    • Great Water Heater - Different Functionality/Limitations.
Style: Tempra 29 Plus (Discontinued Model)
I am very happy with my decision to switch to an on-demand style water heater. This unit, SE Tempra 29 Plus, has performed very well during the first week of use. It is capable of running at 3.3 GPM with incoming water at 49 degrees F and output at 122F. This will fill my garden tub and run a shower at the same time, or run two showers and a faucet with the flow slightly reduced. Different functionality/Limitations- Please remember when you switch to a on-demand style heater that the flow (or max number of points of use) will be limited by the power rating of the unit; however, you will not be limited by the amount of time you can use the heater. I found this ideal for the garden tub as a tank style heater can fill the tub, but is then out of commission for about an hour. The same goes for showers. Two showers and a washing machines could be ran with the tank, but after doing this the tank was down for an hour. This does not happen with the on-demand style and it will continue to put out hot water as long as you want to run it. Minor temperature fluctuations with well water - I do notice small temperature fluctuations while using the unit. I believe these are associated with the pressure tank and cycling of the well pump. When the tank is charging (well pump is running), the water drops a couple of degrees (just noticeable enough to feel, not enough to adjust the water temp). I believe this is due to the water bypassing the pressure tank and coming directly to the heater. This incoming water is slightly colder than the water that has warmed up inside the pressure tank in the crawl space. This water then makes its way through the heater and reduces the output on the hot line side (because of the constant temperature control of the plus unit). The cold line side rises in pressure due to the pump pressurizing the tank and mixes slightly more cold water. I believe this could be eliminated by adding a buffer tank (5-20gal) between the pressure tank and house inlet that would allow the water to mix and acclimate, but this would only be added if someone was extremely sensitive to temperature variations. Some other positives: Easy installation. If you know plumbing and electricity this can be installed in an afternoon if your lucky with the placement of everything. It took me a weekend by myself to install. Most of the time was spent routing the power cables and mounting boxes. Saves space, No Footprint! This unit was ideal for my house. I had a 50gal tank in my half-bath and it was an eyesore and a space hog. The SE 29 was wall mounted on the garage side of the wall without taking any floor space and minimal wall space that wasn't being utilized. Others: Unlimited hot water, Better looking than a tank heater, and easily adjustable temp. ... 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
