I h ave decided to go with a tankless (that is not my question) but I need help sizing it.
I live in Salt Lake City. The winter water temp averages 46 degrees but can be as cold as 34. I like HOT showers, and will have two showers going at once every day. So probably a max of 5gpm most of the time.
I decided on the Noritz 931 since it can raise the water temps about 75 degrees when 5.6 gpm are flowing. It is 84% efficient
BUT...that model does not qualify for the $300 tax credit. Do you think I will be happy with the Noritz 841 which will raise the temps 75 degrees when 5.0 gmp are flowing? It is 93% efficient. Do you think that will raise the temp enough for a HOT shower when two showers are going? Also ss the efficiency rating between these two units (84 vs 93) enough to notice a difference in my gas bill?
Thanks in Advance. I have to decide this week so any help would be great!
