When all you want is a reliable source of hot water, it can be more of a headache than you’d think to get it up and running, can’t it? I know the feeling because I’ve recently been there myself. No matter what I tried, I was always running out. Sure, my storage tank would refill and then give me more, but waiting is such a pain in the neck. I knew there had to be an easier way, so I set to work investigating what’s out there.

Luckily for you, I found and tested 7 of the best on the market, and typed up my findings for you to take a look at. That way when you want to shop with the peace of mind that you’re only considering proven options, you can! Right, let’s dive right into the first entry on my list and show you what you can expect from this class of water heaters!

Best Electric Tankless Water Heaters

1. EcoSmart ECO 11 Electric Tankless Water Heater

blank
The name of this thing attracted me because I wanted something that worked, and that helped the environment. Let’s take a look and see what I thought of it…

13 kW of power should be more than enough for you to get a hot steady supply

The 13 kW supply this thing brings to the table is more than enough for the task at hand if you ask me. I found no issues with it taking too long to get up to a temperature which was a welcome relief. If you want piping hot water the moment you wake up, then this could be just what you’ve been looking for folks!

Self-modulation is a smart idea, but how reliable is it?

I like self-modulation because it keeps your energy bills nice and low; something we could all do with! What I particularly liked is that you can only tell it’s operating by looking at your bills. By this, I mean that it didn’t interrupt the supply or produce lukewarm water. Well done guys, you’ve nailed it!

Lifetime warranty for residential use is great for your peace of mind

I love that this thing comes with a lifetime warranty because it shows that these guys genuinely believe in their product. For me, you just can’t put a price on this type of service because this is the kind of device you want to run for years and years. I found their phone support to be very friendly and knowledgeable, and I was never left waiting for answers.

A compact and robust device that will be easily installed by your contractor

The device is so compact and robust that anyone could install it really. If you want to get a contractor to do the dirty work for you, then that won’t be an issue in my experience. All of the fittings are standardized so they won’t require any fancy tools or return visits. Perfect for getting everything up and running in one quick visit! Highly recommended for those of you who want a device that makes your life easier.

2. Stiebel Eltron DHC 3-1 Electric Tankless Water Heater


It’s a second entry for these guys and it’s probably no surprise for those of you that have used them before. Here’s how their second offering got on when I put it to the ultimate field test.

50% more efficient than a storage heater

The efficiency of this thing was unbelievable which will come as a relief to those of you looking to cut your energy bills. It’s an incredible 50% more efficient than a storage heater because it only heats when you need it to. That is perfect for making your home more energy efficient while also ensuring you never have to wait for your hot water to kick in. Highly recommended in this respect!

High limit switch is a simple yet effective way to prevent dry fires safely

I like how simple it is to reset the high limit switch. These things are there for a good reason, and without them, there would be a lot of severe consequences. That said, if they ever do trip, you don’t want to be reading the manual for half an hour to figure out how to reset it. These guys have struck the perfect balance between safety and usability in my opinion.

Cheaper to install than a tank unit, but how long did it take?

The installation was cheap, and in no small part because it only took an hour to get up and running. If you hire a contractor to set it up for you, then they’re not going to be able to invoice you for very much at all folks. Welcome relief for those of you that are undertaking this type of home improvement for the first time.

Hydraulic control meant there were no annoying sounds in the middle of the night

The final thing I want to draw your attention to is the quality of the hydraulic control. It’s a great piece of kit that results in a near silent operation day and night. That is fantastic news for those of you who have grown tired of being woken in the middle of the night by annoying humming and whirring as the tank kicks in.

3. Atmor 3kw110v SINGLE SINK 0.5 GPM Point-Of-Use Tankless Electric Instant Water Heater


This is a new name for me folks, but that certainly didn’t put me off. Here’s what I thought…

A small and compact unit that works perfectly under the kitchen sink

The first thing to say is that this is a unit that will fit just about anywhere you need it to. That is great for those of you who like the idea of using it under the kitchen sink. With a standalone heater that ensures you can always get hot water in the kitchen your life could be that little bit easier!

Pressure relief device comes as standard which should make your life easier

I like that pressure relief is now a standard feature. Without it, you would have to manually vent your heater to avoid it overheating which is not something everyone would feel comfortable doing. This little addition makes it a virtually install and forget purchase in my experience.

Reduce the flow rate to increase the temperature: so simple!

As with all the entries on this list the slower the flow rate, the hotter the water. I like that these guys haven’t tried to do anything fancy to try and make a name for themselves in this respect. In my opinion, great design should go by the maxim of if it isn’t broke, don’t fix it. By creating a standardized design that is easy to install and operate they’ve done precisely that.

I was able to install it in less than an hour which was really impressive

The installation time is a testament to the simplicity of the design in my opinion. That doesn’t mean that it lacks heating power or storage capacity — far from it! What I mean is that all of the connections are standardized and easy to work with. These little bits of thoughtful design make all the difference when all you want to do is get your new purchase installed. Highly recommended from me to you.

4. Ecosmart POU 3.5 Point of Use Electric Tankless Water Heater


This is a clever little unit that has been making a lot of noise in the industry for all the right reasons. With that in mind is it any wonder it’s made it onto my list?

