Stiebel Eltron Tempra 24 Plus 224199 Tankless Water HeaterComing home after a long day of work only to find there is no hot water left can be pretty frustrating. What’s worse is the electric bill you have to pay, in order to not have the hot water you need, when you need it. This is why many people in Asia and Europe opt in for an on-demand water heater instead of a traditional tanked one.

The people at Stiebel Eltron have been making electric tankless water heaters for years, and have become an industry favorite. We picked out, and tested, one of their bigger models for our Stiebel Eltron Tempra 24 Plus review. Before you decide whether this is the right choice for you or not, we wanted to supply you with all of the relevant information you could possibly need in order to make a decision.

In our review, you will find useful info like application, how much hot water the unit can actually deliver, and more.

Stiebel Eltron Tempra 24 Plus Specifications

Sizing is always an important issue that needs to be addressed when choosing a tankless water heater. How effective this electric on-demand water heater can depend on several factors, with the first one being power usage. This model uses 24kW at 240V and requires 2 circuits in your control panel, both at 50 amps.

With a 100-amp electric power draw, you can get solid performance even in medium climates. The application of this unit can vary, depending on the climate where you live. If the water you usually use is around 80°F (26.6°C), this water heater can produce a flow rate of up to 4.68 GPM/17.72 LPM.

With that much flow, you could cover 2 bathrooms simultaneously. In a smaller home with a kitchen and bathroom, this unit could be considered a whole-house water heater. But in a colder climate, where your tap water is about 60°F (15.5°C), you would only get 2.54 GPM/9.61 LPM. That is considerably less but still viable as a point-of-use machine.

You do need a 150-amp electrical service (at minimum) to use this unit, but even with that demand it still saves on the energy bill. Thanks to the heating elements and self-modulating technology, this unit have an energy efficiency rating of 99%.

What to Expect from Stiebel Eltron Tempra 24 Plus?

What it basically comes down to is water temperature and flow rate. Warm climates are excellent for this continuous water heater because it has to work less to provide you with running hot water. This unit could easily support an average household.

But, if you happen to live in a colder area, the unit must work harder and will produce a lower flow rate. As electric tankless water heaters shine the most as point-of-use appliances, this water heater is still a viable option in cold climates.

Installation is pretty straightforward if you’ve done electrical and plumbing work before. There isn’t that much maintenance involved with these machines. And if you use low-flow fixtures with this type of water heater, you will definitely notice the savings in your utility bills.

Pros

  • Has a 99% energy efficiency rating
  • Elements inside of the unit are made from materials that are corrosion resistant
  • Has advanced flow control for better flow regulation
  • Detailed user manual

Cons

  • Parts come with a 3-year warranty only
  • Older homes will have issues supporting the power draw of this unit
  • It isn’t recommended for cold climates

Wrap Up

While this model is not budget-friendly, you can get a lot of performance out of it in the right circumstances. You would need to live in a moderate to warm climate, low-flow fixture, and an average-size home. If that ticks all of the boxes on your list, then you may have found what you’ve been looking for.

But your situation may be different from what we have listed, so you may need a more powerful model. We hope that we have at least helped you narrow down the choices with our Stiebel Eltron Tempra 24 Plus review.
