The Bosch 940 ES NG Tankless Water heater is designed specifically for safe indoor use. However, getting the right venting kit allows you to install it in an outdoor environment as well. We at TopTenWater.com have discovered that it has a long-lasting heat exchanger which generates a high energy factor of 0.83, which is more than enough for it to qualify as Energy Star compliant. Its flow rate of 9.4 Gallons Per Minute makes it an ideal solution for families that require the use of up to 4 showers simultaneously.
It has a minimum water flow of 3 GPM, which also makes it suitable for situations where one would require a smaller amount of hot water. If waiting for water reserves to warm up is not exactly your cup of tea, you can pair the tankless unit with the storage tank and Ariston mini-tank Tronic, which should reduce the waiting time. For larger households that require additional hot water, you can install up to 24 units, which should generate more than enough hot water for your needs. If you require even more, you always have the option of combining it with the solar water heater system.
Depending on how much power is needed, the unity adjusts automatically (from 19,900 to 199,000 BTU). Furthermore, we have found the LCD display to come in handy for diagnostic purposes, allowing you to quickly identify what’s wrong and repair it. All in all, when compared to other models you can get from Bosch, this model produces higher water flow. It runs on natural gas or liquid propane, its compact design allows you to place it practically anywhere you’d like, and it’s suitable for use in offices, homes, or even outdoor environments.
To sum it up:
- Compact and easy to install
- Integrated LCD screen makes troubleshooting easy
- 15-year warranty and 20 years of expected lifespan
- Automatically adjusts power consumption based on what’s needed
