The era of tank water heaters has subsided and left us to a really hard decision: Natural gas, propane or electric tankless water heaters. I personally like the word electric and not just because it sounds cool in this situation.
The traditional water heaters with giant tanks have left many gaps to be filled because of their too many flaws and now manufacturers are trying their best to produce a product that will bridge those gaps. Thus, Electric tankless water heaters rushed to the rescue and, personally, I think that the competition with gas/propane tankless water heaters is very close. However, the electric tankless water heater still has the head start of technology.
We all know by now that tankless water heaters, of all kinds, will cost you more at first and truth is we are still intimidated by that. However, I believe that if we learned about the outcome in the long run, we would be more comfortable with the idea of upgrading. This is especially the case with electric tankless water heaters because the rewiring, the configuration and the expenses seem like such a bear but such is the price of improvement.
Electric tankless water heaters are a bit demanding initially. Nevertheless, once you are over the stage on installation, you’re on a highway that has no limitations. Once you go through the first expenses of rewiring (which are pricey) Installation should be a piece of cake (following the basic instructions). Not only that, but when you upgrade to a powerful electric tankless water heater, chances are high you’ll need to upgrade the electricity setup in your house.
One more thing, electric on-demand water heaters are much more advanced and even more economic. Unlike traditional water heaters, these ones do not consume electricity all day long non-stop, as they are only activated once hot water is flowing and deactivated once it stops running.
So, let’s look at some of your best choices on the market right now. (Target brand: Stiebel Eltron) (Note: Stiebel Eltron tankless water heaters must be installed vertically with the water fitting pointing down for best performance).

Stiebel Eltron Tankless Water Heaters Reviews
First Stiebel Eltron on this list is the Tempra 36 plus which is a compatible yet powerful electric tankless water heater which can easily produce a flow rate of 7.03 gallon per minute at 35 degrees rise. Here’s the thing about these tankless water heaters, they can provide hot water continuously at a steady temperature, so put your worries aside and just enjoy your ever-lasting hot stream. Speaking of temperature, the Tempra 36 has a digital temperature control which allows you to set the water heater to your most favorable temp and not worry about it dropping or rising surprisingly.
This unit is self ventilating and it won’t require any sort of additional ventilation. However, it’s always a good thing to place it in or near an open space for even better ventilation. However, be careful not to expose it to rough weather conditions.
Another good thing about this unit is that it comes with a 3 years warranty which is always a good thing. This thing has a longer warranty than most cars and warranty, for me, is the best way to say you can trust this product. However, for this warranty to be activated, you must hire a licensed professional to install the heater for you.
Another very reliable Stiebel Eltron is the Tempra 29 plus, and although it seems that it has lost 7 points compared to the previous on demand water heater, it can still cater for a whole house easily. Generating 5.6 gallons per minute at 35 degree rise, this tankless water heater will cater for a lot more than just a small home. Similar to the Tempra 36, this unit requires no venting because it comes with a built-in venting system but it must be placed near a window or an opening of some sort for maximal effectiveness.
Also, no more guessing games with water temperature because this tankless water heater is also equipped with a digital temperature control which is very accurate but most importantly, very reliable. The design is sleek and compatible which means you can install this unit pretty much anywhere you want (preferably near the house’s electrical mother board. That way you can save up on wiring because it’s the most expensive part).
Lastly, the Tempra 29 will do a good job saving up on your hot water portion of the bills which can accumulate up to a $100 of savings on a yearly basis. Technically, this on demand water heater will pay for itself eventually.
Next on this list is the Stiebel Eltron Tempra 24 plus which can easily be your best choice as it generates a flow rate of 3.6 gallons per minute at 35 degrees rise. This unit is considerably powerful as it can cater for a house of two bathrooms easily and keep that hot water flowing until you’ve had enough. The design of this tankless water heater is similar to most Stiebel Eltron Tempra tankless water heaters out there: it’s sleek and boxy and it can fit basically anywhere you wish it to go.
The Tempra 24 is also equipped with a built-in ventilation system deducing the cost of an external one and it also comes with digital temperature control to accentuate on user friendliness.
Simply, this tankless water heater is fascinating because it’s not that expensive and it can get the job done. Not only that but it also has a three years warranty when the product is installed by a licensed professional.
Fourth Stiebel Eltron is Tempra 20-B, which means it has lost 4 points compared to the last one and admittedly, this will be apparent performance wise. Nevertheless, this unit can still generate up to 2.9 gallons per minute at 35 degrees rise. Don’t get me wrong, that does not mean it will perform badly or it’ll come with glitches, it only means that it will not be as powerful as the previous Stiebel Eltron on demand water heaters. Nevertheless, this unit can easily cater for a small family with a house hold of one bathroom and the regular house chores.
On the level of utility, this tankless water heater is no different to its siblings. The Tempra 20B is equally equipped with a built-in ventilation system, its design is very slim and practical and the functionality options are still the same. However, this unit does not have a ‘digital’ temperature control, but it’s still pretty easy to set temperature to the degree you desire because the mechanism behind that is still the same. The only difference is that now you don’t have a little screen which tells you the current temperature.
Last but not least on this list is the DHC-E12 which is the most good looking one for that matter. This unit is small but efficient as it can provide a flow of hot water between 30 degrees C and 52 degrees C which you can control by the knob on the front. At a flow rate of 1.9 gallon per minute at 35 degrees rise, this unit can come in very handy.
This unit is perfect for single person or a couple at best but if you’re expecting more of this unit then you’ll be disappointed. On the bright side, most users prefer not to conceal this water heater once installed because of its small dimensions and attractive housing. (It looks like an alien robot).
Being small doesn’t mean it doesn’t come with a warranty. In fact, this water heater also has a 3 years warranty on parts which is almost unique in the whole industry and nothing says ‘we trust our product’ better than such warranty.
