No concerns about when to take a shower or washing the dishes! Just need to get use to the adjustment of the hot water control as if someone would to was the dishes as I’m taking a shower, you can feel the temperature change! Just a minor adjustment! Need to also consider the cost of electrician and plumber! Need to install correctly,

Easy to install for a DIYer, just obviously use your judgement about electrical safety and wiring this into the main fuse panel.

Installation was well explained and tech support was terrific. I live in Key West where incoming water is never below 80 degrees so I have been able to sustain 5-6 gallons per hour at 110 degrees.

    My house is at 16 outside it is -6 right now but we get like -30. I have a 3 story home with 1 bathroom on top floor and kitchen sink on main floor. Would this work or do I need to buy 1 for each floor that needs hot water?

    Asked by: Laurie
    With cold incoming water temperature like you have (ground temperature being much different then air temperature) The Tempra 20 Plus would provide you with about 2 Gallons Per minute to work with. If you are running one fixture at a time and is has an aerator of 2.0 GPM then this unit should work just fine. Please feel free to call our Technical Support Department at 1-800-582-8423 ext 6 with any further questions. Thank You!
