    • Excellent Value — Compact, Powerful, and Reliable
Style: 14L-Natural Gas
I bought this 14L natural gas tankless water heater for my small condo and it has exceeded expectations. Installation was straightforward for my licensed plumber (unit is compact and lightweight for indoor mounting). The digital Fahrenheit display is clear and accurate, and setting the desired temperature is simple. On-demand hot water kicks in almost instantly and it comfortably handles one shower and a sink at the same time — I measured about 3.5 GPM when both were running. The unit fires up quickly and maintains temperature well even under moderate flow. ... show more

    • Endless Hot Water & Great Value!
Style: 14L-Natural Gas
I couldn’t be happier with the Nessxa 14L Natural Gas Tankless Water Heater. The installation was straightforward for a professional, and once it was set up, the difference was night and day compared to my old tank system. The hot water is truly instant no more waiting around or running water down the drain. The digital display is clear and easy to use, and I love being able to switch between Fahrenheit and Celsius. The safety features, like the automatic overheat protection and gas leak detection, give me real peace of mind. With its solid build quality, powerful output, and efficient performance, this unit easily handles multiple fixtures in my home without losing water pressure. At this price point, it’s an amazing deal for the performance it delivers. Highly recommend to anyone looking for a reliable, long-lasting, and energy-saving upgrade! ... show more

    • Absolute Nightmare of a Tankless Water Heater
Style: 14L-Natural Gas
This is, without question, the worst natural gas tankless water heater I’ve ever owned. From the moment it was installed, it’s been nothing but problems. The unit constantly shuts off mid-shower, throws random error codes, and takes forever to heat up — which defeats the entire purpose of a “tankless” system. Half the time I’m standing there freezing, waiting for the thing to decide if it wants to work. ... show more

    • Compact and Powerful
Style: 14L-Natural Gas
This unit is surprisingly small but very powerful. It fits perfectly in my small apartment. The water gets hot within seconds of turning the tap on. It looks modern and sleek on the wall. The digital display is a nice touch for monitoring the temperature.

Style: 14L-Natural Gas
This 14L tankless heater is incredibly efficient and provides endless hot water instantly. The digital display makes temperature adjustments a breeze. Installation was straightforward, and the 3.7GPM flow rate perfectly handles two showers running simultaneously. Highly recommended for upgrading your home! ... show more

    • Propane Tankless Water Heater
Style: 14L-Natural Gas
Because it is designed to heat on demand, there is no need to store water in advance, and hot water is available almost immediately. It is very efficient and saves energy. The digital display is intuitive and clear, and you can see the water temperature and operating status in real time. It is easy to adjust, and the dark space gray appearance is also very modern. It can be installed indoors, and it is not large in size and will not take up too much space. The small disadvantage is that the installation requires gas pipelines and exhaust systems, which requires a high level of hands-on ability. It is best to ask a professional to install it. ... show more

    • good quality and affordable price
Style: 14L-Natural Gas
I'm very satisfied with this water heater. The installation process was quite easy, and the unit worked well from the first time I used it. Hot water comes out quickly and the temperature is stable thanks to the digital Fahrenheit display, which is very helpful for setting. The 14-liter capacity is more than enough for daily bathing needs. The design is also modern and space-saving because it's tankless. It's energy-efficient, practical, and very convenient to use. I highly recommend it for any household. ... show more
