe while I did what I did inside the breaker box. Not proud but it's such a pain to have to reset everything once power is restored so I chanced it. I'd do it again as all connections were made outside the box. Once the connections were made I just snapped the flipped-to-off 60 amp circuit breaker back into place. Those heavy, black & white 6/2 wires on the right sure were a challenge to feed & loop the wire inside the box & then bend them into place like that though. Playing w/the temperature setting but right now it's set to 120* but I'm able to take it up to 140* if I'd like. Time will tell as to where we keep it set at. I thought it out, designed it on paper & then decided what & how much stuff we'd need to complete it. The last picture is of what I had left after completing the job. I'd call that an excellent idea of what was needed. No waste, that's how I roll. Those 3" long pieces of 6/2 wire is where I cut it a little long to get inside the water heater unit to wire it in. Those SharkBite fittings, pipe & connectors are a bit expensive but they're the whoop & make your plumbing a cinch. I mean look at how clean & professional looking that install is!!! I'm n-o-t a plumber & this was my 1st attempt at a project like this. Really looking forward to seeing what the savings will be as compared to a traditional tanked water heater that runs all the time. This is an on-demand type system & only heats the water when there's demand for hot water. It should be another 20-plus years before it needs any attention. Money back in our pocket is the way I look at it... #KillinThatKilowattUsage

I had my contractor install the unit. It required that 220 be run to the kitchen, where this unit is installed. I still have my propane water heater which feeds into this tankless unit. The purpose of this is to keep the unit efficient since it is electric and on grid after sunset when the solar panels aren't producing power. The existing hot water line (from the propane water heater) is a very long run and can take up to 7 minutes for hot water to arrive in the kitchen. This unit allows for this type of installation and by the time the propane heated hot water arrives to the kitchen this unit has been providing plenty of hot water which is preventing a lot of water waste, the unit automatically adjusts itself to accommodate the incoming hot water. We now have hot water within seconds vs. minutes. I have designed homes with several different brands of tankless water heaters but the clients wouldn't pay the amount extra that this brand costs. I decided to try in on my own project and glad to say this unit has been maintenance free and has had no issues, worth the extra money. This unit feeds my kitchen sink and dishwasher.

I bought mine used in excellent condition to save some money. I'm very impressed the way it works so far. Outstanding piece of equipment.

This provides hot water to a 600 square-foot little house. It supports hot water to a kitchen sink, a bathroom sink and a standard shower/tub. So far so good. It was incredibly easy to install - very lightweight. It has a very rapid response time. We’ll see what it does when the temperature drops down to 30°F or so here in central Alabama. (Roll Tide and War Eagle and stuff) 🤣

I installed it in our one bedroom bungalow that has one shower, one bathroom sink, one kitchen sink and a washing machine. It provides scalding hot water to all 4 receptacles. Needed to lower the temperatures as it was extremely hot. The furthest draw from the unit was 12 feet away with pipes that went from the unit across the exterior roof and down into the kitchen. Provided excellent on demand hot water. I purchased a backup unit for future use. I also hired a licensed electrician to accommodate the electrical requirements. I Highly recommend this unit.

Cant say that I've had the best experience with this water heater. I bought the unit for a bathroom remodel i was about to do so i could have a dedicated unit for the shower. I opened the box to inspect the unit when i got it just to make sure it wasn't damaged. The turn knob was laying in the box and damaged but i didn't think that was enough to go through the hassle of returning it. When i went to install it i noticed the sticker on the inside was listed as 12000w which was odd since the unit I ordered was a 15k unit. Once I got it all wired up and plumbed in the first use it would not maintain a temp. The power bar goes from 30% to 100% and back to 30% making for an interesting shower. It also makes an extremely annoying whining sound as it clamps down on the flow then releases and does that the entire time the unit is activated. I thought maybe it was too much flow as i was right at 1 gpm so i lowered the inlet down to get to a .2 gpm flow and it still does the exact same thing. Stiebel says due to it most likely being a returned unit from amazon they wont warranty it and Amazon says since its past the return date they will only refund a small portion of the cost. I really only wanted an exchange or the parts to fix i even offered to Stiebel to pay for the parts. Due to all this if you buy the unit from Amazon i would advise to remove the front cover and make sure the wattage sticker matches what you bought and plumb it in to test as soon as possible.

If you have the electrical capacity to have one of these its a must have. Instant hot water. I'm an electrician so I thought the hook up was fairly easy, as did my plumber. This is supplying water to a 1bdrm apartment with 2 sinks and one shower. All 3 can be running and there is no lack of hot water. I have a fairly light electrical load as all lighting is led, hvac is a mitsubishi mini split. The lights don't blink when this is in use nor does the ac bog down. While in use this actually draws 40 amps, with instantaneous jumps to 50 amps and immediately back down to 40amps. It is feed on #6 copper and is directly next to my panel so there is no voltage drop. Only had installed for 2 weeks but I'm highly impressed and hopefully it lasts a long time.

Excelente produto, ótimo funcionamento, mantendo a temperatura constante e com precisão. Bem acabado, leve, bonito e silencioso. Recomendo.

Muy buena calidad, buen tamaño y fácil de instalar
