How long can the run before performance is affected. My master is about 50 - 60'.
Asked by: hj
You may have to wait about 10 to 15 seconds before the hot water kicks in but oh yeah, you will be happy. Now I live in Miami so the pipes do not get cold.

Tempra 20 Self-Modulating 19.2 kW 3.90 GPM Electric Tankless Water Heater is rated 4.2 out of 5 by 13.
Rated 2 out of 5 by from Unit failed after less than 2 yrs. Warranty only covers parts. Not labor and not shipping. Parts ... Unit failed after less than 2 yrs. Warranty only covers parts. Not labor and not shipping. Parts are not available in Phoenix, have to be shipped from Massachusetts. So $150 for install and $97 for 2 day shipping. They send the wrong parts. Second time they will pay shipping but it's Friday so no parts til Monday, fixed on Tuesday. Wrap-up is $247 to fix a unit under manufacturer's warranty and a week without hot water. OK when it works but after this, would not buy again.

Rated 5 out of 5 by from Hard to believe I was cramped for space in my utility/laundry room. I removed my old gas hot water tank that was 15 years old and due for replacement. I had explored my options. Home Depot. com always had the answer and many choices. Easy install with the proper pex, and electrical tools (knowledge in these fields is a MUST). The Origin, Made in Germany says it all. They have been making energy saving products for nearly 90 years. Great Product!!!!

Rated 5 out of 5 by from Easy to install Started it up today. Very easy to install. The plumbing connections were easy. An electrician did the required upgrades for the power (from the lesser requirements for the tank heater we had). Easy to use and set.

Rated 5 out of 5 by from Why do they make the large tanks when they have these? We bought our 3 bdrm, 2 bathroom condo about 6 months ago with a very small kitchen with little cabinet space. i don't understand why more people don't have these! We never run out of hot water or have an issue with having enough.

Rated 5 out of 5 by from The system has been installed for one month and works great The Temperature control is excellent it provides the ability to adjust the temperature within a few degrees
Date published: 2012-09-04
Rated 4 out of 5 by from Compact, heats water quickly I did the installation myself with average skill & tools. The required heavy gauge wires are expensive, so add that in to your total cost. Also, check to see how many (1-3) SEPARATE electrical circuits are required for the chosen heater. This one heats water quickly; the shower is 10ft away and it takes about 10 seconds for the hot water to start flowing. Have not tried multiple hot water devices (shower, dishwasher) at the same time.

Rated 5 out of 5 by from Great product! Works great! We did need an electrician and plumber to install. Works well in our one bathroom condo.
