Rated 2 out of 5 by from Note: Wiring is not included. Wiring is not included? I was expecting the wiring (pig tail) to be included. Went back to HD and was told that it was not included, needed to buy separately....but then no one at HD could find the correct wiring (premade) and suggested I make my own or go to an electrical supply store. Why is the wiring not included?

My power box only has the maximum of 100 amps. Will this unit work?

My power box only has the maximum of 100 amps. Will this unit work?
Asked by: Rosie
The big question you need to ask is, "Does your home have the appropriate gauge wire to carry the current?", otherwise you run the risk of burning your house down. This unit requires 6 gauge, most homes at best have 12 gauge running to the current water heater location, unless you built the placed and spec'd 6 gauge to your water heater. The problem is running that much current on a skinny wire may overheat the wire.

Wiring is not included, that is correct. You have to wire it yourself.

Asked by: Joat
any tankless installation should include a service valve kit (Rheem RTG20220AB available from HD). with this kit installed it is easy to isolate and drain the unit.

Can this be used for a above ground pool

Can this be used for a above ground pool
Asked by: Dee
Good day Dee and thank you for contacting Rheem through the Home Depot support. No, the Rheem 13 kw unit is only made for household use (sinks, showers). If you would like a pool unit, please contact our customer support at 800-374-8806 for proper sizing. The size of the pool and the amount of gallons will determine what size pool heater you will need. Thank you for your time.
