    • Very impressive. Replaced a 75 gallon oil fired hot water heater.
Style: Tempra 24 Plus (Discontinued Model)
Having lived overseas for many years, I was familiar with tankless hot water heaters, but they were always gas. I was a little weary about an electric unit. After reading many reviews about the different ones out there, I went with the Stiebel Eltron. So far, I have been very impressed. FWIW, I have an 1800 sf older home in eastern PA. It only has 1.5 bathrooms, HE washer, and dishwasher. I have the unit set at 105 degrees. That is more than hot enough for what I need. Perhaps in the winter, I might need to turn it up a little. People has commented on Ytube and other places that water pressure will suffer, but I haven't found that to be the case. In fact, my water pressure actually improved. I'm not sure why. The only thing I could think of is that I installed this unit a little closer to the bathroom, eliminating about 8 foot of copper piping. Also some of the old piping or my old tank could of had some hard water build up. People have also commented about the water temperature fluctuating. I haven't found that to be the case either. I think this only happens with the non "plus" models. The "Plus" model has the advanced flow control that seems to eliminate the problem. Other people have commented about lights flickering. Once again, I haven't found that to be the case. I don't see why this unit would cause that. I would guess those people have some other issue going on in their panel or wiring. I did the install entirely by myself, including the wiring. I'll go on the record that I don't consider myself an experienced handyman, but I have taken a few adult ed courses and read a few books on wiring and plumbing. I also read the Tempra manual front to back, and checked the manufacturer's website for more information. I spent about another $300 at HD for extra tools, parts, and the NM 6-2 wire. I used Sharkbites for all the fittings. The hardest part for me was running the 6-2 wire from the unit to the panel and make it look clean. It took me a full day but I took my time. An experienced person will probably be able to do this a lot quicker. Contrary to what many people seem to think, you DO NOT need to use the Watts tankless heater service valves with an electric unit. In fact, the manual discourages it. The cold side of the unit has a tiny filter screen that needs to be cleaned annually, and the manual says it is best to use flexible stainless steel hoses to connect to the unit. Because I didn't use the Watts service valves, I did install the 3M Aquapure scale filter. This requires shut off valves before and after the filter, one of them with a drain plug, so keep that in mind when planning your install. You also do NOT need to have a T/P valve on the hot water side of the unit. There is a built-in T/P valve. However, if your local inspector won't pass it without one, you might have to install one for show. UPDATE (A Month later): Okay, it has been a month since I've installed this. So far it has been working great. However, I have an LG HE washer. I've noticed if you try to take a shower while the washer is running, there is some pretty dramatic pulsing on the water pressure. Also, because the HE washer rapidly opens and closes the hot water valve, it doesn't leave enough time for the copper piping to heat up to get hot water to the washer. This is not really a problem for me, since I mostly wash with cold water anyway, but for some, this might be a deal breaker. Running the hot water for a minute to heat up the pipes may also be a solution. A small tank with circulation pump might be another solution if you really need your wash water to be hot. A friend who is a fire fighter also recommended that a fire alarm be installed on the ceiling directly above the unit. He has responded to several house fires where the cause were cheap quality Chinese made units. Apparently, the cheap units sometimes catch fire. A fire alarm directly above the unit would have detected when the unit starts to smolder before a full on fire occurs. The Stiebel Eltron is a high quality German made unit, however, fire alarms are inexpensive and make sense as a precaution. ... show more

    • If you are comfortable replacing a circuit breaker
Style: Tempra 29 Plus (Discontinued Model)
We bought this 1 year ago and installed it in our house in mid-New Hampshire. Our house runs on a well, and I was concerned that the cold (40 F) ground water would create a challenge for this water heater. I was wrong. I installed this Stiebel-Eltron Tempra 29 Plus to replace a propane powered water heater that the previous owner had used. Our home was wired for electric heat in the 1970's, so it has a 200a service, and I wanted to avoid fossil fuels. We heat with 2 pellet stoves. We have back-up electric heat as well. I was concerned that the current draw for this unit would cause a problem with many electric appliances running at once. We didn't have a problem, even when we had guests and multiple showers running at once. Plus, the winter of 2013 was quite cold here with some mornings as low as -15F, and still no problems. I would consider myself to have above average handyman skills. I installed this unit myself and had no problems at all. If you are comfortable replacing a circuit breaker, you can install the electrical portion of this, but I caution you, if you aren't 100% confident, then hire a professional, because working near the bus in the breaker box can be dangerous, and 200a could probably cook you like a hot dog if your screwdriver slips. I have several years of experience working for an electrical contractor during the summers when I was a teen, so I felt comfortable taking on this project. I used shark bite fittings to plumb this unit. I got 2 valves to shut it off so it can be cleaned/flushed annually and I used 2 braided stainless steel connections to hook into the unit directly. I found these fittings on the shelf at Home depot. I also got the 8/2 wire at Home Depot. Total cost to install myself was ~$100 for wire (125 ft), ~$30 for 3 50a breakers, ~$60 for all sharkbite fittings. I had some other misc items on hand (screws, wire straps, tools, etc). My impressions of this unit over the year we have had it are very positive. There are some quirks, because this is not the type of system most of us are accustomed to as Americans. Contrary to the experience of another reviewer, I notice a slight, but noticeable increase in the temperature of the water when I'm in the shower and another tap is opened. It is not enough to scald, but it is occasionally uncomfortable. There is also a minor dimming of the lights when the water heater comes on. It does draw a lot of current, but not 150 amps. We have it set at 106F, which is the temperature I prefer in the shower. I can have the electric oven and range on, the microwave on, lights on around the house, the stoves going, and fill a pot with hot water in the kitchen. You won't have problems hosting guests. My inlaws were concerned that we weren't running the water hot enough to kill germs in the dishwasher and the clothes washer. I say hogwash. I haven't gotten sick more often or noticed dirtier dishes or clothes. The water at their house burns my hands straight out of the faucet. My monthly electric bill with 2 people living in the house is somewhere around $100. It went as high as $150. last winter with stoves and humidifiers going, and as low as $80 this summer with no AC running. I don't have previous bills to compare to since we installed this water heater as soon as we moved in. As always, YMMV, but I have been very pleased with this water heater. I probably could have gotten away with the unit one size down (tempra 24), but I like to do it once and do it right. The endless hot water and excellent efficiency are wonderful benefits, and we've had no significant drawbacks. If we ever move, I'll get one of these for our new house. ... show more