3.5 kW is perfect for simple point of use heating

The heating power may sound a little low compared to others on this list, but don’t let that fool you. The efficiency and the storage volume also need to be factored into such judgments, and I encountered no issues during testing. It’s got all the makings of an efficient addition to your home that will make life that little bit easier.

Allows you to save up to 60% on your water heating costs

I love how efficient this thing is, and for me, the proof is always, in those monthly bills. I took a look at mine, and it did actually come very close to the maximum advertised saving of 60%. And have in mind that that’s without any specific optimization on my part. The fact that I got so close to such an impressive figure with no concerted effort to achieve it on my part is a testament to the efficient design. Well done in that respect guys!

A very impressive 99.8% energy efficiency rating thanks to self-modulation technology

I love that the self-modulation works in the background without you even realizing it. If you use an old style heater, then you’ll notice that it cuts on and off quite dramatically. The problem with this is that it’s basically luck whether you have a hot tank of water or a cold tank of water waiting for you. This unit does things a little differently by intelligently regulating its internal temperature. In my opinion, the results really did speak for themselves!

5. Stiebel Eltron Tempra Plus 29 kW


This is a name that anyone who’s knowledgable about home appliances will be familiar with. I couldn’t wait to see what they bring to the table so without further ado here’s how their offering per-formed…

Works for variable flow rates which is a very nice little feature

I love that this thing actually smooths out the interruption caused by variable flow rates. It helps make life that little bit easier and removes an annoying problem the moment you install it.

29 kW of heating power is undoubtedly competitive on this list

The heating power of this thing is pretty immense if you ask me. And the great thing is that its super efficient too which means you’ll never have to wait again for your hot water to kick in. I found it super easy to control the final temperature, and I think you’ll have all the fine control you need.

Self-modulating functionality is great, at saving you money on those monthly bills

We all have one eye on our monthly bills, don’t we? There’s nothing more annoying than thinking you have a solution only to find out it costs way more than your budget allows. I was delighted with the impact the self-modulating technology had on my monthly bill. It dropped almost in half which was a nice little bonus, to say the least.

Doesn’t require venting which means you can reduce your monthly maintenance schedule

I like that this thing doesn’t need manual venting to remove excess pressure. That is great because it means that you can cross another time-consuming job off of your monthly maintenance list. It also means the unit is safe and essentially an install, and forget piece of kit that will work fine for years to come. Well thought out design that comes highly recommended by yours truly.

Best Electric Mini-Tank Water Heaters

6. Bosch Tronic 3000 T 2.5-Gallon Electric Mini-Tank Water Heater

blank
No list of home appliances would be complete without a product from these German giants. Here’s how their latest offering got on…

2.5-gallon mini tank is great for use in the kitchen

I like the idea of fitting the mini tank under the kitchen sink. By keeping your tank close to the point of use, you’ll be able to make things so much easier. Perfect if you want to be able to pour hot water for a brew instantly. The mounting system is also really, easy to work with which is ideal if you want a flexible installation.

Glass-lined tank increases the lifetime without reducing the heating capability

I like the glass-lining approach because it prevents the water from corroding the inside of your tank. That is ideal for not only extending the product lifetime but also maintaining the purity of the water supply. I experienced no issues with the optimal heating settings, and it worked just like a standard tank in that respect. A tremendous little innovation if you ask me, my friends!

Can be connected to two sinks at the same time to make life easier for you

Another thing that I was a big fan of is that you can connect it to two sinks. That gives you added flexibility, especially in larger family kitchens. For me, these devices are all about making your life easier, so it’s worth opting for these additional features. Even if you don’t use it now, you’ll have the peace of mind that your new device is future-proofed with expansion in mind.

Accepts any style of cold water line during installation

The installation of this piece of kit was super easy because it accepted the cold waterline without any hassle which was great. I didn’t need any special tools which, was ideal because it allowed even a novice to install it. If all you want is something that works straight out of the box, then this could be just what you’re looking for folks. And take it from me, you won’t have to rummage through the garage for an old adaptor ever again!

7. Rosewill Electric Hot Water Boiler and Warmer


Rounding of my list of 7 of the best is this entry from Rosewill. They’ve been in the game for a long time so I had no qualms about taking a look at their latest product.

4 Liter capacity makes this ideal for use in the kitchen of every coffee lover

The capacity of this thing is all about convenience. It’s never going to be enough to run a bath with, and that’s not at all what it’s been designed to do. It’s all about making your life easy in the kitchen so that you can get a hot drink on tap. Perfect for those of you who love a coffee first thing in the morning but don’t want to have to wait for the kettle.

Blue light water gauge makes checking the level, instantaneous

I like how the light gauge, adds just the right blend of style and substance to the design. By being able to check the water level with a quick glance from across the room, you’ll know precisely when it could do with a top up. Perfect for making sure that’s another of those little jobs that can eat up your day taken care of.

Dry boiling protection will definitely extend the lifetime of your unit

This is something that’s important as it’s a fundamental safety feature. Why? Because it cuts out when it is empty, you won’t run the risk of electrical fire. Ideal for sleeping with the peace of mind that you have everything take care of. Every device should come with this type of cut out feature as standard but take the time to check just in case.

I was a big fan of the stylish stainless steel outer casing, I think you will be too!

I love the stainless steel casing on this thing because it looks great in any style of kitchen. Remember with a countertop option like this you’re going to have it on show all day long. Take the time to pick something that looks as good as this, and you won’t go far wrong folks!
