## Questions & Answers

**Q: Can this directly replace a 40 gal tank heater with a 30A double pole breaker? What are power requrements?**
A: No it can't. RTEX-24 requires 3 sets of wire and ground, and it needs 3x 40amp breaker.  That's a total of 120amps

**Q: Why are 2 answers for the breaker requirements. Is it 3 double 40 or 3 double 60 amp**
A: If the unit draws 40 amp. you need a 2 pole 40 amp breaker 2 #8 wires good for 40 amp and 1 # 10 wire for a bond. Now if the unit draws 60 amps you need 2 # 6's good for 65 amps. A 2 pole 60 amp breaker and 1 # 8 for a bond( ground wire).

**Q: Has anyone had a noticable difference in electric bill?**
A: Yes, reduced electricity by about 20%. But this thing sucks. It has trouble keeping up with water flow and is noisy.  Their support is atrocious. I would not recommend it. Select a different brand.

**Q: Can the unit operate as a rtex-18 if i only hook up 2 of the elements? because i only need the 18 specs as of now but would like the option to upgrade**
A: Actually you can do this but you must be careful on which circuits are connected. Rheem says the elements are activated from right to left as power is required. The right most element connection also provides power to the control so this must always be connected. If the very left element is left disconnected, you will only get 2/3 of the rated power on a 3 element unit.
