There was a time when products seem to appear to answer our needs; a time when the solution comes after the dilemma. Now, not only do new products appear fast, they also become somewhat of a necessity and a part of our daily lives and habits.
Our lifestyle no longer dictates what we want or need. Now, the presence of new and seemingly important applications of new technology is the thing that dictates what our lifestyle should be.
There was a time when we were woken up, not just by our morning coffee, but by our cold morning baths; there was a time when we could take the cold, but with the presence of water heaters and hot baths why should we?
Then here came another innovation in hot water supply, the electric tankless water heaters.
Back then, hot water was not readily available at all times, you can even say it was a luxury available only to the few who could afford to have it.
But change happens fast in a society constantly looking for needs to meet, resulting in hot water on demand and around the clock, being available to almost anyone who has a home, and that is through the use of an electric tankless water heater.
How to choose your electric tankless water heater
First, as in all things, you should ask yourself what your needs are when it comes to hot water on demand. Do you need hot water in your bathrooms? How many baths or shower do you have? Do you need hot water in the kitchen? Do you need hot water for the entire house? Do you need hot water simultaneously in different parts of the house?
This all comes down to determining the capacity of the electric water heater you need. The capacity is measured by the rate at which water flows through the heater and still produce hot water in the process. Flow rates are commonly measured in gallons per minute, or GPM.
The next steps are relatively easy; you just have to choose the brand you think is worth buying over another. You should choose the brand that will work well with the temperature of the water in your place. Some water heaters only work well in places within moderate to warm climates.
Ask around; do not just ask the manufacturer or anyone who will be biased in favor of the product. It is better to read reviews from actual customers who have used the unit.
You should also think about the cost you will have to incur in installing the electric tankless water heater; plumbing and electrical installations will be required from a professional in case you are installing a whole-house electric tankless water heater.
Here are some of the available electric water heaters in the market.
Lotus 3.5kW/120V Electric Tankless Water Heater
One of the most notable attributes of the Lotus 3.5kW/120V Electric Tankless Water Heater is its compact size, which makes this heater good for those who live in a small environment. Its eco-friendly attributes will provide hot water if you don’t need much.
- Tankless and gives you unlimited hot water when you need it
- Single-sink application design
- Works best in moderate to warm climates
- Optimum water flow of 0.5 gallons per minute
- Energy efficient and helps you save up to 50% of water heating costs
- Compact design
The Lotus 3.5kW/120V Electric Tankless Water Heater is a small compact electric tankless water heater and it will fit very well in your bathroom or under the sink. It is also a very good fit for those who are living in small condos, apartments or small one-bedroom houses. It also promises to be energy efficient and to help you up to 50% of your water heating costs.
However, it is not suitable for those who need hot water simultaneously in two different parts of the house. This electric tankless water heater has a quite limited capacity and can only function well at a rate of 0.5 gallons per minute.
It will also be effective only in places with warm or moderate climates. Any lower than that and you will find it hard to squeeze hot water from this unit.
Accordingly, the Lotus 3.5kW/120V Electric Tankless Water Heater can be utterly useless in places with snow, which is ironic because it is in such places that people often need hot water. And because of its limited heating capacity, you would have to suppress or control the water flow from your faucet, and for that, you will need an aerator.
The Lotus 3.5kW/120V Electric Tankless Water Heater, despite having a very limited capacity, is not a total disappointment. Its size and eco-friendly, energy saving attributes can still supply hot water to those who are not really in need of that much. It is certainly the way to go for small-range or low-capacity use, and for homes located in warmer climates.
However, it is too small for households that want hot water running in both their sinks and showers. Further, nothing will prevent people from buying a higher capacity electric tankless water heater and adjusting it to low.
That, in a way, makes a low-capacity electric water heater like this one somewhat redundant. All in all, the Lotus 3.5kW/120V Electric Tankless Water Heater is gets a 5 out of 10.
Heat Wiz HWJ120T Tankless Water Heater Model, 11 kW
Some say that the Heat Wiz is the future of tankless, electric water heating. This electric tankless water heater combines portability, a compact design, efficiency, and the potential to replace your big water tank heaters. The Heat Wiz not only promises energy efficiency or power saving features, it also promises a much higher and less limited water heating capacity, despite being small.
This electric water heater has the following features:
- Advance patent heating technology which prevents heating loss, allowing you to save up to 50% on water heating cost
- Multi-layered heating chamber that forms a long circulating water channel
- LED touch display
- Compact design
- 10-year manufacturer warranty
- IMD front cover
- Automatic memory function avoids repeated operation
- Built-in over-pressure and over temperature protection
This electric tankless water heater is compact and small, but what makes it a very good choice for hot bath lovers is that it has the capacity of a much bigger water heater.
This electric tankless water heater with 240v has been known to heat up to three baths without compromising water temperature and performance. It can be cheaper to use as compared to the big water heater that you may already have at home.
It has a very stylish design and it is easy to operate with the help of its LED touch display. It also has an enclosed loop heating system which helps retain heat and add to the efficiency of the unit, and helps it to retain more heat. With its higher capacity as compared to other small, portable electric tankless water heaters, the HeatWiz has a better shot at working in places with cold climates.
But despite all of the good things about this electric tankless water heater, it still cannot be considered as a complete replacement to water heaters that are actually configured for the whole house. Some may have made the mistake of installing this electric tankless water heater for more than three showers plus sinks. That might result to a notion that the HeatWiz cannot live up to its promise, which is not necessarily true at all.
The capacity of this electric tankless water heater to heat two showers or baths, or two sinks at the same time, or a sink and a shower, despite being a small portable, makes this electric tankless water heater a good choice for those who are looking to have hot water and save space at the same time. It is a small heater that packs a punch. It deserves an 8 out of 10.

All of that makes this water heater a very good choice for smaller homes, commercial spaces, restaurants and other similar sized establishments needing hot water around the clock.
The Bosch WH17 Tronic 6000 C Electric Tankless Water Heater has been said to be difficult to install, and that decreases its cost effectiveness.

All in all, you might spend more than $1,000 before the water heater is put to use.
The Bosch WH17 Tronic 6000 C Electric Tankless Water Heater was also somewhat notorious for not being able to deliver on its name as a whole-house water heater, and that it is only good for serving one service area.
There is a good chance that the Bosch WH17 Tronic 6000 C Electric Tankless Water Heater would not be able to give hot water on demand if your house is located in a cold place because that would necessarily mean that the water from your water supply is much colder and difficult to heat.
Considering that the Bosch WH17 Tronic 6000 C Electric Tankless Water Heater was classed as a whole-house water heater, you would expect that it could easily supply hot water all around the house and not just in single service area without external factors having much effect on its performance. All in all, it receives a 6 out of 10.

However, this Rodwil Electric Tankless Water Heater is not an all-encompassing water heater with unlimited residential capacity.

The Rodwil Electric Tankless Water Heater Instant On-Demand has delivered on its promise as a good, reliable portable electric tankless water heater. All in all, it earns a 7 out of 10.
