What Is Interesting About the Stiebel Eltron Tempra 29 plus?

Same temperature despite the change in flow

In the case of tankless water heaters, the temperature can vary as the flow rate varies. This can cause distorted situation especially if you are I middle of a bath. Stiebel Eltron realized this problem and introduced Tempra Advanced Flow Control technology. If water is freezing and comes with greater flow Tempra flow control reduces the flow to keep the temperature hot as selected even though the water pressure becomes low.

Endless hot water

Stiebel Eltron Tempra 29 plus Electric Tankless Water Heater has smart microprocessor technology in a Tempra® allows you to set the knob and get that temperature every time a hot water faucet is opened. Stiebel Eltron’s Electronic Temperature Control ensures a steady output temperature when the flow is uncontrolled, their smart microprocessor technology monitors the heat and maintain it endlessly.

Unlimited Supply of Hot Water

No venting required

I used to have an indoor gas-fired tankless water heater it was excellent, but I did not quite like the idea of gas emission through my home roof. Also setting the unit at a place maintaining side spaces safe for exhausting was quite tricky for my home size. Tempra Plus 29 kW is much better in that respect because it needs no venting. It is an all-electric water heater so you can install it anywhere without being troubled about the air pollution and venting space requirement.

Good looks

Tempra Plus 29 kW with 21.8 x 19.2 x 9 inches and 17.4 pounds has a narrow outlook. In comparison to the conventional water heater, it saves 12 cubic feet and can fit into any corner of your home.

Digital temperature control

Tempra® Plus models have convenient digital temperature control, offering a scale of 86°F (30°C) to shower temps of 107°F (42°C), up to 140°F (60°C) for commercial applications. Once you choose a temperature for the whole bath, you are guaranteed to get it until the end. However, if you chose high temperature more electric consumption will occur.

What People Do Not Like

Very bad with hard water condition

It can work at your home if you have water with PSI more than 150 and less than 300. Which is quite a high standard so do not bother to install it with PSI less than or beyond that range?

Solution

Water hardness is something responsible for many water fixtures to fail early. Test you PSI if your fixtures are failing, or you are having scruples whether your water quality is the villain. When your water hardness exceeds 7 grains per gallon (GPG) or 120 mg/l (ppm), it is called hard water and requires special treatment. Before you go for Stiebel Eltron Tempra 29 plus or any other water heater you should consider hard water treatment. Hard water causes premature failure of water fixtures owing to mineral build-up inside the heating module and other components. Also once your water is sorted water flow will be optimum, fixtures will run longer and complain free.

It functions poorly at the beginning

It does not give you hot water at the very beginning; you have to wait 10 seconds or more for the hot water.

Solution

It is a standard issue with Tankless units. A flow sensor senses the minimum flow and starts the heater burner. This has a right side a wrong side; right side is- It reduces your electricity cost than the conventional heaters by not being at a function when idle, demerit is it makes you wait 5-7 seconds at the beginning for hot water. If you can install a re-circulation pump from the market which cost much less than a heater than such waiting period will evaporate.
