MIZUDO Water Heaters Etech 40 | 4.0 Gallon Editorial Review
This small water heater has received generally positive reviews from customers, who are particularly impressed by its compact design, fast heating capabilities, and ease of installation. Users have noted that it takes roughly 45 minutes to reach its maximum temperature, but once it has, it delivers hot water almost instantaneously—some users reported hot water arriving at their kitchen sink in just two seconds. This rapid recovery of hot water has made it a favorite among those using it in RVs and small spaces. Installation is frequently highlighted as a straightforward process, with many customers praising the clarity of the installation guide, which helped them easily swap out a broken unit. The size of the heater is another positive point, as it fits snugly under sinks, making it an ideal choice for limited spaces. However, several reviews indicate concerns about a potential leak issue related to the front panel, which led to disappointment for at least one customer who could not return it due to storing it too long before installation. Another user expressed worry about the power cord getting warm near the outlet. Still, these issues do not seem to overshadow the overall satisfaction expressed by many users regarding the heater's performance and efficiency. Overall, the small water heater stands out as an affordable and effective choice for individuals seeking reliable hot water solutions without taking up too much space. ###
