PRODUCT OVERVIEW

Model # Tempra 24

Internet # 203210873

Stiebel Eltron developed tankless electric water heating technology 90 years ago and continues as the industry pioneer and world leader. Our engineering and manufacturing tradition of excellence means you can depend on the performance and reliability of our products. Our Tempra models are whole house tankless electric water heaters, never wasting energy storing hot water, but delivering it as you need it, for as long as you need it. The compact design needs no venting, allowing for installation close to your draw off points, making your wait for hot water as short as possible and maximizing your energy savings. Tempra tankless water heaters are sized based on the number of bathrooms and your climate. Refer to the Tempra Sizing Guide under 'More Views' to determine which model you need. Call Stiebel Eltron at 800.582.8423 if you have high flow showers, or any sizing questions. Tempra water heaters supply water at a constant temperature from 86 to 140 degrees F that is settable on the front panel. We recommend setting the actual highest temperature you use, typically 107 degrees for a shower. Tempra Plus models incorporate an Advanced Flow Control that automatically reduces flow rates to deliver water at the set point even if demand exceeds capacity. Regular Tempra models do not have this feature and should be considered if this is not of concern. Tempra 24 models provide hot water for 1 or 2 bathrooms in warm climates, or 1 bathroom in cool climates.

  • Professional installation recommended
  • Tempra 24 models require 208 or 240 volt electric service, with a maximum draw of 18,000 watts at 208 volts or 24,000 watts at 240 volts
  • A minimum of 200 amp total service to the residence is necessary, with 2 separate 60 amp breakers and 6 gauge copper wiring for the Tempra 24
  • Tempra tankless electric water heaters are 99% efficient and typically result in savings of 15-20% in comparison with electric tank-type water heaters
  • Tempras use only the amount of energy necessary to heat the water needed
  • The sleek European design is considerably smaller than a tank, saving space and allowing flexibility to determine the best location for installation
  • Tempra units must be installed vertically with the water fittings pointing down
  • Tempra tankless water heaters work better than tank-type water heaters in hard water environments because they can be set to lower temperatures, which minimizes scale formation
  • Water connections for Tempra water heaters must be detachable (such as braided steel flex connectors) to allow periodic filter cleaning, including flushing for scale if hard water is present
  • Tempra tankless water heaters are ETL Listed for compliance with CSA and UL safety standards in the US and Canada
  • Tempra tankless electric water heaters are exempt from seismic code
  • Overheat safety protection and thermal protection reset are standard
  • See warranty for complete details of the 3-year residential and commercial warranty against defects in workmanship and materials under normal use

CUSTOMER REVIEWS

Rated 4.0 out of 5 by 14 reviewers.
Rated 5.0 out of 5.0 by perfect, as advertised I bought this tankless hot water heater because it was time to stop heating fifty gallons of water 24/7 when I really only need it twice a day. I did my homework and decided the Tempra 24 was most suited to my home (one adult, two teenage daughters, two bathrooms). Installation was quite simple; I did my own plumbing and electrical installation following the instructions. Within twenty minutes of finishing the wiring, I had bled the lines and my 15 year old daughter was in the shower—what better test? She emerged twenty minutes later declaring it an unqualified success, and she didn't even know I had washed the dishes while she was in the shower. It's been a month now, and the heater has met every challenge. Twenty years ago I installed a tankless hot water heater in a new home I built, and it was satisfactory, but had issues. There is simply no comparison—in both manufacturing and performance, this is light years ahead. I set the temperature at 116 degrees and it maintains it perfectly all the time. My main concern was warm water at the sink—since the sink is served by smaller lines, would I draw enough flow to activate the heater? Turns out I did, no worries at all. I've already urged everyone I know to go tankless when it's time to replace their heater—or sooner. And I will be pleased to recommend Stiebel. December 25, 2012
Rated 4.0 out of 5.0 by Met all of my expectations I had done extensive research before purchasing this product, and i am pleased with the results. i purchased this hot water heater 3 months ago, replacing my old tank water heater. I live in New England and this heater gets the water very hot reasonably fast. A couple of things future buyers should know before purchasing this item: It does require a 100 AMP service to run, and i paid $150.00 for the cables to run from my breaker box to the heater. You will also most likely have to pay a electrician to do the wiring, but it only takes about 40 minutes to get it hooked up. The plumbing is self explanatory and easy for someone with general knowledge of the trade. I only have 1 bathroom and my kitchen sink that need hot water (i wash my clothes with cold water) and this water heater easily does the trick, the one issue i had was that the volume of water going into my bathtub with the valve fully open was to much to heat, so if i want to get the tub full of warm water i can only open the shower valve half way. For the price of the product with the 10 year warranty it is a great deal. I saved $35 off my first months electric bill. April 23, 2012
Rated 5.0 out of 5.0 by So far so good Had this professionally installed with some new construction about 3 weeks ago and it is working flawlessly. We did upgrade to a 200 amp service for this to work. It does draw some power. When we turn on the hot water, we do get a very minor flick of the lighting. It supplies very hot water that does not run out. It is very easy to change the settings.It has been too early to tell about any energy savings on the electric bill. It does take a few seconds for the water to come out hot for some outlets located about 20-25 feet away.Overall very pleased. The only negative is we may take longer showers raising the water bill!

