After a bad experience with our last one (different brand) we are so impressed with this one and hope it last us a long time! We have a 3bd 2ba and it keeps up with our water! Review: Tankless Hot Water install - I replaced a 55 gallon hot water tank with this unit, I bought a little larger unit than what the ratings said I needed to be safe. Make sure you check your electrical panel to make sure you have room for 3 x 40 double pole 40 amp circuit breakers. I didn’t have enough room, had to add a sub panel plus had to run 9 x 8 gauge wires the unit requires. I’m pretty handy, but asked a certified electrician to help me with the pre wiring. To be honest, I would have been afraid to try and do this myself even with all my experience. Installation was pretty simple after you have the wiring installed. Use 1 inch piping from your electrical panel to the tankless electrical unit or you won’t be able to pull the nine 8 gauge wires through the pipe. I also suggest having an electrical panel with a main breaker so you don’t have to shut the whole house down for the final install. Additionally i installed a surge protector to hopefully protect the unit from power surges which appears to have delicate electronics inside. We’ve only had this unit in operation for 4 days so far, but the water is really hot, have had no issues at this point and I love the added space gained without having the tank. Time will tell if we save 50% on energy, but from all my research it makes sense even with us living in a warm climate. There are several tankless unit manufacturers with great ratings, I went with Rheem because if I have an issue, they are based in the USA and hopefully that means English speaking in my time zone….. Hope my review is helpful to you. Update: it’s been 7 months, still works great, very happy with this decision even though I can say I’ve seen significant energy savings ## Features - ELECTRICAL REQUIREMENTS: 1 x 30 AMP Double Pole Breaker Required.

One of them provides adequate hot water for a small home (2 adults) having a shower, lavatory, kitchen sink, dishwasher, and clothes washer. Although it can draw up to 46 amps, the 100 amp main breaker has never tripped in spite of having an electric stove, air conditioner, clothes dryer, and refrigerator/freezer. The customers are delighted even after three years of constant use. A central location is important, as is minimizing piping bends. Be sure not to overtighten the compression fittings at the entrance and exit of the device. A clog in the shower head caused the heater not to work (as designed) due to low flow. My guess is that anyone having problems usually has an upstream or downstream issue not related to the proper performance of the heater. ## Frequently Bought Together - Rheem 3.5kW 120V Point of Use Thermostatic Tankless Electric Water Heater - HYDRO MASTER Tankless Water Heater Service Valve Kit with Pressure Relief Valve 3/4-Inch IPS Isolator Clean Brass - Rheem 6.5kW 240V Point of Use Thermostatic Tankless Electric Water Heater --- ## 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.ae/products/635472121-rtex-04t](https://www.desertcart.ae/products/635472121-rtex-04t) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-04-23*
