Rated 2 out of 5 by from Ok for small home. Have had in use for 1 year. I am experiencing problems with 60amp breaker tripping around the 5 minute mark for every shower. When breaker is turned on, water is scolding hot, then will trip again during use. Have reached out to tech support. It was ok for first year. Don't count on this size for bathtubs or running 2 fixtures at the same time in southern Ontario. Had higher hopes for this product as I spent thousands upgrading to 200amp panel for the "future of electricity". Home depot staff could use more product training on this as they just read the description off the box to me.

Rated 5 out of 5 by from Tankless water heater We love our tankless water heater, no more waiting for 2nd person to shower, no worry about running out of hot water. Installation was easy peasy, ordering/delivery was great, during pandemic we still didn't wait long for product.

Rated 4 out of 5 by from Hot H2O Good product. Produces lots of hot water as needed. 5 people taking showers and it kept up well. 4 instead of 5 as the water temp gets hotter

I am looking for a tankless water heater for a two bedroom apartment that has a washing machine, shower and kitchen sink. The number of people are two adults with their young children (who often just bathe together). Is this water heater appropriate?

Asked by: Joce
The Tempra 24 Plus is a popular unit for a situation like this. If in Canada, it should produce around 3 GPM to work with depending on the time of year. IF you have any sizing questions, please feel free to call our Technical Support Department at 1-800-582-8423 Ext 6 Thank you

Are tankless water heaters suitable for use with private well water, or do they need city water with high water pressure?

Asked by: Jeannie
Your well still has the same amount of pressure as a city water system would have (or very close) Tankless water heaters only need a minimum of 30 PSI to operate. Your well system should be over this PSI and work fine with a Tempra water heater. Please feel free to call our Technical Support Department at 1-800-582-8423 Ext 6 with any questions. Thank you.

"See sizing guide to determine the best model for you". Okay, I give up - where do I find the sizing guide? (Is it in the manual?) Thank you.

Asked by: KevinD
Go to our website, www.stiebel-eltron-usa.com and on the Tempra page, it says "Sizing Guide." That should help you figure out which unit you will need. If you need further assistance, please call the office at 1-800-582-8423 ext 6. Thank you.

What do I do if after 1 year installed, the 60 amp breaker trips 5 minutes into running a shower every time? Once the breaker is turned back on, the water is scolding hot, will measure temps but too hot to hold hand under. Have descaled 2 times. Thanks

Asked by: Patrick
Please call the Stiebel Eltron Technical Support Department at 1-800-582-8423 ext 6 to discuss this matter. Thank you.
