Frankly speaking, I’ve been working as a smart home consultant for quite some time now, and during this tenure, I’ve seen the tankless brands bubble and their fast disappearing as well.

However, Eccotemp is the brand that was mentally prepared to be in the game for a long-time.

Needless to say, the brand has proved its mettle time and again.

I would suggest you should opt for the Eccotemp tankless heater that NOT ONLY syncs well with your requirement but also falls well within your budget.

Eccotemp Systems EL22i

The Eccotemp EL22i is the successor of the popular EL22 model of the brand that has garnered eyeballs because of its performance and efficiency.

What I actually mean is, if you would like to use EL22 then definitely, EL22i would be your next choice in case, you’re planning to upgrade your tankless heater.

Definitely, the look and feel of the EL22i resembles its predecessor, but at the same time, the upgraded version is equipped with a bunch of new and advanced features.

The unit could be a great fit for the first-time buyer as it is a fully automated water heater that has enhanced performance and efficiency as compared to its predecessor.

The all-black svelte glass casing and the large digital temperature display give the unit a premium look that can sync well with your home decor as well.

The advanced and innovative technology that the unit is equipped with makes it possible to regulate the heating temperature automatically depending upon the temperature of the incoming groundwater.

And, as a result, the heating bills decrease drastically.

With a rating of 140,000 BTU per hour and a maximum flow rate of 6.8 GPM, the unit is bound to deliver high-performance effortlessly.

The unit could be a great choice for a 2 BHK apartment with 2 bathrooms.

Moreover, the touchscreen control panel adds convenience and enhances the user experience multiple-fold.

The CSA-certified heater also comes with an integrated anti-freeze circuit that ensures that any remaining water in the plumbing doesn’t freeze if the temperature drops.

The EL22-I is a gaseous tankless water heater that uses either liquid propane or natural gas as fuel.

It is equipped with safety features including a child lock that once activated instantly looks at the touchscreen control panel so you don’t have to worry at all for your kids and pets.

However, you’ve to buy SEPARATELY 4” venting for the power circuit.

Lastly, the EL22-I is backed by 10 years warranty on the heat exchangers and 5 years on parts which clearly depicts the confidence and trust of the manufacturer in its offering.


  • Small, compact, and sleek designed indoor tankless water heater

Eccotemp N45HI-NG

So, here I come with my favorite pick from the brand Eccotemp.

Many of you wouldn’t be aware of the fact that N45HI-NG is the largest indoor tankless water heater model that the brand is offering right now.

Unlike the aforementioned model, the N45HI-NG will give you a feeling of simplicity and easy-going.

The control panel is also simple and comprises a bunch of push-button.

With a 140,000 BTU rating and a maximum flow rate of 6.8 GPM, the unit is bound to deliver high-performance effortlessly.

In layman’s terms, the unit is powerful and will heat the water quickly.

In fact, it can serve you well in cold climatic conditions as well.

The N45HI-NG successfully handles the temperature fluctuations and so you’ll not have to bear cold water in the mid of your shower.

And, the best part is, the unit comprises an automatic temperature control system that ranges from 90 to 140 degrees Fahrenheit.

The N45HI-NG will perform uninterrupted even in the cold climatic condition, and the credit goes with the anti-freeze circuit that the unit comprises.

However, the thing that I really don’t like about this unit is the lack of child lock which may offend many parents like me.

The only solution I find to deal with the issue is to use a vanity counter.

Of course, the installation process is newbie-friendly and wouldn’t consume much of your time.

And, if you’ve got prior plumbing experience, then you can install the unit on your own, and thanks to the detailed instructions that the unit comes with.

Furthermore, the N45HI has an energy factor (EF) rating of 0.80 which is excellent with an extremely high recovery rate of 82%.

Since the unit is tankless so there isn’t any standby heat loss to the environment which results in reduced annual operating costs.

And, like the aforementioned model, the N45HI is also backed by a 10-year warranty on the heat exchangers and a 5-year warranty on the parts.


  • The small, compact, and sleek design makes the unit highly suitable for indoor uses
  • Automatic temperature control
  • Anti-freeze circuit
  • EF rating of 0.80
  • 82 percent recovery rate
  • Can save you up to 40 percent on your gas bills
  • 140,000 BTU
  • 6.8 GPM flow rate
  • Manual, push-button control panel


  • No child lock feature

Eccotemp L10

The Eccotemp L10 is a unique blend of small size and high-performance.

Irrespective of being small-sized, the unit doesn’t compromise on its efficiency or performance.

The N45HI comes with a white external casing and has two knobs associated with it.

The first knob is used to regulate the inflow of gas and the second one to control the temperature.

It also gives you the flexibility to manually adjust the temperature from 80 degrees to 140 degrees Fahrenheit.

You can install L10 outside your home and can be a great fit for off-grid since it comes with a battery igniter and a CSA regulator for attaching it to any 20 lbs grill propane tank.

You can also hardwire it to an LPG tank for a more permanent setup.

Frankly speaking, the flow rate of the unit is not something to brag about.

With a maximum flow rate of 2.65 GPM, the unit would be perfect for your RV or a small cabin.

The model handles the fluctuation of hot water in an effective way.

Furthermore, the L10 can run for up to 18 hours on a standard 20 lbs. propane tank.

Overall, the unit is versatile, cost-efficient, and performance-driven.


  • Compact unit for outdoor installation
  • Manual temperature control from 80°-140°F

  • CSA regulator for attaching to a 20 lbs. propane tank
