Tankless Water Heater – Tempra 24 Plus – Electric, 24kW, On Demand Hot Water, Eco, White, Made in Germany

We love our water heater. Just finished our new home and moved in. 5 days now of showers and the heater works instantaneously just as advertised. I did my own plumbing and electrical so we handled everything required for our unit. Ours has 2 heating elements so we ran 2 each of 6-2w ground on 50 amp breakers to the unit. Instructions were clear and concise. We talked to a supply house that sells this brand as well as my brother-in-law plumber who uses these. They have never had a call back on this brand. Another aspect I love is that the electric bill stops as soon as you shut the faucet off. There isn’t a continuous heating of a tank full of water while not in demand.

I like how compact it is. It takes up a fraction of the space of my previous water heater. Very high quality and almost silent. Heats water very fast and it is super easy to use the settings. I drilled a hole through the back of the unit to run my electrical wire right into the box from inside the wall. Installation of the box itself was easy. The hard part was running 2 8 gauge wires through the wall and attic and back down into my electrical box. After that was done, I plumbed up the unit with corrugated stainless steel pipe and the brass isolation valves to perform the yearly descale.

The Tempra PLUS line is fantastic. It maintains a constant water temperature and adjusts flow rate if necessary. Be sure to check the charts on the manufacturer's website to help you decide which model to purchase (based on winter incoming water temps where you live AND the demand for hot water including number of faucets and appliances that are likely to demand hot water at the same time). This unit exceeds my expectations and I have endless hot water only when it is needed.

Installed June 2022 INSTALL NOTE - I am not a plumber and this stretched my mechanical DIY-er mentality, but I did install this on my own: be careful if you choose to install this on your own. I chose NOT to do the electrical upgrade required on my own - the risk of not getting that right was too high, so I paid my electrical contractor to upgrade the box for the 3 x 50 amp breakers - NO REGRETS! I knew my 55 gal standard electric water heater was not going to last much longer due to the units age AND the fact our local city water is awful with calcium and build up. I researched the available setups and units ad nauseum, and went with this unit: the brand recognition and reputation, the size due to our house and expectation that we will eventually sell it. When I bought this unit, it was one of the larger of its type and was actually cheaper than if I went with a standard water heater to match the one I was getting rid of. First, the drop in electric usage has about paid for 50% of the unit cost over the last year - yeah, THAT MUCH! Results will vary I am sure, but its just my wife and I in 2200 sq ft house, so the fact it runs "on demand" just makes sense. Another way to measure savings: I am all electric in this house and during extreme seasonal weather I could easily see a monthly electric bill $250-300, using either my heat pump or my additional heat source in the house. I have yet to see a monthly bill above $180 (Ohio weather from summer 90s down into the single digits in the winter). The temp control is amazingly simply - we found 115 works fine and can take a long hot shower. But I can walk out and dial it up or down if I chose. The install (outside of the electric) was not too bad. I have PEX plumbing in my house, so it was a no-brainer to use that with the majority of this project. I spent the money to buy heavy brass shot off valves (probably overkill) for the IN/OUT inlets on this unit. It will make a difference if I ever have to repair or replace the unit: I can easily isolate the unit from the flow of water. Assuming we will move in the future, I will be looking for a house that either has a tankless or can be upgraded to tankless: its a great decision and works amazing.

I love this thing! Install is not the simplest task in the world, but what a difference in space and performance over a tanked water heater. Once you get all of the details sorted out, the unit installation itself is fairly straightforward (although this DOES require quite a bit of preparation to install). Do yourself a favor and do your homework first before tackling this, but once it is done, you will be so happy! One thing to make sure of, if you buy the unit, register it right away as the warranty goes by purchase date. Updates to follow as time goes on.

First will say the only Con so far is when looking on here at the specs it actually calls for heavy wire the. What the manual said. I ordered my material also for the install when got it. Pros are easy to install and setup up, gets hot really fast and maintains temperature for as long as you need, and dropped are bill to the point in a year it has paid for itself plus you can write it off on taxes. I am a handyman/DIY with an electrical background so I did self install so would say hiring a professional is a must unless you have common knowledge of the trades needed. This would probably take longer to see savings than myself.

Excelente produto (fabricação alemã), muito bem construído, super robusto e com resistência blindada. Apresenta ótimo funcionamento, mantendo a temperatura desejada com grande precisão. Não há ruido algum durante o uso, sendo absolutamente silencioso, fácil de instalar e operar. O único incoveniente é o preço, mais elevado que os demais aquecedores, mas vale a pena. Faz juz ao slogan: simply the best!!
