What is the gpm rating on this?
That will depend on the temperature differential desired. Refer to the chart posted in the pics.
The minimum flow rate to power this on is 0.5 GPM.
27KW = 27000 watts @ 240 volts works out to 112.5 AMPs. I hope your electrical services can cash that check.
Does the water heater have a manufacturers warranty? For how long
Will this unit power a whole house? I have a tankless now in the garage but my master bath is upstairs. I get no hot water to the sink and in the S. Fl. winter my water is only lukewarm in my shower. I want a unit that works well with lowflow shower heads. I lived in Europe and always had amazing endless hot water with the systems there.
Hi there. We list the warranty at the bottom of the features. This has a 90-day Woot warranty.
Working good upstairs and down Stairs
