Stiebel Eltron Tempra 24 plus Electric Tankless Water Heater

Features

Hot water always

In case of tank less water heaters, some features determine how efficient they are. Relation between heating speed and flow of water (GPM) is one of them. In this respect stiebel eltron tempra 24 plus has a consistent balance. At 1 GPM flow it gives 90 degree rise (minimum flow) while at GPM of 8 it gives 20 degree rise 0 volt at 240. At 208 this combination changes a little bit. Translating to our language it can support very high flow rate yet maintain hot water.

No more fluctuation

The manufacturer says it has the most modern technology that is microprocessor that does not let any fluctuation on water temperature despite high demand. Unlike many manufacturers I happen to trust this slogan as it comes from this very eminent German company whose heaters are valued worldwide.

No venting required

Gas fired tank less heaters are great for energy efficiency. Those are good if you’re electric configuration and wiring do not support an electric heater, but this stiebel eltron tempra 24 plus can beat them easily by saving the headache of proper venting. As it is electric you can hang it anywhere without concerning about the air pollution and venting space requirement.

Good looks

Most tankless water heaters have this feature, as they are not burdened with a big tank; they are quite compact. Stiebel eltron tempra 24 plus has a sleek look making it suitable to fit into the tiny nooks of your home or office.

Seismic Proof Construction

You need to go by seismic code preventive construction standards to install a Tank water heater. With Tempra no such preventive construction requirement is required.

Digital temperature control

It offers a scale of 30°C (86°F) and 60°C (140°F).You can choose between them and be sure that this will be the temperature till you further change it. One thing is to be reminded to cost conscious people that a high temperature will consume more electricity. Yet this wide range is offered because of different inlet water temperature and different type of usage.

Pros

  • Easy Installation.
  • Handles a high volume of water.
  • Compatible with 208/240 volt standard electrical wiring.
  • 3 year limited warranty when product installed by licensed personnel.
  • Warranty applicable for domestic and commercial usage.

Cons

Not enough for hard water condition

Stiebel Eltron makes water heaters for water condition with PSI 7 so it cannot support hard water.

Solution

To some extent Stiebel Eltron Tempra 24 plus Electric Tankless Water Heater can endure low ph or hard water, still if your water is too hard to handle you needs to give special importance to maintenance. So open and clear it with vinegar extract of what SE recommends for water composition not near to normal.

No alternative power resource

It does not have any option to work with natural gas or battery power.

Solution

Actually for off grade area this water heater does not works. So if you are living at such a place or a very eco person who believes in all natural and prefer gas based fixtures this is not a right choice.

Not good enough for really cold water

If the ground water is too cold the output will be only luke warm water

Solution

Stiebel tempra tankless water heater works when it detects a flow. So if the ground water is very cold for example 45 degree that does not mean the output will be luke warm. You can set high temperature (140 degree) on you heater and make sure the flow of water is more than minimum requirement to ignite the burner. What the technology does is it uses it’s flow limiter .When inlet water is very cold it will limit the flow rate in order to be able to keep up the temperature high and produce hot water.
