It has worked great, very little maintenance. I live in an area with very hard water, so flush the unit with distilled white vinegar twice a year to keep it working like new. I can take a shower, do laundry and use my dishwasher at the same time and never run out of hot water. It has saved me a great deal of money versus my old electric hot water heater. This is a natural gas unit and uses so little gas, it has only raised my gas billed about $2 or $3 per month, when not in use, it is so much more economical than previous electric hot water heater. I can't say enough good things about it, love it. ### ⭐⭐⭐⭐⭐ ⭐ Rheem Tankless Water Heater – Peace of Mind and a Major Upgrade for My Family *by on Reviewed in the United States July 9, 2025* ⭐ Rheem Tankless Water Heater – Peace of Mind and a Major Upgrade for My FamilyA couple of months ago, our traditional water heater failed unexpectedly. We didn’t have hot water for days, and with a family of four, that quickly became stressful. I started researching alternatives and decided to try a tankless system—something more modern, energy-efficient, and ideally less prone to failure.I landed on this Rheem unit and took the plunge.⸻🛠️ My Setup ExperienceI’ve done some home improvement projects in the past, so I was comfortable tackling this. I took my time preparing and reading up on installation basics. It required planning—especially around venting and connecting to the existing setup—but once installed, the heater powered up, and hot water came on right away.One of the features I really appreciated was how compact the unit is. Once mounted, it freed up a lot of space where the old tank used to sit. I even took the opportunity to clean up and reconfigure the whole area—it felt like a reset for our utility space.⸻✅ Real-World Benefits We’ve Noticed• Hot water is always ready. No more cold surprises in the middle of a shower.• Energy efficiency – It only runs when needed, unlike tank heaters that constantly keep water warm.• Space-saving – It cleared out floor space and helped make the room feel more open.• User-friendly display – The interface is simple, and adjusting the temperature takes seconds.⸻💡 Lessons LearnedOne thing I really value is peace of mind—especially when I’m not home and my family needs something to work without fail. This unit delivered that. We’ve had guests stay over, and the system handled the extra demand effortlessly. My kids now even comment on how the water heats up “way faster than before.”⸻⚠️ A Few Tips• The unit does require a dedicated power source and venting, so plan ahead.• For homes with multiple bathrooms, I’d recommend checking the flow rate to ensure it fits your household needs.⸻🔚 Final Thoughts:This upgrade has made a noticeable difference in our daily routines. It’s dependable, efficient, and has already made our home feel a little more modern. I’m happy I made the switch and would definitely recommend this to anyone looking for a long-term hot water solution.⸻Let me know if you’d like this adapted for Inspire format, a quick summary caption, or a visual storytelling layout. ### ⭐⭐⭐⭐⭐ Great product/price *by on Reviewed in the United States July 25, 2026* Rheem has always made a great product and this unit is one of them ## Frequently Bought Together - Rheem RTG-70DVLN-3 High Efficiency Non-Condensing Indoor Tankless Natural Gas Water Heater, 7.0 GPM - HYDRO MASTER Tankless Water Heater Service Valve Kit with Pressure Relief Valve 3/4-Inch IPS Isolator Clean Brass - CMI Inc - 3/4 Inch IPS Female Threaded Complete Tankless Water Heater Valve Kit with Pressure Relief Valve Water and Gas Connectors - Compatible with Most Tankless Water Heater Brands --- ## 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.tn/products/578212056-rheem-rtg-series-7-0-gpm-natural-gas-tankless-water](https://www.desertcart.tn/products/578212056-rheem-rtg-series-7-0-gpm-natural-gas-tankless-water) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-26*
