Tempra 29 Steiebel Eltron Electric Tankless Water Heater Today I took my first shower with the water being generated by our new Stiebel Eltron Tempra 29 Tankless Water Heater. I was very worried that the system couldn't generate enough hot water to give me sufficient pressure, but thankfully I was wrong.

Because the water was 125° F, I had to use a good deal of cold water to make the shower comfortable, which added to the overall pressure as well. Once I got the temperature just where I wanted I enjoyed a nice long shower, never having to stop and adjust the temperature like I normally did when the hot water would start to dwindle.

My next test of the unit will be taking a shower while running a faucet at a sink. I imagine it will drop the water pressure, which will in-turn throw off my hot-to-cold water ratio, making my shower a little colder. I hope that a slight adjustment in the cold water will quickly fix the problem.
