Seems like the description is all messed up? To hard wire is it 1 hot, 1 neutral, & 1 ground?** A: 120v…yes **Q: The med setting on my atmor inline 800 240 volt 13kw don't engage** A: not sure why the middle setting won't work when the other settings will work, probably has something to do with the amps going into the system, it would set it off as the amp are either too low or too high.. **Q: Can this unit be installed as a booster for a faucet far away from the current hot water tank? Will it shut off when the supply water is hot?** A: No, This unit turns on when a faucet is opened, pressure drop, not water temp. You need a small point of use heater for your remote sink. **Q: I installed this heater on Friday, today is Wednesday and this morning it is not working. how do i get this replaced. It has a dedicated 30amp breaker** A: Return it and buy a different brand. I bought it but never installed it just returned for one with metal internal parts because my plumber saw it and said it was too cheaply made it won’t last. I was lucky. ## Frequently Bought Together - Atmor 3500Watts/120V 0.5GPM Point-Of-Use Electric Tankless Water Heater Includes Pressure Relief Device 1-Sink Water Heater, Pressure Relief Valve Included - Rheem 18kW 240V Tankless Electric Water Heater, Gray - HYDRO MASTER Tankless Water Heater Service Valve Kit with Pressure Relief Valve 3/4-Inch IPS Isolator Clean Brass --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/277444333-atmor-3500watts-120v-0-5gpm-point-of-use-electric-tankless](https://www.desertcart.us/products/277444333-atmor-3500watts-120v-0-5gpm-point-of-use-electric-tankless) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