Rated 5.0 out of 5.0 by Very happy with this product The tankless water heater works as advertised. I replaced a very large tank type to save space. No lack of hot water, actually very hot! Watch your temp setting. We have a lag of 10-15 seconds in the morning shower before hot water arrives, not much more than the tank type. No cold water pulse during delivery as some have claimed. This heater uses a lot of energy when operating, but our first months bill was lower than other comparable months. I am very pleased with the unit so far, installed myself with no issues, and I hate plumbing! Thanks, Home Depot for carrying this premium product as well as all needed connections. Now, if I just hadn't purchased it the same week as the security breach....... September 25, 2014
Rated 4.0 out of 5.0 by Nice water heater I bought this water heater when the fitting on my old tank started leaking. Decided on this one just because i dont like running out of hot water. Any energy and water savings are just a plus. Before you buy make sure you have: room enough for 2 double pole 60 amp breakers, a 200 amp whole house service is required. Chances are you dont have 2 6-3 wires ran for your current water heater. So you might look and see how hard it would be to run the required wire. If you have or can get these things this water heater is pretty awesome. it was easy enough for me to install new breakers and run the wire. Mounting the actual heater is a cinch. Plumbing is super easy. As soon as i had it plumbed in i ran the water to get the air out. I Hooked the electric up and flipped the breakers set the temp on the heater went to the sink and was too hot to touch. I can run both showers, shower and dishwasher ect. without problem. I havent had it long enough to really say much about the quality though it does seem to be well built and really seems like a pretty simple concept. Overall i am pretty pleased with it.

Rated 5.0 out of 5.0 by Easy to operate, just watch the water flow and you''ll have endless hot water! Really good product. My Wife and I installed this water heater by ourselves, but we love doing house projects. One thing is we had to replace our main breaker box from 100amp to a 200amp for a $500 since only and electrician should do that, because you are dealing with the power line from the outside. Another note we had to call around a lot of electricians since most of them wanted to do the entire job for no less than $1500!!! Also the wires needed for the heater are expensive too. we spent an additional $200 just on the wires, they are thick and hard to work with, so if you have patient and not scared to work with panel breaker and wires it should be fine. We also did the piping for the heater and were easy to do. No leaks so far. The heater requires a water softener. After everything was completed, and after many counts to 10 to relax during installation, the product works great, we love the fact of not heating water that we don’t use. Two showers can be going at the same time with no problems of course minding the water flow! And that is easy to master. So depending of your do it yourself‘s skill be ready to pay an additional $600 to $1000 in installation possibly more. Love the products and takes no space, unlike our old ugly heater.

Rated 4.0 out of 5.0 by Great unit but you can only use one source at a time. Installed unit yesterday. Very easy to install (I am an electrician). However if you use more than one source at a time the water temp gets way too low (70 drgrees). My input temp is 49 degrees right now (FEB) I need the space in my kitchen for a remodel and will miss my old water tank. The good thing is I can shower forever without running out of water. The unit comes with 3/4" fittings but the tubing inside is only 3/8" so dont be fooled into thinking you will get great water flow. All in all it is a good unit and I will install a point of use under the kitchen sink to supply the sink and dishwasher from the cold feed. February 10, 2013
Rated 5.0 out of 5.0 by Awesome Product, Even Better Customer Support I accidentally broke mine, and even though what I did wasn't covered by warranty Stiebel Eltron replace my unit for free! I highly recommend this model if you are on a budget, and the Tempra 24 Plus if you can afford the extra $100. These units work perfect, are solidly constructed, and mine saves me close to 20% on my electric bill every month! August 12, 2013
