Q: How many amps are needed for rheem rtex - 13 240v heating tankless electric water heater

Hello-The RTEX-13 requires 1x 60A@240V breaker / 6 AWG recommended wire size.Specs - http://cdn.globalimageserver.com/fetchdocument-rh.aspx?name=Specification-Sheet&id=fc3235b7-7cd0-42cd-93bc-7169ea92be31 Rheem 800-432-8373I hope this helped :)Ben

Q: Do these tankless water heaters require an overflow line to the outside of the home or a pan like is required on normal water heaters ?

No tank, so, no overflow line required. It mounts on the wall. A pan is needed if required by building code in your city.

Q: We have a 500sq' apt. 1 kitchen sink, 1 lav sink and tub/shower. This tankless heats water to both sinks but nothing to the tub/sh. Help

Sinks have aerators to slow down the water where a tub doesn't. It sounds like one possibility is that your exceeding the GPM for this heater. Next possibility, double check an measure your actually getting at least 240v at the heater, I had an issue where my unit was only getting 235v an it was causing a similar issue where only one of the two heating elements was activating. I had it set to 125F but it was coming out 100F. It was warm and without a meter I would of thought it was working correctly until I tried filling a tub. It couldn't even get the water warm. I pulled my wires out an restripped an cut an screwed them in an it fixed my problem, now its measuring around 245v. Make sure there is no copper showing after screwing down your input wires. Now filling the tub I noticed after about 10-15 seconds the water gets too hot to touch. I set it to 135F.

Q: El titan n270 me puede alimentar 3 baños y agua caliente en toda la casa.

Solo tengo un baño y me sirve muy bien el calentador. Mi casa es pequeña. I'm sorry.
