Asked by Offthegrid February 3, 2019

Answer

3.5 GPM is outside of the national standards for a shower head, our sizings are based on max 2.5 GPMs, for temperatures that hot there may need to be some additional actions taken. We wouldn't recommend for residential applications having temperatures this high 125 degrees could scald someone. You may need to contact a local pro to discuss your application. --Tashay

Can you still use a water softener with a tankless water heater?

Asked by Chris January 8, 2019

Answers

Yes, the more neutral the water that goes thru the tankless heating chambers, the longer your unit will last. Even so, you still need to flush the tankless unit yearly.

Great tankless hot water...
I've had my water heater for about 2 months. It freed up a lot of space in my house and has lowered my electric bill substantially. I'm very happy with the capability and the operation of the equipment.

Unlimited Hot Water
Everyone in the family gets hot water for their bath or shower. No need to fight who goes first or dissappointment of going last.

Have replaced about 4 times in 14 years -heated well during long winters with -40 degree cold spells. (If memory is correct, one lasted 7 years.) I am realistic and thankful for my Rinnais.

Perfect Vacation Home System
Had first Rinnai for 15 years. The new one more than meets expectations. Excellent system for a vacation house where you do not want to be heating water all of the time.
by BeachGuy8658
This is our third one
Installed one on the renovation of second home. Then added a three-quarter bath on other end of home with its own Rinnai. Finally installled one at our primary home. Absolutely great.
by Repeat3066
This Rinnai product does not work in our home and
It is small and tidy against the wall. We don't like it because you have to run up to 4 gallons of cold water to get to hot water. There are some faucets where it takes over 10 minutes for the water to get hot. At this point we don't know if it is a defective unit. We have a ticket and we are fact finding.
