What Is Interesting About Stiebel Eltron Tempra 36 plus?

Big need checked

Places where the temperature drops up to 40 degrees or more, this Stiebel Eltron Tempra 36 plus can produce 3.9 Gallon per minute with a 105-degree Fahrenheit output. A standard shower with 1-2.5 GPM can work with a standard wash basin 0.5 -1GPM flow also it can support another kitchen sink with 1-2 GPM. In a warmer climate, Stiebel Eltron Tempra 36 plus can gives consistent temperature water to 3-4 bathrooms, or in cold climates, it can support 2-3 showers. However, that is the stories of maximum demand when there is an occasion or a party at home and live in guests are there to test the gravity of your fixtures by over usage. In standard scenario hardly you need more than two showers to work at the same time or 5 water fixtures to work at a time with hot water. So based on your regular demand you can choose this heater in colder place for a bigger home too. By the way, highest capacity is 7.03 gal (US)/min for 35 F Rise (gallons/min)

Temperature consistency in a change in flow

Tankless water heaters usually are unable to deal with the flow rate fluctuation, causing different temperature at varied flow rates. This causes dissatisfaction situation especially if you are taking a bath and experiencing it quite frequently. Stiebel Eltron had this epiphany and introduced Tempra Advanced Flow Control technology. This technology is capable of reducing the flow, if water is icy and comes with higher current, thus keep the temperature hot as selected. This can cause the pressure to get low, but the heat will not change.

Hot water till the end

Stiebel Eltron Tempra 36plus Electric Tankless Water Heater has a smart microprocessor technology this common in all the heaters of Tempra® series. It allows you to set the knob of temperature and get that temperature till the end. Stiebel Eltron’s Electronic Temperature Control will maintain a steady temperature of output even when the flow is out of control; their smart microprocessor technology will supervise the heat and preserve it eternally.

Zero venting required

Indoor gas-fired tankless water heaters are great things- they are energy efficient, eco-friendly, capable of heating water faster than electric ones. Still, they can easily be downsized by the fact that they need pretty restricted placement situation. Not a big issue for big homeowners, but for small homes maintaining side spaces for safe exhausting is quite tricky. Maybe that is why most of these are designed for outdoors. For Stiebel Eltron, Tempra 36 plus such restrictions are not a thing to ponder on, because it needs no venting. It is an all-electric water heater; you can install it, wall mounts it anywhere without being troubled by venting space requirement.

Good looks

Stiebel Eltron Tempra 36 plus with  21.5 x 19.5 x 9.5 inches and 17.6 pounds has a Sleek design that fits anywhere, In comparing to conventional water heater it saves a lot of  11 +cubic feet, and it looks great. Now it is up to you whether you want to hide it or flaunt it.

Digital temperature control

Tempra® Plus models have a digital temperature control system; it offers a scale of 86°F (30°C) to shower temps of 107°F (42°C), up to 140°F (60°C) for commercial applications. I am sure most of you already know it still it is an important thing to share that- If you chose high-temperature electric consumption will be more.

What People Like

  • Overheat Protection
  • Straightforward & self-attainable Installation
  • Works with both 208/240 volt standard electrical wiring.
  • Three-year limited warranty for both domestic and commercial usage on parts and 7 Year on the heat exchanger.
  • It is ETL Listed (US & Canada), so it meets all applicable standards concomitant with ANSI/UL 499 (USA) and CSA-E335-1/3E-94 (Canada)

What People Do Not Like

  • It does not work with 200 amps- It needs 150 amps when at maximum point and startup, But with many 200 amp service wire, it is not usable.

Solution- I does not recommend someone to change the wiring of the house for installing a water heater. What is more comfortable is to figure out your house’s wiring service capacity. If your home has at least 300 amp wiring service, you can go for this unit.

  • 7 GPM is not achievable everywhere-The highest capacity of 7 GPM is obtainable only at places like southern Florida & Texas where water is already hot enough, and water heater will need to add just a little more heat to get the water up to temperature.

Solution- Manufacturer gave a specification sheet stating in what inlet temperature what GPM is expected. If you want 7 GPM at Maine or North Dakota in winter, I would recommend you to buy two of this unit or go for another more powerful. This is good at that temperature to give 3 GPM highest which is suitable for a shower at a time. This is not a real con it is just a disclosure.

  • Sometimes it fails to keep it hot - Some users complain endless hot water is not maintained in the long run.

Solution - Endless hot water is achievable if your water lines are clear and blockage free. So if you face such problem call the plumber or tech support and flush the water lines to remove any gunk/blockage, this will surely solve the problem.
