Stiebel Eltron Tempra 24 Plus tankless electric water heater Review

Compared to a conventional unit, an electric tankless water heater will typically gobble up 15-to-20% less energy. If you have a standard electric tank water heater, it ceaselessly holds hot water and subsequently dissipates 15-20% of the overall power they eat up to the surroundings.

Gas and oil tank water heaters render far much less efficiency given that you have to vent them outdoors. Examine our in-depth Stiebel Eltron Tempra 24 Plus tankless electric water heater Review-the unit works vent-free without retaining full temperature boiling water.

Install low-flow showerheads and flow-resistant sink aerators; maximize household water usage patterns to cut back thousands of bucks.   

A. Exclusive & Advanced Flow Control Technology 

Tempra Plus tankless electric water heater comes with branded Advanced Flow Control™ that maintains a constant temperature. If the consumption of hot water surpasses capacity, Advanced Flow Control™ offsets flow insignificantly to retain a consistent heat.

Spawned by Stiebel Eltron, the invention ensures a constant temperature level by automatically tweaking the stream of water without disruptive temperature fluctuation. The feature comes in handy if you dwell in cold climate zones and other appliances where the electrical service size negates the integration of a super-massive model.

The Tempra Plus tankless electric water heater meets infrequent high flow needs. It’s also more efficient for applications that consume high output temperatures. Especially in commercial dishwashers or operations with variable flow rates.             

B. Microprocessor-Controlled Temperature 

Tempra 24 Plus boasts Stiebel Eltron's original microprocessor-controlled temperature parameters with a handy digital temperature display. A dashboard on the front of the machine allows you to adjust the output temperature from 30°C to 60°C.

Temperature and flow sensors transmit troves of data to the microprocessor continuously for the system to maintain the pre-determined output water temperature. Tempra 24 Plus innovative microprocessor technology promotes a steady output temperature whether flow rates increase or decrease.

 It’s a flagpole feature keeping Tempra 24 Plus streets ahead of the competition. Rival tankless electric water heaters cannot maintain a steady temperature against incoming flow instability.         

C. Unrestricted Flow of Hot Water 

The Tempra 24 Plus corresponds directly to your need for hot water without disruption. The patented Electronic Temperature Control allows adjusting the knob on the front lid to the water temperature demanded and getting that output every time you open a hot water tap.

Your shower squirts hot water, even if it bathes in a row and also lasts long. A tank water heater can deliver volumes at once, but if the unit starts to fritter away to frigid temperatures fast, it takes longer to resuscitate.

You will save plethora bucks with 99% energy efficiency and intelligent self-modulating technology that ensures less electricity consumption.     

D. Sturdy, Durable & Seismic-Proof Construction 

The entire Stiebel Eltron Tempra product line features a sturdy steel housing with integrated wall mounting brackets. A vast majority of competitors use light-gauge plastics and aluminum. The unit comes encased in a handy hinged covering for easy access.

Crafted in a sleek design, you will save scores of square feet of interior space that a mammoth tank encroaches. Its seismic-proof constructed and not subject to the building code as a tank-less water heating system. It does not require preventative construction like a tank water heater.

The Tempra 24 Plus does not possess any mechanical switches and renders a super-quiet operation.   

E. Easily Installable

Given its compact design, you’ll install the appliance at the drop of a hat. Storing water at an extremely high temperature in a conventional unit lessens its lifespan; the Tempra 24 Plus offers prolonged service life, saving hundreds of bucks with minimal replacements.

Massive and bulky hot water tanks mainly stay in a basements and utility rooms. The container ends up several yards away from where hot water comes out of the tap causing delayed heating.

You can ensconce the Tempra 24 Plus in proximity to the warm water tap. It reduces the delay for hot water supply within the shortest space of time.

Why should you use Stiebel Eltron Tempra 24 Plus tankless electric water heater? 

Superior Performance and More Efficiency 

The Stiebel Eltron Tempra 24 Plus high-performance permits a broad range of applications. The 24KW heater delivers unlimited hot water for a full house, apartment or commercial premise. It’s the most excellent option if you receive water under 45F. The unit packs power to deliver five gallons per minute making it suitable if you want higher water flow rates.

Digital Temperature Control Panel 

You can immerse yourself in the Jacuzzi and Roman-style tubs by tweaking the power from a minimum of 18kW to 24kW. The digital temperature control panel allows you to adjust output temperature from 86-to-140F. It also offers a dual heating module that can increase the water temperature in 54F at 3GPM.  

Advanced Flow Control Technology

The heater system features the rare Advanced Flow Control technology. Thus, it attunes the water flow rate if the sensors identify excessive use of hot water. The Stiebel Eltron Tempra 24 Plus temperature and flow sensors feed their data into the unit’s patented microprocessor control. It unremittingly regulates incoming water temperature and the output it generates. It utilizes its heating sources in stages to attain your preferred water temperature with more efficiency.

Convenient Water Supply 

The unit works with different kinds of water such as well-pumped, hard and soft, as well as city. Thus, you can install it on the commercial or residential property. It’s mainly useful for users in areas with occasional demands for high hot water flow speeds. You can restrict the maximum output temperature at 109°F for installations that require protection against scalding.    

Slashes Off 60% of Conventional Electric Water Heaters 

Unlike conventional units, tankless water heaters can inhibit standby heat losses associated and cut back energy bills significantly. You’ll tighten the purse strings in the long run. If your household consumes 41 gallons or below of hot water per day, tankless water heaters render 24%-34% more energy efficient than outgoing models.
