The Stiebel Eltron Tempra 24 Plus is a tankless electric water heater designed to provide on-demand hot water without the drawbacks of traditional storage heaters. One of its standout features is the Advanced Flow Control technology, which maintains a steady water temperature, ensuring that showers or hot water tasks can be completed without interruption. This makes it highly suitable for households where multiple hot water needs are common.
In terms of size, its compact design allows for easy installation in various spaces, making it a great choice for homes with limited installation areas. The unit's energy efficiency is another strong point; it uses auto-modulation to save energy and even includes a savings monitor to track energy costs, appealing to environmentally-conscious users and those looking to reduce utility bills.
The Tempra 24 Plus also offers user-friendly operation with digital temperature controls and presets, making it easy for anyone to set their desired hot water temperature. With a decent warranty of 7 years for leaks and 3 years for parts, customers can expect reliable long-term performance. There are some considerations to keep in mind. The heater requires a minimum recommended electric service of 150 amps, which may necessitate electrical upgrades in older homes. Additionally, while it can provide hot water continuously, its maximum temperature limit of 140°F might not be sufficient for all users, especially in areas with colder climates or higher hot water demands. The Stiebel Eltron Tempra 24 Plus is an excellent choice for those seeking an efficient, space-saving solution for hot water but may require additional considerations for installation and service requirements.
The Ranein Electric Tankless Water Heater is a compact and energy-efficient option for those wanting on-demand hot water without the wait or energy loss of traditional tank heaters. With 18 kW power and a flow rate of up to 4.3 gallons per minute, it's suitable for 2 to 3 water outlets, making it a good fit for smaller households or moderate hot water use. Its high thermal efficiency of 99% means it wastes very little energy, potentially cutting heating costs by up to 60%. The LED temperature display and simple knob controls make it easy to set your preferred water temperature precisely, ranging from 86°F to 131°F. The unit’s small size (about 14 by 19 inches) allows flexible installation, saving space compared to bulky tanks.
Safety is well-covered with multiple protections against leaks, overheating, and moisture, giving added peace of mind. However, it requires a 240-volt power supply with a double 40-amp circuit breaker, which may need an electrical upgrade in some homes. While it delivers endless hot water, the flow rate might be limiting if you have a larger household with higher simultaneous hot water needs. This heater is ideal for users looking for a space-saving, energy-efficient, and easy-to-use tankless option for moderate water demand, but those with larger households or very high usage might need a more powerful system.
The BOSCH Electric Mini-Tank Water Heater Tronic 3000 T 4-Gallon offers a compact and efficient solution for immediate hot water needs. With a 4-gallon capacity, it's ideal for small spaces like under-sink installations. Its 98% thermal efficiency ensures minimal energy waste, making it a cost-effective choice. The heater’s fast recovery rate is beneficial, providing quick access to hot water, and can supply up to two sinks simultaneously.
Installation is flexible and straightforward with options for shelf, wall, or floor mounting, and the unit plugs into a standard 120-volt outlet, avoiding complex electrical work. The heater’s glass-lined interior is designed for longevity, though regular maintenance of the anode rod is crucial to prevent leaks and maintain its durability. It’s important to note that neglecting this maintenance can void the warranty.
Bosch provides a 6-year coverage on the unit and 2 years on parts, which offers some peace of mind but requires attention to upkeep. In terms of size, the heater is compact with dimensions of 13.75 x 13.75 x 13.5 inches, fitting neatly in tight spaces, but potential users must ensure they have sufficient room for installation. Safety-wise, the heater supports a maximum pressure of 150 PSI and a maximum temperature of 140°F, suitable for typical household needs. This unit is ideal for individuals seeking an on-demand, space-saving hot water solution with low energy usage, though it may not be suitable for larger households or situations requiring higher flow rates or capacities. As a point-of-use heater, it's best suited for specific application areas rather than whole-home water heating needs.
