      I bought this tankless hot water heater because it was time to stop heating fifty gallons of water 24/7 when I really only need it twice a day. I did my homework and decided the Tempra 24 was most suited to my home (one adult, two teenage daughters, two bathrooms). Installation was quite simple; I did my own plumbing and electrical installation following the instructions. Within twenty minutes of finishing the wiring, I had bled the lines and my 15 year old daughter was in the shower—what better test? She emerged twenty minutes later declaring it an unqualified success, and she didn't even know I had washed the dishes while she was in the shower. It's been a month now, and the heater has met every challenge. Twenty years ago I installed a tankless hot water heater in a new home I built, and it was satisfactory, but had issues. There is simply no comparison—in both manufacturing and performance, this is light years ahead. I set the temperature at 116 degrees and it maintains it perfectly all the time. My main concern was warm water at the sink—since the sink is served by smaller lines, would I draw enough flow to activate the heater? Turns out I did, no worries at all. I've already urged everyone I know to go tankless when it's time to replace their heater—or sooner. And I will be pleased to recommend Stiebel.
