## Description

The Rheem Performance RTEX-24 is a 24 kW tankless electric water heater ideal for whole-home applications. Rheem tankless electric water heaters offer a continuous, endless supply of hot water. A lower kilowatt unit can provide hot water on demand for single or multiple point-of-use applications while a higher kilowatt unit could provide hot water for a whole house depending on the inlet ground water temperature. Tankless electric water heaters save space, save energy, save money, and require no venting. The sleek, compact size, 90 percent smaller than a tank, allows you to save space and place the unit wherever you want, including under a sink. Tankless units only draw energy when hot water is flowing, while traditional tanks are constantly drawing energy to keep the water in the tank at the desired temperature. Rheem's self-modulating technology can save Up to 50 percent on your water heating bill.

## 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.

ES IMPORTANTE CONOCER LAS ESPECIFICACIONES Y TENER UN ASESORAMIENTO DE COSTOS ANTES DE COMPRAR MI EXPERIENCIA FUE MUY TRISTE PORQUE COMPRE EL PRODUCTO CON MUCHA ILUSION Y RESULTA QUE LA INSTALACION ME IBA A COSTAR 3 VECES QUE EL COSTO DEL CALENTADOR. LO TUVE QUE REGRESAR ESPECIFICAMENTE EL PROBLEMA FUE LA ESPECIFICACION DEL CABLE EN RELACION AL AMPERAJE DEL PRODUCTO
