forimo Water Heaters Water Heater -022 Editorial Review
**** The 18L propane water heater has garnered a mixed reception among users, oscillating between appreciation for its design and performance, and frustration due to reliability issues. Many users find the heater effective for specific needs, such as heating water for showers or filling hot tubs efficiently and quickly. Notably, it can raise the temperature of a hot tub significantly in a short period, making it a preferred choice for those who seek affordability and efficiency in propane usage. Installation appears relatively easy for seasoned users, especially for those who have previously owned a similar model. The design, while simple, does come with some caveats, as some users reported mechanical and operational flaws right out of the box, including broken welds and non-standard fittings that complicated installation. Although described as user-friendly once set up, several reviews noted difficulties with the controls, indicating that they may not be intuitively labeled. Reliability is a notable concern. A few users report that the unit began to experience intermittent functioning or ceased operations entirely after minimal use. These reliability issues lead to significant dissatisfaction, particularly for users who expected longevity based on previous experiences. Additionally, the lack of responsive customer support has caused frustration, making warranty claims or troubleshooting a challenging task for some Consumers. In conclusion, while the heater is well-liked for its performance and ease of use once operational, potential buyers should weigh the risk of inConsistency and customer support challenges against its affordability and efficiency. **
