The Stiebel Eltron Tempra 29 Trend Tankless Water Heater is an excellent choice for residential use, particularly for those looking for an efficient and space-saving solution. With a maximum flow rate of 9.5 gallons per minute, it can comfortably provide endless hot water for multiple showers or taps simultaneously, ensuring that your hot water supply is uninterrupted. This model operates quietly, which is a significant advantage for home environments where noise levels matter.
Energy efficiency is another strong point, as this unit utilizes auto-modulation technology to save energy when hot water isn’t needed, making it eco-friendly. Installation is straightforward since it doesn't require venting, but it does necessitate a minimum electric service of 200 amps, which could limit its compatibility in some homes that don't meet this requirement.
The digital temperature display adds convenience, allowing for easy monitoring and adjustment of the water temperature. In terms of longevity and reliability, Stiebel Eltron backs this product with a 7-year leakage warranty and a 3-year parts warranty, giving users peace of mind.
While the initial installation cost might be higher than traditional tank water heaters, and the requirement for a high electrical service can be a hurdle for some households, its compact design saves space. However, its reliance on electricity may not be ideal for everyone, especially in areas with frequent power outages.
This model is best suited for families or households with high hot water demands who value continuous supply and energy efficiency. If you’re looking for a reliable, quiet, and eco-friendly hot water solution, this Stiebel Eltron model delivers strong performance, but be mindful of your home's electrical capacity before purchasing.
The Rheem 18kW Tankless Electric Water Heater is a solid option for households seeking a reliable source of hot water. With a maximum flow rate of up to 4.4 gallons per minute (GPM), it’s suitable for smaller to medium-sized homes, providing enough hot water for multiple outlets at once. The unit boasts a remarkable energy efficiency rating of 99.8%, which can translate to lower electricity bills over time, making it an eco-friendly choice as well.
One of its standout features is the external digital thermostatic control with an LED display, allowing precise temperature adjustments (+/- 1 degree accuracy). This self-modulating technology helps it adjust power usage based on real-time hot water demand, giving you consistent comfort.
Installation is generally straightforward, thanks to its bottom 3/4-inch NPT water connections and wall-mount design. This means you can install it in various locations without too much hassle. However, it may still require a professional for optimal setup, especially if you’re not handy with plumbing. While it performs well in terms of flow rate and efficiency, some users might find the performance insufficient for larger households where simultaneous use of multiple hot water sources is common. Additionally, the unit's reliance on electricity means it won't function during power outages, which could be a concern in areas prone to such interruptions.
