Questions & Answers

I have a seasonal home. I drain my water lines in the winter. Is it ok to leave the unit installed? I am replacing another brand. It froze and broke.

I drain and blow the lines with compressed air.
Asked by: Pablok54
I drain my lines in winter, I do not blow them out, nor have i ever disconnected lines to heater and drained. I should add my 400sqft cottage built on slab and completely insulated.

Can this unit be installed outside the house? I live in southeast Texas and it rarely freezes here.

These units need to be protected from the elements. They are not weather proof and have openings in which small critters can climb into. Customers have installed them on the outside of the house but have build and installed them into enclosures to protect the unit from these issues. Please feel free to call us at 1-800-582-8423 ext 6 with any questions. Thank you.

What is the difference between the tempra 20 plus and the tempra 20?

Asked by: Leedarr
Plus models have an automatic control that will maintain hot water temperature by reducing the flow rate if too many taps are turned on. A good example is if someone is in the shower, and someone else turns on the kitchen sink and overloads the water heater. The person in the shower doesn't get a shot of cold water. The water temp from both the showerhead and the kitchen sink are at the set temperature of the water heater, but the flow rate is automatically adjusted so less water comes out. Once the kitchen sink is turned off the showerhead goes back to normal and the water temperature never changes. The basic models don't have this feature.

Rated 5 out of 5 by from Great Electric Tankless HWH The Steibel Eltron was one of the few brands that seemed to know what they were doing when I originally wanted to purchase a Tankless Water Heater. I bought this to replace an existing 40 Gal. HWH that was not properly winterized and was destroyed when the foreclosed property I purchased had been abandoned about 8 months before I bought it. I installed the unit in a 100 Amp box on 2-50 Amp breakers, so in theory, it could potentially use all of the power in my home, but I have never had any issues with power when people are taking a shower and the microwave is being used, or any other major power draws are happening. I can't really speak to issues of flow, but there have been as many people as 4 living in my home at one time, and I think the bigger issue tends to be when other people draw cold water and the mix gets changed in the shower. I have also installed a low-flow (pressure adjustable) Kohler Shower Head, and Aerators at the main faucets, which help limit flow, but getting enough hot water has never been a problem. I actually tended to have issues with not drawing enough water flow through to kick it on, which might be my only grief with the unit. If I just want a small amount of hot water to rinse dishes or the like I sometimes need to fiddle around with it or kick it on higher to get the HWH to kick on. Anyway, my unit was installed in June of 2008 and I've had no issues with it since. I'd highly recommend.
