    • Efficient and Reliable Hot Water Solution
Size: 20 (kW) Style: Tempra Plus
Review Image by JWhatJwho JWhatJwho
Review Image by JWhatJwho JWhatJwho
The media could not be loaded. I recently had the Stibel Electron Tempera 20 electric tankless water heater professionally installed in my two-story home, and I couldn't be happier with the results. The installation took about four hours, including the addition of a whole-home water filtration system on the main line. The unit's performance has exceeded my expectations in terms of convenience and efficiency. First and foremost, the unit is impressively quiet, and its space-saving design is a game-changer. It doesn't take up much room, and the minimal noise is a bonus, especially if it's installed near living spaces. But what truly sets this tankless water heater apart is its ability to provide a continuous flow of hot water. I've tested it by running two showers simultaneously for an extended period, and there was no interruption in the supply of hot water. The heater only uses the hot water necessary, which is not only eco-friendly but also cost-effective. The temperature control is precise, ensuring that you get the hot water you desire without any fuss. I appreciate the quality of this unit, and even the licensed plumber who installed it mentioned that it's one of the top brands in the market. This gave me confidence in my purchase decision. I had concerns about whether it would deliver hot water everywhere in my house, but those worries were unfounded. My two-bedroom, two-story home now enjoys consistent hot water supply throughout. Of course, like any appliance, it's important to manage usage efficiently. Running multiple showers, a dishwasher, and a washing machine simultaneously might be a stretch for any water heater. However, with a bit of scheduling and planning, I've had no issues. I wash in the morning, run the dishwasher before bedtime, and take showers at various times throughout the day, ensuring they don't overlap. In conclusion, investing in the Stibel Electron Tempera 20 electric tankless water heater has been a wise decision for my household. It's efficient, reliable, and space-saving, making it a top-notch choice for anyone in need of a hot water solution. I also highly recommend having it professionally installed for peace of mind. It's a purchase that I'm truly satisfied with. ... show more

    • Top quality tankless water heater at a great price!
Size: 36 (kW) Style: Tempra Plus
I'd been looking to get a tankless water heater for a few years, but the unit prices plus installation were just too high until now. This Stiebel Eltron whole home electric tankless water heater was out of my budget until I found this open box unit price reduced by 48% of retail. This 2025 SE unit has a top of the line digital display panel that makes increasing temperature and gpm water pressure and flow adjustments easy and instant. You'll wonder why you waited so long. If you're a DIY person there are also multiple you tube videos about how to install and what's needed. The most important thing to know is that this unit requires 3-50amp dedicated breakers, so check your electrical panel before you buy any tankless heater as the amps needed vary based on the heater size and gpm's needed. I highly recommend this high quality Stiebel Eltron Tempra 36pro whole home tankless water heater as it produces 100°+ hot water within 1-2 minutes vs my old 75 gallon tank that caused me to wait 5-7 minutes and wasted several gallons of water before it reached the hot temperature I needed to bathe or shower. I can't wait to compare the savings, and I recommend this SE Tempra 36pro tankless water heater. The electrical wiring and installation requires an electrician or an experienced person to install this top of the line high-end, best in quality and performance unit. Thank you Stiebel Eltron for selling top quality equipment at a great price and free Prime shipping. You made this a 100% positive Amazon experience! ... show more

    • Four upsides and a downside
Size: 29 (kW) Style: Tempra Plus
For five years I've lived in this home with a 75 gallon gas hot water heater. It was in the house when I moved in and to be honest I've never had any complaints. Though it worked fine I decided to change out and because we are going solar roof next year I wanted to go electric. For the same reason we had gone gas furnace to electric heat pump for heating. I needed to decide whether to go electric tankless or electric heat-pump water heater. I went with this unit, the 29kw size. There are only two of us in the house so it seemed more prudent. We have several EVs and the largest tankless along with EV charging would be a fairly large load even for 200 amp service. First the upsides: 1. Unlimited hot water. Both of us can take showers at the same time. The only issue that two of us can have is if both of us want showers while the first cycle of the clothes washing machine is running. Minor limitation. Timing is everything. 2. Absolutely using no power when we aren't using water. We can go away for a month, walk in the door and take a shower and get instant hot water. 3. Accurate temperature control. We have two presets and one has been set for filling the soaking tub. Just press the button and then run pure hot water to fill the tub. The tub gets filled to perfection without figuring out the calculus of the mixing valve which changes depending on the temperature of the water coming into the house. This is a great feature that nobody told me about. 4. The house was originally built with what I consider a shortcoming. The hot water heater was located next to the furnace so it could use the same flue and gas connection. This is fine for ease of install but the hot water heater is on the other side of the house from where the hot water is most often used. Running the shower in the master bath or the sink in the kitchen required a full minute of water running to get hot water. We now installed the tankless beneath the kitchen where we use the water. No flue is required. This unit goes anywhere. Now we have hot water in a hurry where we use it. The downside. I once had a power failure that lasted several days. The water heater was the same as I replaced - used no electricity and vented naturally through a flue. There is something nice about a hot shower during a power failure. That will no longer an option. But then, I haven't lost power in five years. The only upside of the tankless heat-pump water heater would have been its (limited) supply of hot water during a power failure and its natural de-humidification feature. With everything considered, we went tankless. Just a tip, the most often warning I've heard with tankless is impurities in the water that can collect. To reduce this problem we installed a whole-house water filtration system after the water-softener and ahead of the heater. Note that I only gave tech support three stars - that is because I didn't need them so never found out about their quality. I did need power though and didn't have the required six circuit breakers that the unit required. I installed a 125 amp sub panel dedicated to the water heater. The unit has been flawless. It just works. ... show more
